Of these alkaloids, aristolactams -All (78) and -BII (80), as well as cepharanone-A (82) and doryflavine (83), have been characterized recently, with the structural assignment for doryflavine being only tentative. Noteworthy is the fact that cepharanone-A (82) and aristolactam-BII (80) were found in Stephania cepharantha Y. Hayata (Menispermaceae), and that doryflavine (83) was isolated from Doryphora sassafras Endlicher (Monimiaceae). These are the first recorded occurrence of aristolactams outside the family Aristolochiaceae. 

Menispermaceae is not the only family that contains these bis-type alkaloids. They are also found in Berberidaceae Berberis, Mahonia), Magnoliaceae Michelis, Talauma), Annonaceae Phaeanthus), Monimiaceae Daphnandra, Doryphora), Ranunculaceae Thalictrum (herbaceous)), and others. 

Five new natural bases have been isolated. Doryafranine, C19H21NO3 (CLVI) [mp 92°-94° [a]], +41.5° (CHCI3)], isolated from Doryphora sassafras Endlicher (Monimiaceae) and its structure determined by NMR-spectroscopy and synthesis of the racemic compound (235). Latericine, C23H29NO7 (CLVII) [mp 216°-217° [a]n +40° (Py)], isolated by Preininger e< al. (236) from Papaver lateritium C. Koch, P. pilosum... 

The first example of a naturally occurring isoquinolone was doryanine isolated by Gharbo.et al. (1965) from the Australian sassafras tree Doryphora sassafras, and workers of the same laboratory later isolated doryphomine from the same species (Chen et al. 1974). The authors assumed that isoquinolones may be formed in the plant by oxidation of benzylisoquinolines or similar alkaloids, and this view now appears to be generally accepted (Krane and Shamma 1982). Indirect support for this hypothesis may be the presence of the bisbenzyhsoquinoline alkaloid thali-carpine and its two oxidation products hemandaline and N-methyl-6,7-dimethoxy-l-isoquinolone in Hernandia ovigera (Cava and Bessho 1966).
