The MeOH extract of the aerial parts of Artemisia asiatica significantly inhibited the xanthine oxidase (XO) induced uric acid production. Flavonoids were isolated from the active extract and identified as eupatilin (1), hispidulin (2), jaceosidin (3), cirsilineol (4), 5,7,4’,5’-tetrahydroxy-6,3’-dimethoxyflavone (5), 6methoxytricin (6) and chrysosplenetin (7). With the exception of cirsilineol...

In the title compound, [Cr(C(15)H(10)O(2))(CO)(3)], the Cr(CO)(3) unit exhibits a three-legged piano-stool conformation. The chromium metal centre is coordinated by the phenyl ring of the flavone ligand [Cr-(phenyl centroid) distance = 1.709 (1) Å]. The ligand is approximately planar, the dihedral angles between the γ-pyrone ring and the phenyl ring and between the γ-pyrone and the phenyl-ene r...

Herbs, known for their naturally active chemicals, are currently being reconsidered as a safer alternative medication. The natural substances that to have lots of bioactivities, such antioxidant properties, mangosteen (Garcinia mangosatana L.) (GM) and kodavan (Centella asiatica L. Urban) (CA). However, the activities GM-CA combination not been previously reported. It is essential investigate p...

High-performance liquid chromatography-atmospheric pressure chemical ionization mass spectrometry was used to identify flavone aglycones and glycosides in soybean pods. Tandem mass spectrometry (MS-MS and MS-MS-MS) and photodiode array detection were also utilized in flavone characterization. A total of seven flavone aglycones and glycosides were identified. Among them three flavone aglycones--...

Following inoculation with the anthracnose pathogen Colletotrichum sublineolum, seedlings of the sorghum resistant cultivar SC748-5 showed more rapid and elevated accumulation of luteolin than the susceptible cultivar BTx623. On the other hand, apigenin was the major flavone detected in infected BTx623 seedlings. Luteolin was demonstrated to show stronger inhibition of spore germination of C. s...

I . The oxidative stability of lipids in the tissues (erythrocytes, liver and depot fat) from vitamin E-deficient rats was not improved by feeding these animals, for a period of 39-55 days before killing, on a vitamin E-free diet richly supplemented with the flavonoid antioxidants quercetin (3,s ,7,3’,4’-pentahydroxyflavone) and flavone (3,7,8,~’,5’-pentahydroxy-6tert.-butyl flavone). z. Additi...
