| 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. |

| About Packaging | 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial. 2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial. 3. Try to avoid loss or contamination during the experiment. |

Isolation, purification, elucidation and cytotoxicity activity on oxidotaraxerone and oxidationtaraxerol of Cirsium setosum (Willd.) MB
Journal of Chinese Institute of Food Science & Technology,2014,14(3):196-204.
To investigate chemical constituents contained in cytotoxic petroleum ether-soluble portion from the ethanol extracts of Cirsium setosum (Willd.) MB, and evaluate their cytotoxic activity in vitro. The constituents were separated and purified by various chromatographic methods including silica gel and Sephadex LH-20, and their structures were elucidated by spectroscopic methods including NMR, MS methods and comparison with literature. Three oxidotaraxerane triterpenoids were isolated from the petroleum ether fraction of ethanolic extract of Cirsium setosum, and determined as 11α, 12α-oxidotaraxerone, 11α, 12α-oxidotaraxerol and 11alpha,12alpha-Oxidotaraxerol palmitate. To the best of our knowledge, this is the first report showing the presence of all the compounds in the genus Cirsium. In the in vitro assays, three compounds showed selective cytotoxicity against HCT-8, Bel-7402, BGC-823, A549 and A2780.
