Thalidasine

Thalictrum dasycarpum yields this bisbenzy1isoquino1ine alkaloid which is obtained as an amorphous powder. It has [α]²⁷_D- 70° (c 0.89, MeOH) and gives an ultraviolet spectrum with absorption maxima at 275 and 282 IT1J1. The alkaloid yields a crystalline oxalate, m.p. 160-2°C; picrate, m.p. 175-7°C and the methiodide, m.p. 182-3°C. Five methoxyl groups are present and two methylimino groups.

ChEBI: Thalidasine is a member of isoquinolines and a bisbenzylisoquinoline alkaloid.
