The separation of twelve common Rauwolfia alkaloids for quantitative thinlayer chromatography can be effected using a minimum of five solvent systems on silica gel layers. The alkaloids can be identified by chromogenic reactions and ultraviolet and infrared spectrometry.
## 17= days and repeatedly examined in ultraviolet light (360 mp). Simultaneously an ordinary silica gel plate and an alumina plate were treated in the same way. On the two latter plates, after a relatively short time (I-Z h), the spots darkened and the fluores-. cence weakened (anthracene and pyre
