FIVE COMPOUNDS FROM CERATOPHYLLUM DEMERSUM

Abstract

Ceratophyllum demersum is a traditional medicine used in Asian countries. This plant is native to Vietnam. This study was done to investigate the phytochemicals of plants of Ceratophyllum demersum grown in Lam Dong Province. Five compounds, cyclocolorenone (1), 1α-hydroxycyclocolorenone (2), lupeol (3), betullinic acid (4), and chakyunglupulin B (5) were isolated from the ethyl acetate extract of Ceratophyllum demersum. Their chemical structures were elucidated by comparing their spectroscopic data with previously reported data in the literature.
