从南蛇藤种油中分离鉴定了六个 β 二氢沉香呋喃倍半萜 ,通过1HNMR ,13 CNMR和单晶X 射线衍射鉴定 ,它们的结构是 :1α ,6 β 二乙酰氧基 9β 苯甲酰氧基 β 二氢沉香呋喃 (1) ,1α,6 β 二乙酰氧基 9β 肉桂酰氧基 β 二氢沉香呋喃 (2 ) ,1α 乙酰氧基 6 β,9β 二苯甲酰氧基 β 二氢沉香呋喃 (3) ,1α ,2α 二乙酰氧基 9β 肉桂酰氧基 β 二氢沉香呋喃 (4) ,1α 羟基 2α 乙酰氧基 9β 肉桂酰氧基 β 二氢沉香呋喃 (5 )和 1α 乙酰氧基 2α羟基 9β 肉桂酰氧基 β 二氢沉香呋喃 (6 )。化合物 2 ,5和 6是首次从南蛇藤中分离得到。 Six β-dihydroarsenofuran sesquiterpenoids were isolated and identified from Celastrus species, and their structures were identified by 1HNMR, 13CNMR and single crystal X-ray diffraction. Their structures were: 1α, 6β diacetoxy 9β-benzoyl Acyloxy β dihydrobachen (1), 1α, 6 β diacetoxy 9β cinnamoyloxy β dihydrobachen (2), 1α acetoxy 6 β, 9β dibenzoyloxy β di Hydrocarbitol (3), 1α, 2α diacetoxy 9β-cinnamoyloxy β-dihydroarscanofuran (4), 1α hydroxy 2α-acetoxy 9β-cinnamoyloxy β-dihydroarscanofuran (5) and 1α acetyl Oxy 2α hydroxy 9β cinnamoyloxy β dihydrobenzofuran (6). Compounds 2, 5 and 6 were isolated from Celastrus oryzae for the first time.
