摘要:

采用超声波辅助-乙醚提取法对梁平柚果肉(干燥和未干燥)、外果皮(干燥和未干燥)及花椒进行提取,利用气相色谱-质谱分别测定了5 种样品提取物的组分,结合Kovats保留指数对其主要成分进行定性分析。结果在花椒提取物中鉴定出6 种酰胺类化合物;在梁平柚的4 种样品中,没有检测出酰胺类化合物;通过对鉴定出的化合物的定性分析及查阅相关文献,确定梁平柚中的麻味物质并不是酰胺类化合物,与引起花椒麻味的物质并不相同。

Abstract:

The components of the exocarp and flesh (in fresh and dried forms) of Liangping pomelo and Zanthoxylum
schinifolium fruits were extracted using ultrasonic-assisted ether extraction method and analyzed by gas chromatographymass
spectrometry (GC-MS) combined with the retention indices (RI). The results showed that there were 6 amide
compounds detected in Zanthoxylum schinifolium. Amide compounds were identified in none of the four samples
of Liangping pomelo Through qualitative analysis of the compounds and comparison with relevant literature
data, the numb-taste components of Liangping pomelo were not the amide compounds and different from those of
Zanthoxylum schinifolium.

Key words: Liangpin pomelo, Zanthoxylum schinifolium, gas chromatography-mass spectrometry (GC-MS), retention indices
