A GC-MS Analysis on Volatile Oil in Wild and Cultivated Disporum cantoniense (Lour.) Merr

Objective:To analyze and compare the differences of volatile oil components extracted from wild and cultivated Disporum cantoniense(Lour.) Merr with GC-MS.Methods:The volatile oil was extracted by steam distillation.The chemical constituents of volatile oil were isolated and detected with GC-MS,and the structures of isolated chemical compounds were identified with computer retrieval.Their relative contents were determined with chromatographic peak area normalization.Results:Forty-eight and 32 chemical compounds were identified in volatilize oil extracted from wild and cultivated Disporum cantoniense(Lour.) Merr respectively.Of them,17 were identical constituents in both of the 2 kinds of volatile oil.Conclusions:The main components in the two kinds of volatile oil are basically the same,but the contents are quite different.It provides a theoretical basis for quality control of cultivated Disporum Cantoniense(Lour.) Merr.
