The Study Of The Exploitation On The Pharmaceutical Plant Resouces In Xinjiang

This paper, based on roots and stems of Glycyrrhiza inflata. in Xinjiang, attempts to extract Glycyrrhiza saponins from it by macro absorption resin. Macro absorption resin is a effective method which extract and separate useful parts in medical plants. The paper choice seven macro absorptive resins and study standard Glycyrrhiza saponins quiet absorptive and dis-absorptive experiment by use of the theories and method of many subjects, such as those of botany, plant chemistry, biology chemistry and medical chemistry. The result show the absorption of D290 and D301 is the best. It is not comform to the paper in which D101 is good. But it can not dis-absorptive by different concentration alcohol. I study dis-absorption. The result show: PH=3 80% alcohol is very good. I choice D290 at last. Though further research, the results show: D290 can absorb 5 double resin volum but it can' t let out and it has 15 double resin volum when it is saturated. When Glycyrrhiza sopanin PH=5, conoentration=5mg/ml, flow rate=4BV/h, its absorption is the biggest. When dis-absorption is 80% PH=3 alcohol, its dis-absorption is very good. The coarse product of Glycyhhriza sopanin is according to rute form Dong A Ling who is my depart graduate student before. Then the coarse product is absorbed by D290 and make exact product. Last, the pure degree is 83.2% through the determine of HPLC. I also test to extract Glycyhrriza sopanin by microwave. The use of time is very little with this method. The extract of Glycyhrriza sopanin with macro absorb resin is very simple. The common laboratory can carry on. I propose that the extract of Glycyhrriza saponin by macro absorb resin can combine with factory so that it can enhance the significance of Glycyhrriza in Xinjiang and prosperous the economic of my district.
