摘要
为了充分利用林蛙输卵管特殊的药理活性和林蛙等水陆两栖动物的资源,通过对蛙肉、蛙皮、卵、输卵管、蛙肉、有卵有输卵管的蛙、有卵无输卵管的蛙、无输卵管和无卵的蛙、商品哈什蚂油的氨基酸和脂肪酸含量进行了检测,可根据林蛙不同部分的营养价值而选择不同的部位进行食用。研究发现:哈什蚂油中亮氨酸含量为15.69g/100g、赖氨酸7.20g/100g。蛙肉中赖氨酸为7.20g/100g、色氨酸为90.5mg/100g。不饱和脂肪酸含量为蛙卵124.36mg/g、整蛙79.8mg/g。二十碳五稀酸(EPA,C20:5)和二十二碳六稀酸(DHA,C22:6)总量为蛙卵12.41mg/g为最高,整蛙7.2mg/g,哈什蚂油0.37mg/g,为最低。聚类分析显示:氨基酸含量上有卵蛙和蛙、蛙卵和蛙肉、整蛙和哈什蚂油最近,蛙皮是主效成分。脂肪酸含量上,输卵管和蛤什蟆油、有卵蛙和蛙最近,蛙肉是主效成分。
In order to make use of nutritive value of Rana chensinensis, the study determined contents of amino acids and fatty acids in frog meat, The results showed that leucine is 15.69g/100g, and lysine is 7.20 g/100g in uterine tube of Rana chensinensis. Lysine is 7.20 g/100g, and tyrosine is 90.5 mg/100g in frog meat. The contents of unsaturated fatty acids is 124.36 mg/g in frog eggs and 79.8 mg/g in frog. The contents of timnodonic acids and docosahexenoic acids is 12.41 mg/g in frog eggs, and is 7.2 mg/g in frog. The results of hierarchical cluster analysis showed that the distribution of the amino acids were similar between the ovigerous frog and frog, frog eggs and frog meat, whole frog and uterine tube of Rana chensinensis. The principal component is frog skin in the contents of amino acids. The principal component is frog meat in the contents of fatty acids.
