Abstract
|
|
|
Objectives : A morphological classification among Sophora tonkinensis, Menispermum dauricum and Indigofera kirilowii was made through microscopic observation.
Method : The slice of the tested material made by paraffin section technique was colored with Safranine Malachite Green contrast methods, and then observed and photographed by olymphus-BHT.
Result : 1. The cross-sections of Sophora tonkinensis and Indigofera kirilowii have piths, but Menispermum dauricum does not have any. 2. The lateral parts of Sophora tonkinensis cortex include the square crystal of calcium oxalate, but Indigofera kirilowii does not.
Conclusion : The number of piths and the presence of the square crystal of calcium oxalate can be used to distinguished Sophora tonkinensis from Indigofera kirilowii.
