顶空固相微萃取-气相色谱-质谱联用分析刺山柑不同药用部位挥发性成分

Analysis of Volatile Components in Different Parts of Capparis spinosa L. by HS-SPME-GC-MS

探讨维吾尔族传统药用植物刺山柑不同部位挥发性成分的质量差异,利用顶空固相微萃取-气相色谱-质谱联用(HS-SPME-GC-MS)技术分析,结果从根皮中一共鉴定出47种成分,从近成熟果实中鉴定出46种成分。刺山柑果实和根皮普遍含有较高比例的异硫氰酸类成分,且有一定规律变化,近成熟果实中含有特征性的异硫氰酸乙酯、异硫氰酸仲丁酯,而根皮中主要为较高比例的异硫氰酸甲酯和异硫氰酸异丁酯。本研究报道了刺山柑不同部位的挥发性化学成分,为刺山柑的合理开发提供科学依据。

The volatile components in different parts of the uygur traditional medicinal plants Capparis spinosa L. were investigated. A solid phase micro-extraction（SPME） followed by gas chromatography-mass spectrometry（HSSPME-GC-MS） method was used. Forty-seven compounds were identified from the root bark and 46 components were identified in the nearly ripe fruits. The contents of isothiocyanate compounds in C. spinosa L. fruit and root bark were relatively high with some regularity. Ethyl isothiocyanate and sec-butyl isothiocyanate were specific components in the nearly ripe fruits, while methyl isothiocyanate and isobutyl isothiocyanate had relatively higher proportions in the root bark. Our work reported the volatile components in different parts of C. spinosa L., providing a basis for reasonable development of C. spinosa L..
