| Abstract: | A pair of epimers were isolated from Celastrus flagellaris Rupr,for the first time,their chemical structures were elucidatcd as 1α,6β,8α,13-tetraacetoxy-9α-benzoyloxy-β-dihydroagarofuran(1) and lα,6β,8α,13-tetraacetoxy-9β-benzoyloxy-β-dihydroagarofuran(2) mainly by 1H-1H COSY,13C-1H COSY,NOESY and HMBC spectra.Compound 1 is a new compound named as Celastrine. |
