[Plants from New Caledonia. Alkaloids from Sarcomelicope dogniensis Hartley stem bark]

Two new pyranofuroquinoline alkaloids, cis-1,2-dihydroxy-1,2 dihydroacronydine 2 and trans-1,2-dihydroxy-1,2-dihydroacronydine 3 have been isolated from Sarcomelicope dogniensis stem bark. Their structures have been elucidated by spectral analysis and chemical correlations. In addition, 11 other alkaloids have been isolated from the stem bark of this species.
