A New Heterocyclization Product of Adhyperforin from Hypericum perforatum (St. John's Wort)

Abstract

From the aerial parts of Hypericum perforatum L. we have isolated phloroglucinol 1 (see the formula), a homologue of 2, the latter isolated previously from the same extract and identified by 2D NMR (DQF COSY, PS NOESY, TOCSY, HSQC and HMBC) [1].
