A New Strychnobrasiline Base of Strychnos Mattogrossensis

A new strychnobrasiline derivative, 12-hydroxy-10,11-dimethoxystrychnobrasiline 1 , has been isolated from the stem barks of Strychnos mattogrossensis . Its structure was established by spectroscopy analysis (1D and 2D NMR, MS, IR, UV) and literature data comparison. Two other known indoline alkaloi...

Summary:A new strychnobrasiline derivative, 12-hydroxy-10,11-dimethoxystrychnobrasiline 1 , has been isolated from the stem barks of Strychnos mattogrossensis . Its structure was established by spectroscopy analysis (1D and 2D NMR, MS, IR, UV) and literature data comparison. Two other known indoline alkaloids were also obtained from the heartwood, 12-hydroxy-11-methoxystrychnobrasiline 2 and strychnobrasiline 3 .
