A new triterpene saponin (1) was isolated from a methanol extract of Swartzia apetala Raddi var. glabra, together with the flavonoids mauritianin (2), kaempferol (3) and the triterpene saponin β-D-glucopyranosyl 3β-hydroxy-olean-12-en-28-oate (4). These compounds were characterised on the basis of
Fractionation of an ethanolic extract of Swartzia polyphylla, guided in part by an assay for inhibition of protein kinase C, led to the isolation of the known flavonoids biochanin A, dihydrobiochanin A, ferreirin, dalbergioidin, and naringenin, and one new prenylated isoflavonone,
The methanolic extract of Swartzia polyphylla DC. heartwood had antibacterial activity against cariogenic bacteria, the mutans Streptococci. The chromatographic purification of the extract afforded seven flavonoids. Among them, three known isoflavanones, dihydrobiochanin A, ferreirin and
The 95% ethanol extract of the bark of Swartzia polyphylla DC (Fabaceae) possesses important larvicidal, antimycobacterial and antifungal activity in vitro. Bioassay-guided studies performed on the crude ethanol extract afforded T-cadinol as the larvicidal and anti-Mycobacterium tuberculosis
Natural products are sources of inspiration and reservoir of high valuable molecules. Recently, analytical tools based on liquid chromatography coupled to tandem mass spectrometry to generate molecular network became widely employed for dereplication. This strategy greatly accelerates the
