A sensitive LC-MS/MS-based bioanalytical method for quantification of Salviaflaside and rosmarinic acid in rat plasma and its application in a pharmacokinetic study

Biomed Chromatogr 2018 Aug;32(8):e4259.PMID:29655233DOI:10.1002/bmc.4259.

A selective and sensitive liquid chromatography tandem mass spectrometry method was developed for the simultaneous determination of Salviaflaside and rosmarinic acid in rat plasma. Sample preparation was carried out through liquid-liquid extraction with ethyl acetate using curculigoside as internal standard (IS). The analytes were determined by selected reaction monitoring operated in the positive ESI mode. Chromatographic separation was performed on an Agilent Eclipse Plus C18 column (100 × 4.6 mm, 1.8 μm) with a mobile phase consisting of methanol-water-formic acid (50:50:0.1, v/v/v) at a flow rate of 0.3 mL/min. The run time was 1.9 min per sample and the injection volume was 5 μL. The method had an LLOQ of 1.6 ng/mL for Salviaflaside and 0.94 ng/mL for rosmarinic acid in plasma. The linear calibration curves were fitted over the range of 1.6-320 ng/mL for Salviaflaside and 0.94-188 ng/mL for rosmarinic acid in plasma with correlation coefficients (r2 ) >0.99. Intra- and inter-day precisions (relative standard deviation) were < 13.5%, and accuracies (relative error) were between -8.6% and 14.5% for all quality control samples. The method was validated and applied to the pharmacokinetics of Salviaflaside and rosmarinic acid in plasma after oral administration of Prunella vulgaris extract to rats.

Screening out the anti-insomnia components from Prunella vulgaris L. based on plasma pharmacochemistry combined with pharmacodynamic experiments and UPLC-MS/MS analysis

J Ethnopharmacol 2021 Oct 28;279:114373.PMID:34181959DOI:10.1016/j.jep.2021.114373.

Ethnopharmacological relevance: Prunella vulgaris L. (P. vulgaris) is a medicinal plant belonging to the Labiatae family, and its dried spikes is called as Xiakucao in China, which is a common traditional Chinese medicine with the activities of clearing the liver and expelling fire, improving eyesight, dispersing nodules and detumescence. Modern pharmacological studies have proved that P. vulgaris has various pharmacological activities such as immunomodulatory, antiviral, antibacterial and anti-insomnia activities. Aims of this review: P. vulgaris have been reported to have anti-insomnia effects. Nevertheless, the pharmacodynamic substance basis of this anti-insomnia effect is still unclear. The aim of this study was to identify the active components responsible for evoking the anti-insomnia effect of P. vulgaris and to evaluate its anti-insomnia effect. Materials and methods: In this study, we proposed a method combined with pharmacodynamic experiments, extraction and enrichment of chemical components, and the plasma pharmacochemistry to screen out the anti-insomnia components of P. vulgaris. Firstly, the active eluted fraction of the ethanol extract was screened out based on pharmacodynamic tracing method, and then the chemical composition was analyzed systematically by UPLC-MS/MS. Thirdly, pharmacodynamic tracing method and silica gel column chromatography were employed to screen out the active fraction of 70% ethanol eluted fraction, and its bioactive components in vitro and in vivo were identified by UPLC-MS/MS. Finally, screening out the anti-insomnia components of P. vulgaris by comparing the difference between in vivo and in vitro components, and three potentially bioactive ingredients were validated experimentally. Results: It was confirmed that the fraction eluted with 70% ethanol from macroporous adsorption resin column was responsible for the anti-insomnia efficacy, and 55 compounds were identified or preliminarily identified. Then totally 9 compounds in vitro and 12 compounds in vivo from the active fraction of 70% ethanol eluted fraction were tentatively identified. Among them, mangiferin, rosmarinic acid and Salviaflaside were the prototype components of P. vulgaris, which indicated that the three compounds might play the key role in the anti-insomnia activities. In vivo, compared to blank control group, the three compounds significantly shortened the sleeping latency and prolonged the sleeping time produced by pentobarbital sodium. Conclusions: This study clarified that mangiferin, rosmarinic acid and Salviaflaside were considered as the anti-insomnia components of P. vulgaris. This is the first study on screening out the active ingredients responsible for evoking the anti-insomnia effect of P. vulgaris. The three compounds of P. vulgaris may help develop one or more drugs to prevent or treat insomnia. Further investigations are recommended to define the mechanism of the anti-insomnia activity of P. vulgaris.

Effects of UV-B Radiation on the Content of Bioactive Components and the Antioxidant Activity of Prunella vulgaris L. Spica during Development

Molecules 2018 Apr 24;23(5):989.PMID:29695057DOI:10.3390/molecules23050989.

