Objective: To optimize semi-bionic extraction technology of compound Tianma Gouteng orally disintegrating tablets. Method: With composite score of gastrodin
rhomotoxine
paeoniflorin and ferulic acid extraction amounts as index
L9(34) orthogonal test was adopted to investigate effects of the amount of water
extracting time and temperature on semi-bionic extraction technology.HPLC was used to determine contents of gastrodin
paeoniflorin and ferulic acid
mobile phase were acetonitrile-0.05% phosphoric acid(3:97)
acetonitrile-0.1% phosphoric acid(14:86) and acetonitrile-0.1% phosphoric acid(17:83)
detection wavelength were 220
230 and 316 nm
respectively;The content of rhomotoxine was determined by UV. Result: Optimum extraction technology was as follows:extracted 2 h with 12 times the amount of water at 60 ℃;Total extraction amounts of gastrodin
rhomotoxine
paeoniflorin and ferulic acid in five times the amount of prescriptions medicines were 0.479
1.276
4.802 and 0.061 g
respectively. Conclusion: This optimized extraction process was stable and feasible
which was suitable for industrial production of compound Tianma Gouteng orally disintegrating tablets.
