The Extraction of Bioactive Agents from Calophyllum inophyllum L., and Their Pharmacological Properties

Calophyllum inophyllum L. has been used for many generations by Pacific Islanders because of its numerous health and aesthetic advantages. The leaves, stems, roots, fruits, flowers, and seeds of this plant contain significant phytochemicals, including flavonoids, coumarins, fatty acids, and xanthones, which have been shown to have wound healing, analgesic, anti-inflammatory, antiaging, anti-arthritic, anti-cancer, anti-proliferative, anti-diabetic, anti-microbial, and anti-HIV effects. The chemical profiles and bioactive potential may vary due to different extraction techniques, plant parts, and geographical origins. Extraction is the essential first step in the analysis of bioactive compounds that leads to further separation, identification, and characterization. Conventional methods like maceration, Soxhlet, and percolation are often used to extract bioactive compounds from C. inophyllum. However, little study has been carried out on non-conventional methods such as pressured liquid extraction, supercritical fluid extraction (SFE), and ultrasound-assisted extraction. The SFE method can be used to extract bioactive compounds from C. inophyllum to retain their pharmacological properties for application in pharmaceutical and cosmetic products.
