RESUMEN
OBJECTIVE:To find the optimal extraction method for Danshen granules METHODS:According to the orthogonal design L9(34),four factors in extraction were optimized,i e soak duration,decocting times,decocting duration and amount of water added The content of salvianolic acid and the weight of solids were taken as indices RESULTS:The best extracting condition was that 20 mesh size of particles was soaked in eight times amount of water for 1 5h,decocted for 1 5h at first,and then six times amount of water for 1 0h CONCLUSION:This technique is highly repeatable in pilot-experiment
