Chemical constituents of Glycosmis parva branches

Abstract

Phytochemical investigation of Glycosmis parva Craib (Rutaceae) branches using several chromatographic techniques led to the isolation of 5 compounds. Beta-sitosterol and stigmasterol were obtained as a mixture of steroidal compounds. Three acridone alkaloids, namely N-methylataphilline, 5-hydroxy-N-methylseverifoline and 5-hydroxy-noracronycine were isolated. Inaddition, an unknown acridone analogue was also isolated. This compound still needs more 2D-NMR experiment before its structure can be established. Structure determination of all of the known compounds was accomplished through extensive spectroscopic studies, including comparison of their UV, IR, MS and NMR properties with the previous data of related compounds.
