- Phytochemical investigation of the methanol extract from the entire plant of Atraphaxis spinosa L from Armenia led to the isolation of quercitrin(1), afzelin(2), N-trans-p-coumaroyldopamine (3), N-trans-feruloyldopamine (4), quercetin 3-O-β-D-glucuronide-6″-methyl ester (5), myricitrin (6), quercetin-3-O-β-D-glucuronide (7), 2″-galloyl-quercetin-3-O-β-D-glucuronide (8), 2-(β-D-glucopyranosyloxy) -4-hydroxy-6-methoxyacetophenone (9), fisetinidol (10), methyl gallate (11), gallic acid (12), α-linolenic acid (13), loliolide (14), N-trans-feruloyltyramine (15), and lucidulactone A (16). The structures were elucidated by 1D and 2D homonuclear and heteronuclear NMR spectroscopy and by comparison with closely related compounds published previously. In the present research, compounds 1, 2, 5, 7–9, 11, 13, 14, 16 are reported for the first time from genus Atraphaxis. Compounds 5, 8, 9, 14, 16 have not been reported previously from any species in the Polygonaceae. The chemotaxonomic significance of the isolated compounds is discussed.
