PHARMACOGNOSTIC AND PRELIMINARY PHYTOCHEMICAL EVALUATION OF NELAMUCHCHALA (GYMNOSTACHYUM FEBRIFUGUM BENTH.)
Folklore medicine is an integral part of Ayurveda. Nelamuchchala (Gymnostachyum febrifugum Benth) is one such drug which is traditionally used for fever, ulcers, Cough and metrorrhagia. Aim: The present study deals with Pharmacognostic, determination of Taste and preliminary Phytochemical investigations of root. Materials and Methods: The study includes microscopy, Physical analysis, determination of taste and preliminary phytochemical evaluation using methods given in Indian Ayurvedic Pharmacopoeia and Pharmacognosy by Dr. Khandelwal K.R. Results and Discussion: The microscopic structure of root shows as Polyarch vascular bundles, central large thick walled parenchymal pith and presence of calcium oxalate crystals in parenchymal cell of cortex. The preliminary phytochemical analysis revealed the presence of carbohydrates, flavanoids, phenol and steroids in various solvent extracts. The pH of the drug was 6.50. The ash analysis revealed the presence of fluoride, sulphate, chromate and aluminium. Tikta and Kashaya rasa determined by taste with tongue followed by ‘blind method’. Thin Layer Chromatography (TLC) was carried out after organising the appropriate solvent system, in which three spots of phenols were distinguished. The Rf value are 0.1702, 0.2638 and 0.5361. Conclusion: The result of the present study can be useful for the identification and preparation of a monograph of the plant. Observations could be considered to be the reference standards in future studies.
