Constituents of essential oils from Illicium micranthum Dunn and Illicium griffithii Hook. f. et Thoms

Abstract

The chemical composition of volatiles from the fruit of Illicium micranthun Dunn and the root of Illicium griffithii Hook. f. et Thoms have been studied. The essential oils were obtained by hydrodistillation and analyzed by GC (FID) and GC-MS. The components were identified by MS libraries and their LRIs. The essential oil content was 0.12% (v/w) for I. micranthun, as well as 0.12% (v/w) and 0.15% (v/w), respectively I. griffithii from Pu Mat National Park, Nghệ An Province and Tam Đảo National Park, Vinh Phuc Province, calculated on a dry weight basis. (E)-Nerolidol (18.4%) and linalool (11.0%) are the quantitatively significant compounds of the oil of I. micranthun. The main compounds of Sa Pa I. griffithii oil sample were α-cadinol (24.1%), ι-muurolol (9.8%), α-curcumene (6.9%), aromadendrene (6.8%) and cuparene (6.7%) while borneol (18.8%) and 1,8-cineole (13.2%) occurred in higher quantity in Tam Đảo National Park I. griffithii oil sample. The chemical composition of I. micranthun fruit and I. griffithii root essential oils are being reported for the first time.
