Pectolinarin, a flavone heteroside, was isolated from Distictella elongata (Vahl) Urb. leaves ethanol extract, along with a mixture of ursolic, pomolic and oleanolic acids, besides β-sitosterol. Their structures were established on the basis of spectral analysis ( 1 H and 13 C NMR, 1 D and 2 D) and they were compared with literature. This is the first report on the occurrence of this flavonoid in a species of the Bignoniaceae family.
