PEREIRA, B.S. et al. Hepatoprotective activity of hexane and ethanol extracts from Momordica charantia L. leaves. Rev. bras. plantas med. [online]. 2010, vol.12, n.3, pp.311-316. ISSN 1516-0572.  http://dx.doi.org/10.1590/S1516-05722010000300008.

Momordica charantia L. (Cucurbitaceae) has been used in folk medicine based on its several biological and pharmacological properties. The aim of this work was to evaluate the hepatoprotective activity of hexane (HE) and ethanol (EE) extracts from M. charantia leaves on the acute liver injury model induced by ethanol. Steroids were detected in both extracts, and EH had higher antioxidant activity than EE. Oral pretreatment of male Swiss mice for three consecutive days with 25, 50 or 100 mg kg-1 HE prevented the increase in AST and ALT (p<0.05), whereas pretreatment with EE only prevented ALT increase (p<0.05). Both extracts reduced the activity of hepatic enzymes; however, HE had a more relevant effect, characterizing hepatoprotective potential, likely associated with its antioxidant potential.

Palavras-chave : Momordica charantia; Cucurbitaceae; biomarkers; hepatic activity; ethanol.
