Micropropagation of Feverfew (Tanacetum parthenium) and Quantification of Parthenolide Content in Its Micropropagated and Conventionally Grown Plants

Feverfew (Tanacetum parthenium) is a well-known multi-functional plant with anti-inflammatory, cardiotonic, antiangiogenic, and anticancer effects. The therapeutic value of this plant is due to its phytochemical constitutes, especially parthenolide. Tissue culture techniques have been applied to improve the bioactive components of many herbal plants. Hence, this study, was carried out to establish a protocol for micropropagation of the feverfew plant and to quantify parthenolide content in its micropropagated and conventionally grown plants. To establish an aseptic culture, different concentrations of sodium hypochlorite (NaOCl) were investigated for seed surface sterilization. Besides, the effects of plant growth regulators (PGRs) on the callus induction, shoot organogenesis from callus and in vitro rooting were evaluated. Additionally, the parthenolide yield of the micropropagated and conventionally grown plants was determined by using high-performance liquid chromatography (HPLC). The results showed that surface sterilization of feverfew seeds with 6% NaOCl for 15 min obtained 65.00 ± 2.69% aseptic seeds. Murashige and Skoog (MS) medium supplemented with 0.4 mg/L thidiazuron (TDZ) and 2 mg/L 2,4-dichlorophenoxy acetic acid (2,4-D) resulted in 86.00 ± 1.72% callus induction. The highest number of shoots (5.00 ± 0.15) per explant was obtained in the treatment of MS medium supplemented with 5 mg/L zeatin. MS medium fortified with 3 mg/L indole-3-butyric acid (IBA) produced the maximum number of roots per plantlet (8.90 ± 0.35). A total of 90% of the micropropagated plantlets survived when planted in perlite + peat moss (1:1 v/v); the micropropagated plantlets were successfully established in the ex vitro conditions. According to parthenolide analysis, its level was significantly higher in the micropropagated plants than conventionally grown plants. Among different solvents, ethanolic extraction obtained the highest parthenolide content of the feverfew plant. Hence, it can be concluded that micropropagation of feverfew could be applied to produce disease-free planting materials and to improve the parthenolide content of the feverfew plant.

Application of Phytotests to Study of Environmental Safety of Biologicaly Synthetised Au and Au/ZnO Nanoparticles Using Tanacetum parthenium Extract

Due to their small sizes and high reactivity, nanoparticles have a completely different toxicity profile than larger particles, and it is difficult to predict their potential ecological impact. There is a need for broad ecotoxicological studies of nanomaterials in order to specify their environmental impact and ensure safe application of nanotechnology products. In this work, we have assessed the toxicity of Au and Au/ZnO metal nanoparticles obtained with the use of Tanacetum parthenium (herba) extract. The obtained nanoparticles were characterized by UV–Vis spectrophotometry (UV–VIS), Transmission electron microscopy (TEM), Atomic force microscopy (AFM), and Fourier transform infrared spectroscopy (FTIR). In order to assess the toxicity of biologically synthesized nanoparticles, we used seeds of various plants: Lepidium sativum, Linum flavum, Zea mays, Salvia hispanica-chia, Lupinus angustifolius, Petroselinum crispum subsp. Crispum, Beta vulgaris, Phaseolus vulgaris. The in vitro phytotests showed that gold nanoparticles at a specific range of concentrations for all plants stimulated their growth. The highest growth activity was exhibited by the solution at the concentration of 0.300 mg/ml towards corn (Aw ≈ − 135 ± 16) and flax (Aw ≈ − 44 ± 10). Only for parsley the IC50 was determined at 0.57 mg/ml, but solutions at the concentration of 0.030 to 0.150 mg/ml also stimulated plant growth. Au/ZnO had a toxic effect at all concentrations applied in the study.

