大豆粉中家蚕忌避因子的阻食机理及理化性质研究

Inhibiting Mechanism and Physicochemical Properties of Eating Repellent Factor to Silkworm in Soybean Meal

从大豆粉的乙醇抽提物中分离到６ 种组分，其中１ 种（ 编号为ｅ） 是对家蚕摄食抑制作用最强的成分。该提取物通过刺激下颚瘤状体 Ｓ ＳⅡ中的 Ｒ 细胞兴奋而产生阻食作用，而对 Ｓ ＳⅠ无影响。对该提取物的理化性质测定表明，其具有皂甙的一般性质，初步确定是几种大豆皂甙的混合物。

Six ingredients were separated from the extrative components from soybean meal by ethanol.One of them (named e) was the strongest inhibiting ingredient.The electrophysiological responses showed that the ingredient inhibited silkworm from eating by stimulate the R cell of maxilla SS Ⅱ,and no effect on SS Ⅰ.The determined results of the physicochemical properties showed that it had general properties of saponin.And it was thought to be a mixture of some soybean saponins in an tentative idea.
