Pharmacognostic study of Rosa damascena petals

Objective: The purpose of the present study was to explore the Pharmacognostic parameters for standardization of Rosa Damascena Rosa Damascena Petals.The flowers of were authenticated and shade dried.Material and Methods: Petals were separated and powder characteristics, behavior and fluorescence analysis, physiochemical assessment, and micrometric investigation were carried out.Dried Petals powder was then extracted with aqueous, Rosa Damascena alcoholic, chloroform, petroleum ether, and ethyl acetate solvents and their extractive values were calculated.The phytochemical screening of petals was carried on all the different extracts.The Rosa DamascenaResults: characteristic macroscopic and microscopic features of petals include the presence of wavy epidermal cells, spirally thickened xylem vessels, lignified fibers, oil globules, prismatic, acicular clusters and conglomerate of crystals calcium oxalate and Cystoliths crystals of calcium carbonate.Powder showed characteristic fluorescent property when treated with different reagents.Physicochemical exploration showed values for moisture content, moisture sorption capacity, ash values and extractive values which are within the limits of World Health Organisation standards for the crude drug from medicinal plants.Micromeritic analysis of petal powder reveals good flowability.Aqueous and ethanolic extractive values were found to be higher when compared to that of extractive values of chloroform, petroleum ether, and ethyl acetate.Preliminary Phytochemical exploration indicated the presence of carbohydrates, glycosides, alkaloids, flavonoids, amino acids, and triterpenoids. Conclusions: supplement the information regarding pharmacognostical characteristics, physiochemical evaluation, micrometric analysis and phytochemical exploration in Ayurvedic system of medicine for its identification.
