Extraction methods and bioautography for evaluation of medicinal plant antimicrobial activity

摘要: A comparative study on the antimicrobial properties of extracts from medicinal plants obtained by two different methods was carried out. The screening activity six conducted a disc diffusion test against Gram-positive, -negative and fungal organisms. most active (inhibition diameter ≥12 mm) were assayed for minimum inhibitory concentration submitted to phytochemical thin-layer chromatography bioautography. results indicate that diethyl ether efficient compounds. more pronounced Gram-positive organisms than Gram-negative bacteria. Bioautography showed probably due flavonoids terpenes.
