Chemical profiling and isolation process of compounds 6 and 7. All samples were analyzed at 220 nm on Prevail reversed phase C18 column with a gradient of H2O (A)/acetonitrile (B) (10 min 100% of A, 30 min from 0% of B to 100% of B, 10 min 100% of B). Supernatant extract (SE) was fractionated using flash chromatography with a reversed phase to afford 14 fractions. Compounds 6 and 7 were isolated from the fifth fraction using semi-preparative HPLC on Prevail C18 column. RE: resin extract.
