To study the chemical constituents from roots of Platycodon grandiflorum.
Column chromatography (silica gel, macroporous resin, sephadex LH - 20 and the preparative RP - HPLC were used to isolate the constituents. Their structures were elucidated by physical and spectral data.
Eight compounds were isolated and identified as tangeritin (1), 3-O-beta-D-glucopyranosylplatycodigenin methyl ester (2), 3-O-beta-D-glucopyranosylplaticogenic acid A lactone (3), 3-O-beta-D-glucopyranosylplatycodigenin (4), deapio-platyconic acid A lactone (5), deapio-platycodin-D (6), platycoside-G1 (7) and platycoside-E (8).
Compounds 1,3 and 5 were isolated from this plant for the first time.
研究桔梗根的化学成分。
采用柱色谱法(硅胶、大孔树脂、葡聚糖凝胶LH - 20和制备型反相高效液相色谱)分离化合物。通过物理和光谱数据阐明其结构。
分离鉴定出8个化合物,分别为橘红素(1)、3 - O - β - D - 吡喃葡萄糖基桔梗皂苷元甲酯(2)、3 - O - β - D - 吡喃葡萄糖基桔梗酸A内酯(3)、3 - O - β - D - 吡喃葡萄糖基桔梗皂苷元(4)、去芹糖桔梗酸A内酯(5)、去芹糖桔梗皂苷D(6)、桔梗皂苷 - G1(7)和桔梗皂苷 - E(8)。
化合物1、3和5首次从该植物中分离得到。
