Botanical collection produces edible berries about 1 cm in diameter differing (for different varieties) in color from greenish-yellow to shiny black. The four main anthocyanins are the same as for black currant fruits: delphinidin-3-glucoside, delphinidin-3-rutinoside, cyanidin-3-glucoside and cyanidin-3-rutinoside; the peaks assignment has been confirmed by spectropho-tometrical and mass spectrometrical detections. The overall anthocyanin accumulation depends upon fruit color intensity, differing in the broad range from 0.065 to 0.980 g cyaniding-3-glucoside chloride equivalent per 100 g of fresh fruits. Mode of anthocyanins biosynthesis in fruits of some species of Ribes genus is discussed on the basis of rela tive activity of corresponding enzymes. vol.% anthocy-anidine-3-rurinoside. on chromatograms) of four anthocyanins

The qualitative and quantitative compositions of anthocyans from fruit of plants of the Caprifoliaceae family grown under conditions of Belgorod region were investigated. The plants included elder species [Sambucus nigra L. (I), S. canadensis (II), and S. canadensis f. sceletoniana (III)], Viburnum opulus L., and Lonicera caerulea L. It has been found that the principal anthocyans of I are cyanidin-3-sambubioside (52.5%) and cyanidin-3-glucoside (37.1%) whereas from the other two elder species the principal component was cyanidin-3-sambubioside-5-glucoside, acylated p-coumaric acid, 70.9 (II) and 54.3% (III). Fruit of the other plants did not contain acylated anthocyans. The content of anthocyans in fresh or dried fruit was determined by spectrophotometry.
