Rhodiosin and herbacetin in Rhodiola rosea preparations: additional markers for quality control?
Pharm Biol 2019 Dec;57(1):295-305.PMID:31356124DOI:10.1080/13880209.2019.1577460.
Context: Rhodiola rosea L. (Crassulaceae) is well-known to contain flavonoids such as the herbacetin derivative Rhodiosin. However, flavonoids are not typically used in quality control. Objective: This study analyses two flavonoids of R. rosea rhizomes and roots for their potential as analytical markers. Materials and methods: Two constituents were isolated from ethanolic extracts via HPLC, identified via NMR and quantified via RP-HPLC. Presence and content variation was investigated according to extraction (solvent and repetitions), drying (temperature and duration) and sample origin (homogenously cultivated plants of different provenance, commercial samples). Results: Rhodiosin was identified as a main flavonoid, accompanied by 10-fold lower concentrated herbacetin. Both compounds were best extracted with 70-90% ethanol, but were also detectable in more aqueous extracts. Different drying conditions had no effect on the flavonoid content. These two flavonoids were consistently identified in rhizome and root extracts of over 100 R. rosea samples. Rhizomes tend to contain less flavonoids, with average ratios of rosavins to flavonoids of 1.4 (rhizomes) and 0.4 (roots). Provenance differences were detected in the range (Rhodiosin plus herbacetin) of 760-6300 µg/mL extract corresponding to a maximum of approximately 0.5-4.2% (w/w) in the dry drug. Conclusions: For the first time, two main flavonoids present in R. rosea were quantified systematically. Rhodiosin and herbacetin can be detected simultaneously to phenylpropenoids or salidroside in authentic samples, influenced by the plant part examined and the plant origin. Rhodiosin and herbacetin may serve as additional marker to guarantee a consistent content of R. rosea products.
Insights into the direct anti-influenza virus mode of action of Rhodiola rosea
Phytomedicine 2022 Feb;96:153895.PMID:35026524DOI:10.1016/j.phymed.2021.153895.
Background: The anti-influenza A virus activities and contents of previously isolated most active flavonoids (Rhodiosin and tricin) from a standardized hydro-ethanolic R. rosea root and rhizome extract (SHR-5®), did not fully explain the efficacy of SHR-5®. Moreover, the mode of antiviral action of SHR-5® is unknown. Purpose: To determine the anti-influenza viral principle of SHR-5® we evaluated i) the combined anti-influenza virus effect of Rhodiosin and tricin, ii) the impact of its tannin-enriched fraction (TE), iii) its antiviral spectrum and mode of action, and iv) its propensity for resistance development in vitro. Methods: The combined anti-influenza virus effect of Rhodiosin and tricin and the impact of TE were investigated with cytopathic effect (CPE)-inhibition assays in MDCK cells. A tannin-depleted fraction (TD) and TE were prepared by polyamide column chromatography and dereplicated by LC-MS. Plaque-reduction assays provided insights into the anti-influenza virus profile, the mode of action, and the propensity for resistance development of SHR-5®. Results: Our results i) did not reveal synergistic anti-influenza A virus effects of Rhodiosin and tricin, but ii) proved a strong impact of TE mainly composed of prodelphinidin gallate oligomers. iii) TE inhibited the plaque-production of influenza virus A(H1N1)pdm09, A(H3N2), and B (Victoria and Yamagata) isolates (including isolates resistant to neuraminidase and/or M2 ion channel inhibitors) with 50% inhibitory concentration values between 0.12 - 0.53 µg/ml similar to SHR-5®. Mechanistic studies proved a virucidal activity, inhibition of viral adsorption, viral neuraminidase activity, and virus spread by SHR-5® and TE. iv) No resistance development was observed in vitro. Conclusion: For the first time a comprehensive analysis of the anti-influenza virus profile of a hydro-ethanolic R. rosea extract (SHR-5®) was assessed in vitro. The results demonstrating broad-spectrum multiple direct anti-influenza virus activities, and a lack of resistance development to SHR-5® together with its known augmentation of host defense, support its potential role as an adaptogen against influenza virus infection.
Two potent cytochrome P450 2D6 inhibitors found in Rhodiola rosea
Pharmazie 2013 Dec;68(12):974-6.PMID:24400445doi
Objectives: Throughout the world, in particular in Russia, Northern Europe and China, Rhodiola species are used as herb supplements. Previously, we found that the extract of Rhodiola rosea, one of the most widely used Rhodiola species, had an inhibitory effect on the catalytic activity of cytochrome P450 2D6. Here, its inhibitory components were identified. Methods: A human liver microsomal in vitro system was used with dextromethorphan as substrate. The production rate of destrorphan, a metabolite of dextromethorphan, was used to measure enzyme activity. The concentration of destrorphan in the samples was measured using LC-MS/MS. Inhibitory activity of eight main components from Rhodiola rosea was evaluated. Results: Rhodiosin and rhodionin showed inhibitory activity with IC50 values of 0.761 microM and 0.420 microM, respectively. The other components showed no obvious inhibition (with a residual enzyme activity of more than 90%). Both Rhodiosin and rhodionin were determined to be non-competitive inhibitors with Ki values of 0.769 microM and 0.535 microM. Conclusion: Two of the main Rhodiola rosea compounds, Rhodiosin and rhodionin, can inhibit cytochrome P450 2D6 non-competitively with high specificity which could have implications for interactions with co-administered drugs.
