摘要：
Investigation of the stem bark of the unique Amazonian herbal plant Potalia amara yielded two new phenolic glycosides, potalioside A (1) and B (2), along with di-O-methylcrenatin (3), 2,6-dimethoxy-4-hydroxyphenol 1-glucoside and sweroside. The structures of potalioside A and B were established by interpretation of spectral data as 4-hydroxymethyl-2,6-dimethoxyphenyl 1-O-beta-D-glucopyranosyl(1 -> 6)-beta-D-glucopyranoside and 4-hydroxymethyl-2,6-dimethoxyphenyl 1-O-beta-D-xylopyranosyl(1 -> 6)-beta-D-glucopyranoside, respectively.
