摘要
对云南省蒙自市引种紫锥菊不同器官的挥发性成分及相对含量进行比较分析,以期为今后资源利用提供参考。采用气质联用(GC-MS)技术结合顶空固相微萃取(HS-SPME)对紫锥菊各器官中的挥发性成分进行分析鉴定。在根、茎、叶、头状花序、花序梗中共鉴定出化合物92种,鉴定出成分的相对含量依次占总挥发性成分的90.034%、90.143%、91.411%、94.279%和89.016%。各器官中挥发性成分以萜烯类、醇类、醛类、酮类、稠环芳香烃类和烷烃类为主。根、茎、叶、头状花序、花序梗中萜烯类成分的相对含量最高,依次分别为66.216%、69.396%、63.818%、58.93%、40.62%;且各器官萜烯类成分的组成不同,根、茎中的萜烯类成分以1-十八烷烯最高,其次是β-石竹烯;叶中萜烯类成分以大根香叶烯D最高,其次为石竹素;头状花序中萜烯类成分以石竹素最高,其次是α-律草烯;花序梗中萜烯类成分以石竹素最高,其次为大根香叶烯D。鉴定出的挥发性成分部分具有抑菌、抗炎、抗癌等药理作用,对人体发育和心脑血管保健有积极作用。研究结果可为引种紫锥菊的药材品质评价和产品开发提供参考。
The volatile components and relative contents in different organs of Echinacea purpurea,introduced in Mengzi City,Yunnan Province,were analyzed through experiments,providing experimental data for their comprehensive development and utilization.The volatile components in the organs of E.purpurea were identified by gas chromatography-mass spectrometry(GC-MS)combined with headspace solid-phase microextraction(HS-SPME).The compositions of 92 compounds were identified in total.The identified components in roots,stems,leaves,capitulum and peduncles accounted for 90.034%,90.143%,91.411%,94.279%,and 89.016%of their total volatile components,respectively,mainly terpenes,alcohols,ketones,polycyclic aromatic hydrocarbons,alkanes and aldehydes.The relative content of terpenes was the highest in the roots,stems,leaves,capitulum,and peduncles,with percentages of 66.216%,69.396%,63.818%,58.93%,and 40.62%respectively.The composition of terpenes in different organs was different.The highest terpenes in roots and stems were 1-octadecenyl followed byβ-caryophyllene.The highest terpenes in leaves was germacrene D,followed by caryophyllin.The highest terpenes in capitulum was caryophyllin,followed by a-cyclohexene.The highest terpenes in peduncles was caryophyllin,followed by germacrene D.Some of the volatile components identified in this study have antibacterial,anti-inflammatory and anti-cancer pharmacological effects,and some have positive effects on human development and cardiovascular and cerebrovascular health care.The research results provide a reference for the quality evaluation and product development of E.purpurea.
