Abstract: A process for selectively extracting cocoa procyanidins from an aqueous mixture of cocoa polyphenols, by using a particular sequence of acetate solvents and/or diethyl ether solvents to extract selected desired procyanidin monomers and/or oligomers. The aqueous mixture of cocoa polyphenols is first extracted with n-butyl acetate. The acetate solvents include n-butyl acetate, ethyl acetate and methyl acetate. The diethyl ether solvents include mixtures of methyl acetate and diethyl ether in the following ratios (methyl acetate:diethyl ether): 0:100, 25:75, 75:25 (all v/v).

Abstract: An improved process for separating and isolating individual polar protic monomer(s) and/or oligomer(s) on the basis of degree of polymerization. A liquid sample containing polar protic monomer(s) and/or oligomer(s) is introduced into a liquid chromatography (LC) column packed with a polar bonded stationary chromatographic phase. The individual polar protic monomer(s) and/or oligomer(s) are separated via a binary mobile phase elution. One or more individual fractions containing the monomer(s) and/or oligomer(s) are eluted. The polar protic monomer(s) and/or oligomer(s) may be proanthocyanidins, hydrolyzable tannins, oligosaccharides, oligonucleotides, peptides, acrylamides, polysorbates, polyketides, poloxamers, polyethylene glycols, polyoxyethylene alcohols or polyvinyl alcohols. The binary mobile phase comprises an A phase consisting essentially of a polar aprotic solvent and a B phase consisting essentially of a polar protic solvent. A process for separating and isolating xanthine(s) (e.g.

Abstract: The invention relates to compositions, and methods of use thereof, containing polyphenols such as flavanols, procyanidins, their derivatives and epimers thereof, for inducing peripheral blood vessel vasodilation, for example for treating or preventing peripheral vascular diseases.

Abstract: The invention relates to compositions containing derivatized flavanols such as methylated flavanols, and methods of use thereof for prophylactic or therapeutic treatment of a human or a veterinary animal for example as anti-platelet agents.

Abstract: The invention relates to compositions, such as pharmaceuticals, foods, food additives, or dietary supplements, containing dimer digallates, and methods of use thereof, for prophylactic or therapeutic treatment of a human or a veterinary animal to treat or prevent NO-responsive health conditions, treat hypertension, cardiovascular disease, coronary artery disease, diabetes, cognitive dysfunction or disorder and/or vascular circulation disorders, prevent or reduce the risk of heart attack, stroke, congestive heart failure and/or kidney failure, or to improve blood flow, for example renal blood flow. The composition may optionally contain an additional NO modulating agent and/or a vascular-protective or therapeutic agent, or may be administered in combination with such an agent.
