A review on phytochemical constituents, analytical data, and pharmacological properties of the genus Plumeria

The genus Plumeria of the Apocynaceae family has a rich history of traditional medicines supported by empirical evidences. This review consolidates diverse biological attributes, phytochemical compositions, physical properties (melting point, shape, optical rotation, etc.), and analytical data (UV, IR, Mass spectroscopic data, elemental analysis) of various species of Plumeria. The review covered the chemistry of wide range of natural compounds like iridoids, triterpenoids, alkaloids, flavonoids, steroids, cardiac glycosides, quinones, anthocyanins, cardenolides, fatty acid esters, lignans, coumarins, etc. found in various species of the genus Plumeria. Analytical techniques including chromatography, IR, UV, and mass spectroscopy have significantly contributed to elucidating the complex chemical profiles of extracts of various species of Plumeria which are systematically presented in a tabular format. The review also defines the historical background, geographical distribution, and traditional uses of various species of the genus Plumeria. The review also includes the mechanisms of action and biotransformation of compounds, providing a deeper understanding of their therapeutic potential. The comprehensive review reveals the significance of the natural products isolated from a number of species of genus Plumeria. It is also suggestive that there is an extensive scope for further investigation to explore new therapeutic components of the genus Plumeria.
