salvia genus is one of the largest genera of the lamiaceae family. its species have been used for a wide variety of disorders in the local traditional medicine systems. therefore, the genus has been the subject of several phytochemical and biological studies. the aim of the study was to identify the major antioxidant compound(s) from the methanol extract of salvia verticillata using activity-gu...

Objective: The tamoenju (Hibiscus surattensis L.) is one of the plants as traditional medicines to treat infections. Tamoenju leaves contain alkaloids, flavonoids, saponins, tannins, and steroids, a potential antibacterial agent. This study aimed determine activity extract fraction against Staphylococcus aureus (ATCC 25923) Salmonella typhi 14028), detect active compounds using Thin Layer Chrom...

INTRODUCTION In vitro antioxidant and antibacterial activity and volatile compositions of two Heracleum species (Apiaceae) including Heracleum transcaucasicum and Heracleum anisactis roots Essential Oil (EO) were investigated. METHODS The volatile compositions of EOs were analyzed by GC/Mass spectroscopy. To detect the antioxidant activity of essential oils TLC-bioautography and DPPH radical ...

A common screen for plant antimicrobial compounds consists of separating plant extracts by paper or thin-layer chromatography (PC or TLC), exposing the chromatograms to microbial suspensions (e.g. fungi or bacteria in broth or agar), allowing time for the microbes to grow in a humid environment, and visualizing zones with no microbial growth. The effectiveness of this screening method, known as...

Plant extracts have a long history to be used in folk medicine. Cassia alata extracts are known to exert antibacterial activity but details on compounds and mechanism of action remain poorly explored. We purified and concentrated the aqueous leaf extract of C. alata by reverse phase-solid phase extraction and screened the resulting CaRP extract for antimicrobial activity. CaRP extract exhibited...

Interest in the antioxidant activity of bamboo leaves is growing. To discover new sources of natural antioxidants, a TLC bioautography method combined with a new image processing method was developed to evaluate the antioxidant activity of leaf extracts from 15 different species of bamboo. The results showed that the methanolic extract of Bambusa. textilis McClure possessed the highest antioxid...

The anti-bacterial and anti-fungal activity of four aqueous plant extracts (1 x 10 μg/ml) of 2,3'4,5'-tetra hydroxy-4'-geranylstilbene (chlorophorin) and 3',4, 5' trihydroxy 4' geranylstilbene (Iroko) from the tree Chlorophora excelsa and (6aR,11aR)-3-hydroxy-8,9-methylenedioxypterocarpan (Maackiain) and 7-hydroxy4'-methoxyisoflavone (formononetin) from Virgilia oroboides were evaluated by the ...

Johar plant is a type of from the Fabaceae family which widely used in traditional medicine such as malaria, itching and diabetes medicine. This study aims to determine antibacterial activity stem bark extract with different levels solvent polarity on growth Staphylococcus aureus Escherichia coli bacteria active compound class by TLC-Bioautography. The extraction compounds multilevel maceration...
