Chemical constituents of the fruits of Gleditschia australis Hemsl.
From the methanolic extract of the fruits of Gleditschia australis Hemsl., a new flavonoid derivative 3"-O-menthiafoloylisovitexin (1) and a new carbohydrate ester of cinnamic acid 1-O-E-cinnamoyl-[2-O-E-cinnamoyl-alpha-L-rhamnopyranosyl-(1-->6)-beta-D-glucopyranoside] (2) have been isolated along with four known compounds, 1-O-E-cinnamoyl-[3-O-E-cinnamoyl-alpha-L-rhamnopyranosyl-(1-->6)-beta-D-glucopyranoside], isovitexin, luteolin, and quercetin. Their structures were elucidated on the basis of physical and spectroscopic evidence.
