%X Four new constituents, as c is-6-oxogeran-4-enyl-10-oxy- O-汕-arabinopyranosyl-4∩- O-汕-arabinopyranosyl-2∩∩-octadec-9∩∩∩,12∩∩∩,15∩∩∩-trienoate ( 1), geran-3(10)-enyl-1-oxy- O-汕-arabinopyranosyl-4∩- O-汕-arabinopyranosyl-2∩∩-octadec-9∩∩∩,12∩∩∩,15∩∩∩-trienoate ( 2), geranilan-8-oxy- O- 汐-d-xylopyranosyl-2∩- n-octadec-9∩∩,12∩∩,15∩∩-trienoate ( 3), 1-cyclohex-2∩, 5∩-dienyl 1-cyclohexylethanol- O-汕-d-xylopyranoside ( 4), along with six known constituents, guaiacol- O-汕-d-arabinopyaranoside ( 5), n-tetradecanyl oleate ( 6), oleyl- O-汕-d-xyloside ( 7), n-octadec-9,12-dienoyl- O-汕-d-arabinopyranoside ( 8), linolenyl- O-汕-d-arabinofuranoside ( 9) andglyceryl-1,3-dipalmito-2-olein ( 10), were isolated and identified from the Dendropanax morbifera bark. The new structures were established by one-and two-dimensional NMR (and in combination with IR, FAB-MSand HR-ESI-FTMS. The comparative evaluation of antioxidant potential by phosphomolybdenum, DPPH, FRAP and the NO assay of four different compounds ( 1每 4), we have found that the compounds 1 and 2 have power as a natural antioxidant, whereas the compound 3 and 4 exhibited mild activity in comparison to compounds 1 and 2
