Abstract


Phytochemical investigation of the stem barks of Ehretia longiflora Champ. afforded menisdaurin and rosmarinic acids. Their chemical structures were identified by combination of 1D-, 2D-NMR, and ESI-MS techniques in comparison with the literature. Menisdaurin acid was isolated for the first time from Ehretia species.
