Abstract: Nyctanthes arbor-tristis is commonly known as Night Jasmine, Harshinghar and Parijat is an important traditional medicinal plant. Present study deals with preliminary phytochemical screening and quantification estimation of bioactive constituents like phenolics, flavonoids, alkaloids, glycosides, cardiac glycosides, tannins, terpenoids and proteins using standard methods. These are the constituents which produces definite physiological actions on human body. Medicinal value of the plant lies in presence of these chemical substances commonly known as secondary metabolites. Synthesis of these active ingredients is organ/stage specific depending on physiological condition of the plant, different environmental parameters such as temperature and rainfall. Crude ethanolic extracts from leaf, stem, flower and fruits of Nyctanthes arbor-tristis plant were prepared using Soxhlet method. Presence of major phytochemicals like Phenolics, Flavonoids and Alkaloids had been detected in all the extracts whereas quinones, anthraquinones and carboxylic acids were found to be absent in all plant parts extracts. Quantitative analysis showed that Flower and Stem extracts possess higher phenolics (40.63 and 28.02 mg of GAE/g DW), Flavonoids (362.62 and 120.43 mg of QE/g DW) and Alkaloids (87.08 and 41.29 mg of AE/g DW) compared to Leaf and Fruit extracts. From this data, it can be concluded that both Flower and Stem extracts could be a good source of important bioactive constituents possessing valuable therapeutic compounds.
