Copyright policy )[Extraction of ecdysterone from Stemmacantha uniflora].
To optimize the conditions for the extraction of ecdysterone from Stemmacantha uniflora.Conditions for the extraction were studied by three different methods as guided by the content of ecdysterone and solid material that present in the extract.Methanol was the best solvent, water the second, ethanol was greatly effected by concentration. Ultrasonic extraction had a good efficiency with short time. The time of cool extraction was too long, its efficiency was inferior to the other methods.The best methods for the extraction of ecdysterone from Stemmacantha uniflora was methanol reflux extraction.
