Triterpene-farnesyl hydroquinone conjugates from .

Two new lanostane-type triterpenoids characterized with farnesyl hydroquinone moieties, ganocalidoins A () and B (), were isolated from the fruiting body of , together with two known tripterpenes (-). The structures of compounds and were determined by extensive spectroscopic data including HRESIMS, 1D and 2D NMR. Ganocalidoins A and B showed anti-oxidant capacity with IC values of 38.7 ± 2.8 and 34.2 ± 1.8 μM, respectively. The compounds did not show tyrosinase inhibition activity.
