西藏砂生槐种子营养成份的初步研究

砂生槐(Sophora moorcroftiana)是藏南河谷地带分布极广的一种多年生豆科灌木,具有极强的抗旱、耐瘠、抗风沙等生态适应性。目前当地群众挖其植株作为生活燃料,收其干叶作为牲畜越冬饲料,破坏相当严重。为充分开发其利用价值,首次取其种子进行营养成份分析,发现其富含蛋白质和脂肪17种氨基酸含量达 23％以上除色氨酸未能测定外,其余7种必须氨基酸含量均高于豌豆(Pisum sativrm)热值 4 800千卡/公斤左右。具有较高的饲用或食用开发价值。

A PRELIMINARY STUDY ON THE NUTRITIONAL INGREDIENTS OF SOPPHORA MOORCROFTIANA IN TIBET

Sophora moorcroftiana is a kind of perennial lesume bush, which widely distributes in the Yaluzangbu Valley of southern Tibet. With the stron ecological adoptation of drought-resistance, barrentolerance, wind-resistance and sand-fixation, it plays a very important role in environment protection of the region. But it is destroyed heavily at present as the whole plant is dug for fuels. In order to find a way to explore and utilize its higher economic value, the nutrients of its seed is analysed and the results are as follows:(1)It is in rich protein (30%) and fat (8%).(2)The content of the 17 kinds of amino acids reaches more than 23%.(3)The essential amino acid content in sophora moorcroftiana's seeds is higher than that in pea (pisum sativum).(4)The calorfic value reaches 4 800 kcal/kg.
