Effect of n-hexane leaf extract of Ipomoea batatas L. on the liver. (1) The control Rat liver composed of A—central vein, B—hepatocytes and C—sinusoids, (2) Rat liver treated with phenylhydrazine alone showed A—patchy vascular intimal ulceration, (3) rat liver treated with 5 mg/kg of ferrous (iii) hydroxide poly-maltose showed A—moderate vascular congestion, (4) at 125 mg/kg n-hexane extract showed mild vascular congestion (5) at 250 mg/kg n-hexane showed A—mild vascular congestion and (6) at 500 mg/kg n-hexane extract showed A-normal liver architecture (H&E × 100) of hepatocytes. They were using haematoxylin–eosin dye with X 40 magnification
