RESUMEN
Six new polyphenols with different isoprenylated xanthones, isoprenylated acylphloroglucinols, and chromone architectures, hyperfaberols A-F (1-6), were isolated from the whole plants of Hypericum faberi along with seven other related known compounds. In which hyperfaberols A/B (1/2) and 12-13 were isoprenylated xanthones, hyperfaberols C-E (3-5) and 8-11 were seven isoprenylated acylphloroglucinol derivatives, while 6-7 were two chromones. Their structures were elucidated by comprehensive analysis of their spectroscopic data as well as detailed comparison with the literature data. Compounds 1 and 11 showed cytotoxities against the human esophageal cancer cell line (ECA-109) and the pancreatic tumor cell line (PANC-1) in vitro, respectively.
