Abstract: Fourteen phenolics were isolated from the whole plant of Ceratostigma minus Stapf ex Prain. Two of them were elucidated as new compounds, plumbocatechins A (1) and B (2). The others were identified as known compounds, plumbolactone A (3), plumbagic acid (4), isoshinanolone (5), epiisoshinanolone (6), N- trans-caffeoyl-tyramine, N- trans-feruloyltyramine, apocynin, vanillic acid, syringic acid, gallocatechin, ( + )-catechin and 1,2,6-tri-O-galloylglueose. The structure elucidation of the two new compounds were mainly achieved by 2D-NMR techniques.

Key words: Ceratostigma minus, Plumbaginaceae, Phenolics, Plumbocatechins A and B
