【摘要】：目的:对窄叶鲜卑花果穗的挥发油成分进行研究。方法:采用水蒸气回流法提取窄叶鲜卑花果穗挥发油,通过气相色谱-质谱联用(GS-MS)技术对其挥发油中化学成分进行分析鉴定,并用峰面积归一化法确定各化学成分的相对百分含量。结果:从窄叶鲜卑花果穗中分离鉴定得到50种化合物,占挥发油总量的99.32%,主要成分为:邻苯二甲酸二异辛酯(17.42%)、二十酸乙酯(9.08%)、叶绿醇(6.29%)、山嵛酸乙酯(6.21%)、正三十四烷(5.15%)、植酮(4.69%)、正二十三烷(4.14%)、二十五烷(3.85%)、亚麻酸乙酯(3.76%)、棕榈酸(3.73%)、抗坏血酸二棕榈酸酯(2.59%)、亚油酸乙酯(2.53%)等。结论:窄叶鲜卑花果穗挥发油种类较多,以酯类物质和烷烃类为主。
[Abstract]:Objective: to study the constituents of the volatile oil from the panicle of Xianbei flower with narrow leaf. Methods: the volatile oil was extracted from the ear of Xianbei flower with narrow leaf by the method of water vapor reflux. The chemical constituents of the volatile oil were analyzed and identified by gas chromatography-mass spectrometry (GC-MS). The relative percentage content of each chemical component was determined by the method of peak area normalization. Results: 50 compounds were isolated and identified from the panicle of Flos Xianbei with narrow leaves, accounting for 99.32% of the total volatile oil. The main components are: diisooctyl phthalate 17.42, 20 ethyl ester 9.08, green alcohol 6.29, ethyl ferrate 6.21). 34 alkanes 5.15%, phytosterone 4.69, 23 alkanes 4.14, 25 alkanes 3.85, ethyl linolenic acid 3.76). Palmitic acid 3.73m, ascorbic acid dipalmitate 2.59m, ethyl linoleate 2.53. conclusion: there are many kinds of essential oil in the panicle of Flos pinellifolia. Mainly esters and alkanes.
