Pleonotoquinones, Cytotoxic Oxepinenaphthoquinones from .

Two unusual naphthoquinones, named here as pleonotoquinones A () and B (), were isolated along with two known anthraquinones ( and ) via chromatographic separations of an ethyl acetate extract of the roots of . Compounds and are the first examples of quinones bearing a 2-methyloxepine moiety. The compounds were isolated with the aid of mass spectrometry and molecular networking, and their structures were resolved using 1D and 2D NMR and HRESIMS data.

Recovery and partial purification of fibrinolytic protease from and and cytotoxic and antioxidant activity of their extracts.

Mushrooms are a source of primary and secondary metabolites. Little is known about the most suitable conditions for production of mushrooms by submerged fermentation. This article reports antioxidant and cytotoxic assays, in addition to quantitatively evaluating the content of proteases with fibrinolytic action in the crude extracts of two species of edible mushrooms produced in different formulations, as well as evaluating the recovery of these enzymes by aqueous two-phase systems (ATPS).
