Fractions containing a mixture of compounds were rechromatographed over polyamide columns. The chromatography column was eluted by CHCl SB 3 sb and CHCl SB 3 sb -EtOH in various proportions. The extracts were evaporated to afford CHCl SB 3 sb (42.0 g), EtOAc (64.0 g), and I n i -BuOH extracts (228.0 g).
