A pyridyl alkaloid and benzoic acid derivatives from the rhizomes of Anemarrhena asphodeloides

Abstract

A pyridyl alkaloid, 3-pyridylcarbinol (1) and benzoic acid derivatives, 4-hydroxy benzoic acid (2), 4- hydroxyactophenone (3), vanilic acid (4), and benzoic acid (5) were isolated from the rhizomes of Anemarrhena asphodeloides on the basis of spectroscopic and physicochemical analyses including 1D- and 2D- NMR techniques as well as by comparison of their data with the published values. Compounds 1 - 5 were isolated for the first time from this plant source.
