Advances in Phytochemistry and Modern Pharmacology of Saposhnikovia Divaricata (Turcz.) Schischk.

Saposhnikovia divaricata (Turcz.) Schischk (S. divaricata, Fangfeng) is a herb in the Apiaceae family, and its root has been used since the Western Han Dynasty (202 B.C.). Chromones and coumarins are the pharmacologically active substances in S. divaricata. Modern phytochemical and pharmacological studies have demonstrated their antipyretic, analgesic, anti-inflammatory, antioxidant, anti-tumor, and anticoagulant activities. Technological and analytical strategy theory advancements have yielded novel results; however, most investigations have been limited to the main active substances-chromones and coumarins. Hence, we reviewed studies related to the chemical composition and pharmacological activity of S. divaricata, analyzed the developing trends and challenges, and proposed that research should focus on components' synergistic effects. We also suggested that, the structure-effect relationship should be prioritized in advanced research.

Effect of intestinal function-recovering decoction on treatment of multiple organ dysfunction syndrome in rats.

OBJECTIVE: To analyze the effect of intestinal function-recovering decoction on multiple organ dysfunction syndrome in rats, and to investigate a novel solution to multiple organ dysfunction syndrome. METHODS: Multiple organ dysfunction syndrome was induced in 60 Sprague-Dawley rats by intestinal ischemia-reperfusion combined with cecal ligation and puncture. Then these rats were intragastrically administered physiological saline (group I, n=20), ampicillin (group II, n=20) or intestinal function-recovering decoction (group III, n=20). After treatment, serum malondialdehyde and superoxide dismutase levels were compared among three groups. Simultaneously, bacterial culture of various organ tissues was performed and bacterial and endotoxin translocation were observed. RESULTS: Compared with group I, serum malondialdehyde, alanine aminotransferase and aspartate aminotransferase levels were significantly decreased (all P<0.05) and serum superoxide dismutase level was significantly increased (P<0.05) in the group III. However, there were no significant differences in these indices between groups II and III (P>0.05). The rate of bacterial translocation in the groups II and III was significantly lower than in the group I (P<0.05), and no significant difference was observed between groups II and III (P>0.05). CONCLUSIONS: Intestinal function-recovering decoction can significantly reduce endotoxin and bacterial translocation and stabilize enteral oxidative-antioxidative balance.
