Posted by The pharmacokinetic characteristics of Hyperoside-2-hydroxypropyl-β-cyclodextrin inclusion complex in rats were evaluated. Compared with Hyperoside, the results showed that maximum plasma concentration and AUC0-t indexes of Hyperoside inclusion complex in rat plasma were increased, the value of half-life time was prolonged, and the value of apparent clearance was decreased, which proved that Hyperoside complexed with 2-hydroxypropyl-β-cyclodextrin could improve its bioavailability and increase its blood concentration. Secondly, the therapeutic effect of Hyperoside before and after complexing was further compared through the dextran sodium sulfate-induced colitis in mice. The experimental results showed that under the same dose, the Hyperoside inclusion complex had a better therapeutic effect, which could significantly increase the body weight of mice, improve the disease activity index, alleviate colon shortening, improve pathological colon changes, and have a better protective effect on colitis mice. According to 16S rDNA sequencing analyses, Hyperoside-2-hydroxypropyl-β-cyclodextrin may have an anti-inflammatory effect by increasing the abundance of beneficial bacteria (e.g. Firmicuria) and decreasing the proportion of harmful bacteria (e.g. Bacteroidetes) to balance the colon’s microbiota.
