The main objective of the study was to evaluate the dihydroflavonols from bark powder of an important medicinal plant, Lannea coromendelica (Houtt.) Merr. The chemical constituents of L. coromendelica bark acetone extract revealed five dihydroflavonol compounds and they are (2R,3S)-(+)-3',5-dihydroxy-4',7-dimethoxydihydroflavonol (1), (2R,3R)-(+)-4',5',7-trimethoxydihydroflavonol (2), (2R,3R)-(+)-4',7dimethyldihydroquercetin (3), (2R,3R)-(+)-4',7-di-O-methyldihydrokaempferol (4), (2R,3R)-(+)-4'-O-methyldihydroquercetin (5) by FT - IR and GC - MS. https://www.biotech-asia.org/vol7no2/ft-ir-and-gc-ms-studies-of-dihydroflavonols-from-bark-extract-of-lannea-coromendelica-houtt-merr/ Lannea coromendelica (Houtt.)
