# Moringa oleifera fruit extract as a potential antioxidant against liver injury by 2-Nitropropane induction in obese male mice model: pre-clinical study

## TL;DR

This study shows that Moringa oleifera fruit extract may help protect the liver from damage caused by a chemical in obese male mice.

## Contribution

The study demonstrates Moringa oleifera's antioxidant potential in a novel mouse model of liver injury.

## Key findings

- Moringa oleifera extract reduced oxidative stress markers like MDA and 8-OHdG in mice.
- The extract increased antioxidant levels such as GSH, catalase, and MnSOD.
- Liver enzymes SGPT and SGOT decreased, indicating reduced liver damage.

## Abstract

Background:
Moringa oleifera fruit extract contains beneficial chemical compounds. This study was conducted to observed the power of antioxidant against liver injury by 2-Nitropropane induction in an obese male mice model.

Methods: This research was
in vivo laboratory experimental study with a post-test control design group only. The population was obese male mice models, Swiss strain, aged 6–8 weeks, weighing between 60–80 gr. The research sample was determined by Federer's formula for a complete randomized design experimental test, group N (control), O1 (induced by 2-Nitropropane intraperitoneal (i.p) once), O2 (induced by 2-Nitropropane i.p twice), P1 (induced by 2-Nitropropane i.p. once and gavage with
M. oleifera fruit extract 500mg/kg bodyweight (BW) once a day), P2 (induced by 2-Nitropropane i.p. twice and gavage of
M. oleifera fruit extract 500mg/kg BW once a day), and P3 (induced by 2-Nitropropane i.p. twice and gavage of vitamin C 500mg/kg BW once a day). Antioxidant potential parameters were measured by levels of malondialdehide (MDA), glutation (GSH), 8-hydroxy-2'-deoxyguanosine (8-OHdG), catalase activity, manganese superoxide dismutase (MnSOD), serum glutamic pyruvic transaminase (SGPT), serum glutamic oxaloacetic transaminase (SGOT). This research was held at the Biochemistry laboratory of Medicine Faculty, UPN Veteran Jakarta in May–September 2020. Analysis was carried out using SPSS version 20.0. The parameters were tested using ANOVA.

Results: MDA levels decreased, GSH increased, 8-OHdG decreased, catalase activity increased, MnSOD activity increased and SGOT, SGPT levels decreased.
M. oleifera fruit extract was statistically proven to be a candidate for potential antioxidant against liver injury of 2-Nitropropane induction in obese male mice model.

Conclusions:
M. oleifera fruit extract was statistically evident as an antioxidant substance that reduces oxidative stress in acute liver injury caused by 2-Nitropropane induction.
