Introduction: Standardization of drugs is a crucial step in both experimental and clinical trials. It helps to ensure that the drug is consistent in terms of its composition, quality, and potency, which is essential for ensuring its safety and efficacy in treating the intended condition. In the case of Ayurvedic medicine, the texts describe a detailed process for examining and standardizing drugs, which involves identifying the source, selecting the appropriate plant part, processing and preparing the drug, and testing its efficacy through various methods. Regarding Cocos nucifera Linn shell, it is true that this plant part is used in various culinary and medicinal applications1. The shell of the coconut fruit has been reported to possess various pharmacological properties, including antimicrobial2 and helps in curing eczema3. Objective: To determine the Preliminary Pharmacognostical and phytochemical analysis of Cocos nucifera Linn shell. Materials and method: Collection of Cocos nucifera Linn shell was done from natural habitat of Udupi district and analytical studies were carried out according to the standard protocols. Result and Discussion: Microscopic characteristics of coconut shell revealed to have vessels and sclerids, tracheids, isolated phloem fibres, parenchymatous ground tissue, vessels which are pitted, vessels which are broadly pitted, bundle of sclerenchymatous fibres and starch grains. Loss on drying showed 6.48%, Total ash weight is 2.43%, acid insoluble ash is 0.29%, water soluble ash constituted to about1.58%, Water soluble portion of shell is 7.31%, Alcohol soluble extractive is 5.81% along with physicochemical parameters and HPTLC for coconut shell kashaya of was tested. Conclusion: The analytical study performed and recorded will be helpful for further researches in clinical practice.
