Abstract

Indigofera conferta, an annual herb widely distributed in northeastern and western Nigeria, is used ethnomedicinally to treat inflammation, pain, sore feet, and snakebite. Despite these uses, the phytochemical constituents of this species remain underexplored. The chloroform fraction of the methanol extract of the aerial parts of I. conferta was separated by silica gel column chromatography to afford a compound. The structure of the compound was elucidated using UV, FT-IR, one-dimensional and two-dimensional NMR (¹H, ¹³C, HSQC, and HMBC) spectroscopy and comparison with previously reported literature data. The compound was assigned as 3,5-dimethoxy-4'-O-(2,3-dihydroxy-3-methylbutyl)-dihydrostilbene. This report documents the first isolation of this compound from I. conferta and contributes to the phytochemical and chemotaxonomic knowledge of the genus Indigofera.
