Abstract

Abstract: Ethnopharmacological relevance: Semen Arecae (SA) is one of the most commonly used Traditional Chinese Medicine. Charred Semen Arecae (CSA) is the processed product of SA. Alkaloids are considered as pharmacological mechanisms of SA and CSA on gastrointestinal motility. Recent studies have shown alkaloids decreased quickly after procession. However, the promoting on gastrointestinal motility were not decreased. Is gastrointestinal motility related to alkaloids of CSA? This study explored the effects of SA, CSA, Semen Arecae-Removal (SA-R), and Charred Semen Arecae-Removal (CSA-R) on gastrointestinal motility, Gastric Inhibitory Polypeptide (GIP), Glucagon Like Peptide-1 (GLP-1), gastric juice and bile in rats. Material and methods: Rats were randomly divided into six groups, including the Control group, SA group, CSA group, SA-R group, CSA-R group, and Positive drug group (Mosapride). Alkaloids of samples were knocked out by using the "target constituent removal" strategy. Gastric residue and intestinal propulsion rate were evaluated in rats. Serum levels of GIP and GLP-1 were measured by Enzyme-Linked Immunosorbent Assay (ELISA). Gastric juice and bile were examined, respectively. Results: CSA-R and SA-R have been investigated by the Preparative Thin-layer Chromatography (PTLC) method. Intestinal propulsion and gastric residue assessments confirmed the effectiveness of CSA and CSA-R. CSA-R was higher than SA-R in the GLP-1, pepsin activity, the secretion of bile, Bilirubin (BIL), and Cholesterol (CHO). The statistical comparison demonstrated that there is no difference between the CSA group and CSA-R group. Conclusions: After processing, the promoting gastrointestinal motility might be not related to alkaloids. Maillard reaction could be produced to promote the secretion of GLP-1, bile, and CHO for gastrointestinal motility. Our findings provide a pharmacological reference for the clinical application of SA and CSA in the treatment of digestive diseases. Graphical abstract: Image 1
