ABSTRACT

AIM: To establish the determination of quality standard for Qingyin Injection(Herba Artemisiae Annuae, Flos Lonicerae). METHODS: The contents of chlorogenic acid and camphor in Qingyin Injection were determined by the HPLC and GC, respectively. RESULTS: Chlorogenic acid showed good linear relationship in the range of 0.0476～0.3808?g(r=0.9999). The average recovery was 96.14%,RSD=0.88%(n=6); Camphor showed a good linear relationship at the range of 0.462～2.77?g(r=0.9999). The average recovery was 100.22%, RSD=2.44%(n=6), respectively. CONCLUSION: The method is simple, quick, accurate and reliable, and can be used for the determination of this preparation.