Amelioration of Radiation-Induced DNA Damage and Immunosuppression by Tanacetum parthenium leaf extract and synthetic parthenolide in Swiss Albino Mice

Radiotherapy potentially offers protection from recurrence of tumor that also causes normal tissue damage and creates major concern. Another important factor is long-term immune suppression in patients treated with radiotherapy. Therefore, crucial need for the survival of surrounding normal cells of tumor by radiation‑protecting agents is the prime focus of this study. Aqueous extract (AE) and ethanolic extract (EE), Tanacetum parthenium extracts100 mg/kg each and parthenolide (PAR) 4mg/kg body weight were orally administered prior to sub-lethal radiation dose exposure. Mice were used for the evaluation of radiation-mediated chromosomal aberrations in bone marrow cells and DNA break by comet assay in the blood lymphocytes of mice. The pro-inflammatory levels were determined by cytokine estimations namely interleukin‑2, interferongamma and tumor necrosis factor-alpha performed in the liver homogenate using ELISA kits. Thus the results demonstrated ameliorating, radio-mitigating and immune-stimulatory efficacy of AE, EE and PAR against radiation ‑induced DNA damage and immunosuppression by regulating cytokine.

Background Tripleurospermum disciforme (C.A.Mey.) Sch.Bip., Tanacetum parthenium (L.) Sch.Bip., and Achillea biebersteinii Afan. are the most important species of the Asteraceae family that are used in traditional medicine as antiseptics, analgesics, and anti-ulcers. This study aimed to evaluate and compare the yield, chemical profile, and antibacterial and antifungal properties of the essential oils of these three species for the first time. For this purpose, plant materials were collected in June 2019 from Javinan region (Kashan, Iran). Results Based on the ANOVA results the species had a significant effect on yield, chemical composition, and diameter of the inhibition zone of some microorganisms (P ≤ 0.01). The highest yield belonged to T. disciforme essential oil (~ 1.433%). Analysis of essential oil compounds showed that in T. disciforme, anisole, p-1-cyclohexen-1-yl- (55.95%), modephene (10.00%), and cis-β-farnesene (11.94%), in T. parthenium, camphor (43.43%), camphene (9.40%), and bornyl acetate (6.76%), and in A. biebersteinii linalool (34.49%), p-cymene (15.31%), and α-terpineol (7.43%) were the main and predominant compounds. The highest inhibition zone diameter by the essential oil of T. parthenium and A. biebersteinii against Aspergillus brasiliensis (~ 13 mm) was observed. The strongest inhibitory and lethal activity was related to T. disciforme essential oil against Klebsiella pneumoniae, Shigella dysenteriae, Escherichia coli (~ 8.50 mm), and Candida albicans (MIC and MBC = 62.5 μg/mL), which were equivalent to rifampin and twice as potent as nystatin, respectively. Conclusions Therefore, the essential oil of the studied species of Asteraceae may be a promising and potential strategy for controlling some microorganisms and a possible natural alternative to some antibiotics.

Background and Aim: Medicinal plants contain various biological compounds, including phenols, flavonoids, and terpenoids, with anti-radical and anti-inflammatory activities that affect human health and improve life. Considering the numerous beneficial effects of Tanacetum Parthenium and Satureja Montana and the lack of full antioxidant capacity and anti-inflammatory effects of their combination, we decided to combine these two plants’ anti-inflammatory and antioxidant effects on induced acute inflammation in BALB/c mice. Methods & Materials: In the present study, mice received the extracts of T. Parthenium and S. Montana and their combination by gavage for 14 consecutive days. Then, to induce acute inflammation, thioglycollate was injected intraperitoneally to all groups. FRAP and Grease tests were used to evaluate the total antioxidant capacity and serum nitric oxide concentration, respectively. One-way ANOVA analyzed the results. Ethical Considerations: This study was approved by the Research Ethics Committee of Arak University of Medical Sciences (Code: REC.1398.021). Results: The results showed that the combination of the extracts (P=0.006) and Satureja Montana (P=0.021) led to a significant increase in total antioxidant activity compared to the control group. Also, according to the results of grease test, Satureja montana (P=0.04), Tanacetum parthenium (P=0.034), and their combination (P=0.003) significantly reduced serum nitric oxide production compared to the control group. Conclusion: The present study shows the synergistic effect of the combined extracts to increase their total antioxidant capacity and anti-inflammatory.

