小叶女贞花挥发性成分分析

Analysis of the Essential Oil from Flower of Ligustrum quihoui Carr.

采用水蒸汽蒸馏法,分别以正己烷和乙醚为萃取剂从小叶女贞花中提取挥发性成分,结合气相色谱-质谱(GC-MS)法,运用峰面积归一化法计算各化学成分在挥发油中的相对含量。在正己烷萃取的挥发油中鉴定了45种组分,在乙醚萃取的挥发油中鉴定了58种组分。研究了不同极性溶剂作萃取剂对小叶女贞花挥发性成分的影响。

The essential oil from Ligustrum quihoui Carr.flowers was distilled by water-vapor and extracted using two kinds of solvent,diethylether and n-hexane.Components in the essential oil were analyzed by gas chromatography-mass spectrometry and quantitatively determined by peak area normalization.Forty-five compounds of essential oil were identified when extracting with n-hexane,and fifty-eight were identified when extracting with diethylether.The polarity of solvent extraction and the structure distributing of volatile components was studied.
