摘    要:为探明3种中药材籽油的开发利用价值,对用索氏法提取的木瓜、火棘和麦冬等3种中药材籽油进行了脂肪酸组成及相对含量的气相色谱分析和维生素E的高效液相色谱含量测定,比较了索氏法与玲浸法提取麦冬籽油成分效率差异.结果表明:3种中草药籽油主要脂肪酸成分是油酸、亚油酸及软脂酸,几乎不含亚麻酸;维生素E则以火棘中含量最高,达300mg/100g(油),麦冬籽油很低,仅0.18mg/100g(种子);索氏法与冷浸法提取麦冬籽油不仅提油效率有明显差异,而且油中的维生素E及脂肪酸组分相对含量(尤其是软脂酸)也明显受到不同提取方法的影响。

关 键 词:木瓜  火棘  麦冬  籽油  脂肪酸  维生素E

Abstract:By application of GC and HPLC,the components of the fatty acid and vitamin E content in the seed oils of three Chinese traditional herbs and the efficiency of Soxhlet-extraction and solvent-extraction were determined.The main components of the fatty acids in the seed oils of three Chinese traditional herbs were oleic acid,linoleate and palmitic acid,with trace linoenic acid.Among the three herbs,Phracantha fortuneana seeds had the highest level of vitamin E (300 mg/100 g oil),while Ophiopogon japonicus seeds had the lowest level (0.18 mg/100g dry seed).At room temperature,soxhlet-extraction and solvent-extraction resulted in significant differences in extraction efficiency and vitamin E and fatty acid contents (especially palmitic acid) in Ophiopogon japonicus seed oils.
Keywords:Cheanomeles speciosa  Phracantha fortuneana  Ophiopogon japonicus (thurb  )  seed oils  fatty acid  vitamin E
