摘要：
The volatile components and in vitro antimicrobial activities of Emblica (Phyllanthus emblica L.) essential oils (EOs) obtained by hydrodistillation (HD-EO) and supercritical fluid extraction (SFE-EO) were investigated. The compositions of volatile compounds in these oils were tentatively determined by gas chromatography-mass spectrometry. The antimicrobial activites of these two extracts were investigated with microbiological tests against Gram-positive and Gram-negative bacteria and three pathogenic fungi. The main components of both oils were beta-caryophyllene, beta-bourbonene, 1-octen-3-ol, thymol, and methyleugenol. Both essential oils showed a broad spectrum of antimicrobial activity against all the tested microorganisms. Gram-positive bacteria were more sensitive to the investigated oils than Gram-negative bacteria. SFE-EO exhibited a higher antifungal activity compared to HD-EO.
