Abstract:
【Objective】To optimize the process conditions for active compounds of Flos Datura by microwave-assisted extraction.【Methods】Uniform design was used to observe the effects of microwave power,microwave radiation time,solvent volume,soaking time and extracting time on the extraction of dry extract,total alkaloids,scopolamine of Flos Datura.The contents of total alkaloids and scopolamine of Flos Datura were determined by acid stain colorimetry and HPLC,and the obtaining rate of dry extract was measured by weight method.【Results】 The optimal process conditions for Flos Datura were as follows: soaking the medicinal material for 2 hours with 10 times of 75% alcohol,with continuous radiation for 25 min at the power of 730 W,at 65℃.【Conclusion】Microwave-assisted extraction is superior to soaking extraction method in increasing productivity and economizing the solvent.
