目的:建立胃宁散的质量标准。方法:采用HPLC方法对制剂所含橙皮苷进行含量测定。结果:高效液相色谱法(HPLC)测定橙皮苷,可达基线分离,橙皮苷对照品进样量0.1232~0.7392μg内呈线性关系,r=0.9991,平均回收率为99.8%,RSD=1.29%(n=5)。结论:该定量方法快速灵敏,稳定可靠。
Objective: To establish the quality standard of Weiningsan. Methods: HPLC method was used to determine the content of hesperidin contained in the preparation. Results: HPLC determination of hesperidin, up to baseline separation, linear injection of hesperidin in the reference sample amount of 0.1232 ~ 0.7392μg, r = 0.9991, the average recovery was 99.8%, RSD = 1.29% (n=5). Conclusion: The quantitative method is fast, sensitive, stable and reliable.
