摘要

该文以宁夏、新疆、青海、内蒙古4个产地枸杞为研究对象,对其理化指标、活性物质含量及风味化合物进行测定,以期为枸杞品质评价及产地鉴别提供参考。结果表明,不同产地枸杞理化指标存在一定差异,宁夏及青海产区枸杞生物活性物质含量处于较高水平。气相离子色谱结合偏最小二乘法判别分析结果表明,四产地枸杞大多数挥发性有机物种类相同,但有16种物质在地区之间有较大的含量差异。正丙醇为内蒙古地区枸杞的特有物质,可用于鉴别内蒙古枸杞。糠醛、1-辛烯-3-醇、叶醇、2-甲基丁醛及异戊醛作为通过变量投影重要性值分析筛选出的标记性物质可以对枸杞产地进行初步区分。

Abstract

Wolfberry is a kind of raw material in traditional Chinese medicine. Its quality is related to the producing area. In order to provide a reference for the quality evaluation of wolfberry and identification of their origin,4 kinds of wolfberry from different production areas (Ningxia, Xinjiang, Qinghai and Inner Mongolia) were analyzed in the physio-chemical index, active substance and volatile flavor compounds. The results showed that there were certain differences in the physio-chemical index of wolfberry between different regions and the content of active substances in wolfberry of Ningxia and Qinghai production area showed a high level. The detection of headspace-gas chromatography-ion mobility spectroscopy combined with partial least squares discrimination analysis showed that 16 kinds of substances had significant content differences between producing areas. 1-propanol was a unique substance of the Inner Mongolia area which could be used to identify Inner Mongolia wolfberry. Furfural, 1-octene-3-ol, cis-3-hexen-1-ol, 2-methyl butanal and methyl butyrate selected by variable importance in projection value could be used as marker to distinguish the origin of wolfberry.

Key words： wolfberry; active substances; headspace-gas chromatography-ion mobility spectroscopy (HS-GC-IMS); volatiles markers; partial least squares discrimination analysis
