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. |

Bioactive constituents from Chinese natural medicines. XI. inhibitors on NO production and degranulation in RBL-2H3 from Rubia yunnanensis: structures of rubianosides II, III, and IV, rubianol-g, and rubianthraquinone.[Pubmed:12808242]
Chem Pharm Bull (Tokyo). 2003 Jun;51(6):654-62.
Three new arborinane-type triterpene glycosides, rubianosides II, III, and IV, a new arborinane-type triterpene, rubianol-g, and a new anthraquinone, Rubianthraquinone, were isolated from a Chinese natural medicine, the roots of Rubia yunnanensis. The structures of the new constituents including their absolute configurations were determined on the basis of chemical and physicochemical evidence. The inhibitory effects of the isolated constituents on nitric oxide production in lipopolysaccharide-activated macrophages were examined. Among them, a cyclic peptide constituent, RA-XII and its aglycon, RA-V (deoxybouvadin), potently inhibited overproduction of nitric oxide and induction of inducible nitric oxide synthase. In addition, an anthraquinone constituent, 2-methyl-1,3,6-trihydroxy-9,10-anthraquinone, was found to show inhibitory effects on the release of beta-hexosaminidase in RBL-2H3 cells.
