gamma-sitosterol and baicalin

To select the optimal combination of five active component of Banxia Xiexin Decoction on gastric ulcer rat, and observe its effect on Leptin and ET-1.. Eighty-seven SD rats were randomly divided into normal group, sham-operated group and acetic acid-induced gastric ulcer group, omeprazole group as a positive control, five active components (glycyrrhetic acid, beta-sitosterol, berberine, baicalin and ginsenoside) of Banxia Xiexin Decoction were divided into groups by L16 orthogonal design. The ulcer area, and the content of Leptin and ET-1, and the mRNA expression level of both were detected.. Among the sixteen orthogonal design groups, the ulcer area of these groups using both beta-sitosterol and berberine was the smallest (P < 0.05), the content of Leptin of these groups using both glycyrrhetic acid and ginsenoside was the highest in blood serum (P < 0.05), the group using glycyrrhetic acid had the minimum concentration of ET-1 in blood plasma. Compared with model group, berberine could raise the mRNA expression level of Leptin (P < 0.01), and beta-sitosterol could lower the mRNA expression level of ET-1 (P < 0.01).. The pathogenesis of gastric ulcer may be related with the down-regulation of concentration and mRNA expression level of Leptin, and upregulation of concentration and mRNA expression level of ET-1, the active components in Banxia Xiexin Decoction may upregulated Leptin and inhibit ET-1 to accelerate the healing of gastric ulcer.
