Puddumin-B, a New Flavanone Glycoside from Prunus cerasoides

Abstract

Puddumin-B, a new flavanone glycoside (naringenin-4′-methyl-ether - 7-O-β-D-galactoside) has been isolated from Prunus cerasoides and characterised by spectroscopic and chemical methods.

Prunus cerasoides D. Don (syn. P. puddum Rosaceae), is a tree distributed in the temperate Himalayas to an altitude of 1700 m (1,2). The stems are reported to be antipyretic, refrigerant and useful in vomiting, leprosy and leucoderma (1,2). Chemical examination of P. cerasoides has been done by various workers (3–12). The present paper reports the isolation, and characterisation of a new flavanone glycoside, naringenin-4-methyl ether-7-O-β-D-galactoside from the stem bark of P. cerasoides.
