Procyanidin A2 is a natural flavanol dimer of (-)-epicatechin that is found in the horse chestnut (A. hippocastanum), mountain cranberry (V. vitis-idaea), and other fruits with antioxidant, anti-inflammatory, antibacterial, antiproliferative, and antidiabetic properties. It scavenges 2,2-diphenyl-1-picrylhydrazyl radicals (IC50 = 5.08 μM) and inhibits STAT3 activation induced by platelet derived growth factor (PDGF) in primary rat vascular smooth muscle cells (VSMCs) when used at a concentration of 30 μg/ml. Procyanidin A2 inhibits growth of S. aureus and E. coli (MICs = 62.5 and 62.5 μg/ml, respectively) and proliferation of human HepG2 liver hepatocellular carcinoma and HeLa cervical cancer cells (EC50s = 62.19 and 66.07 μg/ml, respectively). It also increases insulin secretion from primary mouse pancreatic islets when used at a concentration of 10 μM in vitro and inhibits bisphenol A-induced glucose increases in fasted mice when administered at a dose of 10 μmol/kg per day.

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
