Estudos fitoquímicos e avaliação do potencial anti-helmíntico da opuntia ficus-indica /Féboli, Aline. January 2015 (has links)
Orientador: Rosangela da Silva de Laurentiz / Banca: Luciano Alves dos Anjos / Banca: Vanessa de Andrade Royo / Resumo: A Opuntia ficus-indica (O. ficus), pertencente à família Cactaceae, é uma planta nativa do México e conhecida no Brasil como "palma forrageira. Esta planta apresenta propriedades medicinais interessantes. O. ficus tem um bom potencial nutritivo é fácil cultivare muito utilizada na alimentação de pequenos ruminantes especialmente em zonas áridas do nordeste do Brasil. Embora esta planta seja usada como alimento para ovinos, a literatura não contém quaisquer relatórios sobre as suas propriedades anti-helmínticas. Portanto, este trabalho teve como objetivo avaliar a atividade ovicida e larvicida da O. ficus por meio dos extratos hidroalcoólicos de cladódios e frutas em ensaios de eclosão dos ovos (EHA), desenvolvimento larval (LDA) e migração larval (LMIA) usando ovos e larvas de nematoides gastrointestinais de ovinos naturalmente infectados. Para o EHA foi observada uma inibição da eclodibilidade de ovos maior do que 90% para ambos os brutos extratos dos cladódios e frutos na concentração de 50 mg/mL ou mais elevada (p <0,05). Ambos os extractos mostraram uma resposta dose dependente com o mesmo valor de IC 50 de 9,9 mg/mL. No LDA, o extrato hidroalcoólico bruto dos cladódios mostrou 98,7% de inibição do desenvolvimento das larvas a 12,5 mg/ml, enquanto o extrato hidroalcoólico bruto dos frutos apresentou 100% de atividade a 50 mg/ml, respectivamente, com um IC 50 de 3,4 mg/ml e 3,7 mg/ml (p <0,05). No LMIA, os resultados foram maiores do que 65% de inibição da migração das larvas na a parir da concentração de 1,56 mg/mL com IC 50 de 0,35 mg/mL e 0,76 mg/mL, respectivamente para os extrato brutos dos frutos e cladódios. O fracionamento dos extratos hidroalcoólicos brutos dos frutas e cladódios forneceu quatro fracções. Entre os extratos fraccionados, os extratos aquoso residual e em acetato de etilo dos cladódios, na concentração mais baixa testada (1,56 mg / ml) resultou em 100% de inibição do... / Abstract: Opuntia fícus-indica (O. ficus), which is native to Mexico and is known as "palma forrageira" in Brazil, is a species belonging to the family Cactaceae. This plant displays interesting medicinal properties. O. ficus display good nutritional potential is easy to cultivate and is used as feed for small ruminants feed especially in arid areas of northeastern Brazil. Although this plant serves as food for sheep, the literature does not contain any reports on its anthelmintic properties. This paper reports on the ovicidal and larvicidal activity of O. ficus from hydroalcoholic extracts of cladodes and fruits through egg hatch assay (EHA), the larval development assay (LDA), and the larval migration assay (LMIA) using eggs and larvae of gastrointestinal nematodes of naturally infected sheep. For EHA was observed an egg hatch inhibition greater than 90% for both the crude extracts of cladodes and fruits when using a concentration of 50 mg/mL or higher (p < 0.05). Both extracts showed a dose-dependent response with the same value to LD 50 of 9.9 mg/mL. In the LDA, crude hydroalcoholic extract of cladodes showed 98.7 % of inhibition of larval development at 12.5 mg/ mL while the crude hydroalcoholic extract of fruits showed 100% at 50 mg/mL, respectively with an LD 50 of 3.4 mg/mL and 3.7 mg/mL (p < 0.05). In the LMIA, crude extracts showed results greater than 65% inhibition of larval migration at 1.56 mg/mL revealing LD 50 of 0.35 mg/mL and 0.76 mg/mL for the extract of fruit and cladodes, respectively. Fractionation of the crude hydroalcoholic extracts of fruits and cladodes yielded four fractions. Among the fractionated extracts, the residual aqueous and in ethyl acetate extracts of cladodes, in the lowest concentration tested (1.56 mg/mL) resulted in 100% inhibition of larval development. The same result was obtained for n-hexane and aqueous extract of fruits. Therefore, the LD 50 for LDA could not be calculated for these extracts. The ... / Mestre

A homoeopathic drug proving of the plant Peucedanum galbanum, analysing symptomatology in relation to the doctrine of signaturesWagner, Abbey January 2007 (has links)
