Tóm tắt

Dicranopteris linearis (Burm. F.) Underw. has many popular traditional uses in Asian countries, such as treating ulcers and boils, allergic symptoms, or respiratory troubles. This study investigated the phytochemical of D. linearis grown in Lam Dong Province. The leaf powder of D. linearis was used to prepare a crude extract. This extract was then applied to the liquid-liquid partition to give different polar fractions. The EA fraction was thus applied to silica gel column chromatography to obtain four compounds. Their chemical structures were elucidated by using Nuclear Magnetic Resonance spectroscopy, as well as by the comparison of their NMR data with reported ones. Four compounds consisted of three flavonols, isoquercetin (1), quercetin (2), kaempferol (3), and a sterol, stigmast-5,22-dien-3β-ol-3-O-β-D-glucopyranoside (4).
