Effect of six Korean plants on glucagon like peptide-1 release

Glucagon like peptide-1 (GLP-1) plays a major role in the regulation of energy homeostasis as it causes satiety and suppresses appetite. Angelica dahurica, Coreanomecon hylomeconoides, Chrysanthemum morifolium, Portulaca oleracea, Stellaria alsine, and Stellaria media have traditionally been used as famine relief foods in Korea. The aim of the present study was to determine whether the aqueous ethanolic extracts of the six plants stimulate GLP-1 secretion. The results demonstrated that each extract of the plants stimulated GLP-1 secretion from enteroendocrine NCI-H716 cells, respectively. Among the extracts examined, the extract of Portulaca oleracea showed the highest activity on GLP-1 release. The results may suggest that the GLP-1 secretion induced by the six plants is a possible mechanism for the six plants exerting effects on satiety increase and appetite suppression.
