千斤拔挥发性成分的研究

Study on the chemical constituents of volatile oil from Radix Flemingiae Philippinensis

目的 :研究千斤拔中的挥发性成分。方法 :利用水蒸气蒸馏法提取千斤拔 (RadixFlemingiaephilippinensis)挥发油 ,用GC MS进行测定 ,结合计算机检索技术对分离的化合物进行结构鉴定 ,应用色谱峰面积归一化法计算各成分的相对百分含量。结果 :鉴定出 3 9个化学成分 ,其中相对百分率含量大于 4%的分别确定为α 雪松烯 ( 1) ,γ 雪松烯 ( 2 ) ,β 雪松烯 ( 3 ) ,β 愈创烯 ( 4) ,Italicene( 5 )。 结论 :千斤拔挥发油中近 80

Objective: To study the chemical constituents of volatile oil from Radix Flemingiae philippinensis. Methods: The oil was obtained by steam distillation. The chemical compositions were separated and identified by GC/MS. The relative contents in the oil were determined by area normalization method. Results: Thirty-nine compounds were gotten from Radix Flemingiae philippinensis. The compounds of its relative content that was more than 4% were as follows: α-himachalene (1), γ-himachalene (2), β-himachalene (3), β-guaiene (4), Italicene (5). Conclusion: Volatile oil by steam distillation from Radix Flemingiae Philippinensis was separated and ideutified up to 80 percent in component analysis.
