Study on TLC and Content Determination for Xiangshuyin Dispersible Tablets / 中国中医药信息杂志

ABSTRACT

Objective To establish the quality standard for Xiangshuyin Dispersible tablets. Methods Fructus citrus sarcodactylis and Borneolum syntheticum in the prescription were identified by TLC. The content of the total Naringin was determined by HPLC. The column of AichromBond-AQ-C18 (4.6 mm?150 mm,5 ?m) was used. The mobile phase was mobile phase A-mobile phase B (84∶16),mobile phase A was Water-Acetic Acid (100∶1),mobile phase B was Acetonitrile,at the flow rate of 1.0 mL/min,the column temperature of 30 ℃,and peaks were detected at 283 nm. Results The study on the quality control showed that the characteristic of identification by TLC was distinct and highly specific. The linear range of Naringin was 0.120 6～0.603 ?g,r =0.999 9,the average recovery was 97.90%,RSD=1.76% (n=5). Conclusion The method was easy to operate with accurate result and good reproducibility. It can be used effectively for the quality control of the preparation.
