O-p-D-galactopyranoside

Licania pittieri Prance is a tree up to 15 meters high growing in the cloud forests at 1800 m in altitude. From the methanol extract of the leaves, collected in the Parque Nacional Henry Pittieri, oleanolic acid (1), ursolic acid (2), catechin (3), epicatechin (4), quercetin (5), and four glycosidic derivatives, quercetin 3-O-P-D-galactopyranoside (6), quercetin 3-O-P-D-glucopyranoside (7), quercetin 3-O-a-L-rhamnopyranoside (8), and quercetin 3-O-a-L-arabinopyranoside (9) were identified directly by comparing their spectroscopic data with those reported in the literature and/or authentic samples [see Fig. (1)] [5]. 

Two flavonoid glycosides eupalitin 3-0-p-D-galactopyranosyl-(l->2)-P-D-glucopyranoside (1) and eupalitin 3-O-P-D-galactopyranoside (2) were isolated from the methanolic extract of Boerhawia repens...
