Phytochemicals and Constituents of Ribes nigrum.:

Parts Used: The berries, seed oil, and leaves.In addition to the anthocyanin glycosides which are responsible for its color, black currant concentrate also contains sugars and acids (including citric acid) typical of fruits.

 Main content: Linoleic acid, ( GLA ) gama Linolenic acid and alpha Linoleic acid.Flavonoids (about 0.5%) are present, including derivatives of quercetin, kaempferol, myricetin, isorhamnetin and sakuranetin. Essential oil, 0.4% proanthocyanidins, diterpenes and ascorbic acid (0.3%) are reported to be present.

 Vitamins: Blackcurrant fruits are a good source of minerals and vitamins, especially vitamin C. They have diuretic and diaphoretic actions, help to increase bodily resistance to infections and are a valuable remedy for treating colds and flu. The juice, especially when fresh or vacuum-sealed, helps to stem diarrhoea and calms indigestion.

 GLA:The seed is a source of gamma-linolenic acid, an unsaturated fatty acid which assists the production of hormone-like substances. This process is commonly blocked in the body, causing disorders that affect the uterine muscles, nervous system and metabolism. We have no records of the oil from this species being used medicinally, though it is used in cosmetic preparations.

 Anthocyanosides: Black Currant is rich in anthocyanosides. Over 15 different anthocyanosides have been found in Black Currant. Anthocyanosides help to maintain the integrity of capillaries and to stabilize collagen. Anthocyanosides are also potent antioxidants. Numerous clinical studies have shown that Black Currant is effective in the treatment of circulation disorders, varicose veins, and other venous and arterial disorders. The anthocyanosides protect veins and arteries by stabilizing the phospholipids of the endothelial cells, and by increasing the synthesis of collagen and mucopolysaccharides which give the arterial walls their structural integrity. Antho-cyanosides also prevent the aggregation and adherence of platelets to endothelial surfaces. Studies have also shown that Black Currant can act as a coadjutant in heme-ralopy and diabetic retinopathy and can stimulate rhodopsin production.

 Nigrumin-5-p-coumarate and nigrumin-5-ferulate, two unusual nitrile-containing metabolites from black currant (Ribes nigrum) seed:

 Two novel nitrile-containing compounds, nigrumin-5-p-coumarate and nigrumin-5-ferulate, together with six known flavonoids, were isolated from the seed of black currant (Ribes nigrum). The chemical structures of nigrumin-5-p-coumarate and 5-ferulate were elucidated using NMR spectroscopy as 2-trans-p-coumaroyloxymethyl-4-beta-D-glucopyranosyloxy-2(E)-butenenitrile and 2-trans-feruloyloxymethyl-4-beta-D-glucopyranosyloxy-2(E)-butenenitrile, respectively.
