气相色谱-质谱法测定艾叶挥发油中化学成分

GC-MS Determination of Components of Volatile Oil in Folia Artemisiae Argyi

摘要: 采用水蒸气蒸馏法提取艾叶的挥发油,用气相色谱-质谱法分离和鉴定挥发油成分,并用归一化法测定其相对含量。共分离出76个组分,鉴定出59种化合物。其含量占总挥发油组分峰面积的94.3%。贵州遵义产艾叶主要挥发油成分及其含量为1,8-桉叶油素(22.19%)、樟脑(10.39%)、绿花白千层醇(6.57%)、蒿醇(4.95%)、L-龙脑(4.88%)、α-松油烯(3.98%)、蒿酮(3.44%)、顺式桧烯水合物(3.36%)、4-松油醇(2.68%)、菊油环酮(2.51%)、β-崖柏酮(2.41%)、1-松油醇(2.32%)和丁香酚(2.26%)等。

Abstract: The sample of folia artemisiae argyi was extracted by steam distillation, components of the volatile essential oil were separated and identified by GC-MS, and their relative contents (in %) were found by the method of normalization. Totally 76 compounds were separated, among which 59 compounds were identified and determined, amounting to 94.3% of the total peak areas of the components of the volatile oil. The main compounds found with their relative contents were as follows: 1,8-cineole (22.19%), camphor (10.39%), viridiflorol (6.57%), artemisia alcohol (4.95%), L-borneol (4.88%), α-terpinolene (3.98%), artemisia ketone (3.44%), (z)-sabinene hydrate (3.36%), 4-terpineol (2.68%), chrysanthenone(2.51%), β-thujone (2.41%), 1-terpineol (2.32%)and eugenol (2.26%).
