不同产地延胡索挥发油成分分析

[目的]研究陕西和江苏产延胡索药材中挥发油成分的组成及差异。[方法]采用水蒸气蒸馏法提取不同产地延胡索药材中挥发油成分,用GC-MS法进行分析和鉴定。[结果]从陕西和江苏产药材挥发油中分别鉴定出35种和30种化合物,各占延胡索挥发油总峰面积的70.57%和66.41%。其中,共有30种化合物相同,其中含量较高的物质有丹皮酚（24.52%1、8.43%）、棕榈酸（5.35%、6.39%）、2-β-甲氧基-5-α-胆甾烷酸（7.37%5、.76%）等。[结论]产地是影响延胡索挥发油的种类及含量不同的一个因素,这为不同地区延胡索的质量控制提供了参考。

Analysis on Volatile Constituents of RHIZOMA CORYDALIS from Different Places

[Objective] To study the components and their difference of the volatile oil of RHIZOMA CORYDALIS from Shaanxi and Jiangsu Province.[Method] The volatile oil of RHIZOMA CORYDALIS from different producing area was extracted by steam distillation,and its chemical compositions were detected by gas chromatograph-mass spectrometer(GC-MS).[Result] 35 and 30 compositions were respectively identified from the RHIZOMA CORYDALIS from Shaanxi and Jiangsu Province,accounting for 70.57% and 66.41% of the total volatile oil,the RHIZOMA CORYDALIS from those two provinces shared 30 same components,and the components with high content were paeonolum(24.52% and 18.43%),n-hexadecanoic acid(5.35% and 6.39%) and 2,beta-methoxy-5-alpha-cholestan-19-oic acid(7.37% and 5.76%).[Conclusion]The types and contents of chemical components of volatile oil in RHIZOMA CORYDALIS were effected by producing area,which provided references for the quality control of RHIZOMA CORYDALIS in different producing areas.
