| 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. |
