摘要
从蓝桉果实乙醇提取物的乙酸乙酯部位分离得到7个五环三萜化合物,经理化和波谱分析鉴定为3β-乙酰基-乌索-11,12-烯-28,13β内酯(1)、桦木酮酸(2)、白桦脂酸(3)、2α-羟基白桦脂酸(4)、2α,3β-二羟基乌苏-12-烯-28-酸(5)、熊果酸(6)、3β-羟基-乌索-11,12-烯-28,13β内酯(7),其中化合物1,4,5和7系首次从该植物中分离得到。
Seven pentacyclic triterpenes were isolated from the acetyl acetate fraction of the ethanol extract of Eucalyptus globulus Labill. fruits, and their structures were elucidated by physicochemical properties and spectroscopic analysis as 3β-acetoxyurs-11-en-28,13-olide （1）,betulonic acid （2）,betulinic acid （3） ,alphitolic acid （4） ,2α,3β-dihydroxyurs- 12-en-28-oic acid （ 5）, ursolic acid （ 6）, and 11,12-dehydroursolic acid lactone （7）. Compounds 1,4,5 and 7 were isolated from the plant for the first time.
