Anti-allergic rhinitis effects of caffeoylquinic acids from the fruits of Xanthium strumarium in rodent animals via alleviating allergic and inflammatory reactions

Abstract The fruits of Xanthium strumarium L., Asteraceae, have been used for various diseases in Chinese folk medicine, including allergic rhinitis, tympanitis, arthritis, ozena etc. The current study was aimed to investigate the therapeutic effects of caffeoylquinic acids from fruits of X. strumarium on allergic rhinitis in animals. The toxicity test indicated that the caffeoylquinic acids have no obvious toxicity. By using HPLC assays combined with reference standards, ten caffeoylquinic acids were identified as the predominant constituents. Anti-allergic activities of the caffeoylquinic acids were evaluated using passive cutaneous anaphylaxis test and Schultz-Dale test; dimethylbenzene induced ear edema test was performed to evaluate its anti-inflammatory effect. Then, the allergic rhinitis model in rats was established to evaluate the therapeutic effects of the caffeoylquinic acids against allergic rhinitis with the following indexes: allergic rhinitis symptom scores, serum levels of pro-inflammatory cytokines, histopathological examination, and histamine release. Our study revealed that the caffeoylquinic acids showed obvious anti-allergic and anti-inflammatory properties, and its treatments were beneficial for ameliorating the nasal symptoms, decreasing pro-inflammatory cytokines, and inhibiting the releases of histamine. Collectively, the caffeoylquinic acids might be utilized as effective and safe disease therapeutic agents for allergic rhinitis.
