摘 要:采用气相色谱-质谱法对宽叶香茶菜石油醚提取物的组成成分进行研究。结果表明,从提取物的甲酯化和非甲酯化样品中共鉴定出65种成分。非甲酯化样品中鉴定了48种,包括22个酯类、18个萜类及其衍生物、6个烃类和2个甾体化合物,占出峰面积的77.79%。其中,萜类及其衍生物的相对含量总和占流出峰总面积的54.84%,α-香树脂酮(18.08%)、γ-Sitostenone(15.89%)、β-香树脂酮(15.34%)含量丰富。甲酯化样品鉴定出17种成分,油酸甲酯、棕榈酸甲酯的相对含量超过了15%。所鉴定的化合物均首次从宽叶香茶菜地上部分检测到,结果为该植物的开发利用提供了科学依据。

Abstract:The chemical constituent of petroleum ether extracts from Rabdosia latifolia was analyzed by gas chromatography-mass spectrometry. The results of gas chromatography-mass spectrometry showed that 48 components from the non-methylated samples, including 22 esters, 18 terpenes and their derivatives, 6 hydrocarbons and 2 steroids. Among them, the sum of the relative content of terpenoids and their derivatives accounts for 54.84 % of the total outflow peak area, and the contents of α-amyrone (18.08 %), γ-Sitostenone (15.89 %) and β-amyrone (15.34 %) are abundant. Meanwhile, 17 ingredients were identified from the methylated samples, and the relative content of methyl oleate and methyl palmitate exceeded 15 %. All identified compounds were detected for the first time from Rabdosia latifolia. And the results provide scientific basis for the development and utilization of the plant.
