Journal ArticleDOI
The role of structure and molecular properties of terpenoids in determining their antimicrobial activity.
TL;DR: The minimum inhibitory concentrations (MIC) of 60 terpenoids against Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus and Candida albicans have been determined.
Journal ArticleDOI
A cross-cultural study: anti-inflammatory activity of Australian and Chinese plants.
TL;DR: In this study, in vitro inhibitory effects of 33 ethanol extracts obtained from 24 plant species (representing 11 different families) on cyclooxygenase-1 (COX-1) showed inhibitory activity against COx-1, which supports their traditional uses.
Journal ArticleDOI
Anti-inflammatory activity of Chinese medicinal vine plants.
TL;DR: Anti-inflammatory activities of ethanol extracts from nine vine plants used in traditional Chinese medicine to treat inflammatory conditions were evaluated against a panel of key enzymes relating to inflammation.
Journal ArticleDOI
An Agar Dilution Method for the Determination of the Minimum Inhibitory Concentration of Essential Oils
TL;DR: A standardized agar dilution MIC method, using 0.5% v/v Tween 20 as a dispersant, which provides a reliable and reproducible technique and is tested against a wide selection of bacteria, moulds and yeast.
Journal ArticleDOI
Gingerol Content of Diploid and Tetraploid Clones of Ginger (Zingiber officinale Roscoe)
TL;DR: This study did not find significant differences in gingerol concentrations between the tetraploid clones and their parent diploid cultivar, confirming that these compounds are not native constituents of fresh ginger.
