| Sumario: | Extending work on the detection of organic compounds in thin-layer chromatography using the thermal-ultraviolet method, the differential detection of sugars based on a temperature-dependent characteristic pattern revealed under UV and visible light is reported. Specific colours related to structural changes have been observed under UV light. High recoveries of 14C- and also 3H-labelled compounds after thermal-UV detection have been obtained. The detection of lipids and the determination of the sensitivity of the method for these compounds and carbohydrates are described. Results comparable to those in sulphuric acid-based methods have been obtained. In addition, the method has the advantage of a very low background even after prolonged periods of heating at high temperatures. The detection, differentiation and recovery of several methyl glucosides is also reported. © 1983. |
