| Abstract: | Five compounds, including three that are novel, were isolated from the stems of Paramignya grifithii (Rutaceae). Two new and one known prenylated flavanones were characterized as 3',4'-dihydroxy-7-methoxy-8-(3-methylbut-2-enyl)-furano(4",5":6,5)-flava-adicin. In addition, a triterpene, 3-oxo-tirucalla-7,24-diene-21-al, and a novel chromene, 6-(2-hydroxyethyl)-2,2-dimethyl-2H-1-benzopyran, were identified. |
