Stephania tetrandra Bisbenzylisoquinoline

Beside the use of chromatography in isolation of new alkaloids, several analytical chromatographic determinations of bisbenzylisoquinoline alkaloids have been reported. A TLC method for resolution of components of commercial curare is described an unidentified impurity ( 1%), prisms, mp 275°C (dec.) (MeOH), which interferes with crystallization of d-tubocurarine can be removed in this manner (597). Four TLC systems for evaluation of tubocurarine chloride preparations have been developed (598). TLC-UV methods for analysis of tetrandrine in extracts of Stephania tetrandra are described (599,600). [Pg.197]
