Flavonoids and phenylpropanoids from spathodea campanulata P. beauvais leaves

ABSTRACT

Fractionation and purification of the merhanolic extract of the leaves of Spathodea campanulata P. Beauvais cultivated in Egypt afforded six compounds identified as 1-O-caffeoyl-beta-D-glucopyranoside [1], kaempferol 3-O-[2-O-beta-D-xylopyranosyl]-beta-D-gaiacto-pyranoside [2], kaempferol 3-O-[6-O-alpha-L-rhamnopyranosyl]-beta-D-galactopyranoside [3], acteoside [4], kaempferol 3-O-[6-O-alpha-L-rhamnopyranosyl]-beta-D-gtucopyranoside [5] and quercetin 3-O-[2-O-beta-D-xylopyranosyl]-beta-D-galactopyranoside [6]. The structures of the isolated compounds were determined by physical, chemical and spectroscopic methods. All these compounds have been isolated for the first time from the genus spathodea
