Methods Male ICR mice were randomly divided into 12 groups: control group, model group, omeprazole (4 mg·kg-1) group, GLSE low, medium and high dose (0.2, 0.4, 0.8 g·kg-1) groups, BGLS low, medium and high dose (0.6, 1.2, 2.4 g·kg-1) groups, GLSO low, medium and high dose (0.2, 0.4, 0.8 g·kg-1) groups, 20 in each group. Mice in control group and model group were given the same volume of normal saline. After seven days of continuous administration, ten mice in each group were randomly selected, except the control group, to establish acute gastric ulcer model intragastrically with anhydrous ethanol (10 mL·kg-1), and the samples were taken 1.5 h later. Each group of the remaining 10 mice ig indomethacin (40 mg·kg-1) to establish acute gastric ulcer models, the samples were collected after threehours. The general condition, gastric bleeding and ulcer of mice were observed, and the gastric injury score was performed, and the injury inhibition rate and injury incidence rate were calculated. Results There was no abnormality during administration in each group. After the mice were given anhydrous ethanol, the model group and omeprazole group began to show symptoms such as slowed movement, uncoordinated limb activity, deep breathing and slow frequency ten min later, while the mice given GLSO, BGLS and GLSE began to show symptoms 30 min later. The autonomic activity of indomethacin-induced model mice decreased in each group, and there was no difference among the groups. The behavior of mice in control group was as usual. Compared with control group, the gastric ulcer was induced by anhydrous ethanol and indomethacin intragastrically, and the gastric injury score was significantly increased (P < 0.01), and the injury rate was 100%. Compared with model group, preventive give GLSO, BGLS and GLSE can obviously reduce the bleeding or ulcer and gastric mucosa injury, stomach injury score significantly reduced (P < 0.01), the inhibition rate of damage increased significantly (P < 0.01), the injury rate was significantly reduced, in high dose group of GLSE, BGLS group and GLSO group. Conclusion BGLS and GLSE could suppress the formation of acute gastric ulcer in mice and the protective effect of GLSO on acute gastric ulcer was the best, followed by BGLS, and against significantly the alcoholic gastric ulcer."/>
