<p>ABSTRACT<br />Objective: The points of this exploration work were to decide the quantitative examination of bioactive mixes. Customarily, cutting edge meds rely<br />on the phytochemicals got from the plant source in bigger extents. Numerous bioactive auxiliary metabolites have a positive metabolic reaction on<br />different human diseases.<br />Methods: In the present examination, Artemisia nilagirica, leaves were gathered, dried, powdered and put away in hermetically sealed compartments<br />for quantitative investigation of phytochemicals according to standard strategies.<br />Results: The methanolic leaf concentrate of enrolled 4.33 mg of alkaloids, 1.22 mg of saponins, 12.4 mg of tannins, 24.3 mg of glycosides, 10.2 mg<br />terpenoids, 1.33 mg of coumarin, 59.4 mg of amino acids, 12.2 mg of fatty acids, 17.2 mg of flavonoids, 10.2 mg of phenols, and steroids in follows<br />separately.<br />Conclusion: The plant has a high helpful quality as far as an assortment of phytochemicals from leaf remove and had let to a sure level toward<br />extraction and refinement of specific bioactive mixes for human nourishment.<br />Keywords: Artemisia nilagirica, Secondary metabolites, Quantitative analysis, Leaf extract, Flavonoids.</p>

From very simple molecular building blocks, life has created an astonishing diversity of molecules, some of which are extremely complex structures that prove very difficult to synthesize in a laboratory. ‘The chemistry of life’ describes how proteins, which serve a myriad of purposes, and nucleic acids, another form of biopolymer, are constructed from molecular building blocks called amino acids and nucleotides respectively. It goes on to explain the polymerization processes involved in the biosynthesis of many other natural products; the functions of proteins, DNA, and RNA; and the different theories proposed to explain chemical evolution, or prebiotic chemistry. Enzymes and nucleic acids are increasingly being used in commercial applications.
