.The b-myrcene was also endowed
with marked enhancement of antioxidant enzyme activity from GR system as evidenced by the decreased activity of superoxide dismutase (SoD) and increased levels of glutathione peroxidase (GPx), glutathione reductase (GR), and total glutathione in gastric tissue. Our results also shown that treatment with B-myrcene is not involved with thioredoxin reductase (TrxR) activity. Our results reveal for the first time, the importance of b- Mycenae as an inhibitor of gastric and duodenal ulcers and demonstrate that an increase in the levels of gastric mucosa defence factors is involved in the anti-ulcer activity of B-myrcene.
