Abstract:
Seven new compounds, known as polygonatine N1‒N7 (1‒7), and a known compound (8) were isolated from the ‘Nine-Steam-Nine-Bask’ processing product of Polygonatum cyrtonema Hua. The compounds’ structures were determined by spectroscopic analysis. All compounds were tested for dipeptidyl peptidase-4 (DPP-4) inhibition, glucose transport, and anti-inflammatory activities. Compound 8 suppressed NO production with an IC50 of 35.4 μM.
