- Abstract
Fraction H2 (1.2 g) was separated using column chromatography (CC) eluting with I n i -hexane-CH SB 2 sb Cl SB 2 sb (90:10) to furnish B 1 b (7 mg). By using silica gel CC, the eluted gradient CH SB 2 sb Cl SB 2 sb -MeOH, Fr. B4 (154 mg) afforded two compounds B 9 b and B 10 b of 3 mg each. Compounds B 4 b (3 mg) and B 7 b (4 mg) were successively obtained after purification of Fr. H4 on silica gel CC ( I n i -hexane-EtOAc, 85:15). The I n i -hexane extract (12.8 g) was subjected to silica gel column chromatography (gradient of I n i -hexane-EtOAc, 100:0-0:100) to afford fractions H1-H7.
