Two so far undescribed prenylated acylphloroglucinol derivatives were isolated from Hypericum coris (hypercorisins A-B) together with their two, also yet undescribed, peroxide derivatives (hypercorisins C-D), and seven known compounds (2-geranyloxy-1-(2-methylpropanoyl)-phloroglucinol, sucrose, vanillic acid 4-O-β-D-glucoside, chlorogenic acid, neochlorogenic acid, shikimic acid, quercitrin). The structures were determined by means of 1D and 2D NMR experiments and high-resolution mass spectrometry. Hypercorisins A, B and D induced complete inhibition of the gram-positive bacterium Bacillus subtilis at the highest concentration tested (100 μM) but showed no appreciable antibacterial effect on the gram-negative Aliivibrio fischeri nor cytotoxic activity on PC-3 or HCT-116 cancer cell lines.
