Objective:
To study the chemical constituents of Nerviliae fordii.
Methods:
The compounds were isolated by silica gel and sephadex LH-20 column chromatography. Their structures were elucidated on the basis of physico-chemical properties and spectral datas.
Results:
Five compounds were isolated and identified as rhamnocitrin (1), rhamnazin (2), rhamnocitrin 3-O-beta-D-glucopyranoside (3), rhamnocitrin 4'-O-beta-D-glucopyranoside (4) and 4-hydroxybenzonic acid (5).
Conclusion:
Compound 3, 4, and 5 are isolated from this plant for the first time.
