Medicinal plants provide a wealth of information about and experience with treating a wide range of illnesses, thanks to their biologically active components and medicinal characteristics. The physiologically active molecules found in plants and plant products, such as vitamins, fibre, antioxidants, and chemicals that decrease cholesterol, constitute an integral aspect of a healthy human diet. There is a lot of data on this issue, but the nutritional value of plants is still not established. In the past, many nutrients found in plants and substances that improve health were found to have worth via trial and error. By the beginning of century, many plant metabolites could be quantitatively and qualitatively measured thanks to the use of nuclear magnetic resonance, infrared spectroscopy, and chromatography. Plants have long been employed by Ayurvedic practitioners to treat a wide range of diseases. Consequently, following Ayurvedic assertions on plants, scientists are now concentrating on studying and describing different plants and plant components for their potential to treat various ailments. The challenges of element separation, identification, and quantification in complex plant extracts are not going away any time soon. The good news is that there is a vast array of detectors, specialist stationary phases, and separation methods available today that can help you overcome any separation difficulty with the right combination of speed, sensitivity, and selectivity. Numerous analytical methods have been established for the purpose of identifying and quantifying phytochemicals; these methods include chromatography, hyphenated techniques, capillary zone electrophoresis, and spectrophotometric approaches.
