GC-MS分析显脉金花茶脂溶性成分

摘要

Liposoluble components from Camellia euphlebia Merr. Ex Sealy were separated by silica gel column chromatography, and the extracted substances were pretreated by means of methyl esterification and analyzed by GC-MS. 20 of the separated components were identified, amounting for 81%. Organic acids were major chemical constituents,amounting for 35. 99%. Β--Amyrin was the main component,amounting for 17. 24% of the total,followed by palmitic acid (14. 57%) and or Amyrin (13. 6%). These 20 components were first identified from Camellia euphlebia Merr. Ex Sealy.%采用硅胶柱层析提取分离显脉金花茶(Camellia euphlebia Merr.ex Sealy)石油醚部位脂溶性成分,用甲酯化方法对提取物质预处理,用气相色谱-质谱方法分析其化学成分.结果共鉴定出显脉金花茶石油醚部位成分中的20种脂溶性化合物,占总量的81％,主要化学成分是有机酸类,占35.99％,其中β-香树素(17.24％)、棕榈酸(14.57％)、α-香树精(13.6％)含量最高.所得到的20种成分均为首次从显脉金花茶叶中鉴定出来.
