Background: Alectryon serratus was selected from a screening program devoted to search naturally occurring antimalarial compound from plants in Alas Purwo National Park, Banyuwangi, East Java, Indonesia. The previous studies showed that ethanol extract of A. serratus leaves contains some polyphenol compounds. Objective: This study was designed to isolate and investigate antiplasmodial activity of polyphenol compounds. Material and Methods: The ethanol extract of A. serratus leaves was fractioned using liquid{\textendash}liquid fractionation and column chromatography. Isolated compounds were identified using High-performance liquid chromatography, ultraviolet-visible, nuclear magnetic resonance, and compared with references. The isolates were tested in vitro for antiplasmodial activity against chloroquine-sensitive 3D7 strain of Plasmodium falciparum. Thin blood smears were used to assess the levels of parasitemia and growth inhibition of the isolates. Result: Half maximal Inhibitory concentration of Gallic acid (1), methyl gallate (2), and kempferol-3-O-rhamnoside (3) were 0.0722 μM, 0.0128 μM, and 3.4595 μM, respectively. Conclusion: The results suggest that gallic acid, methyl gallate, and kempferol-3-O-rhamnoside isolated from A. serratus leaves have antiplasmodial activity and are potential to be developed as antimalarial drugs.
