Dear Dr-Yasser
I propose you a good method, use an amount from your plant (it's better to let it dry a long time to eliminate the chlorophyll) put it in erlen then add methanol and put it in the ultrasound for 2 hours
I tried this method and a get a good results (4times more then the traditional extraction method)
