Phytochemical Study of Glycosmis Mauritiana

摘要

Three quinolinone alkaloids, two acridone alkaloids and a flavones glycoside were isolated from the aerial parts of Glycosmis mauritiana. These compounds were characterized as 7, 8-Dimethoxy-2,2,6-trimethyl-pyrano quinolin-5-one, 4-Methoxy 1-methyl quinolin-2-one, 6-Hydroxy N-methyl 2,3-furo-quinolin-4-one, 1-Hydroxy-10-methyl acridone, 1- Hydroxy-2, 3-dimethoxy-10-methylacridin-9-one and Luteolin-4'-O-[α-L-rhamnopyranosyl-(1→2)-{α-L-rhamnopyra- nosyl-(1→6)}-β-D-glycopyranoside]. The isolated compounds were characterized by UV, IR and N. M. R (1H, 13C) studies.
