ABSTRACT
Objective To establish a method of the dissolution test of Xinkeshu capsule and study the dissolution behavior of sodium Danshensu, protocatechuic aldehyde, salvianolic acid B and puerarin in Xinkeshu capsule.Methods Using the dissolution determination first law of Chinese Pharmacopoeia 2010 II edition, according to the dissolution test conditions in Japan′s“quality of medical drugs information set”, different Xinkeshu capsule were inspected in pH 1.2 solution,pH 4.0 acetate buffer, pH 6.8 phosphate buffer and water.The HPLC gradient elution method was adopted to determine the dissolution of sodium Danshensu,protocatechuic aldehyde,salvianolic acid B and puerarin in Xinkeshu capsule.ResuIts Dissolution of sodium Danshensu, protocatechuic aldehyde, puerarin and salvianolic acid B of Xinkeshu capsule sample from each manufacturer were in good condition, 45min dissolution were 80% and dissolution uniformity.ConcIusion The method is simple, accurate and reproducible for the dissolution determination of this capsule .
ABSTRACT
Objective To study the effects of Xinkeshu capsule (mainly com po sed of Radix Salviae Miltiorrhizae, Radix Puerariae, Fructus Crataegi, Radix Not oginseng, Radix Auklandiae,etc.) on hemorheology of experimental atherosclerosis rabbits. Methods FASCO- 300 viscosity meter was used to detect whole blood v iscosity and plasma viscosity, hematocrit (Wen's tube) and erythrocyte sedimen tation (Wintrobe tube) were tested, and other items of hemorheology were exami ned. Results Xinkeshu capsule significantly inhibited the abnormal rise of who le blood viscosity, plasma viscosity, whole blood reduced viscosity, erythr ocyte aggregation index, erythrocyte sedimentation (ES), ES rate K, erythro cyte rigid index and Tk in the rabbits with atherosclerosis induced by high fat foodd( P