Mig-RL: a Natural Preventive Treatment Against Migraine. Outcomes of a Randomized, Double-Blind Clinical Trial

BACKGROUND The efficacy and safety of Mig-RL (Commercial name HERBA MIG), a synergistic association of two plant extracts, Tanacetum parthenium (150mg, 0.5% parthenolide) and Salix Alba (150mg, 25% salicin) were investigated as a preventive treatment for episodic migraine. Mig-RL was compared with a placebo in a randomized, double-blind clinical trial. MATERIALS AND METHODS This trial included 129 patients having episodic migraine and diagnosed with migraines without aura for over a year and meeting the migraine criteria, as defined in the International Classification of Headache Disorder (ICHD-3 :1.1). P). Baseline data was collected for 28 days before the start of the three-months treatment period. Patients were randomized in a 1:1 ratio to receive either Mig-RL (a single dose of 300mg per day, per os) or placebo (identical capsules containing 300 mg starch, 1 per day, per os) for a period of 12 consecutive weeks. The primary endpoint was the mean change in the average number of migraine days per month, comparing the baseline 28-days pre-intervention period with the weeks 9 to 12 after the first dose of the trial regimen. Secondary endpoints were the percentage of patients with a reduction of at least 30% in the average number of migraine days per month and days of use of any acute headache medication per month. The HIT-6 and MIDAS scores were also evaluated vs. baseline between the two groups. RESULTS Out of 172 patients enrolled, 129 were randomly assigned to the Mig-RL arm (n=65) or the placebo arm (n=64). The mean (±SD) number of baseline migraine days per month was 8.4±1.9 and 8.7±1.9, respectively. The mean reduction in the average number of migraine days per month was 2.5±0.4 (p<0.001) with Mig-RL and 1.9±0.4 (p<0.001) with placebo. A difference of 0.6±0.4 (p=0.01) between the two groups. The percentage of patients with at least 30% reduction in average number of migraine days per month was 49% in Mig-RL and 32% in placebo (p<0.05 vs. placebo). Only a few isolated and minor side effects were reported and overall Mig-RL was well tolerated by patients. CONCLUSIONS Mig-RL, a synergistic combination of two plant extracts, seems to have a moderate effect in the prevention of migraines. Without side effects, the combination of Tanacetum parthenium and Salix alba could be an additional help for some patients. However, further investigations and an improvement in the quality of the plants are still necessary.

Emulgel loaded with specific drugs has been found effective in some topical disorders, and it is emerging as potential drug delivery system in the area of dermatology. Since emu-lgel shows enhanced spreadability, adhesion, viscosity and extrusion. Based on the obtained results, an emulsion gel base was chosen as a carrier for a semi-solid drug with SSFE

Evaluation of Antimicrobial, Cytotoxicity and Catalytic Activities of CuO-NPs Synthesized by Tanacetum Parthenium Extract

Development of efficient methods for treating microbial infections, cancer, and toxic organic dyes is a serious challenge in medical sciences. The purpose of this study is to synthesize CuO-NPs using T. parthenium extract and to evaluate its anticancer, antimicrobial, and catalytic activity. CuO-NPs were characterized by UV-Vis, XRD, FTIR, FESEM, and EDX. UV-Vis spectra exhibited surface plasmonic resonance at 298 nm of synthesized CuO-NPs. The synthesized CuO-NPs were pure, predominantly spherical with mean size of 16 nm. FTIR confirmed that CuO-NPs were reducted and stabilized with the biomolecules present in the T. parthenium extract. CuO-NPs indicated excellent degradation activity for the industrial dyes, i.e., MO (96.6% removal in 400s), Rh B (98.3% removal in 400s), MB (98.7% removal in 400s) and CR (99.6% removal in 180s). CuO-NPs showed excellent inhibition against selected microorganisms, especially E.coli and C. albicans. CuO-NPs have also shown good anticancer activity against A549, Hela, and MCF7 cancer cell lines (IC50 = 65.0, 57.4, and 71.8 µg/mL, respectively) while negligible cytotoxic effects were observed on L929 (IC50 = 226.1 µg/mL). The results proposed that synthesized CuO-NPs can be considered as a suitable candidate for biomedical, pharmaceutical, and environmental applications.
