Does grape seed extract contain flavan-3-ols?

In this review we follow a specific grape seed extract containing monomeric and oligomeric flavan-3-ols from its creation by Jack Masquelier in 1947 towards a botanical remedy and nutraceutical with proven health benefits.

How is Masquelier's grape seed preparation standardized?

Ad 1) In contrast to many commercially plant extracts Masquelier¡¯s grape seed preparation is rigidly defined and standardized by HPLC and 1 H-NMR/PCA fingerprinting. This combination of methods is optimal for monitoring the quality of plant extracts and is superior to the analysis of one or more individual ¡°target¡± components of an extract.

What are Masquelier's grape seed extract batches?

This cluster of Masquelier`s grape seed extract batches (Anthogenol?, yellow) clearly distinguishes from the cluster of French pine bark extracts (M-PM, red) and other grape seed extracts (GSEs, magenta).

What is the total polyphenolic content of Masquelier's grape seed extract?

By means of the reference polyphenol gallic acid total polyphenolics are quantified as gallic acid equivalents (GAE) per kg or liter extract. As shown in Table 2 the total polyphenolic content of Masquelier¡¯s grape seed extract amounts to 90¨C95% according to spectrophotometry and the Folin-Ciocalteau method.
