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.
