Abstract:

To prepare Chinese medicine plant extracts replacing feed antibiotics. Firstly, Grana Pericarpium, Cinnamomi Ramulus, Magnoliae officinalis cortex, Artemisiae annuae herba, Spatholobi caulis were sieved from 19 Chinese medicine plants as materials of extract compounds by examining antibacterial rate, inhibitory rateanti-inflammatory rate, and antioxidant IC50 value as evaluating index. Secondly, proportions of five materials were optimized by a L16 (4 5) orthogonal experiment,by range analysis of results, three extract compounds with the strongest antibacterial (Fab), anti-inflammatory (Fai) and antioxidant (Fao) activities were obtained. These material ratios of Magnoliae officinalis cortex, Spatholobi caulis, Artemisiae annuae herba, Cinnamomi Ramulus and Grana Pericarpium were 7∶13∶6∶9∶1 in Fab, 7∶13∶4∶1∶1 in Fai, and 3∶13∶4∶1∶7 in Fao, respectively. Finally, the verifying results showed that the minimum inhibitory concentration of Fab was 125 mg·mL-1, the anti-inflammatory IC50 value of Fai was 0.144 mg·mL-1, and the antioxidant IC50 value of Fao was 0.222 mg·mL-1. In summary, the present study obtained the best three Chinese medicine extract compounds with stronger antibacterial, anti-inflammatory and antioxidant effects, respectively.
