Study on the Quality Standard of Anshen Jiannao Mixture / 中国中医药信息杂志

ABSTRACT

Objective To study the quality standard of Anshen Jiannao Mixture. Methods Radix ophiopgonis, Radix et Rhizoma Salviae Miltiorrhizae, Fructus Lycii and Radix et Rhizoma Ginseng were identified by TLC. HPLC was used to determine the content of Schizandrol A on C18 (250 mm?4.6 mm, 5 ?m) ODS column. The mobile phase was consisted of methanol-water (55∶45). The flow rate was 1.0 mL/min. The detection wavelength was at 250 nm. Results The characteristic spot of Radix et Rhizoma Salviae Miltiorrhizae, Fructus Lycii and Radix et Rhizoma Ginseng could be easily examined by TLC. The calibration curve of Schizandrol A was linear in the range of 0.121 8～1.218 ?g, r=0.999 9. The precision RSD was 0.22% (n=6). The reproducibility RSD was 1.1% (n=6). The average recovery rate of Schizandrol A was 97.34% (RSD=1.7%, n =6). Conclusions The method is easy, sensitive and specific with good reproducibility. It can be used to control the quality of Anshen Jiannao Mixture.