High-performance Countercurrent Chromatography to Access Rhodiola rosea Influenza Virus Inhibiting Constituents
Planta Med 2021 Aug;87(10-11):818-826.PMID:32781473DOI:10.1055/a-1228-8473.
In a cytopathic effect inhibition assay, a standardized Rhodiola rosea root and rhizome extract, also known as roseroot extract (SHR-5), exerted distinct anti-influenza A virus activity against HK/68 (H3N2) (IC50 of 2.8 µg/mL) without being cytotoxic. For fast and efficient isolation and identification of the extract's bioactive constituents, a high-performance countercurrent chromatographic separation method was developed. It resulted in a three-stage gradient elution program using a mobile phase solvent system composed of ethyl acetate/n-butanol/water (1 : 4 : 5 → 2 : 3 : 5 → 3 : 2 : 5) in the reversed-phase mode. The elaborated high-performance countercurrent chromatographic method allowed for fractionation of the complex roseroot extract in a single chromatographic step in a way that only one additional orthogonal isolation/purification step per fraction yielded 12 isolated constituents. They cover a broad polarity range and belong to different structural classes, namely, the phenylethanoid tyrosol and its glucoside salidroside, the cinnamyl alcohol glycosides rosavin, rosarin, and rosin as well as gallic acid, the cyanogenic glucoside lotaustralin, the monoterpene glucosides rosiridin and kenposide A, and the flavonoids tricin, tricin-5-O-β-D-glucopyranoside, and Rhodiosin. The most promising anti-influenza activities were determined for Rhodiosin, tricin, and tricin-5-O-β-D-glucopyranoside with IC50 values of 7.9, 13, and 15 µM, respectively. The herein established high-performance countercurrent chromatographic protocol enables fast and scalable access to major as well as minor roseroot constituents. This is of particular relevance for extract standardization, quality control, and further in-depth pharmacological investigations of the metabolites of this popular traditional herbal remedy.
Salidroside orchestrates metabolic reprogramming by regulating the Hif-1α signalling pathway in acute mountain sickness
Pharm Biol 2021 Dec;59(1):1540-1550.PMID:34739769DOI:10.1080/13880209.2021.1992449.
Context: Rhodiola crenulata (Hook. f. et Thoms.) H. Ohba (Crassulaceae) is used to prevent and treat acute mountain sickness. However, the mechanisms underlying its effects on the central nervous system remain unclear. Objective: To investigate the effect of Rhodiola crenulata on cellular metabolism in the central nervous system. Materials and methods: The viability and Hif-1α levels of microglia and neurons at 5% O2 for 1, 3, 5 and 24 h were examined. We performed the binding of salidroside (Sal), Rhodiosin, tyrosol and p-hydroxybenzyl alcohol to Hif-1α, Hif-1α, lactate, oxidative phosphorylation and glycolysis assays. Forty male C57BL/6J mice were divided into control and Sal (25, 50 and 100 mg/kg) groups to measure the levels of Hif-1α and lactate. Results: Microglia sensed low oxygen levels earlier than neurons, accompanied by elevated expression of Hif-1α protein. Salidroside, Rhodiosin, tyrosol, and p-hydroxybenzyl alcohol decreased BV-2 (IC50=1.93 ± 0.34 mM, 959.74 ± 10.24 μM, 7.47 ± 1.03 and 8.42 ± 1.63 mM) and PC-12 (IC50=6.89 ± 0.57 mM, 159.28 ± 8.89 μM, 8.65 ± 1.20 and 8.64 ± 1.42 mM) viability. They (10 μM) reduced Hif-1α degradation in BV-2 (3.7-, 2.5-, 2.9- and 2.5-fold) and PC-12 cells (2.8-, 2.8-, 2.3- and 2.0-fold) under normoxia. Salidroside increased glycolytic capacity but attenuated oxidative phosphorylation. Salidroside (50 and 100 mg/kg) treatment increased the protein expression of Hif-1α and the release of lactate in the brain tissue of mice. Conclusions: These results suggest that Sal induces metabolic reprogramming by regulating the Hif-1α signalling pathway to activate compensatory responses, which may be the core mechanism underlying the effect of Rhodiola crenulata on the central nervous system.
