Chemical characterizations dataset of flavonoid glycoside isomers and other constituents from Ficus deltoidea Jack

Abstract

Phytochemical data for Ficus deltoidea Jack, a plant widely studied for its anti-hyperglycemic effect, are scarce. In the pursuit of characterizing the chemical constituents of this species, extraction and purifications were conducted using multiple chromatographic procedures on selected varieties (var. deltoidea, var. kunstleri and var. trengganuensis). Twenty-two constituents were unambiguously identified through NMR, MS and UV data. These included gallocatechin (S1), afzelechin-4–8″-gallocatechin (S2), catechin (S3), afzelechin-4–8″-catechin (S4), afzelechin (S5), epicatechin (S6), hovetrichoside C (S7), 6,8-di-C-glucopyranosylapigenin (vicenin-2) (S8), afzelechin-4–8″-epiafzelechin (S9), epiafzelechin (S10), 6-C-xylopyranosyl-8-C-glucopyranosylapigenin (vicenin-1) (S11), orientin (S13), schaftoside (S14), 6-C-glucopyranosyl-8-C-xylopyranosylapigenin (vicenin-3) (S16), vitexin (S17), vitexin 2″-O-rhamnoside (S19), isovitexin 2″-O-rhamnoside (S20), 6,8-di-C-arabinopyranosylapigenin (S21), 6,8-di-C-xylopyranosylapigenin (S22), 6-C-arabinopyranosyl-8-C-xylopyranosylapigenin (S23), rhoifolin (S24) and cerberic acid A (S26). The presented phytochemical data can assist ethnobotanists, chemists, and natural product researchers in investigating the medicinal properties of F. deltoidea by facilitating the dereplication of its constituents.
