Three polyacetylenes were isolated and purified from Platycodon grandiflorum A. DC for the first time by high-speed counter-current chromatography using a two-phase solvent system composed of hexane/ethyl acetate/methanol/water (1:31:1:31, v/v/v/v) and high-performance liquid chromatography with an
In an ongoing project directed toward the discovery of novel treatments for diabetic complications from traditional herbal medicines, fifteen compounds, apigenin (1), apigenin-7-O-beta-D: -glucopyranoside (2), apigenin-7-O-(6''-O-acetyl)-beta-D: -glucopyranoside (3), luteolin (4),
A new polyacetylene, namely isolobetyol (1), was isolated from the root of Platycodon grandiflorum (Jacq.) A. DC., together with lobetyol (2), lobetyolin (3), and trans-2-hexenyl β-D-glucoside (4). The structures of the isolated natural products were
