Medicinal plants have served as a primary source of therapeutic agents throughout human history and continue to contribute significantly to modern pharmacotherapy. In recent decades, the renewed interest in plant-based medicines has been driven by increasing concerns over the adverse effects of synthetic drugs, rising healthcare costs, and a global shift toward natural and sustainable therapeutic options. However, the transition from traditional knowledge to evidence-based medicine requires systematic validation through scientifically robust methodologies. In vitro screening techniques have emerged as essential tools in this process, enabling the rapid and controlled evaluation of biological activities associated with plant-derived compounds. These methods facilitate the identification of pharmacologically active constituents, elucidation of mechanisms of action, and preliminary assessment of safety profiles. This review provides a comprehensive and critical overview of in vitro approaches used in medicinal plant research, including phytochemical analysis, antioxidant assays, cytotoxic and anticancer evaluations, antimicrobial testing, and advanced cell-based models. Particular emphasis is placed on the importance of sample preparation, authentication, extraction, and standardization, as these factors significantly influence reproducibility and experimental reliability. Furthermore, the applications of in vitro screening in drug discovery, validation of ethnomedicinal claims, toxicity assessment, and nutraceutical development are discussed in detail. Despite inherent limitations in mimicking complex in vivo systems, in vitro methodologies remain indispensable due to their efficiency, cost-effectiveness, and adaptability to high-throughput platforms. Overall, this review highlights the pivotal role of in vitro screening as a scientific bridge connecting traditional medicinal knowledge with modern pharmaceutical research, thereby facilitating the rational development of plant-based therapeutics.

Today Pharmacognosy functions as an essential scientific basis for discovering anticancer medications through research of natural medicating plants alongside additional natural resources. The article evaluates the vital role which pharmacognosy plays when developing compounds that act as cancer treatments. The article describes extraction techniques alongside screening and characterization protocols that help researchers find anticancer compounds among bioactive plant principles. The discovery of pharmacological agents’ taxol and camptothecin and vinca alkaloids stands as one of the primary outcomes alongside their subsequent development into medicinal drugs. The scope includes modern screening procedures linked with molecular docking approaches along with biotechnological growth that enhances both efficiency and pharmaceutical research outcomes in pharmacognosy. The review addresses difficulties alongside existing trends and future guidance about employing natural products for developing oncological drugs.