Mini-dissertation submitted in partial compliance with the requirements for the Master's Degree in Technology: Homoeopathy, Durban University of Technology, 2007. / The first objective of this study was to determine the symptomatology that the plant remedy Peucedanum galbanum 30CH, produced in healthy individuals, so that it could be prescribed according to the Law of Similars, as required by homoeopathy. The second objective was to analyse this symptomatology in relation to the doctrine of signatures. It was hypothesised that Peucedanum galbanum 30CH would produce symptomatology in healthy individuals which would correlate to the doctrine of signatures of the plant. / M

A study of the relationship between the natural history of the Solanaceae species and the general and mental symptomatology of the Solanaceae remedies utilised in homoeopathyLong, Bryan Henry January 2011 (has links)
Dissertation submitted in partial compliance with the requirements for the Master‟s Degree in Technology: Homoeopathy, Durban University of Technology, 2011. / Until recently, various attempts have been made to simplify the prescription
process in homoeopathic prescribing. The doctrine of signatures, miasmatic
theory, the homoeopathic repertory and more recently, kingdom analysis by
authors such as Sankaran (1994) and Scholten (1993) are some of the attempts
that have been made to understand the materia medica. With the materia medica
constantly expanding and considering that plants make up a significant
percentage of the materia medica (Kayne, 2006), it is evident that new systems
of homoeopathic prescribing are continually needed to help practitioners both
study the remedies and prescribe more accurately.
Aim
The Solanaceae plant family are an important and well utilised plant family in
homoeopathy (Vermeulen, 2004). Considering this, it was felt that a study
investigating the relationship of the natural history of the family to its general and
mental symptoms be conducted in order to apply a previously unexplored
research paradigm in order to create a greater understanding of Solanaceae
remedies utilised in homoeopathy. The study conducted was a non empirical
correlation study of the Solanaceae plant family‟s natural history and general and
mental symptoms manifested in Solanaceae remedies utilised in homoeopathy.
The aims of the study were to establish if commonalties existed between general
and mental symptoms of individual remedies belonging the Solanaceae family
and their natural histories, as well as to establish if collective commonalities and
correlations existed between the general and mental symptoms and the natural
history of the Solanaceae family as a whole.
Methodology
The homoeopathic remedies obtained from the Solanaceae family of plants for
the study were analysed in terms of rubric representation (size) using
homoeopathic software packages, Radar 10.4 (Archibel, 2009b) and
v
Encyclopedia Homoeopathica (Archibel, 2009a) a sample selection was chosen.
This selection was analysed in terms of general and mental rubrics. Qualitative
thematic analysis was used to establish commonalities in keyword concepts
between the respective natural histories of the studied family and their respective
general and mental symptoms. Keywords obtained from data tables which
included criteria such as habitat and distribution, plant description, active
principles (primary alkaloids), uses, physiological action if ingested, historical
significance, mythology and toxicology were subjected to thesaurus consultation
and tabulated in an attempt to identify synonyms relating to the general and
mental symptoms of individual remedies of the sample group in the study. This
facilitated in the grouping of similar themes. Once commonalities pertaining to
each individual species and remedy was further tabulated and discussed in
terms of keywords relating to their natural histories, a collective analysis of
common correlations between the plant family as a whole was performed.
Results
Common themes related to general and mental symptoms and to the natural
histories of species in the study included “aggression” found in Atropa
belladonna, “depression” found in Solanum dulcamara, “anxiety” found in Datura
stramonium, “confusion” found in Hyoscyamus niger, “burns” found in Capsicum
annuum, “ convulsions” found in Nicotiana tabacum , “ hallucinations” found in
Mandragora officinarum and “delirium” found in Solanum nigrum. Common
themes relating to general and mental symptoms and the natural history of the
Solanaceae plant family as a whole included convulsions, hallucinations,
confusion and anxiety. These themes were further compared to themes exhibited
in Solanaceae studies conducted by Mangialavori (2007) and Sankaran (2002).

