Abstract:
OBJECTIVE: To optimize the extraction conditions of plumula nelumbinis. METHODS: The semi - bionic extraction (SBE) conditions were optimized by homogeneous design while total alkaloids and dry extract were adopted as markers. Factors of extraction time, solute quantity and the pH values were evaluated for their effects on extraction process. RESULTS: Optimal parameters were as follows: plumula nelumbinis was extracted in water 8 times as much as it for 3 times; the pH values of the water for the 1st, 2nd and 3rd decoctions were 5.0,6.0 and 8.0, respectively; the boiling lasted 4 hours. CONCLUSION: The method prouides theoretical reference for the extraction plumula nelumbinis.
