ABSTRACT

The increasing demand for safe, effective, and sustainable therapeutics has intensified interest in plant-derived bioactive compounds. Phytochemicals exhibit diverse pharmacological properties, including antioxidant, antimicrobial, anti-inflammatory, and anticancer activities, making them valuable candidates for modern drug development. However, challenges related to extraction efficiency, process scalability, quality assurance, and reproducibility limit their industrial translation. This study presents an integrated approach combining phytochemistry, medicinal chemistry, applied biotechnology, microbiology, and chemical process engineering to develop standardized plant-based therapeutics. Advanced extraction techniques, biochemical characterization, microbial screening, and process optimization strategies were employed to enhance yield, bioactivity, and quality consistency. The results demonstrate that techno-chemical integration significantly improves process efficiency, biological efficacy, and regulatory compliance. This research establishes a comprehensive framework for translating traditional phytochemicals into scientifically validated and industrially viable therapeutic products.
