Fufang Danshen preparation (FDP) is consisted of Salviae Miltiorrhizar Radix et Rhizoma (Danshen),Notoginseng Radix et Rhizoma (Sanqi) and Borneolum Syntheticum (borneol).FDP is usually used to treat myocardial ischemia hypoxia,cerebral ischemia and alzheimer's disease,etc.In the treatment of cerebrovascular diseases,borneol is usually used to promote the absorption and distribution of the bioactive components to proper organs,especially to the brain.The purpose of this study is investigating the effects of borneol on the pharmacokinetics and brain distribution of tanshinone ⅡA (TS ⅡA),salvianolic acid B (SAB) and ginsenoside Rgl in FDP.Male healthy Sprague-Dawley (SD) rats were given Danshen extracts,Sanqi extracts (Panax notoginseng saponins) or simultaneously administered Danshen extracts,Sanqi extracts and borneol.Plasma and brain samples were collected at different points in time.The concentration of TS ⅡA,SAB and Rg1 was determined by UPLC-MS/MS method.The main pharmacokinetics parameters of plasma and brain tissue were calculated by using Phoenix WinNolin 6.1 software.In comparison with Danshen and Sanqi alone,there were significant differences in pharmacokinetic parameters of TS ⅡA,SAB and Rg1,and the brain distribution of SAB and TS ⅡA when Danshen,Sanqi and borneol were administrated together.Bomeol statistically significant shortened tmax of TS ⅡA,SAB and Rgl in plasma and brain,increased the bioavaiability of Rg1,inhibited metabolism of Rgl and enhanced the transport of TS ⅡA and SAB to brain.These results indicated that borneol could affect the multiple targets components and produce synergistic effects.Through accelerating the intestinal absorption and brain distribution,borneol caused the effective ingredients of Danshen and Sanqi to play a quicker therapeutic role and improved the therapeutic effect.
