Abstract
Constituents of Radix Salviae Miltiorrhizae and its compound tablets, e.g. tanshinone A, cryptotanshinone, protocatechuic aldehyde and danshensu, were determined by TLC-densitometry. Optimum conditions were selected for constituent extraction, separation and determination. The method is accurate, sensitive and reproducible.
