Physico-chemical Evaluation, Preliminary Phytochemical Investigation, Fluorescence and Tlc Analysis of Leaves of the Plant Lasia Spinosa (lour) Thwaites

Objective: To investigate the physico-chemical parameter, preliminary phytochemical screening, fluorescence and Thin Layer Chromatographic analysis of the leaves of the plant Lasia spinosa (Lour) Thwaites. Methods: The fresh and powder leaves of the plant Lasia spinosa (Lour) Thwaites (Araceae) were studied by morphology, preliminary phytochemical screening, and florescence analysis of powdered drug. Other physicochemical parameters were also performed as per WHO guide lines. Results: The dried powder leaves were investigated by morphology. The results of physic-chemical parameters such as loss on drying and ash values, extractive values, preliminary phyto-chemical screening, percentage of extractive values fluorescence analysis and TLC are in the table no of 1, 2, 3, 4, 5 and 6 respectively. Conclusion: The present information on the pharmacognostic evaluation of the plant drug L. spinosa delivered the qualitative and quantitative parameters serve the important information to the identity and to determine the quality and purity of the plant material in the future. It also signify the important information of the closely related other species and varieties.
