Abstract:Objective:To study the chemical constituents in the air dried part of Conyza blinii.Method:The constituent isolation was done by solvent extraction together with column chromatography. Several methods,such as IR,HNMR,13CNMR and MS, were used to determine the structures of the isolated constituents.Result:Three compounds were isolated from the air dried part of Conyza blinii and identified as friedelinol,n-triacontanol and daucosterol on the basis of physical and chemical properties and spectroscopic analysis.Conclusion:These compounds have not been discovered previously in this plant.
