Chemical Profiling and Screening of the Marker Components in the Fruit of by HPLC and UHPLC/LTQ-Orbitrap MS with Chemometrics.

L. which is known as “Golden Shower”, is used as an ornamental plant due to its flowers, and fruit parts of this plant have a high medicinal value. There are few reports providing a comprehensive overview of the chemical composition of its fruit or explaining the differences between samples from different sources because of the complexity of its chemical components.

[Intestinal absorption of Ginseng Radix et Rhizoma extract combined with Acori Tatarinowii Rhizoma in rats].

To investigate the changes in intestinal absorption of ginsenosides Rg₁, ginsenosides Re and ginsenosides Rd after combined administration of Ginseng Radix et Rhizoma extract and Acori Tatarinowii Rhizoma, in order to confirm whether the combined administration is scientific and rational, and provide experimental basis for pharmaceutical studies of the formula. An in vivo single-pass perfusion method was performed to study the effect of various concentrations of ginsenosides Rg₁, ginsenosides Re, ginsenosides Rd on the intestinal absorption at duodenum, jejunum, ileum and colon. The concentrations of ginsenosides Rg₁, ginsenosides Re, ginsenosides Rd were determined by RP-HPLC.
