目的:建立脾胃舒丸鉴别控制方法。方法:TLC鉴别法。采用硅胶G板,以三氯甲烷-乙酸乙酯-甲醇-水(15:40:22:10)10℃以下放置分层的下层液为展开剂,以10%硫酸乙醇溶液为显色剂鉴别样品中黄芪;分别以乙酸乙酯-甲醇-水(100:17:13)为展开剂,以三氯化铝试液为显色剂,紫外灯(365nm)下检视鉴别样品中陈皮/枳实。结果:样品中所检测的斑点清晰,分离度良好,阴性对照无干扰。结论:建立的TLC鉴别方法灵敏、重现性好,可用于脾胃舒丸质量控制。
Objective: To establish Spleen Wei Stomach pill control method. Method: TLC identification method. Using silica gel G plate, the lower layer liquid was placed under the temperature of 10 ° C. in chloroform-ethyl acetate-methanol-water (15:40:22:10) as developing solvent, and was identified as 10% sulfuric acid in ethanol solution Astragalus membranaceus in the samples were respectively identified by using ethyl acetate-methanol-water (100: 17: 13) as developing solvent, aluminum trichloride solution as a reagent and UV light (365 nm) . Results: Specimens detected in the sample clear, good resolution, negative control without interference. Conclusion: TLC identification established sensitive, reproducible, and can be used for quality control Spleen Wei.
