C-glycosylflavones from prosopis chilensis

ABSTRACT

Five apigenin-based C-glycosylflavones were isolated from the leaves and pods of Prosopis chilensis and identified as vicenin-1, 6-O-acetylvicenin-1, vicenin-2, vitexin and isovitexin. 6-O-acetylvicenin-1 could be a new acylated di-C-glycosylflavone and vicenin-1 is reported here for the first time in the genus Prosopis. The structures of the isolated compounds were established through spectroscopic analyses including 2D-NMR [HMQC, HMBC]
