Jatropha Curcas Research, And The Chemical Composition Of Black Bone Vine

This paper mainly described the study on the chemical constituents of the leaves of Jatropha curcas L. and Marsdenia tenacissima (Roxb). Wight et Am. Sixteen compounds were obtained from the two plants by the means of traditional phytochemical methods. Among them, the structures of fifteen compounds were characterized by IR, ¹H NMR, ¹³C NMR and MS spectral data.Part one, from the leaves of Jatropha cureas L., ten compounds were isolated and identified as 4,14-dimethylheptadecane(MYS-1), 1-(pentadecyloxy) pentadecane (MYS-2), methyl palmitate (MYS-3), nonacosyl formate (MYS-4), ethyl palmitate (MYS-5), palmitic acid (MYS-6), stearic acid (MYS-7), stigmast-4-en-3-one (MYS-8),β-sitosterol (MYS-9), octacosane (MYL-10). Exceptβ-sitosterol (MYS-9), all compounds were isolated for the first time from the plant.Part two, from Marsdenia tenacissima (Roxb). Wight et Am., six compounds were isolated and five of them were identified as hentriacontane (WS-1), docosanoic acid (WS-2), taraxasterol (WS-3), Stigmasterol (WS-4),β-sitosterol (WS-5). All of the identified compounds were isolated for the first time from Marsdenia tenacissima (Roxb). Wight et Am.
