鄂西高产半夏脂溶性成分的GC-MS分析

目的:研究鄂西高产半夏中的化学成分。方法:采用气相色谱-质谱联用技术(GC-MS),结合检索NIST谱,鉴定化学成分。结果:从半夏中鉴定出了10个化合物:棕榈酸(palmitic acid)(Ⅰ),十八碳-9,12-二烯酸(9,12-octadecadienoic acid)(Ⅱ),1-吡咯烷-1-氧代-十六碳-7,10-二烯酯(pyrrolidine,1-(1-oxo-7,10-hexadecadienyl)(Ⅲ),α-棕榈精(α-monpalmitin)(Ⅳ),十九碳-1,3,12-三烯烷(1,3,12-nonadecatriene)(Ⅴ),芸苔甾醇(campesterol)(Ⅵ),3-羟基-5,22-二烯-豆甾醇(stigmasta-5,22-dien-3-ol)(Ⅶ),β-谷甾醇(β-sitosterol)(Ⅷ),3-羟基-5,24-二烯-豆甾醇(stigmasta-5,24-dien-3-ol)(Ⅸ),环阿尔廷醇(Cycloartenol)(Ⅹ)。结论:其中5种甾醇类化合物的相对含量:芸苔甾醇28.96%;3-羟基-5,22-二烯-豆甾醇9.24%;β-谷甾醇50.77%;3-羟基-5,24-二烯-豆甾醇4.74%;环阿尔廷醇6.25%。化合物Ⅱ、Ⅲ、Ⅴ、Ⅵ、Ⅶ、Ⅸ为从该植物中首次报道。

Analysis of Lipid Compounds of High-yielded Rhizoma Pinelliae Growing in the West of Hubei Province by Gas Chromatography-mass Spectrometry

OBJECTIVE: To investigate lipid components of high-yielded Pinellia ternata rhizomes growing in the west of Hubei province. METHODS: To determine the lipid chemical components in Pinellia ternata rhizomes with GC-MS method and NIST atlas. RESULTS: Ten components have been found: palmitic acid (I), 9,12-octadecadienoic acid (II), pyrrolidine,1-(1-oxo-7,10-hexadecadienyl) (III), alpha-monpalmitin (IV), 1,3,12-nonadecatriene (V), campesterol (VI), stigmasta-5,22-dien-3-ol (VII), beta-sitosterol (VIII), stigmasta-5,24-dien-3-ol (IX), cycloartenol (X). CONCLUSION: The relative contents of five kinds of phytosterol: campesterol 28.96%, stigmasta-5,22-dien-3-ol 9.24%, beta-sitosterol 50.77%, stigmasta-5,24-dien-3-ol 4.74%, cycloartenol 6.25%. Component II, III, V, VI, IX are the first time reported in Pinellia ternata.
