Chemical Constituents of Salvia cavaleriei var. simplicifolia.

Fraction 9 (3.4 g) was purified with Sephadex LH-20 (CH SB 2 sb Cl SB 2 sb -MeOH, 1:1) and silica gel column chromatography (CH SB 2 sb Cl SB 2 sb -EtOAc, 11:1-0:1) to afford compounds B 6 b (20 mg) [[14]] and B 7 b (30 mg) [[15]]. The CH SB 2 sb Cl SB 2 sb fraction was subjected to silica gel column chromatography (CH SB 2 sb Cl SB 2 sb -MeOH, 90:1-0:1) to afford twelve fractions. The PE fraction was subjected to silica gel column chromatography (PE-EtOAc, 20:1-0:1) to afford twelve fractions. Fraction 9 (10 g) was subjected to Sephadex LH-20 (CH SB 2 sb Cl SB 2 sb -MeOH, 1:1) and silica gel column chromatography (CH SB 2 sb Cl SB 2 sb -MeOH, 40:1-1:1) to afford compounds B 3 b (44 mg) [[11]], B 4 b (16 mg) [[12]], and B 5 b (4 mg) [[13]].
