Abstract :
Traditional medicinal plants such as Swietenia mahagoni and Andrographis paniculata are rich with bioactive compounds. The phenolic composition and antioxidant activity of methanol extract from Swietenia mahagoni and Andrographis paniculata were studied. They were extracted by Soxhlet extraction of 70% methanol solvent. The results obtained from this study showed Andrographis paniculata gave highest percentage yield by 19.94% compared to Swietenia mahagoni at 11.86%. In antioxidant activity, Andrographis paniculata and Swietenia mahagoni showed 89.93% and 60.77% respectively. While for total phenolic content highest in extract of Swietenia mahagoni by 55.0 mg/g and Andrographis paniculata only 7.7 mg/g.
