Alstonic acids A and B, unusual 2,3-secofernane triterpenoids from Alstonia scholaris.[Pubmed:
19361823]
METHODS AND RESULTS:
2,3-Secofernane triterpenoids, alstonic acid A (1) and Alstonic acid 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.
