One fascinating discipline in Biotechnological studies is the examination of phytochemicals as possible agents for developing medications and enhancing nutritional characteristics. The phytochemicals have impacts for many areas, like pharmaceutical development, food quality control, and studying plants. The newly suggested paper-based colorimetric method was used coupled with traditional procedures to perform chemical tests for flavonoids, tannins, Saponins, carbohydrates, Phenols and alkaloids, Anthraquinones, Steroids, glycosides. Results were reminiscent of conventional methods, revealing the paper strips' effectiveness in identifying the tannins, Carbohydrates, flavonoids, saponins, phenols and alkaloids present in the evaluated samples. In this study Limnophila aromatic were used as a medicinal herb, water and concentrations L. aromatic have harvested via a fluid consisting of 100% ethanol, methanol, plus solvent into H2O. assessing the fluid extract of C's oxidative as well as radical elimination properties. These outcomes highlight the possibility of utilizing paper-based colorimetric strips as rapid and reliable methods for phytochemical detection, with benefits in terms of affordability, simple use, and accessibility. Further, it can detect many sample simultaneously. Additionally, the key objective of this study's is to gather and compile data on medicinal herbs, categorize them according to analyses of their plant chemicals concealer, and give the research society knowledge to support future scientific studies on medicinal plants. Additionally, they may be added to medications, dietary supplements, or other products as nutrients. They may also offer insights into the consequences of a revolution to further study, manufacture, and application of phytonutrients as supplements.
