【摘要】:采用頂空固相微萃取(headspace solid-phase microextraction,HS-SPME)和Tenax TA吸附劑吹掃捕集(purge and trap,PT)提取金佛手肉和皮的香氣,通過氣相色譜-質(zhì)譜分別檢測出44種和45種香氣物質(zhì),結(jié)果顯示采用HS-SPME和PT萃取金佛手香氣物質(zhì)具有良好的互補(bǔ)性。采用HS-SPME萃取金佛手肉和金佛手皮,通過全二維氣相色譜-四極桿質(zhì)譜分別檢測出43種和40種相似度高的香氣物質(zhì)。此外有23種物質(zhì)香氣活力值大于1,結(jié)合偏最小二乘回歸分析得出對金佛手香氣貢獻(xiàn)較大的物質(zhì)是檸檬烯、芳樟醇、α-蒎烯、β-蒎烯、月桂烯、γ-松油烯、異松油烯、辛酸乙酯、香葉醇、檸檬醛和葉醇等。
[Abstract]:Headspace solid phase microextraction (headspace solid-phase microextraction,HS-SPME) and Tenax TA adsorbent (purge and trap,PT) were used to extract the aroma of Phallophora chinensis, and 44 and 45 aroma substances were detected by gas chromatography-mass spectrometry, respectively. The results showed that HS-SPME and PT were complementary to each other. In this paper, HS-SPME was used to extract the flesh and skin of Golden Buddha, and 43 and 40 kinds of aroma substances with high similarity were detected by gas chromatography-quadrupole mass spectrometry (GC-MS). In addition, the aroma activity values of 23 compounds were more than 1. The results of partial least square regression analysis showed that the major components contributing to the aroma of Jinfa were limonene, linalool, 偽 -pinene, 尾 -pinene, lauryl, 緯 -turpentene, isopentene, and so on. Ethyl octanoate, geraniol, citral and leaf alcohol, etc.
