dryopteris crassirhizoma/抗真菌薬

OBJECTIVE To examine the antifungal effect of different extract of Dryopteris fragrans (L.) Schott. in vitro, and screen the effective fraction from those extracts. METHODS Separated the Dryopteris fragrans extract and got four parts by refluxing extraction,and determined the contents of total

Pseudoaspidinol is a phloroglucinol derivative with Antifungal activity and is a major active component of Dryopteris fragrans. In our previous work, we studied the total synthesis of pseudoaspidinol belonging to a phloroglucinol derivative and investigated its antifungal activity as well as its

One new sesquiterpene and six known compounds were isolated from Dryopteris fragrans (L.) Schot. They were identified as 3-O-β-D-glucopyranosylalbicanol- 11-O-β-D-glucopyranoside (1), dihydroconiferylalcohol (2), (E)-3-(4-hydroxyphenyl)acrylic acid (3), esculetin (4),

Fatty acid synthase (FAS) is emerging as a potential therapeutic target to treat cancer and obesity. Bioassay-guided fractionation of a MeOH extract of the rhizomes of Dryopteris crassirhizoma (Dryopteridaceae), using an in vitro FAS inhibitory assay, resulted in the isolation of a series of

The antimicrobial effect of solvent extracts from the rhizome of a thick-stemmed wood fern (Dryopteris crassirhizoma) was evaluated and its phloroglucinol components, flavaspidic acids PB and AB. Flavaspidic acids PB and AB were isolated from the D. crassirhizoma rhizomes by methanol extraction,

BACKGROUND Dryopteris fragrans (L.) Schott is a deciduous perennial herb, which has been used traditionally for treatment of ringworm infections and others skin diseases in the north of China. OBJECTIVE To characterize the chemical composition, evaluate the antifungal activity and explore possible

Porcine reproductive and respiratory syndrome virus (PRRSV) represents a significant challenge to the swine industry worldwide. Current control strategies against PRRSV are still inadequate and there is an urgent need for new antiviral therapies. Flavaspidic acid AB (FA-AB) is a compound derived
