Part of fraction 1 (33.6 g) was subjected to silica gel chromatography by eluting with I n i -hexane-acetone (50:1), enriched with acetone, to furnish four further fractions (1-1-1-4). Fraction 2-3 (12.1 g) was subjected to silica gel chromatography, eluting with CH SB 2 sb Cl SB 2 sb -MeOH (100:1), and enriched gradually with MeOH, to obtain three fractions (2-3-1-2-3-3). Part of fraction 2 (29.7 g) was subjected to silica gel chromatography by eluting with I n i -hexane-acetone (40:1), enriched with acetone to furnish three further fractions (2-1-2-3). Part of fraction 5 (10.2 g) was subjected to silica gel chromatography by eluting with CH SB 2 sb Cl SB 2 sb -MeOH (70:1), enriched with MeOH, to furnish three fractions (5-1-5-3).
