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)aporphin10-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[deg]quinolin-2-ol; 2).
