Three new indole N-oxide alkaloids, fargesine (5-hydroxy-12-methyl-10,11,12,13-tetrahydro-1 H-azepino[5,4,3-cd]indole N(12)-oxide, 1), plectocomine 12-methyl-5- O-beta-D-glucopyranoside N(12)-oxide (2), and bufotenine 5-O-beta-D-glucopyranoside N(12)-oxide (3), were isolated from the root and stem of Evodia fargesii Dode along with five known compounds. The structures of the new alkaloids were elucidated on the basis of spectroscopic analysis.

Two new arylnaphthalene lignan glycosides, named reticulatusides A (1) and B (2), together with eight known compounds were isolated from the 95% EtOH extract of the whole plant of Phyllanthus reticulatus. The structures of the new compounds were elucidated by spectroscopic methods.
