Fraction B (5.4 g) was isolated on Sephadex LH-20 with CHCl SB 3 sb -MeOH (3:2) and then purified on a silica gel column with CHCl SB 3 sb -MeOH (30:1) to furnish B 4 b (1.9 mg) and B 9 b (1.2 mg). Compounds B 10 b (7.0 mg) and B 21 b (19.3 mg) were obtained from Fr. D SB 2 sb (7.3 g) on a silica gel column eluting with CHCl SB 3 sb -acetone (10:1), then purified on a Sephadex LH-20 column with MeOH. Compounds B 7 b (9.6 mg) and B 8 b (5.4 mg) were obtained from Fr. D SB 3 sb (3.1 g) by silica gel CC (CHCl SB 3 sb -MeOH, 10:1 to 2:1) and then by Sephadex LH-20 with MeOH. Fraction E (39.3 g) was applied to CC (silica gel, CHCl SB 3 sb -MeOH, 10:1 to 1:1) to provide two major fractions (E SB 1 sb -E SB 2 sb ). [Extracted from the article]
