【摘要】 目的:研究葛根素的溶解性及高分子聚合物的助溶作用。方法:利用紫外分光光度法研究PVA、PVP、CMC-Na、MC和HPCM对葛根素的助溶作用。结果:葛根素在水中的溶解度为0.462g/100ml;在4.3％PVP水溶液中葛根素溶解度达1.332g/100ml。结论:在五种常用的药用高分子聚合物中,对葛根素的助溶作用以PVP效果最佳。更多还原

【Abstract】 To study on the solubility of puerarin and the solubilizing effect of ploymer, the solubilizing effects of PVP,PVA, CMCNa.HPMC and MC on Puerarin were studied with ultraviolet spectrophotometry. The solubility of Puerarin in water is 0. 642g/100ml. the best concentration of PVP was 4. 3 per cent,and the solubility of Puerarin increased by 1. 332g/100ml. The solubilizing effects of PVP were the best in these ploymers.更多还原
