Petiolins J-M, prenylated acylphloroglucinols from Hypericum pseudopetiolatum var. kiusianum

Four new prenylated acylphloroglucinols, petiolins J−M (1−4), were isolated from aerial parts of Hypericum pseudopetiolatum var. kiusianum, and the structures were elucidated by spectroscopic data and a single-crystal X-ray diffraction analysis. Petiolin J (1) exhibited antimicrobial activity.
