Abstract

Abstract: The phytochemical investigation of the ethyl acetate fraction of Polygala longicaulis Kunth resulted in the isolation and identification of two dihydrostyryl-2-pyrones (1 –2 ). This is the third species of the Polygala L. genus, along with Polygala altomontana Lüdtke, Boldrini & Miotto and Polygala sabulosa A.W. Benn., to present the accumulation of dihydrostyryl-2-pyrones. The data reported herein make an important contribution to the chemotaxonomy of this genus. This is the first report of dihydrostyryl-2-pyrone (1 ) and dihydrometisticin (2 ) in P. longicaulis and the first report of dihydrometisticin in the genus Polygala . Furthermore, this is the first grouping of non-xanthone-producing Polygala species. Graphical abstract: Image 1 Highlights: The phytochemical investigation of Polygala longicaulis is reported. A grouping named non-xanthone-producing Polygala species is described. A chemical marker of three Polygala species is reported. The chemophenetic significance for the Polygala genus is related.
