|Source:||The roots of Patrinia rupestris.|
|Biological Activity or Inhibitors:||1. Rupesin E shows significant antibacterial activities against Escherichia coli.
|Solvent:||Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.|
|Storage:||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.

|After receiving:||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.|

|Five new iridoids from Patrinia rupestris.[Pubmed: 17193308 ]|
|Five new iridoids, namely rupesin A, rupesin B, rupesin C, rupesin D, Rupesin E (1-5, resp.), together with six known iridoids, 6-11, were isolated from the roots of Patrinia rupestris. Their structures were elucidated by spectroscopic methods including IR, UV, MS, and 1D- and 2D-NMR experiments, and comparison with data of known analogues. Compounds 4 and 11, compounds 1, 2, 5(Rupesin E), 6, 8, 9, and 10, and compounds 3, 4, and 8 showed significant antibacterial activities against Bacillus subtilis, Escherichia coli, and Staphylococcus aureus, respectively.|
