摘要
目的:研究银线草(Chloranthus japonicus)全株的化学成分;方法:利用各种色谱方法进行分离;通过各种光谱方法鉴定化合物结构;结果:从银线草分离得到1个新的倍半萜chlojaponilactoneA(1)和5个已知倍半萜:白术内酯III(2),neolitacumoneB(3),10α-hydroxy-1-oxoeremophila-7(11),8(9)-diene-8,12-olide(4),银线草内酯C(5)和银线草内酯H(6);结论:chlojaponilactoneA(1)为新的桉烷型倍半萜内酯,化合物3和4首次从该植物中分离得到。
AIM： To study the chemical constituents of the whole plant of Chloranthusjaponicus. METHODS： Compounds were isolated and purified by column chromatography. Their structures were elucidated on the basis of spectroscopic methods. RESULTS： Six sesquiterpenoids were obtained and their structures were identified as chlojaponilactone A （1）, atractylenolide III （2）, neolitacumone B （3）, 10a-hydroxy-l-oxoeremophila-7（11）, 8（9）-diene-8, 12-olide （4）, shizukanolide C （5）, and shizukanolide H （6）. CONCLUSION： Compound 1 is a new eudesmane-type sesquiterpenoid lactone, and compounds 3 and 4 have been isolated from this species for the first time.
