Pomegranate pomegranate pomegranate Branch (Punicaceae) the genus (Punica L.) plants pomegranate (Punica granatum L.) dried petals . In Xinjiang folk medicine has a long history , with the elimination heat , anti-inflammatory, anti-corrosion solid the teeth, the antidiarrheal Zhilishen the efficacy . Predecessors mainly research granatum few pomegranate research , this thesis, the face of the pomegranate were mainly from the following three : First a qualitative analysis of the chemical composition of pomegranate , through qualitative analysis found that pomegranate flowers contain flavonoids, anthraquinone , sugars , saponins, amino acids , polypeptides , cardiac glycosides , organic acids, etc. . Total flavonoid content as an indicator by spectrophotometry , drawn by four factors and three levels orthogonal experiment the optimum conditions of flavonoids in the ethanol extract of pomegranate : 45% ethanol in the extraction temperature was 60 ℃, solid-liquid ratio of 1:40 condition extraction 0.5 h . Total flavonoids measured under these conditions was 62.70 mg / g. 3 Shiliuhua extracted with 60% ethanol at room temperature several times, the extract was concentrated under reduced pressure alcohol was obtained extract , the extract washed with water suspended , washed with petroleum ether, diethyl ether , ethyl acetate , n-butanol for extraction , and further using silica gel column chromatography , seven compounds were identified from the ether , ethyl acetate and n-butanol three extraction sites isolated : kaempferol , quercetin , rutin . Compound Ⅲ structure to be determined.
