Rosmarinic Acid and Its Methyl Ester as Antimicrobial Components of the Hydromethanolic Extract of Hyptis atrorubens Poit. (Lamiaceae)

Primary biological examination of four extracts of the leaves and stems of Hyptis atrorubens Poit. (Lamiaceae), a plant species used as an antimicrobial agent in Guadeloupe, allowed us to select the hydromethanolic extract of the stems for further studies. It was tested against 46 microorganisms in vitro. It was active against 29 microorganisms. The best antibacterial activity was found against...

Revista Farmacognosia Suplemento 2008.indd

This is the fi rst report about the antibacterial activity of Hyptis martiusii Benth. In this study the ethanol extract of H. martiusii was tested for its antimicrobial activity against strains of Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus. The growth of all bacterial strains tested was inhibited by the extract. The diameter of inhibition zones varied from 13 to 20 mm fo...

Activities of compound G2 isolated from alfalfa roots against dermatophytes.

An antimycotic agent, compound G2, isolated from alfalfa roots exhibited considerable activity against the six most common dermatophytes. MICs in agar and broth dilutions ranged from 10 to 30 micrograms/ml and from 2 to 10 micrograms/ml, respectively. G2 was fungicidal at 5 to 22 micrograms/ml. Structure and toxicity relations are discussed.
