Abstract
Dua senyawa santon diprenilasi telah berhasil diisolasi dari ekstrak kulit buah Garcinia mangostana L., yaitu a-mangostin (1) yang berupa padatan kuning, titik leleh 177-178 °C dan y-mangostin (2) yang berupa padatan kuning, titik leleh 193-195 °C. Kedua senyawa telah diisolasi dengan menggunakan metode kromatografi kolom. Pemurnian senyawa a-mangostin (1) dilakukan dengan metode rekristalisasi menggunakan campuran pelarut n-heksana:kloroform p.a. dan senyawa y-mangostin (2) menggunakan kloroform p.a. Penentuan struktur senyawa dilakukan dengan memanfaatkan data spektroskopi (UV, IR, 1H dan 13C NMR).

Two diprenylated xanthose compounds has been isolated from extract of the rind of Garcinia mangostana L., namely α-mangostin (1), as yellow amorphous powder, melting point 177-178 °C, and γ-mangostin (2), as yellow amorphous powder, melting point 193-195 °C. Those two compounds were isolated by using column chromatography methodes. The purification of α-mangostin compound (1) was done by recrystallization using the mixture of n-hexane:chloroform and γ-mangostin compound (2) using chloroform. The structures of these compounds were established based on UV, IR, 1H and 13C NMR.
