More Information
Summary:The invention discloses an extraction method of gastrodin extract. The method comprises the following steps: crushing and sieving a gastrodia elata medicinal material without insects, impurities or decay, adding an ethanol solution into the gastrodia elata powder, performing soaking after uniform mixing, sequentially performing microwave extraction, ultrasonic extraction and filtration, adding filter residues into the ethanol solution to be soaked, repeating the extraction operation twice, combining three filtrates to obtain an extracting solution, performing standing, removing supernate, and carrying out rotary evaporation, vacuum concentration and drying to obtain the gastrodin extract. According to the method, the effective component gastrodin of the gastrodia elata can be effectively extracted, the extraction rate of the gastrodin extract is relatively high and reaches up to 88%, the extraction time is short, the organic solvent can be recycled through the processes of later evaporation, concentration and
