This diploma thesis deals with sensory evaluation of herbal non-alcoholic beverages, being a part of a new product development. The theoretical part provides information concerning chemical composition, health effects, food applications and aroma compounds of the herbs of interest (peppermint (Mentha piperita), sage (Salvia officinalis), St. John’s wort (Hypericum perforatum) and lemon balm (Melissa officinalis). Another topic is a description of sensory methods, requirements and arrangement of the analysis, statistical methods, and also technological processes leading to herbal syrups and beverages production. The practical part comprises sensory analysis of a few, newly designed, formulas of one-component and two-component alcohol free herbal beverages. The sensory panel consisted of 40 students of master's and also doctoral study programme at Faculty of chemistry, University of Technology Brno. Four subsequent experiments are introduced, each of them consisting of a few sensory tests and including corresponding sensory forms attached. The sensory tests arrangement was based on currently valid Czech Technical Standards, using a ranking, descriptive, paired comparison, sensory profile testing and scaling methods. For the purpose of statistical evaluation, Friedman, Kruskal-Wallis, PCA and Faktor analysis were used. Level of abilities and sensory experience of panelists were found comparable to consumer testing. The results include sensory characteristics of all of the beverages tested. In general, the one-component beverages were preferred to the two-component beverages and the additive colouring with aronia concentrate wasn´t found any benefitial, from the sensory point of view. The consumer questionnaire proved all of the samples to be very promising, but based on the sensory results, we would consider the mint and the sage-mint beverages being the most potentialy applicable samples.

In addition, it was identified that many of them value their time and therefore turn to the web pages to make purchases of products and request delivery service. Finally, it was found that many users consume filters either to relax, discomfort, however, there are no filters that contain dehydrated fruits that give that special touch. Therefore, to start this project an analysis of the industry was carried out Customer, suppliers, competitors and other factors. In addition, the following plans were developed: Strategic Plan, Operations Plan, Marketing Plan, Human Resources Plan, Social Responsibility Plan and the Financial Plan. Which include the indispensable strategies for the viability of this project. The product will be promoted through virtual platforms, that is, social networks such as Facebook and Instagram. Likewise, it will be marketed through stores, fairs and Courier service. Finally, the financial analysis performed as a study of the project has an opportunity cost of capital (COK) of 17.77%. In this way, we can conclude that the development of the company HAMPIY SAC is economically viable. / Trabajo de investigación

In this research we aimed to investigate the anti-proliferative properties of three South African plants: Kedrostis foetidissima, Euphorbia mauritanica and Elytropappus rhinocerotis against breast cancer cells. This was done on the basis of their documented ethno-medicinal use against cancer and other ailments. The plant extracts were screened for cytotoxicity and pro-apoptotic activity against two breast cancer cell lines MCF-7 and YMB-1. With an IC50 ~ 100 μg/ml, K. foetidissima was the only extract that exhibited significant cytotoxicity on both cell lines, whilst E. mauritanica was cytotoxic to MCF-7 cells only. The cytotoxicity assay was followed by the Annexin-V detection assay to evaluate the occurrence of apoptosis. The results observed suggested that K. foetidissima was inducing significant apoptosis on both YMB-1 and MCF-7 cells, whilst E. mauritanica was inducing significant apoptosis on MCF-7 cells. Since both K. foetidissima and E. mauritanica crude extracts induced apoptosis to MCF-7 cells, they were selected for gene expression studies on MCF-7 using real-time PCR. This was done with the aim of investigating if these extracts were having an effect on the tumour suppressors p53 and RBBP6, which were shown in previous studies to be deregulated in up to 50% of cancers. From the real-time PCR data we observed no changes in the expression levels of these genes following treatment with the herbal extracts. This may suggest that these plants have an effect on other components of the apoptotic pathway other than the tumour suppressors p53 and RBBP6. The antiproliferative activity observed whilst treating these particular cell lines with K. foetidissima and E. mauritanica suggests that these South African herbal plants present themselves as potential future cancer therapeutic agents; however, further studies on these herbal plants need to be performed to validate these results.

The herbaceous Atriplex species which occur in Utah are revised. This study is based on herbarium specimens and field observations throughout the state. My treatment largely follows that of Rall and Clements (1923). A brief discussion of the history, diagnostic characteristics and phylogeny is given. A descriptive key that includes all taxa has been prepared: type locality, synonyms, general habitat and distribution is reported for each entity. Illustrations and maps are included. One variety is described as new.

