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.
目的
研究鄂西地区高产半夏块茎的脂质成分。
方法
采用气相色谱-质谱联用（GC-MS）法和NIST图谱测定半夏块茎中的脂质化学成分。
结果
共发现10种成分：棕榈酸（I）、9,12-十八碳二烯酸（II）、吡咯烷，1-(1-氧代-7,10-十六碳二烯基)（III）、α-单棕榈酸甘油酯（IV）、1,3,12-十九碳三烯（V）、菜油甾醇（VI）、豆甾-5,22-二烯-3-醇（VII）、β-谷甾醇（VIII）、豆甾-5,24-二烯-3-醇（IX）、环阿屯醇（X）。
结论
5种植物甾醇的相对含量分别为：菜油甾醇28.96%、豆甾-5,22-二烯-3-醇9.24%、β-谷甾醇50.77%、豆甾-5,24-二烯-3-醇4.74%、环阿屯醇6.25%。成分II、III、V、VI、IX为首次在半夏中报道。
