Flavanone, triterpene and chromene derivatives from the stems of Paramignya griffithii.
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.
