Plumeria rubra, a tropical flowering plant from the Apocynaceae family, holds notable aesthetic and traditional significance. It is frequently grown in tropical areas as an ornamental shrub or small tree, reaching up to six meters in height. Renowned for its visual appeal, it is especially valued in the creation of leis and other floral arrangements. Although the plant’s sap is toxic, it is recognized for its medicinal and aromatic potential. Additionally, it contains various phytochemicals and demonstrates several biological properties. In this research, the extraction process when further optimized, involved various physicochemical parameters that influenced the yield of flavonoids (quercetin and rutin). These parameters were different solvents and their varying concentration, extraction time, pH, and particle mesh size. The optimal conditions for extracting these flavonoids from this plant leaves were found to be ethanol as the solvent with 100% concentration, 24 hrs extraction time at pH-6, and having a particle size of 72 mesh (210 micron). As a result, the concentration of quercetin and rutin of this plant extract wwere found to be 39.0µg/ml and 30.0µg/ml.
