tudies on Chemical Constituents of Volatile Oil from Leaves and Flowers of Michelia alba from Different Provenances
In order to develop and utilize the plant resources of Michelia alba,,he volatile oil from the leaves and flowers of two provenances was extracted by steam distillation technique,and its components and contents were analyzed by GC-MS.The results showed that the yield of essential oil was higher in the leaves than in the leaves,and the components and contents of volatile oil were different in the leaves and flowers of different provenances.40 compounds and 45 compounds were identified from the leaves and flowers in Guangdong,39 and 48 compounds were identified from the leaves and flowers in Guangxi,respectively.Linalool was the most important component in the leaves and flowers in Guangdong and the flowers in Guangxi,accounting for more than 50％.However,alkane was the most important chemical component in the leaves of Guangxi,accounting for 55.15％.The results of principal component analysis showed that the interaction and mutual influence of multiple volatiles.
