Six dibenzo-1,4-dioxane derivatives (1–6) were isolated from the roots of a Hypericaceous plantHypericum ascyron. Spectroscopic analyses revealed2and4–6to be new compounds. The partial racemic natures of1–3were concluded by chiral HPLC analyses, while5was confirmed to be a racemate. The absolute configurations1–4were deduced on the basis of ECD calculations. Biological activity evaluation of the dibenzo-1,4-dioxane derivatives along with two related compounds: hyperdioxanes A (7) and B (8), previously isolated from the same plant material by our group demonstrated that7exhibit an anti-HIV activity (IC505.3 μM, TI 7.2) while8showed an inhibitory effect on IL-1β production (inhibition rate: 72.3% at 6.3 μM) from LPS-stimulated microglial cells.
