 [Major volatile components of the juice of American cranberry., Croteau, R.J., Fagerson, I.S., Journal of Food Science, vol.33(4), 1968, 386-389]
-"Cranberry juice is recommended for the prevention and treatment of urinary tract infections (including cystitis) and kidney disorders. It is rich in vitamine C and has been used against scurvy... Presently it is assumed that cranberry contains substances which prevent the adhesion of E.coli to bladder wall linings. If E.coli cannot adhere, there is no infection. Controlled clinical studies have demonstrated the efficacy of cranberry to treat bladder infections." \\
+Of the 35 odor-active compounds detected by applying AEDA on the liquid ectract of cranberry, highest FD factors showed terpinolene (piney, sweet), decanal (citrus, peel), benzoic acid (balsamic), heptan-3-one (strong fruity, green, fatty), octen-3-one (mushroom), and (2E)-nonenal (waxy, cucumber), and are considered most important odorants in cranberry fruit. The main contributors to the aroma of cranberry fruit are esters (ethyl acetate, methyl butyrate, ethyl butyrate, benzyl acetate, anisyl acetate), terpenes (p-cymene, terpinolene, alpha terpineol), aldehydes (hexanal, octanal, nonanal, 2E-nonenal), acids (acetic acid, butyric acid, 2-ethylhexanoic acid, nonanoic acid, cinnamic acid, palmitic acid), two lactones (gamma tridecalactone, delta tetradecalactone), one one sulfur-compund, and one sulfur-nitrogen compound (2-isopropylthiazole). Compounds with relatively low FD factors included linalool oxide (floral, woody), trans-anethole (herbaceous), phenylethanol (floral), and vanillin. \\

+Of the quantified compounds found with odor activity values (OAVs > 1) in four cultivars of cranberries (Early Black, Howes, Searles, and McFarlin), hexanal (OAV 27-60), pentanal (OAV 31-51), (E)-2-heptenal (OAV 17-66), (E)-2-hexenal (OAV 18-63), (E)-2-octenal (OAV 10-28), (E)-2-nonenal (OAV 8-77), ethyl 2-methylbutyrate (OAV 10-33), β-ionone (OAV 8-73), 2-methylbutyric acid (OAV 18-37), and octanal (OAV 4-24) contributed most to the aroma of cranberry. The Searles cultivar was highly correlated with the sensory descriptors “floral” and “fruity”, and the McFarlin cultivar was greatly related to the sensory descriptors “mellow” and “green and grass”. \\

+"A total of 400 mg of total flavonoids and phenolic compounds/l of sample was found in a freshly squeezed cranberry juice, which was distributed as about 44% of phenolic acids and 56% of flavonoids. Benzoic acid was the major phenolic compound. Major flavonoids in the freshly squeezed cranberry juice were quercetin and myricetin." \\

+"Ethyl acetate extracts of Sephadex LH20-purified proanthocyanidins of American cranberry (Vaccinium macrocarpon Ait.) exhibited potent biological activity by inhibiting adherence of uropathogenic isolates of P-fimbriated Escherichia coli bacteria to cellular surfaces containing α-Gal(1 → 4)β-Gal receptor sequences similar to those on epithelial cells in the urinary tract. The chemical structures of the proanthocyanidins were determined by NMR, electrospray mass spectrometry, matrix-assisted laser absorption time-of-flight mass spectrometry and by acid catalyzed degradation with phloroglucinol. The proanthocyanidin molecules consisted predominantly of epicatechin units with mainly DP of 4 and 5 containing at least one A-type linkage. The procyanidin A2 was the most common terminating unit occurring about four times as frequently as the epicatechin monomer." \\