Assessment of the antibacterial activity of Artemisia afra, Erythrina lysistemon and Psidium guajavaNsele, Nhlanhla Wiseman 13 November 2013 (has links)
Dissertation submitted in fulfilment for the requirements of the Degree of
Master of Technology in Biomedical Technology, Durban University of Technology, 2012. / Introduction
Medicinal plants have been used for centuries as remedies for human diseases
because they contain components of therapeutic value. Recently, the acceptance of
traditional medicine as an alternative form of health care and the development of
microbial resistance to the available antibiotics have led scientists to investigate the
antimicrobial activity of medicinal plants
Aim
The aim of this study was to investigate the antimicrobial activity of extracts
obtained from medicinal plants used in traditional medicine. A comparative study
was carried out on the antimicrobial properties of extracts obtained by two different
methods in order to choose that which extracts the most effective antimicrobial
compounds.
Methodology
The plants used in this study Artemisia afra, Erythrina lysistemon and Psidium
guajava were harvested from the Silverglen Nature Reserve (Chatsworth) early in the
morning (8 a.m.). The leaves of A. afra and P. guajava extracts and the bark of E.
Lysistemon were used to prepare the extracts. All plant extracts were prepared
according to modified method of the German Homeopathic Pharmacopoea. Two
solvents, water and 60 percent ethanol were used to extract the antibacterial
compounds from plant material.
The extracts were then assessed for their antibacterial activity against Staphylococcus
aureus, Pseudomonas aeruginosa and Escherichia coli. The effect of the plant
extracts on these bacteria was determined by the disk diffusion test, which was used
as the screening test. Positive results were further subjected to the minimum
inhibitory concentration and minimum bactericidal concentration assays. Tubes that
showed no turbidity were then sub-cultured onto non-selective plates. Bacterial
sensitivity testing was carried out in accordance with modified Kirby-Bauer
Antimicrobial Sensitivity Test.
An attempt was made to identify some antibacterial compounds using Thin Layer
Chromatography and High Pressure Liquid Chromatography.
Results
None of the gram negative organisms were inhibited by Artemisia afra, Erythrina
cafra and Psidium guajava. Only the ethanol extracts of all three plants were able to
inhibit Staphylococcus aureus but not Escherichia coli and Pseudomonas
auruginosa. None of the test organisms were inhibited by the aqueous extracts of all
three plants used in this study. In the screening test, the zones of inhibition for
ethanol extracts against Staphylococcus aureus ranged from 3mm – 7mm. The
minimum inhibitory concentration ranged from 16.67 percent – 83.3 percent
inhibition depending on the dilution of the extract.
Quercetin and Catechin were identified as some of the antibacterial compounds
present in the leaves of Psidium guajava. These two compounds were not identified
on Erythrina lysistemon and Artemisia afra.
Conclusion
The results obtained in this study have proven that Artemisia afra, Erythrina cafra
and Psidium guajava ethanol extracts contain antibacterial substances. The ethanol
extracts of all plants in this study inhibited the growth of Staphylococcus aureus but
had no effect on the gram negative bacteria. Aqueous plant did not inhibit the growth
of any bacteria in this study. This study has also shown that antibacterial effect of
these extracts may be considerably enhanced in traditional treatment if traditional
healers can include ethanol as one of the extraction solvents. The results obtained in
this study might be considered sufficient for further studies aimed at isolating and
identifying the active compounds and evaluating possible synergism of antimicrobial
activity among these extracts. Investigations on toxicity of these extracts should also
be carried out.

The formulation, manufacture and evaluation of capsules containing freeze-dried aqueous extracts of Leonotis Leonorus or Mentha Longifolia.Ma, Haiqiu January 2006 (has links)
<p>Leonotis leonorus and Mentha longifolia are two herbs commonly used in South Africa, mostly in oral liquid dosage forms. Several disadvantages are associated with these traditional dosage forms which can perhaps be remedied by using an appropriate oral solid dosage form, provided the actual plant material in the latter still resemble, as closely as possible, the traditionally used material and provide products of suitable pharmaceutical quality. The objectives of this study were to prepare and evaluate the pharmaceutical suitability of the freeze-dried aqueous extracts of Leonotis Leonorus and Mentha Longifolia as plant raw material for the capsule dosage of these two therapies and to formulate and manufacture capsules of Leonotis Leonorus and Mentha Longifolia aqueous extract that would contain amounts of the plant materials equivalent to that found in their traditional liquid dosage forms, and have immediate release characteristics and suitability stability.</p>
