| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

Cytotoxic activities of flavonoids from Centaurea scoparia.[Pubmed:25114960]
ScientificWorldJournal. 2014;2014:274207.
Phytochemical studies on the ethanolic extract of the aerial parts of Centaurea scoparia led to the isolation of two new flavonoids, 3',4'-dihydroxy-(3'',4''-dihydro-3''-hydroxy-4''-acetoxy)-2'',2''-dimethylpyrano- (5'',6'':7,8)-flavone-3-O- beta -D-glucopyranoside (1) and 3,3',4'-trihydroxy-(3'',4''-dihydro-3'',4''-dihydroxy)-2'',2''-dimethylpyrano-(5' ',6'':7,8)-flavone (2), along with eight known flavonoids isolated for the first time from this plant, cynaroside (3), Apigetrin (4), centaureidin (5), oroxylin A (6), 5,7-dihydroxy-3',4',5'-trimethoxyflavone (7), atalantoflavone (8), 5-hydroxy-3',4',8-trimethoxy-2'',2''-dimethylpyrano (5'',6'':6,7)-flavone (9), and 3',4',5,8-tetramethoxy-2'',2''-dimethylpyrano (5'',6'':6,7)-flavone (10). The structures of the isolated compounds were elucidated by means of spectroscopic tools including 1D and 2D NMR, UV, IR, and mass spectroscopy. Cytotoxic activities of the isolated compounds were evaluated against human cervical carcinoma HeLa, human hepatocellular carcinoma HepG2, and human breast carcinoma MCF-7. Compound 2 was the most potent cytotoxic agent against HeLa cells with an IC50 0.079 muM.
