成熟黑加仑中主要的黄酮苷类化合物。Silvergiters Schwarze)、杨梅素3-β-D-吡喃葡萄糖苷、芦丁和异槲皮苷均为晶体结构。经薄层层析分析，证实了花青素和飞雀素的3-芦丁糖苷和3-糖苷的存在。然而，在新鲜浆果中没有检测到游离的类黄酮苷元。从纸上紫外光和纤维素薄层色谱图上分离得到主要荧光蓝组分，鉴定为1-O-咖啡基-β-D-吡喃葡萄糖苷。同时分离得到1-O-阿魏基和1-Op-香豆基-β-D-吡喃葡萄糖苷。黑加仑中的羟基肉桂-D-葡萄糖的存在似乎以前没有被认识到。
The major flavonol glycosides of ripe blackcurrants (Ribes nigrum cv. Silvergieters Schwarze), myricetin 3-beta-D-glucopyranoside, rutin, and isoquercitrin, have been isolated in crystalline form. Analysis by thin-layer chromatography confirmed the occurrence of the 3-rutinosides and 3-glucosides of cyanidin and delphinidin. No free flavonoid aglycones could, however, be detected in the fresh berries. The major constituent fluorescing blue under ultraviolet light on paper and cellulose thin-layer chromatograms, was isolated and characterized as 1-O-caffeyl-beta-D-glucopyranose. Also isolated were 1-O-ferulyl-and 1-Op-coumaryl-beta-D-glucopyranose. The occurrence fo hydroxycinnamyl-D-glucoses in blackcurrants does not appear to have been recognized previously.
