中药葛根综合开发工艺中试研究

目的对葛根资源综合利用中试工艺进行初步研究,为工业生产打下基础。方法磨浆法制备葛根淀粉,大孔树脂吸附法处理废水制备葛根黄酮,酸水解法制备葛根素。结果100 kg鲜野葛可同时制备18.4 kg纯天然葛粉、205 g精制黄酮(葛根素含量为40.6%)或20 g葛根素(97.6%)。结论本中试工艺有望提高葛根资源的利用率,降低污染排放,增加企业经济效益。

Pilot-scale study on synthetical utilization of radix puerariae

Aim To study the proper pilot-scale process of synthetical utilization of radix puerariae for preparing the starch of radix puerariae,pueraria isoflavones and puerarin.Methods Grinding starch method,absorption with macroporous resin and hydrolyzation with hydrochloric acid were employed for preparing the starch of radix puerariae,pueraria isoflavones and puerarin respectively.Results 18.4 kg starch of radix puerariae and 205 g pueraria isoflavones(40.6 percent of Puerarin) or 20 g puerarin(97.6%) could be prepared by using 100 kg radix puerariae as raw material.Conclusion The process can bring some technical progresses.The most potential value of radix puerariae resource will be exerted,the pollution resulted by producing the starch of radix puerariae will be controlled,and the economic benefit of plant will be improved.
