The phytochemical study of Sida rhombifolia L. (Malvaceae) led to the isolation through chromatographic techniques of eleven secondary metabolites: sitosterol (1a) and stigmasterol (1b), sitosterol-3-O-β-d-glucopyranoside (2a) and stigmasterol-3-O-β-d-glucopyranoside (2b), phaeophytin A (3), 173-ethoxypheophorbide A (4), 132-hydroxy phaeophytin B (5), 173-ethoxypheophorbide B (6), 5,7-dihydroxy-4'-methoxyflavone (7), cryptolepinone (8) and a salt of cryptolepine (9). Their structures were identified by 1H- and 13C-NMR using one- and two-dimensional techniques. In addition, the vasorelaxant activity of cryptolepinone in rat mesenteric artery rings is reported herein for the first time.
