is a genus of fungi belonging to the Cytosporaceae family (Sordariomycetes, Ascomycota) considered as a prolific source of specialized metabolites due to their ability to produce diverse secondary metabolites with...

A new 3-arylcoumarin, 7-hydroxy-6-(1,1-dimethylallyl)-2',5'-dihydroxy-4'-(3,3dimethylprenyl)-3-arylcoumarin (desmoarylcoumarin) , a previously unreported oleanane-type triterpenoid, 3,22,23-trihydroxyolean-12-en (episoyasapogenol B) , together with five known flavonoids including darbergioidin (), isoferreirin (), quercetin (), vitexin (), swertizin...

Eleven previously undescribed arylnaphthalide lignans (-) together with seven known compounds were isolated from the whole plant of . The structures of - were elucidated by spectroscopic analysis and mass...

This paper describes eight new triterpenoid saponins, including afzeliioside A (), four acetylated afzeliiosides as pairs of inseparable regioisomers, called afzeliiosides B/C () and D/E (), afzeliiosides F-H (), and...

A previously unreported gallocatechin glycoside, (2 ,3) 4'--methyl-gallocatechin-3--α-ʟ-rhamnopyranoside () and an unseparable mixture of two previously undescribed dihydromyricetin glycosides, (2 ,3) 4'--methyl-dihydromyricetin-3--α-ʟ-rhamnopyranoside () and (2 ,3) 4'--methyl-dihydromyricetin-3--α-ʟ-rhamnopyranoside () along with...

The use of natural products for medicinal purposes is becoming more and more common nowadays, as evidenced by the presence in plants of secondary metabolites with different potentials such as...

Phytochemical investigation of the methanol extracts from the leaves and bark of resulted in the isolation of one new flavone -glycoside: apigenin-8--[6''-feruloyl]---glucopyranoside] (), together with sixteen known compounds including quercetin-3----rhamnoside...

A new triterpenoid saponin (Mimonoside D: 3---L-arabinopyranosyl-3-hydroxyolean-12-en-28-oic acid 28---D-xylopyranosyl-(1→2)--D- glucopyranoside ester ()) was isolated from the aerial parts of Sauvalle together with nine known compounds: 7,4'-dihydroxyflavone (), kaempferol (), lupeol...

Submerged mycelial cultures of the ascomycete   CCTU A372 were found to produce five previously undescribed tetramic acids, for which we propose the trivial names colposetins A-C (-) and colpomenoic...

The polar fraction of the MeOH extract of the roots of subsp. (Pourr.) Briq. (Caryophyllaceae) was investigated for its constituents and two previously unreported monodesmosides triterpene saponins, telephiifoliosides A and...