Responses to drought were studied on greenhouse grown plants of Sphaeralcea grossulariaefolia (Hook. & Arn.) Rydberg. A pressure bomb was modified to measure leaf water potential (ψ). Leaf water potentials varied from -2 to -80 bars. Matric potential proved negligible. Low osmotic potentials indicated that turgor pressure remained positive. Photosynthesis decreased linearily with leaf water potential decreases. At about -32 bars ψ net photosynthesis became zero and around -45 bars ψ all photosynthesis ceased. Dark respiration decreased below about -18 bars proportionally to leaf water potential decrease until becoming minute at -60 bars. A very rapid rise in CO2 equilibrium concentration occurred as leaf water potential decreased below -18 bars. Abscission of leaves began at -6 bars ψ. At -32 bars ψ only about 15 percent of initial leaf area remained. A close balance between transpiration and soil moisture absorption was maintained by stomatal closure and leaf area abscission. Upon watering, rapid regeneration of foliage following severe drought was especially notable. Growth characteristics related to drought and possible indexes of physiological vitality were discussed.

and senkyunolide A were found as the three major compounds in all herbal samples investigated. In addition, great variations in both total and individual content of each of the ten main components investigated were observed in samples of different origins and those collected from a GAP developing base in the same or different years, suggesting the necessity of a thorough quality control for Rhizoma Chuanxiong. / Extraction of the main ingredients from Rhizoma Chuanxiong by supercritical fluid extraction using CO2 was investigated. An appropriate SCFE method for Chuanxiong was developed with the mild conditions for the extraction of the unstable components. The method provided a high recovery and adequate reproducibility, and may be suitable for large-scale industry extraction of Chuanxiong. / Firstly, a total of sixteen ingredients were identified from Chuanxiong by HPLC-UV-MS and HPLC-UV analyses. Among them, ten ingredients were determined to be the main components in Chuanxiong. A simple, sensitive and specific HPLC-UV method was developed, for the first time, to simultaneously qualitatively and quantitatively determine twelve ingredients, including the identified ten main ingredients, plus vanillin and tetramethylpyrazine (TMP), which although were not found in the present study, had also been reported to be present in Rhizoma Chuanxiong. The developed assay was fully validated and provided adequate accuracy and reproducibility for all compounds analyzed. It was applied successfully to simultaneously quantify all main constituents in different Chuanxiong samples. TMP and vanillin were not detected, while Z-ligustilide, coniferylferulate. / Furthermore, a comprehensive stability study was carried out for the first time with the three major components senkyunolide A, coniferylferulate, Z-ligustilide and the main ingredient 3-butylidenephthalide, in pure form or Chuanxiong extract obtained from supercritical fluid extraction using CO 2 (SCFE) under different conditions. Results showed that both sun light and elevated temperature led to degradations of these components to different extents. Owing to such thermal and light instability, post-harvest drying and processing procedures could significantly alter the chemical profile of Chuanxiong herb, and thus also need to be well controlled. / In conclusion, analytical and pharmacokinetic studies of the main chemical ingredients in Rhizoma Chuanxiong were systematically conducted. The results revealed, for the first time, that senkyunolide A, Z-ligustilide and 3-butylidenephthalide might be the primary chemical ingredients contributing to the beneficial effects of Chuanxiong. / Oral bioavailability was about 8%, 3% and 20% for senkyunolide A, Z-ligustilide and 3-butylidenephthalide, respectively. Instability in the gut mainly contributed to a low oral bioavailability of senkyunolide A. First-pass metabolism in the liver also contributed to the low oral bioavailability but to a much lower extent. For Z-ligustilide, extensive first-pass metabolism in the liver and degradation in the stomach only partly accounted for its poor oral bioavailability, while other gut factors involved are still unknown. In the case of 3-butylidenephthalide, its low oral bioavailability was attributed to extensive first-pass metabolism in both the gut and the liver. / Pharmacokinetic fates of the main ingredients in Chuanxiong SCFE extract were firstly evaluated in rats. After a single intravenous and oral administration, only senkyunolide A, Z-ligustilide and 3-butylidenephthalide were determined as the main herb related components in plasma. Coniferylferulate, although it is one of the abundant principles in the herb, was not detected in the plasma even immediately after dosing. / Pharmacokinetic profiles of senkyunolide A, Z-ligustilide and 3-butylidenephthalide were further elucidated individually in rats. All three compounds exhibited rapid absorption, extensive distribution, and rapid elimination. The pharmacokinetic profile of senkyunolide A followed a dose-independent pattern, whereas Z-ligustilide exhibited dose-dependent kinetics. 3-Butylidenephthalide underwent enterohepatic re-circulation. / Rhizoma Chuanxiong is derived from the dried rhizome of Ligusticum chuanxiong Hort. (Umbelliferae). In China, it has been widely prescribed for the treatment of cerebro- and cardio-vascular diseases for thousands of years. However, its chemical and pharmacological basis is poorly understood. In the present study, analytical methods for qualitative and quantitative determination of the main chemical components in Chuanxiong herb were developed. Furthermore, pharmacokinetic profiles of the main chemical ingredients in Chuanxiong were systematically investigated in rats for the first time. / The metabolic profiles of senkyunolide A, Z-ligustilide and 3-butylidenephthalide were investigated both in vivo and in vitro. Oxidation and hydration were found to be the main metabolic pathways for all three compounds. In addition, glutathione conjugation of senkyunolide A and Z-ligustilide also occurred in the rat. A novel metabolite 3-hydroxy-3-butylphthalide was identified as the major metabolite of 3-butylidenephthalide generated by a direct hydration, and was shown to have significantly higher plasma levels than those of the parent compound. Furthermore, the main metabolites detected in the plasma of rats administered with Chuanxiong extract were generated from senkyunolide A, Z-ligustilide and 3-butylidenephthalide. / Yan Ru. / "May 2005." / Adviser: Ge Lin. / Source: Dissertation Abstracts International, Volume: 68-03, Section: B, page: 1583. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2005. / Includes bibliographical references (p. 244-255). / Electronic reproduction.

