To study the effect of anthocyanin rich fruit extract on PGE2 produced by endothelial cells.


Normal human endothelial cells, CRL-2606, were cultured in F12K medium (complemented with 10% FBS, 0.1 mg/ml heparin, 0.03 mg/ml ECGS, 50 microg/ml streptomycin and 500U/ml penicillin) in 5% CO2 with 95% air at 37 degrees C. When the cells grow close to confluence, anthocyanin rich fruit extract with/without 100 ng/ml of LPS were added to the medium. After 18 hours of incubation, cells were harvested and the supernatant were collected. Cell viability was assayed. After centrifugation, PGE2 concentration in the supernatant was measured with the STAT-Prostaglandin E2 EIA Kit.


300 microg/ml or higher Chokeberry extract showed cytotoxicity effect on CRL-2606 cells, the viability was lower than 60% and showed a dose-response manner. Under using dosage, Blackcurrant extract (100 - 700 microg/ml) and Blueberry extract (50 - 400 microg/ml) did not show any cytotoxicity. When stimulated by LPS, the production of PGE2 by endothelial cells were increased two fold. Blueberry extract inhibit such action. 100 microg/ml of Blueberry extract keeps the production of PGE2 in normal level. 700 microg/mL of Blackcurrant extract and 500 microg/ml Chokeberry extract also inhibit the releasing of PGE2.


Anthocyanin rich fruit extract from Blueberry, Blackcurrant, and Chokeberry inhibit PGE2 produced by endothelial cells, there exist antiinflammation and antioxidation.
