Pharmacognostic stydy of Cyperus rotundus L
Purpose: To study the morphological and anatomical signs and chemical composition quality of Cyperus rotundus L. for elaboration the identity characteristics its raw material. Methods of analysis: experimental (macroscopic, microscopic analysis, chemical identification). Results: The diagnostic signs have been described for underground organs of Cyperus rotundus L. cultivated in Chinese and Vietnam. Differences have been determined between external and anatomic diagnostic signs and chemical composition of raw materials depending on its cultivation place. Resume: The paper presents the characteristics for identification of fractional and intact underground organs of Cyperus rotundus L.
