Two new gallotannins, pistafolins A (1) and B (2), were isolated from the leaf extract of Pistacia weinmannifolia. Their structures were determined by spectral methods. Four known gallotannins (3 - 6), seven known flavonoid glycosides (7 - 13), along with 1-O-β-D-(6′-O-galloyl)-glucopyranosyl-3-methoxy-5-hydroxybenzene (14), gallic acid (15), methyl gallate (16), (+)-catechin (17), and (+)-gallocatechin (18), were also isolated. Some of these compounds were tested for their cytotoxicity toward K562 cells, and two small molecular phenolic compounds, 15 and 18, showed significant inhibitory effects with IC50 values less than 5 μg/ml.
