Abstract: A new styryl-2-pyrone glucoside (1) and a known styryl-2-pyrone glucoside (2) , together with four other known compounds (3 - 6) , were isolated from the ethanol extract of the fern Brainea insignis . The structures of these compounds were determined by means of spectroscopic analysis including 1D and 2D NMR, HR-MS . And the capacities to scavenge against DPPH radical of two styryl-2-pyrone glucosides were assayed .
