岩败酱挥发油化学成分的研究

Studies on the Chemical Constituents of Essential Oil from Roots and Rhizomes of Patrinia rupestris

目的:对败酱科植物岩败酱根及根茎中的挥发油化学成分进行研究。方法:采用水蒸汽蒸馏法提取挥发油。以气-质联用对化学组分进行分离和鉴定,通过标准图谱对照确定化合物名称。以气相色谱归一化法测定其百分含量。结果:鉴定了17个化合物,其含量占挥发油的74.57％。结论:主成分为反式-石竹烯(38.41％),其它尚含α-古芸烯、石竹烯氧化物、蛇麻烯、9,12-十八碳二烯酸等。

Objective: To study the chemical constituents of the essential oil from the roots and rhizomes of Patrinia rupestris. Method: The essential oil was extracted by steam distillation. The components were separated and identified by gas chromatography mass spectrometry and elucidated on the standard mass spectral data. Gas chromatography showed their percentages by area normalization method. Results; Seventeen constituents were identified which make up 74.57% of the oil. Conclusion; Trans-caryophyllene (38.41%) was the main constituent, and other constituents include α-gurjunene, caryophyllene oxide, humulene, 9,12-octadecadienoic acid, etc.
