棉酚存在于棉属植物的根皮和种子中,棉酚在提取、精制和贮存中易带进各种不同的杂质,影响棉酚的纯度。文献所载关于棉酚纯度标准对杂质检查尚缺乏更有效的措施,我们由于研究棉酚用于防治气管炎和男性节育药工作的需要,从1971年起,利用国产吸附剂硅胶,进行了棉酚的薄层层析分析,先后试得五种溶剂系统,能分别适用于棉根皮中色素制备性分离和棉酚、乙酸棉酚的纯度检查。检查纯 Gossypol exists in the root barks and seeds of Gossypium plants. Gossypol is easily introduced into various impurities during extraction, purification, and storage, affecting the purity of gossypol. The standards for gossypol purity contained in the literature still lack more effective measures for impurity inspection. Because of the need to study the use of gossypol in the prevention and treatment of bronchitis and male fertility drugs, since 1971, we have used domestic adsorbent silicone to conduct cotton. Thin-layer chromatography analysis of phenol, in order to obtain five kinds of solvent systems, can be applied to the pigment preparation of cotton root bark separation and gossypol, gossypol acetate purity check. Check pure
