Study on Isolation and Determination Structure Some Compounds of the Chloroform Extract of Male Carica Papaya Flowers From Quang Nam - Da Nang

Male flowers of Carica papaya are widely used in folk to treat respiratory diseases. In this research, male papaya flowers are collected in some places of Danang city and Quangnam province. Pretreated ingridients are fractionally extracted with methanol solvent. Total methanol extract is fractionally separated by solvents with increasing polarization: n-hexane, chloroform, dichloromethane and ethyl acetate respectively. This article is about the chemical compounds of chloroform extraction. Three known compounds, rutin (1), acid gallic (2), daucosterol (3) are isolated and determinated in structure from the chloroform extract of male Carica papaya flowers. Their structure are determined by analysis of MS, NMR spectra, and compared with the published data.
