中文摘要:目的:研究红参皂苷在人尿液的排泄。方法:成年人(62 kg体质量)口服红参提取物2 g(相当于4.30 g红参),然后分别在0~3、3~6、6~12、12~24 h收集尿液。通过超快速液相-串联质谱法(UFLC-MS/MS)技术与对照品比较分析鉴定和定量人参皂苷的排泄。结果:在人24 h排泄的尿液中,可检测到3个苷元,即20(S)-原人参三醇(PPT)、20(R)-PPT和20(S)-原人参二醇(PPD);7个人参皂苷(G),即20(S)-G-Rh1、G-Rd、G-Rk3、G-Rh4、20(S)-G-Rg3、20(R)-G-Rg3和G-C-K。结论:红参中的一些原型人参皂苷及其代谢产物可通过人体尿液排出体外。 |

Abstract:Objective:To study the urine excretion of ginsenosides from red ginseng in man. Methods:An adult with body weight of 62 kg was orally given 2 g (equivalent to 4.30 g of red ginseng) of red ginseng water extract. Then,the urine samples were collected at 0-3 h,3-6 h,6-12 h,12-24 h post-dosing,respectively,which were analyzed and identified for excreted ginsenoside and their metabolites by ultra-fast liquid chromatography coupled with MS/MS method and comparison with standard substances. Results:In the excreted urine during 24 h post-dosing,3 aglycones namely 20(S)-protopanaxatriol,20(R)-protopanaxatriol and 20(S)-protopanaxadiol,and 7 ginsenosides namely 20(S)-ginsenoside-Rh1,ginsenoside-Rd,ginsenoside-Rk3,ginsenoside-Rh4,20(S)-ginsenoside-Rg3,20(R)-ginsenoside-Rg3 and ginsenoside-compound-K were detected and identified. Conclusion:Some prototypical ginsenosides and their metabolites in red ginseng could be excreted by urine in man. |
