Tyrosinase inhibitory activity of flavonoids from Artocarpus heterophyllous.
BACKGROUND Tyrosinase is an oxidoreductase that is very important in medicine and cosmetics because the excessive production of melanin causes hyperpigmentation. The development of novel, effective tyrosinase inhibitors has long been pursued. In preliminary tests, we found that an extract of the wood of Artocarpus heterophyllous (AH) potently inhibited tyrosinase activity. RESULTS Two new fla...
متن کاملFlavonoids and triterpenes from the leaves of Artocarpus fulvicortex.
Five flavonoids, 5-hydroxy-(6:7,3':4')-di(2,2-dimethylpyrano)flavone 1, carpachromene 2, cycloartocarpesin 3, norartocarpetin 4 and 2'-hydroxy-4,4',6'-trimethoxychalcone 5, along with three triterpenes, friedelin 6, lupeol 7 and 13-sitosterol 8 were isolated for the first time from the leaves of Artocarpus fulvicortex F.M. Jarrett. The structures of these compounds were established by analysis ...
متن کاملScreening of Antibacterial Activity of the Essential Oil from Seed of Artocarpus Heterophyllus
The objective of this work is to investigate the antibacterial activity of Artocarpus heterophyllus plant. The antibacterial activity of essential oil obtained from plant was examined. To evaluate the antibacterial activities of these extracts; their in vitro antibacterial activities were determined by disk diffusion testing and minimum inhibitory concentration (MIC). Escherichia coli, Pseudomo...
متن کاملCytotoxic prenylflavonoids from Artocarpus elasticus.
Five new prenylated flavonoids, artelastoheterol (1), artelasticinol (2), cycloartelastoxanthone (3), artelastoxanthone (4), and cycloartelastoxanthendiol (5), along with five known compounds, were isolated from the root bark of Artocarpus elasticus. The structures of 1-5 were elucidated by spectroscopic methods and through comparison with data reported in the literature. The previously known c...
متن کاملSimultaneous HPLC Analysis of Three Flavonoids in the Extracts of Artocarpus heterophyllus Heartwoods
− A reversed-phase high-performance liquid chromatographic method is described for the simultaneous determination of three antibacterial flavonoids, artocarpanone, artocarpin, and cycloartocarpin in ethyl acetate extracts from Artocarpus heterophyllus heartwoods. Separation was achieved using a TSK-gel ODS-80Tm column (5 μm, 4.6 × 150 mm) at 25 oC with a gradient elution system of methanol and ...
