Ripe fruits of V. stamineum from seedlings of seeds collected from the wild in Florida and Georgia and grown in North Carolina, and from random population collections in western South Carolina were analyzed for total contents of anthocyanin (Acy) (7–101 mg/100 g) and flavonols (5–48 mg/100 g). Total Acy content was positively related to the intensity of surface coloration (white red to blue to purple). Neither Acy nor flavonol content was related to the geographic origin of the fruits, thus supporting the theory of common taxonomic classification. Three Acy were identified in these fruits, monoglycosides of the sugars galactose, arabinose, or glucose with the aglycone cyanidin. The monoglycosides of galactose and arabinose were found in all samples. The monoglycoside of glucose was found in trace amounts but was not found in all samples. Fruits of V. stamineum appear promising for introduction as a new crop or for incorporation into the breeding-program for commercial blueberries. |