The effects of UV-B radiation on the content of bioactive components and the antioxidant activity of Prunella vulgaris L. spica during development were studied. The experimental design involved two levels of UV-B radiation intensity (0 and 120 μW cm-2 nm-1). The results showed that the contents of total flavonoids, rosmarinic acid, caffeic acid and hyperoside, as well as the antioxidant capacities (DPPH● and ABTS•+ scavenging activities), in the spicas significantly decreased during spica development. The content of Salviaflaside in the spicas significantly increased during development. The highest contents of total flavonoids, rosmarinic acid, and caffeic acid and the highest antioxidant activities were found in spicas in the full-flowering stage, while the highest content of hyperoside was found in spicas in the bud stage. In addition, the highest content of Salviaflaside was found in spicas in the mature-fruiting stage. UV-B radiation significantly promoted the synthesis of secondary metabolites, increased the contents of the main bioactive components in the three developmental stages of isolated dried spicas, and significantly increased the DPPH● and ABTS•+ scavenging activities of P. vulgaris spicas in the mature-fruiting stage. Moreover, the total flavonoids content was positively correlated with the DPPH● and ABTS•+ scavenging activities, and the correlation with the DPPH● scavenging activity was very strong. This result shows that the highest contents of the main bioactive components in the spicas were not all found in the same developmental stages of P. vulgaris. Our research revealed that the best stage for harvesting P. vulgaris spica was between the bud stage and the full-flowering stage since harvesting at this point provides a higher content of bioactive components and a higher antioxidant capacity, which is relevant for medicinal applications.

[Exploration on feasibility of introducing bioassay method into quality evaluation of Chinese herbal medicines by studying on the correlation between antioxidant activity of Prunella vulgaris and its total phenolic acids content for example]

Zhongguo Zhong Yao Za Zhi 2016 Jul;41(14):2660-2668.PMID:28905603DOI:10.4268/cjcmm20161416.

This paper aims to investigate the correlation between the antioxidant activity of Prunella vulgaris and its total phenolic acids content by measuring the antioxidant activity of different sources and different organs of P. vulgaris and the total contents of protocatechuic acid, protocatechuic aldehyde, caffeic acid, Salviaflaside and rosmarinic acid in these samples. Using the 50% methanol extract of P. vulgaris samples as the research object, DPPH method and HPLC method were used respectively to determine the antioxidant activities and the total contents of the above-mentioned five analytes in P. vulgaris samples. 0.5 mL of 50% methanol extract of P. vulgaris reacts with 0.1 mmol•L⁻¹ DPPH ethanol solution for 60 min, then the absorbance of the reaction solution was measured at 517 nm, scavenging rate and IC₅₀ values were calculated by the absorbance and the sample concentration for evaluating the antioxidant activity. HPLC analysis was made on a C₁₈ Epic column, with acetonitrile-0.1% formic acid aqueous solution as mobile phase (gradient elution), and the detection wavelength was set at 280 nm. The correlation between the antioxidant capacity of different habitats and different organs of P. vulgaris and the total contents of five kinds of phenolic acids was analyzed by partial least squares method. The reaction dose-response range of 50% methanol extract of P. vulgaris with 0.1 mmol•L⁻¹ DPPH ethanol solution was 0.300-1.65 g•L⁻¹. When the quantities of potocatechuic acid, protocatechuic aldehyde, caffeic acid, Salviaflaside and rosmarinic acid were respectively in 0.007 84-0.980, 0.011 5-1.44, 0.008 64-1.08, 0.080 0-1.00 and 0.079 8-0.998 μg range, their quantities were in good linear relationship with the corresponding peak areas. The average recovery of 5 components were 97.76%, 96.88%, 100.3%, 102.1%, 104.5%, with RSD of 1.8%, 1.6%, 1.7%, 1.6% and 1.7%, respectively. In a certain range of crude drug quantity, the antioxidant activity of each organ of P. vulgaris and total phenolic acids content inside has a good linear correlation. Therefore, in certain quality range of crude drug, DPPH bioassay combined with HPLC content determination can be used for the quality control of P. vulgaris, as is a new method for the quality control of P. vulgaris.

Comparative study of seventeen Salvia plants: aldose reductase inhibitory activity of water and MeOH extracts and liquid chromatography-mass spectrometry (LC-MS) analysis of water extracts

Chem Pharm Bull (Tokyo) 1998 Mar;46(3):500-4.PMID:9549892DOI:10.1248/cpb.46.500.

The dry root and rhizome of Salvia miltiorhiza (Lamiaceae) are used as a crude drug Danshen, while those of S. deserta (Xinjiang-Danshen) are mixed in Danshen at Xinjiang province when the former is in short supply. The water and MeOH extracts of S. deserta showed strong aldose reductase (AR) inhibitory activity, and their active constituents were determined to be polar compounds different from "tanshinones" of S. miltiorhiza, i.e., lithospermic acid B (1), salvianolic acid K (2), Salviaflaside (3), and rosmarinic acid (4) (IC50, 2.63-3.91 microM). We also examined the AR inhibitory activity of water and MeOH extracts of seventeen Salvia plants, including ten species of Danshen resources (S. bowleyana, S. deserta, S. miltiorhiza, S. miltiorhiza var. miltiorhiza f. alba, S. paramiltiorhiza, S. paramiltiorhiza f. purpureo-rubra, S. przewalskii, S. przewalskii var. mandarinorum, S. sinica f. purpurea, S. trijuga), and their water extracts were also analyzed by liquid chromatography-mass spectrometry (LC-MS). The results indicated that there were four types with regard to the AR inhibitory activity and three types with regard to the amount of 1. Ten species used as Danshen resources showed good correlation between the AR inhibitory activity and the morphological classification. However, the intensities of their AR inhibitory activity varied, and they contained 1 in varying amounts. These facts suggested that the ten species were not the same, and thus their use as a Danshen resource should be based on their activity and/or active constituents.
