AB  - On the basis of LC/UV/MS analysis, 35 compounds from the extracts of seeds of black, red, and white currants (2 cultivars of each) were identified. Black currants cultivars contained protocatechuic acid and p-hydroxybenzoic acid, and traces of nitril containing phenolic acids. The presence of synapoyl glucoside was characteristic for cv. Malling Jewel. Sesquiterpenoid glycosides and carboxymethylindol glycosides were present mainly in white and red currant cultivars. Blackcurrant seeds contained higher amounts of flavonoids, especially rutin, isoquercetin, and taxifolin. The currant seed extracts were tested for in vitro protective effect on chromosome aberrations in peripheral human lymphocytes using cytochalasin-B blocked micronucleus (CBMN) assay. The frequency of MN was scored in binucleated cells, and the cultivars of black currants showed the best antioxidant potential. At a concentration of only 0.17 mg/mL, extract of the seed cv. Malling Jewel effected a decrease in the frequency of MN of 60% compared with control cell cultures. Practical Application: Our results provide evidence of protective effects of currant seed extracts and isolated pure compounds on cytogenetic damages in human lymphocytes. Thus, currant seed extracts could exert beneficial effects in quite a few diseases, for many of the biological actions have been attributed to their antioxidant properties.

AB  - The tentative identification of seed extracts from 3 cultivars of blackberry (blackberry seed extracts [BSEs]) constituents was performed by LC/UV/MS technique. The identified compounds belonged to ellagitannins, galic acid derivatives, and ellagic acid derivatives. Two ellagitannins, Lambertianin C and Sanguiniin H-6, and an ellagic acid derivative, 4-alpha-L-arabinofuranosylellagic acid, were isolated using semipreparative High-performance liquid chromatography. The structure elucidations were based on high resolution-mass spectrometry and nuclear magnetic resonance studies. The BSEs and 3 isolated pure compounds were tested for in vitro protective effect on chromosome aberrations in peripheral human lymphocytes using cytochalasin-B blocked micronucleus (MN) assay. The frequency of MN was scored in binucleated cells, and nuclear proliferation index was calculated. Among the tested extracts, the seeds of cv. Thornfree at concentration of 1 mu g/mL exhibit the most prominent effect decreasing the frequency of MN by 62.4%, when compared with the controls cell cultures. Antioxidant potential of pure ellagitannins cannot explain the strong effect of BSEs. The assumption was that better antioxidant effect of BSEs result from synergistic effects of individual compounds contained in the extracts and/or some minor components possessed strong activity.

AB  - This study addresses in vitro effects of raspberry (Rubus idaeus) seed extracts (RSE) on the frequency of micronuclei. We evaluated the effects of three different extracts (50%, 80%, and 100% methanol) in doses of 1.4, 4.2, and 8.4 mu g/mL, per 5 mL culture using cytochalasin-B micronucleus (CBMN) assay in peripheral human lymphocytes. The frequency of MN was scored in binucleated (BN) cells. The nuclear proliferation index was also calculated. The distribution of polyphenolic compounds in RSEs was determined using LC/UV/ESI-TOF MS. The identified 37 compounds comprised flavanol monomers and oligomers, as well as varieties of ellagitannin components. Treatment of lymphocytes with RSEs induced a significant decrease in the frequency of micronuclei by 80%. These results demonstrate that the constituents of RSEs may be important in the prevention of oxidative lymphocyte damage by reactive oxygen species and may also reduce the level of DNA damage. These findings support the potential benefits of polyphenolic compounds from raspberry seeds as efficient antioxidants. (C) 2009 Elsevier Ltd. All rights reserved.

AB  - The distribution of polyphenolic compounds in a grape (Vitis vinifera) seed extract (GSE) was determined using LC/ESI-TOF MS, HPLC/DAD, and (13)C-NMR. The 17 identified compounds comprised gallic and protocatechuic acid, catetchin and epicatechin monomers, procyanidin oligomers, and procyanidin gallates. This study addresses the in vitro effects of grape seed extract (GSE) on the frequency of micronuclei with reference to the antioxidant status in human lymphocytes. To establish the most effective protective support, we used four different concentrations of GSE, in the range 1-6 mu g/mL. Treatment of lymphocytes with GSE at a concentration of 2.5 mu g/mL induced a significant decrease in the frequency of micronuclei by 40%, reduction of malonyldialdehyde production by 30%, while a concentration of 5 mu g/mL increased catalase and glutathione S-transferase activity by 10 % and 15 %, respectively. These results demonstrate that GSE may be effective in the prevention of oxidative lymphocyte damage by ROS.
