EXTRACTION METHOD OF ANTI-GLYCOSURIA FUNCTIONAL SUBSTANCE USING GASTRODIA ELATA BLUME

摘要

PURPOSE: A method for extracting an anti-diabetic functional material using Gastrodia elata Blume is provided to save labor and energy for hot water extraction and to obtain more active ingredients. CONSTITUTION: A method for extracting an anti-diabetic functional material using Gastrodia elata Blume comprises: a step of removing sand and foreign materials remaining on Gastrodia elata Blume skin by washing three times and pulverizing; a step of culturing yeast; a step of dipping the pulverized Gastrodia elata Blume in yeast culture liquid and fermenting in a fermenting device at 25-36C for 72-240 hours; a step of centrifuging the fermentation liquid and finally removing residue after centrifugation; a step of maturing the Gastrodia elata Blume fermented liquid at 1-10C; a step of HPLC(high performance liquid chromatography) of fermentation liquid; and a step of comparing active ingredients of Gastrodia elata Blume before and after fermentation.
