Cherry leaf cherry (Prunus pseudocerasus Lindl.) Leaves the original plant for the of Rosaceae (Rosaceae) plum genus (Prunus.L) plants . Paper, organic solvent extraction, column chromatography, etc. Methods for the chemical composition of the cherry leaf system separation and purification , to give four compounds manager Constants Determination spectrometry identified the chemical structure of these four compounds , namely : ( 3S, 5R , 6R, 7E, 9R)-megastigmane-7- ene -3,5,6,9 - four alcohol -9 - O - of β- D- glucopyranoside glycoside ( I ) , rutin ( Ⅱ ) , kaempferol - 3-O-α-L- pyran rhamnoside (Ⅲ) and quercetin - 3- O -α - L- pyran rhamnoside (Ⅳ). Ⅰ is a first separation of the compound obtained from the Rosaceae plants , Ⅱ the compound obtained in the first time isolated from cherry leaves .
