Chemical analysis and bioassay were used to distinguish quality grades of Salvia miltiorrhiza bge., and the active compounds were investigated on anti-platelet aggregation. We established the HPLC fingerprint of Salvia miltiorrhiza bge. and meansured thir biopotency based on anti-platelet aggregation. The results showed that the HPLC fingerprints of different batches of Salvia miltiorrhiza bge. were similar (Similarity=0.930-0.998), but the difference of biopotency could be ten-fold. Through correlation analysis of chemical fingerprint and anti-platelet aggregation assay, dihydrotanshinone Ⅰ, cryptotanshinone, tanshinone Ⅰ, tanshinone ⅡA, and two unknown compounds were closely related to the biopotency. It was proved that cryptotanshinone was a high activity component on platelet aggregation. To compare the active contribution of the high content Salvianolic acid B and low content of the active ingredient cryptotanshinone, the active contribution value of the two compounds were basically equivalent. Cryptotanshinone, which had low content but high activity, made an important contribution to evaluating the quality of Salvia miltiorrhiza bge.. The results indicated that the quality of traditional Chinese medicine could not be evaluated accurately by only using the chemical content or abundance. This work established a quality evaluation model based on chemical fingerprint and bioassay which could improve the quality evaluation of traditional Chinese medicine associating with effects.
