Figure 4

The lower layer of ethyl acetate soluble fraction from Maackia amurensis was isolated with Sephadex LH-20 and isolated compounds were monitored by HPLC analysis at 254 nm. (a) The lower layer of EtOAc fraction from M. amurensis. (b) Isolated compounds; peak 1, chlorogenic acid; peak 2, formononetin-7-O-β-D-glucosyl glucoside; peak 3, trans-ferulic acid; peak 4, tectoridin.
