麻竹笋中多酚类化合物的提取及挥发性成分分析

采用4 种不同溶剂提取麻竹笋中的多酚类化合物，并通过气相色谱-质谱技术对多酚类提取物中的挥发性
成分进行鉴定和定量计算。结果表明：60%甲醇、50%乙醇、30%丙酮、乙酸乙酯4 种不同溶剂提取物中的总酚含
量分别为4.94、4.85、4.47 mg/g和2.22 mg/g。4 种溶剂提取的麻竹笋多酚类化合物中共鉴定出24 种挥发性物质。其
中，含量较高的物质有4-对羟基苯甲醛、4-对羟基苯乙腈、乙酸、1,2,3,5-四羟基环己烷、2,3-二氢-3,5-二羟基-6-甲
基-4-吡喃和丙酮醇等，而提取物中的挥发性酚类物质主要为邻苯二酚和3-甲基邻苯二酚。

Analysis of the Volatile Components in Polyphenol Compounds Extracted from Dendrocalamus latiflorus Shoots

This research was focus on the extraction of polyphenol compounds from Dendrocalamus latiflorus shoots with
four different solvents, and the volatile compounds in polyphenol extracts were identified and quantitatively evaluated
by GC-MS. The results showed that total phenol contents in methanol, ethanol, acetone, and ethyl acetate extracts were
4.94, 4.85, 4.47 and 2.22 mg/g, respectively. Totally 24 volatile compounds were identified from the four polyphenol
extracts. Among them, the most abundant compounds were 4-hydroxybenzaldehyde, 4-hydroxybenzyl cyanide, acetic acid,
1,2,3,5-cyclohexanetetrol, 2,3-dihydro-3,5-dihydroxy-6-methyl-4-pyran and pyruvic alcohol. The major volatile phenols in
the extracts were pyrocatechol and 3-methylcatechol.
