Phenylpropanoids from the Immature Fruits of Black Nightshade (Solanum nigrum L.)

Black nightshade (Solanum nigrum L.) has been traditionally used as indigenous Chinese medicine. Phytochemical investigations of the immature fruits S. have carried out and nine phenylpropanoids (1-9) were obtained. Their structures elucidated on basis spectroscopic chemical methods, including MS, 1H 13C-NMR. They identified (7S, 8R)-4-[3-hydroxymethyl-5-(3- hydroxypropyl)-2,3-dihydrobenzofuran-2-yl]-2-methoxyphenol (1), 8R)- dihydrodehydroconifery alcohol (2), massonianoside A (3), butane-2,3-diol 2-O- (6-O-caffeoyl)-β-D-glucopyraniside (4), 4-[(6-O-(E)-caffeoyl)-β-D-glucopyranosyl] vanillic acid (5), (+)-isolariciresinol (6), trans-cinnamic (7), ferulic (8), 4-hydroxy cinnamic (9). This study enriched constituents black nightshade.
