Telah dilakukan isolasi dan uji BSLT ekstrak etil asetat daun meranti sabut (Shorea ovalis [Kort.]). Isolasi menggunakan metode kromatografi kolom dengan cara Step Gradient Polarity (SGP). Penelitian ini bertujuan mengisolasi senyawa metabolit skunder dan uji BSLT ekstraks etil asetat daun meranti sabut (Shorea ovalis [Kort.]). Dari hasil penelitian didapatkan senyawa murni IA dan dikarakterisasi dengan spektrum IR, H-NMR, C-NMR, HSQC dan HMBC serta reaksi warna menggunakan pereaksi Liebermann-burchard. Hasil karakterisasi senyawa IA disimpulkan adalah senyawa golongan fitosterol dengan perkiraan rumus molekul C27H48O. Hasil uji BSLT ekstrak etil asetat daun meranti sabut pada konsentrai 100, 10 dan 1 ppm diperoleh nilai LC50= 40.45 ppm dengan persen kematian larva Artemia salina sebesar 56,6 %, tergolong sangat toksik.
