Publications serve as the concrete art form for the scientist. It is his modus operandi. Authorship is akin to success and achievement. It cannot and should not deteriorate into a bargaining tool or commodity. Dardik
Shikanga, E.A., Viljoen, A.M., Combrinck, S., Marston, A. 2011. Isolation of Sceletium alkaloids by high-speed countercurrent chromatography. Phytochemistry Letters 4: 190–193.

The alkaloids of Sceletium tortuosum (Mesembryanthemaceae) exhibit important pharmacological properties and are used for the treatment of psychiatric and psychological conditions, including depression, anxiety, drug dependence, bulimia and obsessive-compulsive disorder. The all-liquid technique of high-speed countercurrent chromatography provides an excellent tool for the rapid isolation of these alkaloids in high yields.
