Phenolic compounds from leafy shoots of A. uva-ursi (Ericaceae) were studied. The new phenolic glycoside 6aEuro(3)-galloylpicein and 40 known compounds were isolated. Roots of A. uva-ursi afforded 16 compounds. A C-glycoside of bergenin was found for the first time in the family Ericaceae. The dominant components of A. uva-ursi leaves according to HPLC were arbutin, (+)-catechin, and corilagin; of stems, picein and (+)-gallocatechingallate; of roots, (-)-epicatechin, (-)-epicatechingallate, and (+)-catechin.
