OPC exists in practically every plant and can be extracted from many vegetable sources. The study of 500 different types of plants demonstrates that flavanols are spread widely throughout the plant kingdom. They are found in ligneous sections (bark), in the fruit (peels and skin), in the groundnuts (skin), in the seeds (skin) and in the leaves and blossoms of woody plants (trees and shrubs). Masquelier developed extraction methods whereby OPC can be produced from virtually every plant. Still, the ways in which Masquelier has been striking an efficient balance between laboratory, scientific knowledge and the economical realities of agriculture and industry, show that one cannot just pick a plant that pleases the dreaming mind.
In terms of the availability and manageability of raw materials, it has become evident that pine bark and grape-seeds are reliable and industrially process able sources of OPC. Both sources give a high yield. We cannot rule out the effects of climate and since OPC is retrieved from “leftovers” (bark and seeds) one is also dependent on the methods of cultivation and harvesting. For the lumber and paper industry, pine trees are being chopped down earlier and earlier during their growth. Older trees have thicker bark than young trees, but they appear less and less in the forest. This can mean that in the long run pine bark might become a less feasible source for the extraction of OPC. Buy Masqueliers OPC. Lowest price on the internet.
