摘要: 采用顶空固相微萃取(HS-SPME)与气相色谱-质谱(GC-MS)联用法(HS-SPME-GC-MS)分析桂枝、白芍及其药对的挥发性成分,单因素考察最佳萃取条件,用面积归一化法计算各成分的相对含量,并进行主成分分析(PCA)。结果表明,最佳的萃取条件为取样量0.60 g、萃取温度60 ℃、萃取时间15 min、解析时间3 min。桂枝、白芍及其药对中分别鉴别出47、49、54个成分,相对含量分别为96.91%、90.58%、94.57%。主成分分析显示,桂枝、白芍及其药对的综合得分有明显差异,其中桂枝-白芍药对的综合得分最高。桂枝-白芍药对中的挥发性成分主要来源于桂枝,桂枝、白芍配伍后的挥发性成分与单味药中的挥发性成分存在明显差异且相对含量有较大变化。

Abstract: The volatile components of cassia twig, white peony, and their drug pairs were analyzed using headspace solid-phase microextraction(HS-SPME) combined with gas chromatography-mass spectrometry(GC-MS)(HS-SPME-GC-MS). The optimal extraction conditions were investigated using single factor analysis. The relative content of each component was calculated using the area normalization method, and principal component analysis (PCA) was performed. The results showed that the optimal extraction conditions were the sample size of 0.60 g, extraction temperature of 60 ℃, extraction time of 15 min, and analysis time of 3 min. Cassia twig, white peony, and their drug pairs identified 47, 49, and 54 components, and the relative contents were 96.91%, 90.58%, and 94.57%, respectively. Principal component analysis showed significant differences in the comprehensive scores of cassia twig, white peony, and their drug pairs, with cassia twig and white peony drug pair having the highest comprehensive score. The volatile components in the cassia twig and white peony drug pair mainly came from cassia twig. The volatile components after the combination of cassia twig and white peony were significantly different from those in a single drug, and there was a significant change in relative content.

Key words: cassia twig, white peony, cassia twig and white peony drug pair, volatile components, headspace solid-phase microextraction, gas chromatography-mass spectrometry, HS-SPME-GC-MS
