Four new phenolic compounds (10, 12, 13 and 16) were isolated from the rhizome of Bergenia ciliata (Haw.) Sternb., together with (+)afzelechin, (+)catechin, quercetin-3-O-β-D-xylopyranoside, quercetin-3-O-α-L-arabinofuranoside, eryodictiol-7-O-β-D-glueopyranoside, arbutin, 6'-O-p-hydroxybenzoylarbutin, bergenin, 4-0-galloylbergenin, 11-O-galloylbergenin, p-hydroxybenzoic acid and protocatechuic acid. The structures of 10, 12, 13 and 16 were shown to be 6'-O-protocatechuoylarbutin, 11-O-p-hydroxybenzoylbergenin, 11-O-protocatechuoylbergenin and 6'-O-p-hydroxybenzoylparasorboside, respectively, on the basis of chemical and spectral data.
