摘 要:采用氣相色譜-質(zhì)譜法對寬葉香茶菜石油醚提取物的組成成分進(jìn)行研究。結果表明,從提取物的甲酯化和非甲酯化樣品中共鑒定出65種成分。非甲酯化樣品中鑒定了48種,包括22個(gè)酯類(lèi)、18個(gè)萜類(lèi)及其衍生物、6個(gè)烴類(lèi)和2個(gè)甾體化合物,占出峰面積的77.79%。其中,萜類(lèi)及其衍生物的相對含量總和占流出峰總面積的54.84%,α-香樹(shù)脂酮(18.08%)、γ-Sitostenone(15.89%)、β-香樹(shù)脂酮(15.34%)含量豐富。甲酯化樣品鑒定出17種成分,油酸甲酯、棕櫚酸甲酯的相對含量超過(guò)了15%。所鑒定的化合物均首次從寬葉香茶菜地上部分檢測到,結果為該植物的開(kāi)發(fā)利用提供了科學(xué)依據。 |

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. |
