However, little is known about the chemical and metabolic profiles of danshen in vitro or in vivo. In particular, more information is needed in relation to the 50% ethanol extracts usually used in danshen formulations such as Fufang Xueshuantong Capsules and Fufang Danshen tablets. High-performance liquid chromatography coupled with a linear ion trapOrbitrap mass spectrometer（HPLC-LTQ-Orbitrap） provides a sensitive and accurate method for analyzing the composition of samples. This method was used to determine the in vitro and in vivo chemical and metabolic profiles of danshen. Sixty-nine components of danshen extract and 118 components of danshen in rat plasma, urine, feces, and bile were unambiguously or tentatively identified. These results not only revealed the material composition of danshen, but also provided a comprehensive research approach for the identification of multi-constituents in TCMs.展开更多

Panax notoginseng （Burkill） F.H. Chen （PN） is the main herb of FXT, whose major bioactive constituents are ginsenosides. However, the scientific basis of the compatibility of FXT is still ambiguous. The present study investigated the scientific basis of the compatibility of FXT by comparing the pharmacokinetics of marker compounds after oral administrations of PN and FXT. A high performance liquid chromatography-electrospray ionization tandem mass spectrometry （HPLC-ESI-MS/MS） method was devel- oped for simultaneous detection of notoginsenoside R1 （NR1）, ginsenoside Rgl （GRgl）, and ginsenoside Rbl （GRbl） in rat plasma. The pharmacokinetic studies of FXT and PN were performed using the established method with the pharmacokinetic parameters being determined by non-compartmental analysis. The results showed that the phar- macokinetic parameters （maximum concentration, area under the curve （AUC0-t）, clearance, and mean residence time） of NR1, GRgl, and GRbl were significantly different after oral administration of FXT （P〈0.05） compared with PN. The AUO0-t values of GRgl and GRbl were 1.7- and 3.4-fold greater, respectively, in FXT than in PN. The compatible herbs of FXT could prolong the retention time and increase the systemic exposure of NR1, GRgl, and GRbl compared with PN in vivo, providing some scientific basis for the compatibility and clinical use of FXT.展开更多
