摘要
Two new sesquiterpenoids,(1S,2R)-dihydroxycycloax-4(15)-ene(1),14-dehydroxyl daucucarotol(2),and one new rhamnofalane diterpenoid,2-hydroxy-3-dehydroxycaniojane(3),together with two known compounds,curcusone D(4) and curcusone C(5),were isolated from the roots of Jatropha curcas.The chemical structures of these compounds were established by chemical methods and extensive 1D-and 2D-NMR spectroscopic data analyses.
Two new sesquiterpenoids, （1S,2R）-dihydroxycycloax-4（15）-ene （1）, 14-dehydroxyl daucucarotol （2）, and one new rhamnofalane diterpenoid, 2-hydroxy-3-dehydroxycaniojane （3）, together with two known compounds, curcusone D （4） and curcusone C （5）, were isolated from the roots of Jatropha curcas. The chemical structures of these compounds were established by chemical methods and extensive 1D- and 2D-NMR spectroscopic data analyses.
