چکیده
2,3-Secofernane triterpenoids, alstonic acids A (1) and B (2), were isolated from the leaves of Alstonia scholaris together with an indole alkaloid, N(1)-methoxymethyl picrinine (3). Their structures were established from MS and NMR spectroscopic analyses and confirmed by single crystal X-ray diffraction analysis.

متن کاملQuinine and Alstonia Scholaris (Chhatim) in Malaria
Recent work has shown that Alstonia scholaris has little or no antimalarial action on Plasmodia of birds (Goodson, Henry and Macfie, 1930 ; Buttle, cited by Sharp, 1934), monkeys and man (Mukerji, Ghosh and Siddons, 1942). These findings do not bear out those of earlier workers in the treatment of fevers believed to be of malarial origin. It was claimed that the alkaloids of Alstonia were more ...
