哈士蟆和青蛙输卵管几种主要成分分析测定研究

Study on Nutrient Composition of Oviductus Ranae of Rana Chensinensis and Rana Nigromaculata

分析测定了哈士蟆和青蛙输卵管的蛋白、脂溶性维生素、脂肪酸、微量元素及重金属的成分和含量.结果表明:哈士蟆与青蛙输卵管蛋白含量较高,分别为72.8%和73.8%;哈士蟆输卵管维生素A和维生素D的含量为青蛙输卵管的1.3和1.6倍,哈士蟆输卵管维生素E的含量为4.09μg/g,在青蛙输卵管中未测出维生素E;哈士蟆与青蛙输卵管脂类物质的含量基本上一致,约为6%,其中不饱和脂肪酸含量分别占其脂肪酸的77.26%和64.67%;哈士蟆与青蛙输卵管均含有人体营养必需的常用微量元素,但青蛙输卵管中重金属Pb、Hg含量超标.

The content of the main nutrient compositions, including the crude proteins, the fatty acids, the vitamins, the trace elements, of the oviducts ranae from Rana temporaria chensinensis and Rana nigromaculata was assayed. The result is that both of them contain abundant proteins, some vitamins, unsaturated fatty and some common trace elements, which are useful to human health. There are the more heavy metal Pb and Hg in Oviducts ranae of Rana nigromaculata than the standard.
