摘要： 以栝楼、３ 个石榴品种(三白玉、青皮软籽和甜绿子)和６ 个苦瓜品种(长白、满优青、槟城一号、开化白苦瓜一号、开化白苦瓜二号和青丰)的种子为材料分析其脂质组成和共轭亚麻酸含量.结果表明:所分析的植物种子脂质组成中最主要的为甘油三酯,其质量分数在９２.６％ 到９７.０％ 之间;栝楼籽油主要的脂肪酸为油酸( ２２.６％ ) 、亚油酸( ３２.６％ ) 和石榴酸( ３２.６％ ) ,而总的共轭亚麻酸( conjugatedlinolenic acid , CLNA)质量分数为３６.９％ ;石榴籽中石榴酸质量分数高达７３.４％ ～ ７７.５％ ,总的CLNA质量分数达８３.４％ ～ ８７.９％ ;苦瓜籽α‐桐酸质量分数高达５６.０％ ～ ６３.７％ ,总的CLNA 质量分数达６５.２％ ～ ７１.９％ .研究结果表明这些植物种子富CLNA ,其中栝楼籽和石榴籽中主要的CLNA 为石榴酸,而苦瓜籽中主要的CLNA 为α-桐酸.
Abstract: The objective was to determine the lipid classes and conjugated linolenic acid (CLNA) contents in T richosanthes kirilow ii , pomegranate and bitter melon seed oils from China . Three pomegranate cultivars (Sanbaiyu ,Qingpiruanzi and Tianlüzi)and six bitter melon cultivars (Changbai ,Manyouqing ,Bingchengyihao , Kaihua-１ , Kaihua-２ and Qingfeng) were chosen for analysis . The predominant lipid was triacylglycerol in the analyzed samples ranging from ９２.６％ to ９７.０％ . The major fatty acids were oleic acid (２２.６％ , １８ :１) , linoleic acid ( ３２.６％ , １８ :２n-６) and punicic acid (３２.６％ , c９ , t１１ , c１３-１８ :３) in T . kirilow ii seed oil . The total CLNA was ３６.９％ in T . kirilow ii seed oil . Punicic acid was the most predominant fatty acid , ranging from ７３.４％ to ７７.５％ and the total CLNA ranged from ８３.４％ to ８７.９％ in the seed oils of pomegranate cultivars . The total CLNA ranged from ６５.２％ to ７１.９％ , and α-eleostearic acid ( c９ , t１１ , t１３‐１８ :３ ) was predominant one , account from ５６.０％ to ６３.７％ in bitter melon seed oils . T . kirilow ii , pomegranate and bitter melon were rich in CLNA , however , main CLNA in T . kirilow ii and pomegranate was punicic acid , and one in bitter melon was α‐eleostearic acid . Natural resources containing CLNA , especially edible T . kirilow ii seed , could be a potential dietary source of CLA , following CLNA metabolism .
