For further purification, the highly active Fr. B (2.8g) was loaded on a silica gel column, eluted with petroleum etherEtOAcgradients,andtheethylacetatecontentofthemixture was increased in a series of 5% steps. The inactive and less activeprovedfractionswerediscarded.Finally,theactiveFr. B2 elutedwithpetroleumether-ethylacetate(85:15)yielded 117mg of compound. The purity of isolated compound was establishedbyHPLCanditsstructurewasconfirmedthrough the interpretation of the spectral data (UV, FT-IR, 1H, 13C NMR, and MS) and further tested for its antioxidant effects.

Untuk pemurnian lebih lanjut, yang sangat aktif Fr. B (2.8g) telah dimuat pada kolom silika gel, dielusi dengan etherEtOAcgradients minyak bumi, andtheethylacetatecontentofthemixture meningkat dalam serangkaian 5% langkah. Tidak aktif dan kurang activeprovedfractionswerediscarded.Finally, theactiveFr. B2 elutedwithpetroleumether-etilasetat (85:15) menghasilkan 117mg senyawa. Kemurnian senyawa terisolasi adalah establishedbyHPLCanditsstructurewasconfirmedthrough interpretasi data spektral (UV, FT-IR, 1H, 13C NMR, dan MS) dan selanjutnya diuji untuk efek antioksidan.
