摘要:

为系统分析不同有机甘薯叶品种的挥发性风味物质组成及其差异,采用顶空固相微萃取(headspace solid-phase microextraction,HS-SPME)结合气相色谱-质谱联用仪(gas chromatography-mass spectrometry,GC-MS)对4种有机甘薯叶的挥发性成分进行分析,以峰面积归一化法计算各挥发物的含量,并结合数学统计学方法对检测到的挥发物进行分析。结果表明,4种样品中共检测出81种挥发性风味物质,包括萜烯类22种、醛类20种、酮类10种、醇类9种、醚类6种和其他类14种,其中共有成分74种,相对含量最高的是萜烯类物质,占挥发物总量的76.50%~86.74%,通过计算相似率可知,4种有机甘薯叶品种间的挥发性成分组成差异性较小。研究结果可为有机甘薯叶的风味研究和加工品的开发利用提供参考。

Abstract:

This study aims to investigate the volatile components of organic sweet potato leaves and analyze the differences in volatile components and their contents among different organic sweet potato leaves. Headspace solid-phase microextraction (HS-SPME) and gas chromatography-mass spectrometry (GC-MS) were used to analyze the volatile components of four types of organic sweet potato leaves. The content of each volatile compound was calculated using the area normalization method, and the detected volatiles were analyzed using mathematical statistical methods. The results indicated that a total of 81 volatile flavor compounds were detected in the four samples, including 22 terpenes, 20 aldehydes, 10 ketones, 9 alcohols, 6 ethers, and 14 others. Among these, 74 components were common to all samples. Terpenes had the highest relative content, accounting for 76.50%-86.74% of the total volatiles. Based on similarity calculations, the volatile compounds of the four organic sweet potato leaves exhibited little difference. The findings of this study provide a reference for flavor research and the development and utilization of processed products from organic sweet potato leaves.

Key words: organic sweet potato leaves, similarity, flavor compounds, headspace solid-phase microextraction (HS-SPME), gas chromatography-mass spectrometry (GC-MS)
