Abstract: Calli and suspended cells of Hypericum perforatum accumulated xanthones with the 1,3,6,7 and 1,3,5,6-oxygenation pattern. Xanthone accumulation was highly influenced by hormone supplementation. Calli grown with 4.5 μmol/L 2,4-D + 2.3 μmol/L KIN had the highest specific xanthone production observed (0.73 percnt; DW). The use of BA instead of KIN reduced xanthone accumulation, resulting in the lowest production achieved (0.24 percnt; DW). This effect was attenuated when both hormones were present. Calli displayed a positive linear relationship between NAA concentration, in the range of 4.5-22.5 μmol/L, and total xanthone accumulation and the xanthone 1,3,6,7/1,3,5,6 ratio. However, the production of 1,3,5,6 xanthones was similar in all NAA concentrations studied.
