A review on: modern methods of extraction in the estimation of terpenoids and resins
Abstract
Terpenoids are the most abundant compounds among natural products and represent an important group of secondary metabolites in plants with diverse structural forms. They play physiological processes. They are secreted by plants as a protective response to injury or pathogen attack and serve as physical and chemical barriers. The fact that trees producing copious amounts of resin occur predominantly in tropical and subtropical environments may be related to growing evidence that these substances play a role in protecting plants against herbivores and microorganisms. Accurate extraction and quantification of terpenoids and resins are essential for quality control, pharmacological research, and commercial standardization. The complexity of plant matrices and the sensitivity of bioactive compounds necessitate efficient and selective extraction techniques
