Table 2 Estimation of plant extraction yield, total phenolics, flavonoids, antioxidant capacity and reducing power of Alnus nitida bark

From: Phytochemical, antioxidant and hepatoprotective effects of Alnus nitida bark in carbon tetrachloride challenged Sprague Dawley rats

Sample Yield (g)* Total phenolic contents expressed as gallic acid equivalents (mg/g of extract) Total flavonoid contents expressed as rutin equivalents (mg/g of extract) Total antioxidant capacity expressed as ascorbic acid equivalents (mg/g of extract) Total reducing power expressed as ascorbic acid equivalents (mg/g of extract)
