| Description: |
Ginsenoside Rk1 has anti-tumor, and anti-platelet aggregation
activities. Ginsenoside Rk1 can strongly inhibit permeability induced by VEGF, advance glycation end-product, thrombin, or histamine in human retinal endothelial cells, it reduces the vessel leakiness of retina in a diabetic mouse model; this anti-permeability activity of Rk1 is correlated with enhanced stability and positioning of tight junction proteins at the boundary between cells; Rk1 induces phosphorylation of myosin light chain and cortactin, which are critical regulators for the formation of the cortical actin ring structure and endothelial barrier. |
| Targets: |
VEGFR |
| In vitro: |
| Arch Pharm Res. 2002 Aug;25(4):428-32. | | Three new dammarane glycosides from heat processed ginseng.[Pubmed: 12214849] | Three new dammarane glycosides were isolated from the processed ginseng (SG; Sun Ginseng).
METHODS AND RESULTS:
Their structure were determined to be 3beta,12beta-dihydroxydammar-20(21),24-diene-3-O-beta-D-glucopyranosyl(1 --> 2)-beta-D-glucopyranoside; 3beta,12beta-dihydroxydammar-20(21),24-diene-3-O-beta-D- glucopyranoside and 3beta,6alpha,12beta-trihydroxydammar-20(21),24-diene-6-O-beta-D-glucopyranoside based on spectroscopic evidences.
CONCLUSIONS:
The compounds were named as Ginsenoside Rk1, Ginsenoside Rk2, and ginsenoside Rk3 respectively. |

Ginsenoside Rk2 Description
| Source: |
The roots of Panax ginseng C. A. Mey. |
| Solvent: |
DMSO, Pyridine, Methanol, Ethanol, 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.

| 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. |
