Abstract
The hexane soluble part of Isodon ramosissimus Hook has been analyzed by GC and GC-MS. Twelve volatile components were identified. They include: palmitic acid (17.6 %), stearic acid (6,1 %), (2E,4E,6E)-deca-2,4,6-trienal (1.5 %), 2-((E)-prop-1-enyloxy)-6,10-dimethyltridecane (2.0 %), methyl 14-methylpentadecanoate (7.9 %), diethyl phthalate (1.0 %), (E)-methyl octadec-7-enoate (3.0 %), methyl 16-methylheptadecanoate (3.4 %), (9E,11E)-(E)-3-hydroxyprop-1-enyl tetradeca-9,11-dienoate (6.1 %), (3E,5E)-7-((2E,4E,8E,12E)-2,6,10,15-tetramethylhexadeca-2,4,8,12,14-pentaenyloxy)hepta-3,5-dien-2-one (20.3 %), ethyl stearate (2.3 %) and bis (6-methylheptyl) phthalate (2.5 %). The hexane soluble part showed slight in vitro antifungal activity against Microsporum canis and Fusarium solani
