Rubiayannone A Description
||The herbs of Rubia yunnanensis Diels
|Biological Activity or Inhibitors:
|| 1. Rubiayannone A may have antiplatelet aggregation activity.
||DMSO, Pyridine, Methanol, Ethanol, etc.
||Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
Need more advice on solubility, usage and handling? Please email to: email@example.com
||The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

|Constituents from Rubia Ustulata Diels and R. Yunnanensis Diels and Their Antiplatelet Aggregation Activity[Reference: WebLink]|
|A new anthraquinone glycoside, Rubiayannone A (1), and a new coumarin, rubilatin-A (2), together with twenty-two known compounds were isolated and characterized from the roots of Rubia ustulata. A new anthraquinone, 2-carbomethoxyanthraquinone (3), and rubiayannone-A, 2-formylanthraquinone were obtained from the roots of R. yunnanensis. The structures of those compounds were elucidated by
spectroscopic methods. The antiplatelet aggregation activity of the isolated compounds 1, 4～6 were also discussed.
