Abstract
This work aimed to investigate the intestinal absorption characteristics of Laportea bulbifera extract in normal and rheumatoid arthritis model rats. The contents of neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, rutin, kaempferol-3-O-rutinoside, galuteolin, quercetin and isoquercetin in intestinal absorption solution samples were detected by UPLC-MS/MS with 5.0 g·L~(-1) as the absorption concentration. The cumulative absorption(Q) and absorption rate constant(K_a) were calculated, and the absorption characteristics of different components of L. bulbifera in intestinal absorption solution of normal rats and rheumatoid arthritis rats were compared. The results showed that all the eight index components in the extract of L. bulbifera could be absorbed into the intestinal capsule, the cumulative absorption-time curve of each component showed an upward trend without saturation, and the correlation regression coefficient(R~2) was greater than 0.92, which is consistent with the zero-order absorption rate process. It was speculated that the possible absorption mode of each component was passive diffusion. In normal condition, the absorption of ileum was the best(except chlorogenic acid), and in pathological condition, duodenum was the best. The total absorption of 8 components in each intestinal segment of RA rats was better than that of normal rats, which speculated that rheumatoid arthritis may change the specific site of drug absorption. The experimental results showed that rheumatoid arthritis could change the intestinal absorption of the extract of L. bulbifera, and its mechanism needs further study.

Abstract
The everted gut sacs and Caco-2 cell models were used to investigate the intestinal absorptive characteristics and subcellular localization of chitobiose and chitopentaose in this study. In everted gut sacs, the absorptive pattern showed no concentration-dependent manner when the concentration was lower than 10 mM. In the presence of phlorizin (100 μM) and phloretin (100 μM), the chitobiose absorption rates decreased by (4.97 ± 0.89)% and (19.2 ± 2.77)%, and they were (10.4 ± 2.43)% and (27.5 ± 1.68)% for chitopentaose. In Caco-2 cells, the concentration showed influences similar to those with the everted gut sacs results. After adding phlorizin and phloretin in the apical side, the PappAP-BL of chitobiose and chitopentaose significantly decreased. Considering the translocation, they were enriched in endoplasmic reticulum and mitochondrion. This study indicated that concentration and active transporter were capable of mediating the absorption of chitobiose and chitopentaose, and the subcellular localization of them could help to study the mechanisms of their effects.
