Summary: | •Three new phenylpropanoid glycosides were isolated from Magnolia obovata fruit.•Recovery effects on alloxan-induced islet damage in zebrafish were evaluated.•All compounds increased the size of injured pancreatic islets 0.60- to 1.14-fold.•The isolated phenylpropanoids increased the glucose absorption ability in zebrafish.
Investigation of phytochemicals from Magnolia obovata fruit led to the isolation of three novel phenylpropanoid glycosides: obovatoside A–C (1–3) and two known phenylpropanoids, syringin (4) and pavonisol (5). The structures of 1–5 were determined by NMR, HRMS, IR and CD spectroscopic analyses. All compounds were evaluated for their effects on recovery from alloxan-induced pancreatic islet damage in zebrafish. All compounds increased the size of the injured pancreatic islet from 0.60- to 1.14-fold. Compounds 1 and 3–5 significantly increased glucose absorption in zebrafish. |
