THE SESQUITERPENOIDS FROM CELASTRUS FLAGELLARIS

A new sesquiterpenoid(1) named as celastrine B along with seven known compounds 1α,6β,13-triacetoxy-9β-benzoyloxy-β-dihydroagarofuran(2), triptogelin G-1(3), 1α,6β-diacetoxy-9β-benzoyloxy-β-dihydroagarofuran(4), triptogelin F-2(5), 1α,2α-diacetoxy-9β-cinnamoyloxy-β-dihydroagarofuran(6), celaforlin B-3(7), 1α,6β-diacetoxy-8α-cinnamoyloxy-9α-benzoyloxy-β-dihydroagarofuran(8) were isolated for the first time from the seed oil of Celastrus flagellaris Rupr. and their structures elucidated by UV, IR, MS and ¹HNMR,¹³CNMR, DEPT,¹H-¹H COSY,¹³C-¹H COSY, NOESY and HMBC.
