Abstract: |
The constituents of volatile oil from the tubers of Siraitia grosvenorii were analyzed by GC MS. About 42 components were separated and 26 compounds were identified,accounting for 83.69% of the total contents. The major components are:2 Butenoic acid,butyl ester(30.76%),2,4 Diacetoxypentane(11.05%),2 Heptanol(10.58%),Acetic acid,butyl ester(4.93%)、1 Hexanol(3.81%),2 butanol acetate(3.05%). |
