Antimicrobial and antioxidant activity of two desert truffles, Tirmania and Terfezia

Ali, Saleh A. January 2006 (has links)
Two species of desert truffles, Tirmania and Terfezia were collected from the Northern desert region in Saudi Arabia for antimicrobial and antioxidant activity testing. Both species were extracted with four types of extraction solutions, methanol, ethanol, ethyl acetate and water to test for antimicrobial activity and with three extraction solutions, methanol, ethanol and water for antioxidant activity. Using disc diffusion method, the extracts were subjected to twenty three different microorganisms to observe the antimicrobial activity by measuring clear zones. Methanol extract from Tirmania was the most effective, followed by those extracted with ethanol, water and ethyl acetate respectively. In Terfezia, ethanol extract was better than methanol extract in effectiveness. Ethyl acetate extracts were the least effective. The results indicate that truffles possess antimicrobial activity with broad spectrum effects against Gram positive, Gram negative, aerobic and anaerobic bacteria as well as Saccharomyces, while no effect was recorded with fungi. The results on antioxidant activity showed that truffles have very strong antioxidant property with 99.9% with ethanol extracts of Tirmania species and 95.5% with ethanol extract of Terfezia species using beta-carotene bleaching method and antioxidant property with 96.1% with ethanol extracts of Tirmania species and 95.3% with methanol extract of Terfezia species using DPPH free radical method.

The antimicrobial activity and phytochemistry of african wormwood ( artemisia )

Gwebu, Lehlohonolo, Tebogo 13 June 2003 (has links)
A research report submitted to the Faculty of Health Sciences, University of the Witwatersrand, in partial fulfilment of the requirements for the degree of Science In Medicine ( Pharmaceutical Affairs ) / Artemisia afra Jacq. wild also known as African wormwood, " umhlonyane" ( Xhosa and Zulu ) "lengana" ( Sotho And Tswana ) and "wildeals" ( Afrikaans 0 is an aromatic shrub belonging to the Asteraceace. It is widespread in South Africa extending from the mountainous regions of South Western cape, along the eastern coast to the Northern Province ( van Wyk et. al;1997 ) Due to the popular use of A. afra. The aerial part of sixteen samples from four natural populations were hydrodistilled and the essential oil analysed by GC_MS and tested for antimicrobial activity on anumber of bacteria and fungi. / IT2018

The determination of an extra-skeletal reference line and its reliability

Albert, David M. January 1970 (has links)
Thesis (M.Sc.D.)--Boston University School of Graduate Dentistry. Dept. of Orthodontics. 1970. / The present investigation was undertaken to determine an extra-skeletal reference plane and its reliability. The results of this study revealed that it seems possible for an orthodontist to establish an extra-skeletal reference plane, if a specially designed analyzer is used. It has been shown that by using this devise in his determination of a base landmark, an orthodontist can have a high degree of reliability within himself. It also appears likely that the reference plane obtained in this manner by one orthodontist is reproducible, to a high degree of reliability by other orthodontists. A remarkably high reproducibility, as obtained if a group determination of a reference base was done. To the orthodontist, it means that there may be a way of accurately producing a reliable reference plane for static cephalocentric analysis. This could be used to standardize communication among orthodontists.[TRUNCATED]
