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

Phytochemical data for 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. , var. and var. ). Twenty-two constituents were unambiguously identified through NMR, MS and UV data. These included gallocatechin (), afzelechin-4-8″-gallocatechin (), catechin (), afzelechin-4-8″-catechin (), afzelechin (), epicatechin (), hovetrichoside C (), 6,8-di--glucopyranosylapigenin (vicenin-2) (), afzelechin-4-8″-epiafzelechin (), epiafzelechin (), 6--xylopyranosyl-8--glucopyranosylapigenin (vicenin-1) (), orientin (), schaftoside (), 6--glucopyranosyl-8--xylopyranosylapigenin (vicenin-3) (), vitexin (), vitexin 2″--rhamnoside (), isovitexin 2″--rhamnoside (), 6,8-di--arabinopyranosylapigenin (), 6,8-di--xylopyranosylapigenin (), 6--arabinopyranosyl-8--xylopyranosylapigenin (), rhoifolin () and cerberic acid A (). The presented phytochemical data can assist ethnobotanists, chemists, and natural product researchers in investigating the medicinal properties of by facilitating the dereplication of its constituents.
