Figure 2From: Steam-cooking rapidly destroys and reverses onion-induced antiplatelet activity Mean polyphenolic concentration (by Folin-Ciocalteu’s procedure) of six onion extracts. The concentration was expressed as mg/ml of gallic acid equivalents shown on the left side. No significant change in GAE was detected (P = 0.147). Platelet aggregation was significantly different among extracts.Back to article page
