Abstract
Phytochemical investigation on the aqueous extract from Dryopteris fragrans led to the isolation of one new chromone glycoside, frachromone C (1), and one new coumarin glycoside, dryofracoulin A (2), together with one known undulatoside A (3). Their structures were elucidated by a combination of 1D and 2D NMR, HRMS, and chemical analysis. Compounds 1-3 exhibited inhibition on nitric oxide production in lipopolysaccharide induced RAW 264.7 macrophages with their IC50 values of 45.8, 65.8, and 49.8 μM, respectively.Entities:
