Effects of Rutin Combined with Quercetin with Different Compatibility Ratios on the Pharmacokinetics of Rutin in Rats in vivo
摘要
Abstract
OBJECTIVE:To explore the effects of the different compatibility ratios of rutin with quercetin on the pharmacoki-netics of rutin in rats in vivo. METHODS:30 rats were randomly divided into rutin group(rutin-quercetin molar ratio of 4:0,the same below),quercetin group(rutin-quercetin ratio of 0:4),BL1 group(rutin-quercetin ratio of 3:1),BL2 group(rutin-quercetin ratio of 2:2)and BL3 group(rutin-quercetin ratio of 1:3),6 rats in each group,all group was administrated 10 mg/kg(calculat-ed by quercetin core of rutin and quercetin) intragastrically. The blood sample 0.3 mL was respectively taken from tail vein after 0.25,0.5,0.75,1,1.5,2,3,4,6,8,10,12,16,20,24 h of administration,the plasma concentration of quercetin(rutin me-tabolite) was determined by HPLC. DAS 2.0 software was used to calculate the pharmacokinetic parameters. RESULTS:The AUC0-24 h in rutin group,quercetin group,BL1 group,BL2 group and BL3 group were (4.908 ± 0.877),(8.382 ± 3.671), (8.473 ± 0.709),(4.366 ± 2.297),(8.914 ± 2.642)μg·h/L;MRT0-24 h were (9.675 ± 1.359),(3.142 ± 0.489),(3.517 ± 1.128), (3.376 ± 1.046),(4.494 ± 1.653) h;tmax were (5.726 ± 5.645),(1.375 ± 0.703),(1.125 ± 1.438),(1.417 ± 2.300),(1.292 ± 0.954) h;and cmax were (0.609 ± 0.202),(2.341 ± 0.539),(2.425 ± 1.217),(1.464 ± 0.677),(3.325 ± 2.425)μg/L. Compared with rutin group,AUC0-24 h and cmax in quercetin group,BL1 group and BL3 group were significantly increased(P<0.05),tmax and MRT0-24 h were significantly decreased(P<0.05);cmax in BL2 group was significantly increased(P<0.05),tmax and MRT0-24 h were significantly decreased(P<0.05). Compared with quercetin group,except AUC0-24 h was significantly decreased in BL2 group(P<0.05),there were no significant differences in AUC0-24 h,MRT0-24 h,tmax or cmax in BL1 group,BL2 group and BL3 group(P>0.05). CONCLUSIONS:Quercetin can inhance the related indexes of rutin in rats in vivo.关键词