Bi-directional transport studies in SimBioDASRTM and Caco-2 cells were employed to examine the transport profiles of Buph, Ligs and SenA. Apical to basolateral (A-B) transport studies of the tested compounds revealed high intestinal permeability and predicted human absorption of over 98%. Permeability ratio of B-A/A-B of Buph (0.7-1.3) and Ligs (0.8-1.2) indicated that they were transported by passive transcellular and paracellular pathways while the low B-A/A-B ratio of SenA may imply possible involvement of other transport mechanisms. One metabolite (M-1) generated from hydration of Buph was observed in Caco-2 cells and the fraction of metabolism was 12.5% (A-B). / In conclusion, Buph, Ligs and SenA were predicted to have good intestinal absorptions in human and rat. However, extensive hepatic and intestinal first-pass metabolism of Buph in rat and human were found to cause its low oral bioavailability. On the other hand, certain degree of hepatic first-pass metabolism of Ligs and SenA may account for the partial loss of drugs via oral administration to rat. Therefore, other routes of delivery, such as sublingual administration, are worth to be considered to improve the therapeutic effects of chuanxiong. / In the rat SPIP, permeability calculated from the appearance of Buph in mesenteric blood (Pblood) was 6.0+/-1.7 x 10-4 cm/s while the fraction of formation of M-1 was about 7.1%. Together with the in vitro results, it is proposed that first-pass metabolism of Buph was present in human and rat small intestine. Moreover, Ligs and SenA had high Pblood values of 4.2+/-1.2 x 10-3 cm/s and 3.8+/-2.8 x 10-3 cm/s, respectively, indicated that they were highly permeable across rat intestinal mucosa. No metabolism of Ligs was observed. But several metabolites of SenA were detected despite they were not quantified in the present study. / In vitro metabolic studies of Buph demonstrated that major metabolite M-1, which was also found in Caco-2 cells and SPIP, formed mainly in intestine and liver cytosol in rat and human. The intrinsic clearance (Vmax/Km) of Buph was extensive and similar in both organs, and its extent in human was comparable to that in rat. The sum of the estimated in vivo extraction ratio of Buph by liver (48.3%) and intestine (55.0%) was higher the loss via oral administration to rat (77%). On the other hand, several metabolites of Ligs and SenA were found in rat and human liver microsome but not in intestinal preparations. The estimated in vivo extraction ratio by liver of rat was 47.3% (Ligs) and 22.9% (SenA), respectively, which were less than the corresponding loss via oral administration to rat (Ligs: 92.2% and SenA: 97.7%), suggesting that first-pass effect other than metabolism of these two compounds in intestine also contributed to their low oral bioavailability. / Rhizoma chuanxiong is commonly prescribed orally for improving blood circulation and treating cardiovascular disorders in China. Like other traditional Chinese medicines, chuanxiong has been used for thousands of years in China but its chemical basis, pharmacological effects and pharmacokinetic fates of the active ingredients, especially absorption, are poorly understood. Recently, seventeen compounds such as 3-butylidenephthalide (Buph), Z-ligustilide (Ligs), senkyunolide A (SenA), vanillin (Vani), ferulic acid (Fera), senkyunolide I (SenI), senkyunolide H (SenH), coniferyl ferulate (ConFer), sedanolide (Sdan), riligustilide (Rili) and levistolide A (LevA) have been isolated and recognized as the main constituents of chuanxiong by our research team (Li et al., 2003). Moreover, it has been demonstrated that Buph, Ligs and SenA are bioactive components of chuanxiong for vasodilatation and anti-thromboembolism (Chan, 2005) though their oral bioavailability in rat are very low (2.3, 7.8 and 23% respectively) (Yan, 2005). Therefore, the present study aims at investigating the intestinal permeability of the major ingredients of chuanxiong and characterizing the intestinal absorption and first-pass metabolism of Buph, Ligs and SenA by in vitro Caco-2 cell monolayers, SimBioDASRTM , in situ single-pass intestinal perfusion (SPIP) in rat and in vitro metabolism using rat and human intestine and liver subcellular fractions respectively. / Using the in vitro cell monolayers of SimBioDAS RTM, the intestinal permeability of major components of chuanxiong ranged from 12.2+/-1.6 x 10-6 cm/s to 70.6+/-9.6 x 10-6 cm/s with a rank order of Fera < Buph < Ligs < Sdan < SenH < SenI < SenA < Vani. They were predicted to have over 70% absorption in human. However, ConFer, Rili and LevA were estimated to have poor human oral absorption. / Ko Nga Ling. / "September 2005." / Adviser: Ge Lin. / Source: Dissertation Abstracts International, Volume: 68-03, Section: B, page: 1577. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2005. / Includes bibliographical references (p. 215-239). / Electronic reproduction.
