Phenolic compounds from the stem bark of Saccopetalumhors fieldii Benn

摘要

Column chromatographic separation of the methanol extract from the Saccopatlumhorsfieldii Bennrsquo;sstem bark yielded four phenolic components including three flavonoids, kaempferol-3,4rsquo;-dimethylether(1), quercetin-3,7- dimethylether(2), quercetin-3,7,4rsquo;-trimethylether(3), and one alkaloid, liriodenine (4). The structures of these compounds were determined based on UV, IR, HRESIMS, 1Dand2DNMR data.
