New chromone derivative from Evolvulus alsinoides Linn. aerial parts

Phytochemical investigation of the aerial parts of Evolvulus alsinoides Linn. (Convolvulacae) resulted in the isolation of a new chromone characterized as 6-hydroxy-5-nonadecanoxychroman-2-one (alsinoideschromone) along with hexatriacontane, octyl octadec-9-enoate, nonyl octadec-9-enoate, dodecanyl-octadec-9,12-dienoate, tetracosanyl hexadec-9-enoate, heptacosan-14-β-ol, stigmast-5, 22-dien-3β-ol and stigmata-5-en-3β-ol. The structure of all these phytoconstituents have been established on the basis of spectral data analysis and chemical reactions.
