A short review on effective extraction procedures for herbal drugs

Pharmaceutical extraction involves separating medicinally active components from plant or animal tissues using selective solvents and standardized procedures. The resulting products are typically impure liquids, semisolids, or powders intended for oral or external use. Traditional medicine, relying heavily on medicinal plants, is predominant in many developing countries, with 80% of the global population depending on herbal remedies. The extraction process of herbal drugs focuses on isolating bioactive compounds from various plant parts using different techniques and solvents to create concentrated therapeutic extracts for medicinal use. Key steps include plant selection and processing, extraction methods, solvent selection, optimization of conditions, post-extraction processing, and quality control. Herbal medicines are often used as alternatives to conventional treatments due to their efficacy and reduced side effects. The secondary metabolites, such as alkaloids, saponins, terpenoids, flavonoids, phenolic compounds, and tannins, contribute significantly to their biological and pharmacological properties.
