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. 

A novel cyclohexenone from Trachyspermum roxburghianum

Abstract A novel cyclohexenone, roxydienone (1), together with 13 known compounds (2–14), were isolated from the seeds of Trachyspermum roxburghianum. The structures of these compounds were

Plant-derived endoperoxides: structure, occurrence, and bioactivity

The present review summarizes the current knowledge about the structure, occurrence, peroxide detection methods, stability, biosynthesis, and biological activities of 206 endoperoxides isolated from 1911 to 2019, found in 115 plant species belonging to 36 different plant families.

Pervasive System Biology for Active Compound Valorization in Jatropha

In this chapter, the principal conceptual strategies that may be taken to valorize natural compounds in the genus Jatropha are reviewed.

Hydroxy-octadecenoic acids instead of phorbol esters are responsible for the Jatropha curcas kernel cake’s toxicity

Wang et al. report that an isomeric mixture of 3 hydroxy-octadecenoic acids, instead of widely recognised phorbol esters, are the major toxic component of Jatropha curcas kernel cake and elucidate the mechanism behind the toxicity, with a goal to help establish an environmentally friendlyJatropha biofuel industry.

Genome-wide analysis of the terpene synthase gene family in physic nut (Jatropha curcas L.) and functional identification of six terpene synthases

Eight among the 26 TPS-a genes showed expression in developing seeds of physic nut in the present study and may facilitate the efforts for identifying TPS genes involving the physic nut terpene synthesize.

Influence of bioenergy crop Jatropha curcas amendment on soil biogeochemistry in a tropical vertisol

Experiments were carried out to determine how the incorporation of biomass from the bioenergy crop Jatropha curcas into a tropical vertisol affects the biogeochemical processes important for

Effects of Planting Associated Wrinkled-Leaf Jatropha on the Growth and Fruiting of Inca Peanut

During 2012-2015 years, new Jatropha varieties and Inca peanut planting collocation experiment had been conducted on the south subtropical high-grade oil planting test bases of Xishuangbanna and

Effects of Planting Associated Wrinkled-Leaf Jatropha on the Growth and Fruiting of Inca Peanut

Experimental results show that after Inca peanut accompanied planting with wrinkled-leaf jatropha, in the planting test area the nematode and termite’s dangers had been greatly lower than those of Inca peanuts monoplanting.



Diterpenes, sesquiterpenes, and a sesquiterpene-coumarin conjugate from Jatropha integerrima.

Five new compounds and nine known compounds have been isolated from the roots of Jatropha integerrima and six diterpenes were evaluated for their antiplasmodial, antituberculosis, and cytotoxic activities.

A New Sesquiterpene from the Fruits of Daucus carota L.

To the authors' knowledge, compound 1 is the first example for a natural eudesmane sesquiterpene with a hydroxymethyl group located at a methine carbon rather than a usual quaternary carbon in the two fused six-membered ring systems.

Jatrophalactam, a novel diterpenoid lactam isolated from Jatropha curcas.

Jatrophalactam (1), a novel diterpenoid lactam possessing an unprecedented 5/13/3 tricyclic skeleton, was isolated from the roots of Jatropha curcas. The structure and relative configuration of

Spirocurcasone, a diterpenoid with a novel carbon skeleton from Jatropha curcas.

The stereostructure of spirocurcasone was established using HRESIMS, NMR, and quantum mechanical calculation of the electronic circular dichroic (ECD) spectrum.

Uncommon Sesquiterpenoids and New Triterpenoids from Jatropha neopauciflora (Euphorbiaceae)

Eight new terpenoids (1–8) were isolated from the bark of Jatropha neopauciflora, together with eight known compounds. The new isolates include the sesquiterpenoids (1R,2R)-diacetoxycycloax-4(15)-ene
