ResumoThe annual production of cranberries in the United States amounts to approximately 500,000 barrels, valued at 5 to 6 million dollars.Despite the economic importance of the American cranberry, Oxycoccus macrocarpus (Vaccinium moxrocarpon), it has received considerably less attention from a chemical view-point than has been accorded the cowberry, Vaccinium vitis id~cz, which serves in the northern European dietary much as the cranberry does in America.Wehmer (1) cites numerous instances of the identification of citric, malic, and benzoic acids in cranberries.Quinic acid, which was presumed by Blatherwick and Long (2) to be the precursor of hippuric acid secreted in the urine following ingestion of cranberries, was isolated from fresh berries by Kohman and Sanborn (3).The red pigment of the cranberry has been identified as 3+glucosidyl peonidin chloride by Grove and Robinson (4).The mineral constituents of the ash have been determined-by Morse (5), who also made comparative proximate analyses of a large number of cranberry varieties (6).He reported as wax the carbon tetrachloride extract of cranberries, and showed that this fraction increased during growth; for example, during the month of September from 0.40 to 0.47 per cent (fresh weight basis) and from 0.28 to 0.35 per cent for Early Black and Howes varieties, respectively.In view of the fact that most of the residue extracted from cranberry pomace with petroleum ether and ether originates from the surface of cranberries and because some of the substances might
