Abstract:
Objective Explore changes in polysaccharides in Jiangxiangru before and after ginger juice preparation,and evaluate polysaccharide anti-inflammatory and antioxidant activities before and after processing.Methods The contents of Jiangxiangru polysaccharide(JXRPs)and Ginger juice processed of Jiangxiangru polysaccharide(JZJXRPs)before and after processing were determined by phenol-sulfuric acid method.We used the swelling model in rats and endotoxin(LPS)to establish the RAW264.7 mouse macrophage inflammation model.The optimal administration concentration was determined using a cell proliferation(MTT)assay.Enzyme-linked immunosorbent assay(ELISA)were used to measure Interleukin-6(IL-6),Interleukin-12(IL-12),Nitric oxide(NO),Interleukin-4(IL-4),and Interleukin-10(IL-10).Bleeding time of mice by tail cutting was observed to evaluate the hemostatic effect.The ability to remove 1,1-diphenyl-2-picryl-hydrazyl radical(DPPH)and 2,2'-Azinobis-(3-ethylbenzthiazoline-6-sulphonate)(ABTS)was used to evaluate in vitro antioxidant activity.Results The contents of JXRPs and JZJXRPs were 13％and 22％,respectively.In swollen rats at 4 h after injection,compared with the model group,200 mg/kg JXRPs and 100 mg/kg JZJXRPs significantly reduced rat swelling(P＜0.05).In vitro anti-inflammation assessment showed that the polysaccharides before and after processing significantly inhibited secretion of IL-6,IL-12,and NO(P＜0.01)and promoted secretion of IL-4 and IL-10(P＜0.01),and also that processing post-effects were stronger.The hemostatic experiment show that,compared with the control group,JXRPs increased hemostasis,but without a significant difference,and no significant difference was found using JZJXRPs,although high doses showed a trend to increase hemostasis.In vitro antioxidant activity showed that JXRPs and JZJXRPs had different scavenging abilities for DPPH and ABTS with IC50 values of JXRPs of 0.2215 and 0.2110 mg/ml,respectively,and IC50 values of JZJXRPs of 0.1651 and 0.1884 mg/mL,respectively.Conclusions After Jiangxiangru is produced in ginger juice,it promotes dissolution of polysaccharides and increases polysaccharide content.Anti-inflammatory,hemostasis,and antioxidant capacities are stronger in JZJXRPS than JXRPS,which lays the foundation for follow-up research and clinical applications of JXRPS.
