This research was designed to isolate pinostrobin from Kaempferia pandurata Roxb. rhizome using a chromatography method and to study its structural modification through ethylation and allylation reactions. Two compounds were afforded from the ethylation reaction that were 5-ethoxy-7-methoxyflavanone and 4′-ethoxy-6′-methoxychalcone and in the case of the allylation, 5-O-allylpinostrobin (5-allyloxy-7-methoxyflavanone) and 6-allylpinostrobin (6-allyl-5-hydroxy-7-methoxyflavanone) were obtained.
