摘要: 通过单因素试验和正交试验优化顶空-固相微萃取(headspace solid-phase microextraction,HS-SPME)法提取山银花挥发性成分的条件,并采用气相色谱-串联质谱仪和气相色谱-四极杆-飞行时间质谱仪分别对HS-SPME法和水蒸气蒸馏(steam distillation,SD)法的提取物进行分析。结果显示,HS-SPME法的优化条件为萃取温度60 ℃、平衡时间25 min、萃取时间60 min、解吸时间5 min,该条件下鉴定出59 种组分,占总量的97.17%,主要成分为萜烯类、醇类和醛类;SD法的提取物鉴定出68 种组分,占总量的91.69%,主要成分为醇类、醛类和酮类。两种方法提取的挥发油组分种类及含量差异较大。该研究为山银花的质量鉴定和开发利用提供了科学依据。

Abstract: The conditions for extracting volatile components from Flos Lonicerae by headspace solid-phase microextraction (HS-SPME) were optimized by one-factor-at-a-time and orthogonal array design methods. Gas chromatography-mass spectrometry (GC-MS) and gas chromatography-quadrupole time-of-flight mass spectrometry (GC-QTOF MS) were used to detect the extracts obtained by HS-SPME and steam distillation (SD). The results showed that the optimum conditions of HS-SPME were as follows: extraction temperature 60 ℃, equilibrium time 25 min, extraction time 60 min, and desorption time 5 min. Under these conditions, 59 components were identified, accounting for 97.17% of the total amount, and the main components extracted by HS-SPME were terpenes, alcohols and aldehydes; a total of 68 components were identified from the SD extract, accounting for 91.69% of the total amount, with alcohols, aldehydes and ketones being dominant. Accordingly, the types and contents of volatile oil components extracted by the two methods were quite different. This study provides a scientific basis for quality identification, development and utilization of Flos Lonicerae.
