目的:探索影响测定健肾片Ⅱ号中黄芪甲苷含量的因素;方法:对样品的提取溶剂、前处理方法及展开剂的选择进行考察;结果:用水提取的供试品中黄芪甲苷含量较用甲醇提取高,氨洗及过大孔树脂柱都有纯化供试品的作用,三氯甲烷-甲醇-10%NaOH水溶液(13:7:2),放置过夜的下层液为最佳展开剂;结论:采用此法测定本品中黄芪甲苷的含量分离效果好,数据稳定可靠。
Objective: To explore the factors influencing the determination of astragaloside IV in Jianzhen Tablets II; Methods: To investigate the extraction solvent, pretreatment method and preparation of the sample; Results: Astragaloside content in the test sample extracted with water Compared with methanol extraction, ammonia washing and macroporous resin columns have the effect of purification of the test sample, chloroform-methanol-10% NaOH aqueous solution (13:7:2), the overnight solution is the best development Agent; Conclusion: This method is used to determine the content of astragaloside IV in this product. The separation effect is good, and the data is stable and reliable.
