Objective: To optimize extraction technology of compound Changtai granules for industrial production of this preparation. Method: Orthogonal test was employed to investigate influences of the amount of water
extracting time and decoction times on extraction process by taking contents of ginsenoside Rb1
hederagenin and extract as comprehensive evaluation indexes.Contents of ginsenoside Rb1 and hederagenin were determined by HPLC
mobile phases were consisted of acetonitrile(A)-water(B) for gradient elution(0-5 min
10%-30%A;5-20 min
30%-45%A;20-22 min
45%-10%A) and acetonitrile-0.1% aqueous formic acid(70: 30). Result: Optimum extraction technology was:refluxing extracted 3 times with 10
8
8 times the amount of water with 1 h per time.Under these conditions
contents of ginsenoside Rb1 and hederagenin were 2.48
10.50 mg · g-1
respectively;yield of extract was 16.72%. Conclusion: This optimized extraction technology is feasible
stable and suitable for industrial production of compound Changtai granules.
