Structural Identification Of New Flavones From Leaves Of Prunus Pseudocerasus Lindl

Prunus pseudocerasus Lindl. is widely distributed in theNortheast, Southast and Norht China, which is known as a kind ofwellknown fruits of Prunus genus(Rosaceae). In Prunus genus , thereare about 100 kinds of species over the world and 60 kinds of speciesin China. These days ,chemical constituents and pharmacology ofPrunus genus plants were studied in Chian , America , Germany ,Korea. Flavones, glycoside, terpenoids, amino acids, mineral,steroids, coumarin and etc. were investigated for there structures andactivities. Medicines and health care products have been eveloped toantisepsis, anticancer and curing angiocardiovascular diseases.Prunus pseudocerasus Lindl.has long history in China, Accept itsappetitable and appreciatable value, every parts of Prunuspseudocerasus Lindl.can be used to treat some kinds of disease inChina traditional medicines. However, the studie about chemicalconstituents and pharmacological activities on Prunuspseudocerasus Lindl. are very little, so it is important to study Prunuspseudocerasus Lindl.In our report, 6 compound were isolated by organic solvent andcolumn chromatography and the structure of 4 compounds wereidentified through 1H-NMR, 13C-NMR and MS .They areKaempferol-3-O-α-L-rhamnoside , Quercetin-3-O-α-L-rhamnoside,...
