Comparative Study of Volatile Compounds in Different Parts of Albiziajul Ibrissin Durazz / 中国药师

ABSTRACT

Objective:To compare and analyze the volatile components in different medicinal parts of silktree Albizzia julibrissin and their relative contents .Methods:Chromatography-mass spectrometry using headspace solid phase microextraction combined with gas method ( HS-SPME-GC-MS) was used to analyze the volatile components in the bark and flowers of silktree Albizzia julibrissin and the relative contents were calculated by a peak area normalization method .Results:In the bark and flowers of silktree Albizzia julibris-sin, totally 30 and 33 compounds were respectively identified , which respectively accounted for 73.20%and 88.29%of the total vola-tile.A total of 15 components, including alkanes, alkenes, aldehydes, furans, alcohols and acids were in the bark and flowers of silk-tree Albizzia julibrissin, among them, the content of cineole was the highest (bark15.02%and flowers21.9%).Conclusion:The HS-SPME technique can be used to analyze and compare the volatile components in the bark and flowers of silktree Albizzia julibrissin, which provides scientific basis for the reasonable development and application of the bark and flowers of silktree Albizzia julibrissin.
