Test Method:


HPLC method

This method determines the content of each monomer, oligomer, and homopolymer in the extract. However, due to the limitations of the control and the analytical means, only the content of monomers and some oligomers in grape seed extracts can be determined. In practice, it is sufficient to determine the content of only those monomers. The main monomers in grape seed extracts are catechin, epicatechin, gallic acid, and epicatechin gallate. [5]

The content of monomers in grape seed extracts is generally around 10.0% and can reach up to 30.0%. Due to the complexity of grape seed extract components, it is generally difficult to completely separate multiple monomers by the HPLC method if the sample is not pretreated. Therefore, the extracts need to be pretreated to remove the polymers and improve the monomer content before injection. Commonly used pretreatment methods are silica gel column chromatography, SephadexLH- 20, Sephadex G25, Toyopeah TSK HW40, and other column chromatography methods. The sample can also be pretreated by thin-layer chromatography, generally using toluene: acetone: acetic acid = 3 : 3: 1 (V/V/V) as the unfolding agent.
