摘 要: | 杞菊地黄丸水提取物依次通过强阳离子交换树脂柱、强阴离子交换树脂柱分离得到甜菜碱(Bataine),然后与雷氏盐形成沉淀,沉淀用700g/L丙酮溶解,用比色法在λmax525nm处测定其含量,两个厂家生产的杞菊地黄丸中甜菜碱的含量分别为0.066%,0.074%,平均回收率为97.00%,相对标准差为0.83%,相关系数为0.9998.

Abstract: | The betaine was got from the water extraction of Qijudihuangwan in turn passed through the strong positive and negative ion-exchange resin. After forming the precipitation with ammonium reineckate and dissolving the precipitation with 700 g/L acetone,the content of betaine was deter mined by chromatography colorimetry at λmax525nm. The content of betaine in Qijudihuangwan produced at two factories was 0.066%and 0.074% respectively ,the average rate of recovery was 97.00%,the relative standard deviation was 0.83%and the correlative coefficient was 0.9998. |
