Abstract:Clearly understand the effect of fall fat， antioxidant effect of the lotus leaf. We have retrieved and consulted literatures in containing lotus leaf experiments in recent ten years at home and abroad. Two aspects have been reviewed： the effects of fall fat and antioxidant of lotus leaf from different active ingredients； the ef－ fects of fall fat and antioxidant from different extraction. Both alkaloids and flavonoids of lotus leaf have the ef－ fect of fall fat and antioxidant， but the main effect of the alkaloid and flavonoids is different， lipid-lowering ef－ fect of alkaloids is strong， and the antioxidant effect of flavonoids is strong. The extraction rate of flavonoids is high by using alcohol/water solvent heating reflux extraction from lotus leaf， and the antioxidant effect of lotus leaf extracts is strong； the fall fat effect of alkaloids is strong by reflux extraction with adding acid from lotus leaf. Attention should be paid to their main medical care source of the active ingredients of lotus leaf.
