41Chapter 2 Methods of obtaining drugs from medicinal and aromatic plants

Many of the therapeutic agents we use today are plant-based, highlighting the importance of medicinal and aromatic plants in drug discovery and the development of new drugs. The complex nature of plants and the challenges in effectively and efficiently separating and purifying plant-based compounds have historically directed scientists toward synthetic sources for drug development. However, recentments in technology and modern trends in drug discovery that integrate naturaluct development processes indicate that plants will continue to play a significant role in this field in the future. Overcoming the challenges encountered at every stage of drug development from plants requires an integrated interdisciplinary approach that ages both traditional methods and technological advancements. A fast and efficient lection of source plants utilizing ethnopharmacological approaches, high-throughput screening (HTS), and virtual screening methods, coupled with well-designed and tivity-guided extraction and isolation methods, advanced structural characterization techniques, and the transfer of bioactive compounds in preclinical and clinical studies, are essential steps for successful plant-based drug development. New analytical ogies, combinatorial chemistry, computational and screening methods including cial intelligence, molecular modeling, omics technologies for studying interactions tween bioactive molecules and their targets, and the design of biological models represent modern approaches that have demonstrated significant success in obtaining drugs from medicinal and aromatic plants. These methods also hold substantial tial for future research. This section provides an overview of the stages involved in taining drugs from medicinal and aromatic plants and the methods used at each stage. It discusses traditional and modern methodologies in drug development, covering source plant selection, bioactive compound extraction, isolation, characterization, logical assays, clinical trials, new analog development, and optimization processes. nally, the chapter evaluates future expectations for plant-based drug development in light of emerging trends.
