Qualitative and Quantitative Evaluation of Rosavin, Salidroside, and p-Tyrosol in Artic Root Products via TLC-Screening, HPLC-DAD, and NMR Spectroscopy.

ABSTRACT: Artic root is a well-known plant adaptogen with multipotential pharmacological properties. Thin-layer chromatography (TLC)-screening followed by diode-array high-performance liquid chromatography and nuclear magnetic resonance spectroscopy proved to be a reliable and convenient method for the simultaneous determination of the quality of various herbal raw materials and supplements. This combination allowed for comparing and differentiating arctic root samples as well as defining their authenticity. The study provided information on the chemical and biological properties of the seven chosen samples as well as qualitative and quantitative evaluation of the quality markers: rosavin, salidroside, and p-tyrosol. The absence of rosavin, salidroside, and p-tyrosol in three samples was detected using TLC screening and confirmed by HPLC-DAD and NMR. The paper highlighted the importance of quality control and strict regulation for herbal medicine supplements and preparations.

Project description:Salidroside is one of the major phenolic glycosides in Rhodiola, which has been reported to possess various biological activities. In the present study the in vivo deglycosylation metabolism of salidroside was investigated and its aglycone p-tyrosol but not the original salidroside was identified as the main form in rat tissues following the administration of salidroside. After the i.v. administration of salidroside at a dose of 50 mg/kg in rats, salidroside was quantified only in the liver, kidney and heart tissues. The highest level of p-tyrosol was detected in the heart, followed by the spleen, kidney, liver and lungs, in order. Salidroside was detected only in the liver, in contrast, p-tyrosol was detectable in most tissues except the brain, and the kidney tissues contained a significant amount of p-tyrosol compared to the other tissues after the i.g. administration of 100 mg/kg salidroside. The excretion behaviour revealed that the administrated salidroside mainly eliminated in the form of salidroside but not its aglycone metabolite p-tyrosol through urine. After i.v. and i.g. administration in rats, 64.00% and 23.80% of the total dose was excreted through urine in the form of salidroside, respectively. In addition, 0.19% and 2.25% of the dose was excreted in the form of p-tyrosol through urine after i.v. and i.g. administration, respectively. The faecal salidroside and p-tyrosol concentrations were 0.3% and 1.48% of the total dose after i.v. administration, respectively. After the i.g. administration of salidroside, trace salidroside and p-tyrosol were quantified in faeces within 72 h. In addition, the biliary excretion levels of salidroside after i.v. and i.g. administration were 2.86% and 0.02% of the dose, respectively. The obtained results show that salidroside was extensively metabolised to its aglycone p-tyrosol and distributed to various organs and the original salidroside was cleared rapidly through urine following the administration of salidroside.
