Objective To study the chemical constituents from the fresh fruits of Physalis pubescens. Methods Compounds were isolated and purified by repeated column chromatography on silica gel column, Sephadex LH-20 gel column, and preparative HPLC methods. Physicochemical properties and spectroscopic methods were employed for the structure elucidation. Results Twenty compounds were obtained and identified as osthol (1), xanthotoxin (2), isopimpinellin (3), imperatorin (4), (-)-meranzin hydrate (5), auraptenol (6), 1-(4-hydroxy-3,5-dimethoxyphenyl) ethanone (7), 2,5-dimethoxybenzoquinone (8), 2-(4-hydroxyphenyl) acetic acid (9), (S)-methyl 2-hydroxy-2-(4-hydroxyphenyl) acetate (10), pyrocatechol 1-O-β-D-glucopyranoside (11), benzyl β-D-glucopyranosyl (1→6)-β-D-glucopyranoside (12), 2-phenylethyl-O-β-D-glucopyranoside (13), p-hydroxybenzene propanoic acid (14), 3,4-dihydroxybenzene propionic acid (15), (1-O-p-coumaroyl)-(6-O-β-glucosyl)-β-glucoside (16), 1-O-trans-cinnamoyl-β-D-glucopyranosyl-(1→6)-β-D-glucopyranoside (17), N-trans-feruloyltyramine (18), kaempferol 3-O-β-D-glucopyranoside (19), and bergapten (20), respectively. Conclusion Compounds 1-16 are obtained from Physalis genus for the first time.
