    Abstract:
    OBJECTIVE: To identify the chemical components and their relative content in seeds oil from Croton tiglium. METHODS: The oil obtained by extracting of the seeds of Croton tiglium with petroleum ether was subjected to methyl-esterification or dilution with ethylether. GC-MS were used to identify the components in croton oil,peak area normalization method was used to determine the relative content of these substances in the sample. RESULTS: Seventeen fat acid components were identified from croton oil. The main components were linoleic acid, oleic acid, and eicosenoic acid in methyl-esterified sample, whose quantities accouted for 77.33%. In addition, five aromatic compounds were also found in the sample diluted with ethylether, such as isoborneol, fenchyl alcohol, etc. Phorbol esters, having carcinogenesis and anti-HIV-1 effects, were not been identified. CONCLUSION: There are abundant of linoleic acid, oleic acid and eicosenoic acid in the seeds oil extracted from Chinese Croton tiglium. In contrast, the active component with carcinogenesis and anti-HIV-1 might be very rare in the samples and difficult to be obtained by ordinary separating and extracting methods.
