[摘要]:A new phloroglucinol derivative possessing citran skeleton, petiolin D (1), and a new chromone glucoside, petiolin E (2), were isolated from aerial parts of Hypericum pseudopetiolatum var. kiusianum. The structures of I and 2 were elucidated by spectroscopic data, and a single-crystal X-ray diffraction analysis of 1 revealed that 1 was a racemic mixture. |
