Object A pharmacognostic study on the root of Euphorbia fischeriana Steud. was carried out for the purpose to provide a scientific basis for the development, utilization and formulation of its quality control standard. Methods Both the macro and micro scopic characteristics of the drug were examined and its chemical constituents monitored by TLC. Results The cross section of the root showed a phloem with an unusual structure of multilayer concentric rings and its TLC showed that the chemical constituents of the aerial and underground parts contained both similar and different ingredients. Conclusion The cross sectional structure and TLC spectrum could provide evidences for the identification of the plant.
