摘要
目的:分析黔产无籽刺梨挥发油的化学成分,为其质量评价提供科学依据。方法:采用超临界CO2萃取法提取无籽刺梨挥发油,并通过气相色谱-质谱(GC-MS)联用仪对其化学成分进行分析和鉴定,用色谱峰面积归一化法计算各组分相对含量。结果:从超临界CO2萃取法提取得到的挥发油中分离出39个组分,鉴定了其中33个化合物,已鉴定的组分占挥发油总量的91.48%,主要成分为β-谷甾醇(14.49%)、三十一烷(13.82%)、二十八烷(7.57%)、己酸(6.80%)、11-(戊烷-3-基)二十一烷(6.75%)、四十四烷(6.56%)等,另外还发现了少量的具有多种生物活性的角鲨烯(3.19%)和羽扇豆醇(1.18%)。结论:黔产无籽刺梨挥发油中含有酯、醇、烷烃、甾体等多种化学成分,分析结果为其质量控制提供依据。
Objective： To analyze the chemical constituents of volatile oil from Rosa sterilis by GC-MS. Method： The volatile oil was extracted from R. sterilis by supercritical CO_2 extraction. Its chemical constituents and relative contents were analyzed and identified by GC-MS. Result： Thirty-three compounds were identified, representing 91.48% of the total composition. The main components of the oil were β-sitosterol （14.49%）, hentriacontane （13.82%）, octacosane （7.57%）, hexanoic acid （6.80%）, 11-（pentan-3-yl）henicosane （6.75%）, tetratetracontane （6.56%）. In addition, squalene （3.19%） and lupeol （1.18%） were also detected. Conclusion： The study provide a scientific basis for the further exploitation and utilization of the fruit.
