Establishment of quality parameters and pharmacognostical study of Cyperus rotundus Linn. (Cyperaceae): A well-known traditional medicinal plant

Abstract

Objective: Cyperus rotundus (L.) (family-Cyperaceae) occupies a prime role in traditional system of medicine. Since the extensive literature survey did not provide proper and accurate information regarding its study on standardization; therefore, the current study is carried out to establish various quality control parameters of C. rotundus rhizomes. Materials and Methods: The investigation included the determination of various standardization parameters such as macroscopic and microscopic studies, physicochemical parameters as well as phytochemical analysis of crude drug. Results: The microscopy study revealed that rhizome of the plant shows typical monocotyledonous characters with epidermal layer, sclerenchymatous layers, cortex, collateral, closed, vascular bundles, and endodermis. Physicochemical constants such as moisture content, ash values, fluorescence analysis, and extractive values were established. Preliminary phytochemical analysis confirmed the presence of alkaloids, flavonoids, glycosides, saponins, tannins, etc. Conclusion: Various pharmacognostical and physicochemical parameters have pivotal roles in identification, authentication, and establishment of quality parameters of the species.
