[Chemical constituents of Conyza blinii Lévl]
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, 1HNMR, 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.
