胡椒根油树脂化学成分的研究

The Analysis of Chemical Constituents of the Oleoresin in Roots of Pepper

为了充分利用胡椒根油树脂,采用气相色谱-质谱联用技术(GC-MS)分别对乙醇和乙酸乙酯提取的胡椒根油树脂化学成分进行分析测定,并结合计算机检索技术对其成分进行结构鉴定,应用色谱峰面积归一化法计算各成分的相对百分含量。结果显示,在乙醇和乙酸乙酯提取的胡椒根油树脂中,共鉴定了27种化学组分,分别占相对总量的98.2%和89.95%。其中,这2种胡椒根油树脂中含量较高的成分主要有piperine、1,2-Diheptylcy-clopropene、nonadecatriene、N-isobutyl-4-hexanoyl-4-hydroxy-pyrrolidin-1-one、Octanoic acid6-ethyl-3-octyl ester、caryophyllene、1-[1-oxo-3(3,4-methylenedioxy-5-meth-oxyphenyl)-2Z-propenyl]-piperidine、(±)-erythro-1-(oxo-4,5-dihy-droxy-2E-decaenyl)-piperidine、2-(decahydroisoquinolin-3-yl)-propionic acid ethyl ester。

In order to utilize the oleoresin from the pepper roots, chemical constituents of the pepper roots oleoresin made from alcohol and ethyl acetate were analyzed by using the gas chromatography-mass spectrometry （GC-MC）, and identified by the mass spectra, and their relative percentage was calculated from the GC peak areas. Twenty-seven compounds were identified, accounting for 98.2% and 89.95% of the total detected constituents, respectively. The major constituents identified from the two oleoresin include piperine, 1, 2-Diheptylcy-clopropene, nonadecatriene, N-isobutyl - 4- hexanoyl- 4 -hydroxy-pyrrolidin-l-one, Oetanoic acid 6-ethyl-3-octyl ester, caryophyllene, 1-[1-oxo- 3 （3, 4- methylenedioxy- 5- meth- oxyphenyl） - 2Z-propenyl]-piperidine, （±）-erythro-1-（oxo-4,5-dihy-droxy-2E-decaenyl）-piperidine, 2-（deeahydroisoquinolin-3-yl）-propionic acid ethylester.
