Resumo

WU, MING-DER et al. CHEMICAL CONSTITUENTS FROM THE MYCELIA OF ANTRODIA CINNAMOMEA. J. Chil. Chem. Soc. [online]. 2007, vol.52, n.4, pp.1338-1340. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072007000400016.

The mycelia of Antrodia cinnamomea (BCRC 36799) were extracted and four compounds were purified: one new benzoquinone, 5-methyl-benzo[1,3]dioxole-4,7-dione (1), one new benzenoid, isobutylphenol (2), along with two known benzoquinone derivatives, 2,3-dimethoxy-5-methyl[1,4]benzoquinone (3), 2-methoxy-5-methyl[1,4]benzoquinone (4). Their structures were elucidated by intensive MS and 2D NMR study. These compounds were evaluated for their antioxidant activities in the 1,1-diphenyl-2-picrylhydrazyl (DPPH) and supero xide radical scavenging assay. Preliminary antioxidant activity data revealed that compound 4 showed a poor radical scavenging activity

Palavras-chave : Antrodia cinnamomea; Polyporaceae; mycelium; antioxidant; DPPH.
