| Abstract: | Objective: To optimize the conditions for the extraction of ecdysterone from Stemmacantha uniflora.Methods: Conditions for the extraction were studied by three differrent methods as guided by the content of ecdysterone and solid material that present in the extract. Results: 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. Conclusion: The best methods for the extraction of ecdysterone from Stemmacantha uniflora was methanol reflux extraction. |
