However, specific in vivo efficacy studies, including pharmacokinetic and pharmacodynamic parameters, have not been detailed in the available sources. Further research is needed to fully characterize its in vivo activity and therapeutic potential.
|
| Enzyme Assay |
For cell-free assays, the ACE inhibitory activity of Ginsenoside Ra2 can be measured using a standard ACE activity assay. The compound is incubated with purified ACE enzyme and a fluorogenic or chromogenic substrate (e.g., Abz-Gly-p-nitro-Phe-Pro-OH). The rate of substrate cleavage is monitored fluorometrically or spectrophotometrically. The IC50 value is calculated from a dose-response curve.
|
| Cell Assay |
For in vitro cellular assays, the ACE inhibitory activity of Ginsenoside Ra2 can be assessed in cells expressing ACE. Cells are treated with various concentrations of the compound, and ACE activity is measured using a substrate. The IC50 for ACE inhibition is calculated from dose-response curves.
|
| Animal Protocol |
For in vivo studies, Ginsenoside Ra2 could be administered orally in animal models of hypertension. Blood pressure is measured at various time points. Its effect on ACE activity in plasma or tissues can also be assessed.
|

Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).
