ABSTRACT
This article was aimed to study the intestinal absorption about main active ingredients of pectolinarin and pectolinarigenin in Carboned Cirsium japonicum DC. The absorption rate and absorption rate constant were taken as indicators. The intestinal absorption of pectolinarin and pectolinarigenin were compared by everted rat intestinal sac method among different parts of the small intestine. The results showed that the absorption rate constant of pectoli-narin among duodenum, jejunum, ileum and colon parts were 0.505 1 ± 0.192 7, 0.936 0 ± 0.187 2, 0.732 0 ±0.133 5, 0.251 3 ± 0.027 6 (μg·h-1·cm-2). The absorption rate constant of pectolinarigenin among the duodenum, je-junum, ileum and colon were 0.059 1 ±0.008 3, 0.093 3 ±0.029 2, 0.112 3 ± 0.035 6, 0.029 4 ± 0.009 1 (μg·h-1·cm-2). It was concluded that the absorption of both ingredients increased over time. The absorption of both ingredi-ents in the jejunum and ileum was higher than other parts of the small intestine. The absorption rate of pectolinarin in the entire small intestine was much higher than the absorption rate of pectolinarigenin.
