A Study on the Chemical Components in Essential Oil from Leaves of Cinnamomum kanehirae and Chemotype Divisions
摘要
Abstract
Essential oil from leaves of 5-year old Cinnamomum kanehirae seedlings were extracted by steam distillation method.The chemical components and contents of the essential oil were analyzed by combined gas chromatography⁃mass spectrometry.Based on the first principal component of essential oil the chemotype of the tree was preliminary divided into 4 types:eucalyptol type,iso⁃nerolidol type,linalool type and tetradecanal type.The chemical components and yields of essential oil were significant different from each other.13 specific chemical components were in the essential oil from the leaves of the iso⁃nerolidol type,2 specific chemical components were in the essential oil from the leaves of the eucalyptol type,2 specific chemical components were in the essential oil from the leaves of the linalool type,1 specific chemical component was in the essential oil from the leaves of the tetradecanal type,12 common chemical components were in the essential oil from the leaves of all the 4 types.The average contents of first principal component from the leaves of the 4 types was in the order:linalool type (68.71%),eucalyptol type(57.38%),iso⁃nerolidol type (37.91%),tetradecanal type (33.75%),the average essential oil yields from the leaves of the 4 types was in the order:eucalyptol type (1. 28%),iso⁃nerolidol type (0.19%),linalool type (0.04%),tetradecanal type (0.01%).The chemotypes of the essential oil in the eucalyptol type,the iso⁃nerolidol type and the linalool type of Cinnamomum kanehirae were similar to those of Cinnamomum camphora. With a difference,there was tetradecanal type in Cinnamomum kanehirae,and there were borneol type and camphor type in Cinnamomum camphora.But overall,the essential oil yield of leaves from Cinnamomum kanehirae was lower than that from Cinnamomum camphora.关键词
