Further dihydrochalcones from Crotolaria ramosissima

Abstract

Duas novas 2,3-diidrohalconas crotaramin (2) e crotin (3) foram isoladas da planta da Índia Crotolaria ramosissima. Suas estruturas foram elucidadas por meio de intenso uso de espectroscopia de RMN uni-e bidimensional, incluindo HMBC e NOESY.Two new dihydrochalcones, crotaramin (2) and crotin (3), have been isolated from the Indian plant Crotolaria ramosissima. Their structures have been elucidated by extensive one-and two-dimensional NMR spectroscopy including HMBC and NOESY.
