Flavonoids, alkaloids, carotenoids, tannins, antioxidants and phenolic compounds are some of the bioactive substances that can be found in plants. Phytochemicals are active constituents. These are not essential nutrients. Chemical entities that are solely responsible for existing pharmacological, microbial or therapeutic activities in the broader sense are generally referred to as active constituents.[1] These phytochemicals provide benefits to human health in addition to those offered by micronutrients and macronutrients. They protect plants from disease and damage and contribute to their color, aroma and flavor. Thus, generally speaking, phytochemicals protect plant cells against various environmental risks such as pollution, stress, drought, UV exposure and attacks by various microorganisms. Their role has recently been discovered in human protection and more than 4,000 phytochemicals have been discovered and classified by protective function, physical characteristics and chemical characteristics and about 150 phytochemicals have been studied in detail. Phytochemicals accumulate in different parts of plants like roots, stems, leaves, flowers, fruits or seeds. They are mainly concentrated in the outer layers of various plant tissues. Phytochemicals are also available in additional forms, but there is very little evidence
