Two New Aporphine Alkaloids from Litsea glutinosa

HELVETICA CHIMICA ACTA, Issue 9 2005
Jing-Hua Yang
Chemical examination of the BuOH extract of the leaves and twigs of Litsea glutinosa collected from Xishuangbanna resulted in the isolation of two new aporphine alkaloids, namely litseglutine,A (1) and B (2), along with two known aporphine alkaloids, boldine (3) and laurolitsine (4). The structures of the new alkaloids have been elucidated on the basis of spectra analysis as 6-demethyl-9-methoxy-1,2-(methylenedioxy)aporphin-10-ol (=6,7,7a,8-tetrahydro-10-methoxy-5H -benzo[g]-1,3-benzodioxolo[6,5,4- de]quinolin-11-ol; 1) and 1,10,11-trimethoxyaporphin-2-ol (=5,6,6a,7-tetrahydro-1,10,11-trimethoxy-6-methyl-4H -dibenzo[de,g]quinolin-2-ol; 2).
