Undergraduate thesis, Institut Teknologi Sepuluh Nopember. Garcinia tetrandra Pierre wadung merupakan salah satu famili Clusiaceae yang berpotensi sebagai sumber penghasil senyawa-senyawa santon.

Metode ekstraksi menggunakan pelarut metilen klorida dan fraksinasi dilakukan dengan kromatografi cair vakum, kromatografi kolom gravitasi dan kromatografi sistem radial atau kromatotron serta kromatografi kolom sephadex. Pemurnian dilakukan menggunakan metode kristalisasi dan rekristalisasi. Pembuktian senyawa murni dilakukan dengan tiga sistem kepolaran masing-masing dengan noda tunggal.

The method of extraction was conducted using dichloromethane as solvent and was fractionated using vacuum liquid chromatography, gravity column chromatography, chromathotron and sephadex column chromatography. The purification of compounds were done using crystalitation and recrystalitation methods. Proof of pure compounds were carried out by three systems of polarity with a single stain.
