Quantitation of ligupurpurosides B and C in rat plasma using HPLC-MS/MS
Chin J Nat Med 2016 Jun;14(6):473-80.PMID:27473966DOI:10.1016/S1875-5364(16)30045-0.
The present study was designed to develop a sensitive and selective specific high performance liquid chromatography (HPLC)-tandem mass spectrometric method (MS/MS) for the determination of ligupurpurosides B and C in rat plasma. The samples were prepared after protein precipitation and analyzed by liquid chromatography equipped with a C18 column interfaced with a triple quadrupole tandem mass spectrometer using ESI as the ionization source in the negative ion mode. The mobile phase consisted of water (0.01 % formic acid)-methanol (57 : 43, V/V) at the flow rate of 0.3 mL·min(-1). The analytes and internal standard acteoside were both detected by use of multiple reaction monitoring mode. The total run time was 6.0 min. The method was linear in the concentration range of 2.5-500.0 ng·mL(-1) and the lower limit of quantifiation (LLOQ) was 2.5 ng·mL(-1). The intra-day and inter-day relative standard deviations across three validation runs over the entire concentration range were less than 9.8 %. The accuracy determined at three concentrations was within ± 6.1% in terms of relative error. In conclusion, this assay offers advantages in terms of expediency and suitability for the analysis of ligupurpuroside B and Ligupurpuroside C in various biological fluids.
Hypolipidemic activity and mechanisms of the total phenylpropanoid glycosides from Ligustrum robustum (Roxb.) Blume by AMPK-SREBP-1c pathway in hamsters fed a high-fat diet
Phytother Res 2018 Apr;32(4):715-722.PMID:29468762DOI:10.1002/ptr.6023.
The aim of this study was to evaluate the hypolipidemic effect and mechanisms of total phenylpropanoid glycosides extracted from Ligustrum robustum (Roxb.) Blume (LRTPG) in hamsters fed a high-fat diet and to discover bioactive components in HepG2 cell model induced by oleic acid. LRTPG of high (1.2 g/kg), medium (0.6 g/kg), and low (0.3 g/kg) doses was administrated daily for 21 consecutive days in hamsters. We found that in hamsters fed a high-fat diet, LRTPG effectively reduced the concentrations of plasma triglycerides (TG), free fatty acid, total cholesterol, low-density lipoprotein cholesterol, and hepatic TG and total cholesterol. And the compounds acteoside, ligupurpuroside A, Ligupurpuroside C, and ligupurpuroside D significantly inhibited lipid accumulation in HepG2 cell at the concentration of 50 μmol/L. Mechanism research demonstrated that LRTPG increased the levels of phospho-AMP-activated protein kinase and phospho-sterol regulatory element binding protein-1c in liver, further to suppress the downstream lipogenic genes as stearoyl-CoA desaturase 1, glycerol-3-phosphate acyltransferase, 1-acylglycerol-3-phosphate O-acyltransferase 2, and diacylglycerol acyltransferase 2. In addition, LRTPG increased the hydrolysis of circulating TG by up-regulating lipoprotein lipase activities. These results indicate that LRTPG prevents hyperlipidemia via activation of hepatic AMP-activated protein kinase-sterol regulatory element binding protein-1c pathway.
