Abstract:ObjectiveTo conduct pharmacognosical studies on the roots and leaves of Allamanda cathartica L. and Lantana camara L. for the purpose of offering references to their clinical use, rescuing poisoned persons , development and usage. MethodsThe plants' characters and their microscopic structures, as well as their physicochemical properties were studied. ResultsPhellem in horizontal sections of Allamanda cathartica L. was thick, clearly consisting of two layers; and many starch grains and crystal clusters of calcium oxalate were found in the cross sections of its stems and its powder. Structures of cells of rays in the horizontal sections of Lantana camara L. were relatively exceptional; sclerenchymae was discovered in the square cross sections of its stems; its powder possessed unicellular non-glandular hairs, in which secretory cells containing orange oil drops were found. ConclusionThe result can be taken as the basis for the identification of the two plants.
