摘要:

The leaf oil ofCymbopogon distans(Steud.) Wats, chemotype Loharhket and the root oil ofCymbopogon jwarancusa(Jones) Schult. were examined by GC and GC/MS and found to qualitatively exhibit a very similar sesquiterpenoid composition. The sesquiterpenoid content of theC. DistansandC. Jwarancusaoils was 79.6% and 38.0%, respectively. Most of the sesquiterpenoids were isolated by liquid chromatography and their structures assigned on the basis of their IR, MS,1H- and13C-NMR spectra. The main components inC. distansleaf oil were eudesmanediol (34.4%) and 5-epi-7-epi-α-eudesmol (11.2%), while the largest sequiterpenoid component in the root oil ofC. jwarancusawas agarospirol (9.5%).
