A new oxoaporphine from Sabia limoniacea var. ardisioides / 药学学报

The chemical constituents of Sabia limoniacea var. ardisioides were investigated using chroma­tographic methods, such as silica gel, Sephadex LH-20 and preparative HPLC. Eight compounds were isolated and their structures were elucidated by spectral data and physicochemical properties, which were identified as 5-methoxy-1,2-methylenedioxyl oxoaporphine (1), fuseine (2), N-p-feruloyltyramine (3), N-trans-coumaroyl tyramin (4), quercetin (5), rutin (6), mutabiloside (7), and protocatechuic acid (8). Among those, compound 1 is a new compound, compounds 2−8 were isolated from this plant for the first time.
