Medicinal mushrooms Ophiocordyceps sinensis and Cordyceps militaris.

The main component of Ophiocordyceps sinensis and Cordyceps militaris extracts are polysaccharides. These are natural biopolymers that represent a large class of biologically active components. These contribute to their pharmacological activity and effect on health.

NMR and IR analysis of natural substances isolated from Cordyceps medicinal mushrooms.

There exist about 750 species of Cordyceps at present. A high price of natural Cordyceps and its lack in nature caused that the attention has been focused to its cultivation in laboratory conditions. The demand for this “fungus-parasite” is still quite high nowadays, as shown by the amount of commercial nutritional supplements.

Antioxidant Activity and Infrared Spectroscopy Analysis of Alcoholic Extracts Obtained from Paecilomyces hepiali (Ascomycetes).

This research studies the influence of substrate on the antioxidant activity of alcohol extracts of Paecilomyces hepiali. We used corn, rice, millet, and peas as substrates. Antioxidant activity was measured with the DPPH radical scavenging method.

The chain structure of [Ni(C(4)H(2)O(4))(C(12)H(8)N(2))(H(2)O)](n) with different types of fumarate bridging.

Using modified solvothermal conditions (longer cooling time), beside previously characterized dark-green crystals of [Ni(C(4)H(2)O(4))(C(12)H(8)N(2))] (main product), a few light-green crystals of the polymeric title compound, catena-poly[[aqua-(1,10-phenanthroline-κ(2)N,N')nickel(II)]-μ-fumarato-κ(2)O:O'-[aqua-(1,10-phenanthroline-κ(2)N,N')nickel(II)]-μ-fumarato-κ(4)O,O':O'',O'''], [Ni(C(4)H(2)O(4))(C(12)H(8)N(2))(H(2)O)](n) were isolated. Its crystal structure is made up from zigzag chains, propagating in [001], in which the Ni(2+) ions are linked alternatively by μ(2)-fumarato and bis-chelating fumarato bridging ligands. The Ni(2+) ion is coordinated in a deformed octa-hedral geometry by one chelating 1,10-phenanthroline ligand, one aqua ligand in a cis position with regard to both N-donor atoms and by two different fumarato ligands, each residing with its central C=C bond on an inversion centre, occupying the remaining coordination sites in a fac fashion.
