Results The ethanol extracts 0.48 gkg^(-1, macroporous resin eluate of aqua 0.3 gkg^(-1 and the further purification 0.1, 0.3 gkg^(-1 could hasten gastric emptying in mice. Furthermore, they restrained the inhibition of dopamine on gastric emptying in mice. They had no effect on the inhibition of atropine.

结果 醇提物0.48gkg^(-1、大孔树脂水洗脱物0.3gkg^(-1及继续纯化物01、0.3gkg^(-1对正常小鼠的胃排空有促进作用，并可拮抗多巴胺引起的小鼠胃排空的抑制作用，而对阿托品引起的小鼠胃排空抑制作用无影响。

Of our predecessors by improving extraction technology, used solid-phase extraction way to extract a separation, that is, the AB-8 macroporous resin for solid phase, ethanol - water eluate, through multiple-eluting And constantly improve the preparation of conditions, from the extract of red flowers in the isolated flavonoids components.

SiO2 opal with face centered cubic structure is fabricated using a self-assembly method. Two different three-dimensionally ordered macroporous carbon materials are prepared using SiO2 opal as a template through "volume templating" and "surface templating" approaches, respectively. The final morphology of the sample can he controlled by the infiltration times.
