Abstract

Medicinal plants make many chemical compounds for biological function. The medicinally active compounds are called secondary metabolites. Extraction is used for separating medicinal active portions of plants using selective solvents through standard procedure. Phytochemical screening refers to the extraction, screening and identification of the medicinal active substances found in plants. These bioactive principles subsequently may lead to drug discovery and drug development. They are mainly used as traditional medicine in human diseases. Aim and Objective: It was to optimize the extraction method and preliminary phytochemical screening for phytoconstituents exist in the selected plant. Method: The extraction was carried out using cold maceration process. The experimental procedures were performed for identification of primary and secondary metabolites present in hydroalcoholic extract of Peristylus goodyeroides. Results and Discussion: The % yield of extract was found as 15.4%w/w. From the phytochemical tests, the results were obtained for the presence of active secondary metabolites like steroids, triterpenoids, alkaloids, glycosides and flavanoids. Conclusion: The detected class of active constituents will play major place in herbal drug development after characterization and pharmacological activity studies. Even rare species of plants also contain important active principles. From this, the care must be taken to protect exploitation of the species from the particular regions.
