Biflavonoids from the bark roots of Poincianella pyramidalis (Fabaceae)

Phytochemistry Letters, 2016
Poincianella pyramidalis (Fabaceae) is an endemic tree that grows in semiarid regions of Brazil. Phytochemical investigations on the bark roots of this plant led to the isolation of four new biflavonoids named (+)-5-hydroxy-7,4′-dimethoxyflavone-3α-2′′′-hydroxy-4′′′,4′′-dimethoxydihydrochalcone (1), (+)-5,7-dihydroxy-4′-methoxyflavone-3α-2′′′-hydroxy-4′

Purification and characterization of a Kunitz inhibitor from Poincianella pyramidalis with insecticide activity against the Mediterranean flour moth

Pesticide Biochemistry and Physiology, 2015
This paper describes the characterization of a trypsin inhibitor from Poincianella pyramidalis seeds (PpyTI). The partial sequencing of PpyTI revealed homology to Kunitz inhibitors, clustered as a member of Family I03 in MEROPS database. PpyTI has a single polypeptide chain of 19,042 Da and presents stability at high temperatures (up to 70 °C) and a ...
