Chemical constituents of Glycosmis citrifolia (WILLD.) LINDL. Structures of four new acridones and three new quinolone alkaloids

Abstract

The structures of two new dimeric acridone alkaloids, glycobismine-D (1) and -E (2), having a novel linkage as binary acridones, three monomeric acridones, glycocitrine-IV (3), -V (4), and -VI (5), and three quinolone alkaloids, glycocitlone-A (6), -B (7), and -C (8) from Glycosmis citrifolia (WILLD.) LINDL. (Rutaceae) have been elucidated by spectrometric studies.
