Abstract:

Platycodon grandiflorum has "direct medicines ascending" action documented in the ancient Chinese medicinal book. For studying medicinal direct theory of Platycodon grandiflorum, we have added Platycodon grandiflorum on chicken’s drinking water, and then injected tilmicosin in order to investigate the effect of Platycodon grandiflorum on concentration of tilmicosin residues in lung tissues. We have offered drinking water containing different concentrations of Platycodon grandiflorum to experimental chickens for 4 weeks, and then the control group and experimental group were injected tilmicosin. Tilmicosin was extracted from lung tissues and detected by using high performance liquid chromatography (HPLC). The results showed that Platycodon grandiflorum can improve tilmicosin concentration in chicken lung tissue. These results conformed that Platycodon grandiflorum does have "direct medicines ascending" property.
