Abstract

Telah dilakukan penelitian tentang penentuan terpenoid iso-arborinol pada akar alang-alang (Impcrata ciliarulrica L). Penelitian ini menggunakan metode deskriptif dengan tiga perlakuan yaitu dengan menggunakan pelarut n-heksana, etil asetat, metanol. Pada uji pendahuluan terpenoid iso-arborinol didapatkan larutan sampel hijaubiru yang membuktikan terdapatnya senyawa terpenoid iso-arborinol pada larutan sampel. Pada uji plat TLC dengan menggunakan pereaksi Lieberman-Burchard dengan terbentuknya bercak noda berwarna ungu yang mempunyai nilai Rf 0,74. Kadar terpenoid iso-arborinol setelah dianalisis dengan spektofotometer UV-visibel didapatkan kadar terbanyak adalah pada pelarut n-heksana yaitu 72,9054 ppm atau 0,0073%, dibandingkan dengan pelarut metanol mengandung 58,0622 ppm atau 0,0058% dan pelarut etil asetat mengandung 38,7604 ppm atau 0,0039%. menunjukkan positif terpenoid iso-arborinol Kata kunci : Akar alang-alang, Terpenoid iso-arborinol
