- Abstract
Subfraction 1-4 (2.7 g) was further purified on a silica gel column using I n i -hexane-CH SB 2 sb Cl SB 2 sb mixtures to obtain oxyberberine ( B 5 b ) (3 mg). Part of Fr. 1 (12.5 g) was subjected to silica gel chromatography, eluted with I n i -hexane-CH SB 2 sb Cl SB 2 sb (1:1), and enriched gradually with CH SB 2 sb Cl SB 2 sb , to furnish five subfractions (1-1-1-5). Subfraction 2-4 (2.2 g) was further purified on a silica gel column using CH SB 2 sb Cl SB 2 sb -MeOH mixtures to obtain berberine ( B 6 b ) (54.8 mg). Subfraction 3-1 (2.1 g) was further purified on a silica gel column using CH SB 2 sb Cl SB 2 sb -MeOH mixtures to obtain 3,4-dimethoxybenzoic acid (4 mg) and syringic acid (16 mg).
