Abstract | ||||
From a methanolic ext. of the leaves of Juglans nigra L. (black walnut; Juglandaceae), kaempferol-3-O-β-glucoside, quercetin-3-O-β-glucoside and quercetin-3-Oβ-glucuronide-6"-Et ester were isolated for the first time, along with stigmasterol-3-O-β-glucoside. Most of the structures were established on the basis of UV, MS and NMR (1H, 13C-NMR and DEPT) spectroscopic data. Moreover, hypotensive and toxicol. studies were done. | ||||
