The awareness of natural healthy lifestyle is growing these days. The spices and herbs as natural medicine have been widely used. Teak (Tectona grandis) is one of native herbs from Indonesia. The Teak timbers have been valued and majored for decades, whereas, its leaves have been used as traditional food packaging and medicine. Many researches purposed on its development have been conducted. In this research, novel method of extraction names Microwave-Assisted Extraction (MAE) was applicated to gain antioxidant compound of Teak leaves effectively. This work highlighted a comparative qualitative phytochemical screening on Teak leaves. Antioxidant activities of each extract were brought by Total Phenolic Content Folin-Ciocalteau method; DPPH (2-2-diphenyl-1-picrylhydrazyl) radical scavenging assay; Ferric-Reducing Antioxidant Power assay; and H2O2 (hydrogen peroxide) radical scavenging assay. MAE possessed higher antioxidant activity than Soxhletation. The aim of this study is comparing novel and conventional extraction method of Teak leaves antioxidant related to its effectivity and efficiency towards antioxidant activity.
