Abstrak
Telah berhasil diisolasi senyawa golongan fenilpropanoid dengan nama "skopoletin” dari kulit umbi ubi jalar (Ipomoea batatas L.). Ekstraksi senyawa dilakukan dengan metode maserasi menggunakan pelarut metanol, dilanjutkan dengan partisi menggunakan n-heksana dan etil asetat. Pemisahan dan pemurnian senyawa dilakukan menggunakan teknik kromatografi kolom gravitasi. Struktur senyawa dianalisis berdasarkan data spektroskopi UV/Vis, 1D, dan 2D-NMR.
