A novel furoquinoline alkaloid, 7-hydroxy-8-(3-methyl 2-butenyl)-4-methoxyfuro[2,3b] quinoline (1) has been isolated from Sarcomelicope glauca leaves. Two new acridone alkaloids, cis-1,2-dihydroxy-1,2-dihydroacronycine (4) and trans-1,2-dihydroxy-1,2-dihydroacronycine (5) have been isolated from the stem bark. Their structures have been elucidated by spectral analysis and chemical correlations. In addition, 12 other alkaloids have been isolated from the leaves and bark of this species. © 1986, American Chemical Society. All rights reserved.
