Comparative Histological Evaluation of the Fruit of Ribes nigrum and Ribes rubrum

/?-Carboline Alkaloids from Ribes nigrum L

From Ribes nigrum L. two ß-carboline alkaloids (deshydroxymethyl flazin (1) and flazin methyl ether (2)) could be isolated in minute amounts. The structure elucidation is described. The two compounds are present in the freshly pressed juice, but they are also formed during storage of the juice by condensation of tryptophane with ascorbic acid or its degradation products. This could be shown by ...

Detection of the polyphenolic components in Ribes nigrum L.

BACKGROUND The blackcurrant (Ribes nigrum L.) is a species of native currant which contains a lot of polyphenolic antioxidants which is used medicinally and has a fundamental role in the maintenance health. MATERIALS, METHODS AND OBJECTIVE: Ultraviolet-visible spectrophotometry and ultraviolet range high performance liquid chromatography (HPLC) were used to characterize the polyphenolic content...

BLACK CURRANT (Ribes nigrum L.) – AN INSIGHT INTO THE CROP

Black Currant (Ribes nigrum L.) and Bilberry (Vaccinium myrtillus L.) Fruit Juices Inhibit Adhesion of Asaia spp.

The aim of the study was to evaluate the activity of high-polyphenolic black currant (Ribes nigrum L.) and bilberry (Vaccinium myrtillus L.) juices against bacterial strains Asaia lannensis and Asaia bogorensis isolated as spoilage of commercial soft drinks. The composition of fruit juices was evaluated using chromatographic techniques HPLC and LC-MS. The adhesion to glass, polystyrene, and pol...
