In this paper, we investigate the potency of Leea indica locally known as Memali plant from Tasik Chini, Pahang as a potent antioxidant and antimicrobial agent. Antibacterial activity of root, stem and leaf extracts of L. indica was evaluated against skin disease caused-microb Staphylococcus aureus and Staphylococcus epidermidis. Antioxidant activity was assessed by 2,2 diphenyl-1-picrylhydrazyl ( DPPH) thin layer chromatography (TLC) and dot blot assay method. The dichloromethane (DCM) extracts of all three parts displayed obvious antibacterial effect compared to other extracts and DCM extracts from leaves was the most effective in inhibiting the growth of S. epidermis with inhibition zone (IZ) of 18 mm. The methanol extracts from stem scavenged DPPH radicals more effective than root and leaf extracts at a concentration as low as 0.19 mg/ml. The antibacterial and antioxidant properties of leaves and stem might be attributed to the high content of terpenoid and phenolic. Thus, Memali appears to be a promising source of bioactive ingredients with antioxidant and antimicrobial activity. Keywords: Leea indica, antimicrobial, antioxidant, phytochemicals, secondary metabolitesAbstrak Kertas kerja ini meliputi penyelidikan ke atas potensi pokok Leea indica dari Tasik Chini, Pahang yang juga dipanggil Memali sebagai agen antioksidan dan antimikrob. Bahagian akar, batang dan daun dipilih untuk kajian aktiviti antibakteria dan antioksidan di mana ujian antibakteria menggunakan bakteria penyakit kulit seperti Staphylococcus aureus and Staphylococcus epidermidis. Ujian antioksidan menggunakan kaedah kromatografi lapisan nipis 2,2 diphenyl-1-picrylhydrazyl (DPPH) dan ujian dot blot. Didapati ekstrak dari diklorometana (DCM) menunjukkan aktiviti antimikrob yang lebih tinggi berbanding dengan ekstrak lain dan ekstrak dari daun mempunyai aktiviti yang paling tinggi dengan zon perencatan 18 mm. Ujian antioksidan menunujukkan ekstrak metanol bahagian batang lebih efektif memerangkap radikal DPPH pada kepekatan serendah 0.19 mg/ml. Sifat antioksidan dan antimikrob ini berkemungkinan akibat daripada adanya kandungan bahan seperti terpen dan fenolik yang tinggi. Maka pokok Memali dilihat sebagai punca asas bahan bioaktif yang bersifat antimikrob dan antioksidan.
