Abstract:

Juglans regia Linn belongs to family Juglandaceae. It is commonly known as Walnut tree. Juglans regia bark has been claimed to possess anti-inflammatory, blood purifying, anticancer, depurative, diuretic and laxative activities. The bark is finely powdered and used to prevent bleeding gums and as a mouth rinse. The present investigation deals with microscopic evaluation of bark and establishment of its quality parameters, including physicochemical, phytochemical evaluation, HPTLC analysis & Microbial load. Chief microscopic characters include cork, phloem fibres with stone cells & calcium oxalate crystals. Phytochemical screening revealed presence of reducing sugars; alkaloids; tannins & phenols; steroids & saponins. The bark powder was found to be free from pathogenic organisms. The study will provide referential information for the correct identification of the crude drugs.

Key words: Juglans regia Linn, Pharmacognostic study, Phytochemical analysis, HPTLC analysis.
