Objective:
To analyze the bioactive components in Jatropha curcas leaves using gas chromatography-mass spectrometry (GC-MS).
Methods:
The bioactive components were extracted from J. curcas leaves by supercritical fluid CO2 extraction and analyzed by using GC-MS.
Results:
Seventy peaks were detected by GC-MS, and 43 compounds were identified (61.43%). Among the identified compounds, 16 had a content of more than 1%, and the total contents of these 16 compounds reached 81.36%. The four most abundant components were 22,23-dihydro-stigmasterol (16.14%), alpha-tocopherol (15.18%), beta-amylin (7.73%) and dotriacontanol (7.02%). The content of gamma-tocopherol reached 2.88% and vitamin E reached 18.06% in the extract.
Conclusion:
J. curcas leaves contain multiple compounds with anti-tumor, anti-virus and antimicrobial activities.

Gas Chromatography: Introduction
In GC, a sample is vaporized and mixed with an inert carrier gas (the mobile phase), which transports it through a column.
Chromatography: Introduction
The phase in which the compounds linger or on which the compounds adsorb is called the stationary phase, whereas the mobile phase is the solvent that carries the solutes to be analyzed. In traditional column chromatography, the mixture flows through the stationary phase, and the compounds partition between the stationary and mobile phases...
