Abstract: | 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. |
