A review on: estimation and utilization of phytoconstituents in digoxin, atropine, vinblastine

The word Pharmacognosy comes from the Greek language. Pharmakon means drug, and gignosco means to acquire knowledge. Medicinal plants are rich in bioactive phytoconstituents that play an important role in therapy.Digitoxin, atropine, and vinblastine are classical examples of plant-derived drugs with high clinical value. Estimated by spectrophotometry, HPLC, and immunoassays for therapeutic drug monitoring. Crude drugs are natural substances obtained from plants, animals, minerals, marine life, or microorganisms. Pharmacognosy is the scientific study of drugs that come from natural sources such as plants, animals, and microorganisms. Primary metabolites, such as sugars, amino acids, and lipids, are essential for plant growth and development. Secondary metabolites, on the other hand, are not directly involved in growth but play a vital role in the survival of plants.
