FOUR COMPOUNDS FROM DICRANOPTERIS LINEARIS SPORES

Dicranopteris linearis, a widely utilized plant species in traditional Vietnamese medicine, has been chemically investigated. Four compounds (1–4), including syringaresinol (1), shikimic acid (2), angelicin (3), and 3,4-dihydroxycinnamic acid (4) were isolated and structurally elucidated. Extensive spectroscopic methods were employed for structural elucidation. These isolates were subsequently evaluated for their alpha-glucosidase inhibitory activity and inhibitory effect on nitric oxide production in LPS-stimulated RAW 264.7 cells.Isolated compounds exhibited no inhibitory activity in either alpha-glucosidase or nitric oxide inhibition assays.
