Simultaneous Determination of Seven Phenolic Acids in Rat Plasma Using UHPLC-ESI-MS/MS after Oral Administration of Echinacea purpurea Extract.

ABSTRACT: A rapid and sensitive Ultra High Performance Liquid Chromatography Electrospray Ionization Tandem Mass Spectrometry (UHPLC-ESI-MS/MS) method was developed and validated to simultaneously determine the concentration of seven phenolic acids (syringic acid, ferulic acid, caffeic acid, vanillic acid, p-coumaric acid, 3,4-dihydroxybenzoic acid and 4-hydroxybenzoic acid) in rat plasma after oral administration of Echinacea purpurea extract. After mixing with the internal standard (IS), butylparaben, plasma samples were prepared by liquid-liquid extraction with ethyl acetate. The separation was performed using the Agilent Eclipse Plus C₁₈ column (1.8 ?m, 2.1 mm × 50 mm) with a gradient system consisting of solution A (0.1% acetic acid in water) and solution B (methanol) at a flow rate of 0.3 mL/min. The detection was accomplished by a multiple reaction monitoring (MRM) mode with electrospray ionization (ESI). The method was validated in terms of linearity, precision, accuracy, extraction recovery, matrix effect and stability. This method was successfully applied to study the pharmacokinetic properties of the seven compounds after oral administration of Echinacea purpurea extract in rats.

Project description:A selective and sensitive ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method was developed and validated for the determination of ziyuglycoside I (I), 3?,19?-dihydroxyurs-12-en-28-oic-acid 28-?-d-glucopyranosyl ester (II), 3?-[(?-l-arabinopyranosyl) oxy]-urs-12,18(19)-dien-28-oic acid ?-d-glucopyranosyl ester (III), rosamultin (IV), 1?-hydroxyeuscaphic acid (V) and alpinoside (VI) in rats after oral administration of Sanguisorba officinalis L. (S. officinalis) extract. The 3?,19?-dihydroxyurs-12-en-28-oic-acid 28-?-d-glucopyranosyl ester, 3?-[(?-l-arabinopyranosyl) oxy]-urs-12,18(19)-dien-28-oic acid ?-d-glucopyranosyl ester, rosamultin, 1?-hydroxyeuscaphic acid and alpinoside in rat plasma were the first report in the pharmacokinetics study in the present study. The analytes were quantified using the multiple reaction monitoring (MRM) mode with the electrospray ion source in positive electrospray ionization. Plasma was extracted with ethyl acetate via liquid?liquid extraction. Bifendate was used as internal standard (IS). The current method was validated for linearity, intra-day and inter-day precisions, accuracy, extraction recovery, matrix effect and stability. The lower limits of quantification of ziyuglycoside I, 3?,19?-dihydroxyurs-12-en-28-oic-acid 28-?-d-glucopyranosyl ester, 3?-[(?-l-arabinopyranosyl) oxy]-urs-12,18(19)-dien-28-oic acid ?-d-glucopyranosyl ester, rosamultin, 1?-hydroxyeuscaphic acid and alpinoside were 6.1, 4.9, 1.3, 3.8, 1.5 and 5.7 ng/mL, respectively. Intra-day and inter-day precision and the accuracy of the assay were in range from -9.48 to 12.74%. The extraction recoveries of analytes and bifendate (IS) from rat plasma ranged from 77.17% to 92.48%. Six compounds could be rapidly absorbed into blood (Tmax, 0.58?1.58 h), and then eliminated relatively slowly (t1/2, 6.86?11.63 h). The pharmacokinetic results might contribute to further guide the clinical application of S. officinalis.

Project description:Associations of salicylate-like phenolic glycosides (PGs) with biological activity have been reported in Salix and Populus trees, but only for a few compounds, and in relation to a limited number of herbivores. By considering the full diversity of PGs, we may improve our ability to recognize genotypes or chemotype groups and enhance our understanding of their ecological function. Here, we present a fast and efficient general method for salicylate determination in leaves of Eurasian aspen that uses ultra-high performance liquid chromatography-electrospray ionization/time-of-flight mass spectrometry (UHPLC-ESI/TOFMS). The time required for the liquid chromatography separations was 13.5 min per sample, compared to around 60 min per sample for most HPLC protocols. In leaf samples from identical P. tremula genotypes with diverse propagation and treatment histories, we identified nine PGs. We found the compound-specific mass chromatograms to be more informative than the UV-visible chromatograms for compound identification and when quantitating samples with large variability in PG content. Signature compounds previously reported for P. tremoloides (tremulacin, tremuloidin, salicin, and salicortin) always were present, and five PGs (2'-O-cinnamoyl-salicortin, 2'-O-acetyl-salicortin, 2'-O-acetyl-salicin, acetyl-tremulacin, and salicyloyl-salicin) were detected for the first time in P. tremula. By using information about the formic acid adduct that appeared for PGs in the LTQ-Orbitrap MS environment, novel compounds like acetyl-tremulacin could be tentatively identified without the use of standards. The novel PGs were consistently either present in genotypes regardless of propagation and damage treatment or were not detectable. In some genotypes, concentrations of 2'-O-acetyl-salicortin and 2'-O-cinnamoyl-salicortin were similar to levels of biologically active PGs in other Salicaceous trees. Our study suggests that we may expect a wide variation in PG content in aspen populations which is of interest both for studies of interactions with herbivores and for mapping population structure.

Project description:Fuzi-Gancao herb couple is one of the commonly used herb couples involved in the traditional Chinese medicine formulations, with radix aconiti lateralis (Fuzi in Chinese) and radix glycyrrhizae (Gancao in Chinese) as a ratio of 1:1. Alkaloids and flavonoids were considered as the main active ingredients of Fuzi-Gancao herb couple. However, no analytical methods have been reported to quantitatively analyze these activity ingredients in Fuzi-Gancao herb couple simultaneously.To develop a simple, rapid, and sensitive UHPLC-MS/MS method for simultaneous quantitation of six alkaloid and three flavonoid compounds, namely, aconitine (AC), mesaconitine (MA), hypaconitine (HA), benzoylaconitine (BAC), benzoylmesaconitine (BMA), benzoylhypaconitine (BHA), liquiritin, isoliquiritin, and licochalcone A (LCA) in Fuzi-Gancao herb couple.The chromatographic separation was achieved using a reversed phase C18 column and a mobile phase consisted of water (0.1% formic acid in water, v/v) and acetonitrile. The detection was achieved in multiple reaction monitoring modes. The optimal mass transition ion pairs (m/z) for quantitation were 646.3/586.5 for AC, 632.4/572.5 for MA, 616.3/556.4 for HA, 604.5/572.5 for BAC, 590.4/540.4 for BMA, 574.1/542.5 for BHA, 419.4/257.1 for liquiritin, 419.4/257.1 for isoliquiritin, and 339.2/121.1 for LCA.Good linearity was observed in validated concentration range for each analyte (r > 0.9992), and the intra- and inter-day precisions were <3.12% and 3.65%, respectively. The recovery ranged from 85.36% to 110.14%.The results demonstrated that the method developed was reliable, rapid, and specific. Moreover, this method was successfully applied to control the quality of Fuzi-Gancao herb couple.A simple, rapid, and sensitive UHPLC-MS/MS method for simultaneous quantitation of six alkaloid and three flavonoid compounds in Fuzi-Gancao herb couple has been developed.
