Abstract
The chemical composition of the essential oil from the fruits and leaves of Litsea cubeba (Lour.) Pers. (Lauraceae) growing wild in Baoshan region, Yunnan Province of China was investigated for the first time in 5.36% and 2.16% (w/w) yields, respectively, when analysed by GC and GC/MS. Ten and 25 components were identified in the fruit and leaf oils which constituted 99.15% and 99.4% of the oils. Of the fruit oil, the major components were neral (36.51%), geranial (44.23%), and citronella (8.77%). The major components of the leaf oil were linalool (67.37%), limonene (6.37%), β-bisabolene (6.03%), neral (5.86%), and caryophyllene oxide (3.20%). The analysis of the essential oil obtained from Baoshan revealed a significant abundance of citral and linalool in the fruits and leaves, respectively. This was the first Litsea species to exhibit β-bisabolene as the principal constituent.
