Medicinal importance of many plants has drawn the attention of researchers to focus on unveiling their therapeutic molecules. Approximately, 25% of the commonly used medicines contain compounds isolated from plants. The World Health Organization has highlighted that many plants in the world have been discovered to possess high medicinal value. The presence of large amounts of polysaccharides, polyphenols, hydrosable tannins and other secondary metabolites makes these plants to be medicinal. Moreover, the plants may contain simple phenolic compounds, phenolic acids, coumarin, flavonoids, stilbenes, hydrosable and condensed tannins, lignin and lignans. The phenolic compounds and flavonoids in particular, are ubiquitous in plants and therefore, represent an important component of a normal human diet. Hence, this review tends to elucidate the extraction of bioactive compounds from Mahkota Dewa (Phaleria macrocarpa) and the extraction methods.
