摘要

A new pyridine, 1-(4-methylpyridin-2-yl)ethyl acetate (1) as well as xanthyletin (2), 7,4′-dimethoxyisoflavone (3), 5-hydroxy-7,4′-dimethoxyisoflavone (4), (+)-lariciresinol (5), (+)-5,5′-dimethoxylariciresinol (6), and (+)-medioresinol (7), were isolated from the roots of Physalis peruviana L. The structure of the new pyridine was elucidated by chemical and physical evidence.
