A new lanostanoid, 19-nor-lanosta-5(10),6,8,24-tetraene-1α,3β,12β,22S-tetraol (1), characterized by the presence of an aromatic B ring and hydroxylated at C-1, C-3, C-12, and C-22, was isolated from an endophytic fungus, Diaporthe sp. LG23, inhabiting leaves of the Chinese medicinal plant Mahonia

A new ergosterol derivative, 23R-hydroxy-(20Z,24R)-ergosta-4,6,8(14),20(22)-tetraen-3-one (1), and a biosynthetically related known compound, (22E,24R)-ergosta-4,6,8(14),22-tetraen-3-one (2), were isolated from the co-culture between endophytic fungus Pleosporales sp. F46 and endophytic bacterium

Two new α-pyrones, fupyrones A and B (1 and 2) and a biosynthetically related known α-pyrone, 4-methyl-5,6-dihydro-2H-pyran-2-one (3), were isolated from an endophytic fungus, Fusarium sp. F20, harbored in the stems of the Chinese medicinal plant Mahonia fortunei. Their structures were determined on

Both the root and stem bark of Mahonia species were popular folk medicines. The plant has several proven biological activities including anti-bacterial, anti-fungal, and anti-inflammatory effects. However, Mahonia has not been studied for its anticancer effects. In the present study, we made

Berberine (BBR), the principle component for many medicinal plants such as Coptis chinensis Franch., Phellodendron chinense Schneid., and Mahonia bealei (Fort.) Carr., possesses diverse pharmacological activities, including anti-bacterial, anti-inflammatory, antitumor, hypolipidemic and antidiabetic

Protoberberinium salts, i.e. berberine (I), palmatine (II) and jatrorrhizine (III) prepared from Mahonia aquifolium (Pursh) Nutt. belong to isoquinoline alkaloids possessing interesting biological activity (e.g. antibacterial, antimalarial, antitumor). The characteristic UV/Vis absorption band

Extracts or alkaloids isolated from Mahonia aquifolium exhibit antimicrobial activity against Gram-positive and Gram-negative bacteria, fungi, and protozoa. In this study the bacteriostatic and bacteriocidal activities of a M. aquifolium extract and two of its major alkaloids, berberine chloride and

The crude extract of Mahonia aquifolium (Pursh) Nutt. stem bark and its two main protoberberine alkaloids, berberine and jatrorrhizine, were tested for their in vitro antimicrobial activity. Twenty strains of coagulase-negative staphylococci and 20 strains of Propionibacterium acnes isolated from

Ethanolic extracts of the stems and leaves of Nandina domestica, Mahonia fortunei, Mahonia bealei and Berberis thunbergii were tested for their antibacterial and antifungal activity. Most of the extracts have been proved to be active against Gram(+) bacteria.

The number of fully active antibiotic options that treat nosocomial infections due to multidrug-resistant Acinetobacter baumannii (A. baumannii) is extremely limited. Magnolia officinalis, Mahonia bealei, Rabdosia rubescens, Rosa rugosa, Rubus chingii, Scutellaria baicalensis, and Terminalia chebula

Chamiside A (1), a novel cytochalasan with a new 6/6/5-fused tricyclic core skeleton, was isolated from an endophytic fungus, Chaetomium nigricolor F5, harbored in the medicinal plant Mahonia fortunei. Its structure was unambiguously determined by extensive spectroscopic analyses, measurement of
