Norartocarpetin, quercetin and naringenin were found to effectively inhibit 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) formation through trapping its phenylacetaldehyde and form their adducts in roast beef patties. Six adducts [8-C- or 6-C-(E-phenylethenyl) flavonoids] formed between
The investigation on the leaves of Morus alba L. was carried out to find the relationship of the constituents and the pharmacological activities. The isolation and purification were performed by various chromatographies such as silica gel, Sephadex LH-20, RP-C18 column chromatography and so on.
Two new chromenes, ficuformodiol A and ficuformodiol B, and nine known compounds including one chromene, spatheliachromen, six flavonoids, obovatin, carpachromene ( 5), apigenin ( 6), norartocarpetin ( 7), steppogenin, 6-prenylpinocembrin, one benzopyran, chromenylacrylic acid, and one isocoumarin,
The first stilbene possessing a γ-aminobutyric acid lactam function, artocarpene (1), and a new flavanone, 2-hydroxynaringenin 4'-O-β-d-glucopyranoside (2), were isolated from the stems of Artocarpus nitidus subsp. lingnanensis along with four known compounds, 2-hydroxynaringenin (3), oxyresveratrol
