The Field Of Efficacy Of Grape Seed Extract
Apr 26, 2019

Here I'd like to mention a few noun symbols related to Grape seed extract. Many friends often ask me about GSP, Grape seed polyphenols, GSPE, Grape seed proanthocyanidins extract, OPC, Oligomer proanthocyanidins, PPC, Polymer proanthocyanidins.

The proanthocyanidins and resveratrol in grapes belong to polyphenols, which have strong antioxidant capacity and have strong preventive and protective effects on cardiovascular diseases. In addition in the anti - cancer, anti - inflammatory, skin health and beauty have very good results.


OPC proanthocyanidin is a kind of biological flavonoid with special molecular structure. The basic nucleotide of OPC is c6-c3-c6 structure, represented by flavanols. Because of the class material molecules have more similar units, even if the degree of polymerization is also very similar with different properties, and often with a variety of isomers of degree of polymerization, even exists because of the connection between monomer key free spin up and conformation, chiral isomers, makes scientific research workers in nuclear magnetic resonance (NMR) spectrum in difficulties. Therefore, it is generally called oligomeric proanthocyanidins (OPC) below pentameric, and high or poly proanthocyanidins (PPC) above pentameric.

On the other side, cyanidin and procyanidin. Anthocyanin is a pigment found in the petals and fruits of plants, such as the familiar colors of cranberries, blueberries and blackcurrants. The pigment changes color with the PH. Proanthocyanidins PCA is a large class of polyphenol bioflavonoids, which is composed of a series of macromolecules and small molecules. Catechins and proanthocyanidins OPC are both part of PCA. So the grape seed extract has procyanidins, procyanidins, no anthocyanins.


Welcome colleagues in plant extraction industry or friends in related industries to discuss plant extraction industry knowledge and information together!


I hope you are happy, it is not because of me, love you!
