Chemical Composition and Antimicrobial Activities of the Essential Oils of Viburnum opulus,Viburnum lantana and Viburnum orientala

摘要

The composition of the essential oils obtained from the air-dried Viburnum opulus and Viburnum lantana were analyzed by GC-MS.40 and 53 Components were identified in the essential oils and the main component of these taxons were phytol and occidenol in the ratios 7.8 and 6.3 % from V.opulus and V.lantana,respectively.The isolated essential oils of V.opulus,V lantana and V.orientala were also tested for antimicrobial activity against the bacteria E.coli,K.pneumoniae,P.aeruginosa,E.faecalis,S.aureus,B.cereus and the fungus C.tropicalis,at maximum essential oil concentrations in hexane of 250,500 and 1000 mu g/mL,respectively,though no activity was observed against all the test microorganisms for V.lantana and V.opulus.However,the essential oil of the V.orientate showed weak antibacterial activity against Gram-positive bacteria.
