| 摘 要： | 豆科植物蛋白中含硫氨基酸尤其是蛋氨酸含量低,影响其蛋白质的营养价值。为开发出更高甲硫氨酸含量蛋白质基因资源,采用酸水解法,对我国亚热带常见的119种森林植物种子的蛋氨酸含量进行了测定。结果表明:93%以上植物种子的蛋氨酸含量较低,只有八仙花、榕叶冬青、山苍子、锌树、龙葵、栾树、商陆和盐肤木的蛋氨酸含量在10.00mg/g以上,其中盐肤木的蛋氨酸含量为119种植物中最高,达36.89mg/g,可以作为进一步开发的新型高蛋氨酸蛋白基因资源。 |

| Abstract: | Low content of the sulfur amino acid especially methionine is responsible for the relatively poor nutritional quality of legume protein.The methionine content in seeds of 119 subtropical plants in our country was determined by acid hydrolysis method.The results showed that more than 93% plants had low methionine contents.However,the methionine content of Hydrangea macrophylla,Ilex ficoidea,Litsea cubeba var.formosana,Catalpa ovata,Solanum nigrum,Koelreuteria paniculata,Phytolacca acinosa and Rhus chinensis was found to exceed 10.00 mg/g,and that of Rhus chinensis was the highest,which reached 36.89 mg/g.The species Rhus chinensis could serve as a new methionine-rich protein gene resource. |
