Alkaloids differ in their physiological effects: some of them weaken or stimulate the nervous system, others paralyze nerve endings, dilate or narrow blood vessels, and others are considered to have an analgesic effect. It is studied using methods such as chromatography, spectroscopy, and continues to get high results in these methods. The advantage of this method is that in the study of alkaloids, the additives contained in alkaloids are considered extremely necessary for the study of organic and meningeal substances, as well as for the analysis of biological objects. The chromatography method is widely used in the study of detection, isolation of compounds contained in alkaloids. On the other hand, the spectroscopy method is studied by exposing light to alkaloids. The chemical composition of alkaloids is studied by ultraviolet light and some reagents.

Tea is a unique concentrate of the most valuable taste, dietary and medicinal substances. Not a single drink has such a rich complex of biologically valuable, healing qualities. The therapeutic and prophylactic effect of tea makes it one of the important means of modern medicine. Along with alkaloids (caffeine, theobromine and theophylline), which give the drink a stimulating effect, tea leaves contain biologically valuable substances: tannin, various vitamins, trace elements, essential oils, soluble nitrogenous compounds and all essential amino acids. It contains many different phenolic compounds that give the drink unique healing properties and the current level of knowledge about the composition of tea helps to find objective criteria for determining its quality and move from the categories of subjective organoleptic and aesthetic assessments to a short and dispassionate language of numbers.
