A study on the antioxidant, anti-inflammatory, and xanthine oxidase inhibitory activity of the Artemisia vulgaris L. extract and its fractions. JOURNAL OF ETHNOPHARMACOLOGY 2024; 334:118519. [PMID: 38971340 DOI: 10.1016/j.jep.2024.118519] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/22/2024] [Revised: 06/25/2024] [Accepted: 07/01/2024] [Indexed: 07/08/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Vietnamese people use mugwort (Artemisia vulgaris L.) to treat arthritis and gout. Our previous research shows that mugwort contains flavonoids, and its extract possesses antibacterial and anti-inflammatory activities. However, no publications have been on the xanthine oxidase inhibitory activity of mugwort and acute anti-inflammatory activity in vivo. AIM OF THE STUDY The study aimed to verify the antioxidant, xanthine oxidase inhibitory, and anti-inflammatory capabilities of mugwort extract in vitro and in vivo, isolate phyto-compounds from potential bioactive fractions, and then evaluate their potential in inhibiting xanthine oxidase. METHODS According to established methods, the extract and the active flavonoids were obtained using different chromatographic techniques. DPPH, ABTS, reducing power, and H2O2 elimination were used to evaluate antioxidant activity. The model of LPS-induced RAW264.7 cells was used to measure the inhibition of NO production. The carrageenan-induced paw oedema model was used to assess acute inflammation in mice. In vitro, xanthine oxidase inhibition assay was applied to investigate the effects of extract/compounds on uric acid production. Chemical structures were identified by spectral analysis. RESULTS The assessment of the acute inflammatory model in mice revealed that both the 96% ethanol and the 50% ethanol extracts significantly decreased oedema in the mice's feet following carrageenan-induced inflammation. 96% ethanol extract exhibited a better reduction in oedema at the low dose. The analysis revealed that the ethyl acetate fraction had the highest levels of total polyphenols and flavonoids. Additionally, this fraction demonstrated significant antioxidant activity in various assays, such as DPPH, ABTS, reducing power, and H2O2 removal. Furthermore, it displayed the most potent inhibition of xanthine oxidase, an anti-inflammatory activity. Five phytochemicals were isolated and determined from the active fraction such as luteolin (1), rutin (2), apigenin (3), myricetin (4), and quercetin (5). Except for rutin, the other compounds demonstrated the ability to inhibit effective xanthine oxidase compared to standard (allopurinol). Moreover, quercetin (5) inhibited NO production (IC50 21.87 μM). CONCLUSION The results indicate that extracts from A. vulgaris effectively suppressed the activity of xanthine oxidase and exhibited antioxidant and anti-inflammatory properties, potentially leading to a reduction in the production of uric acid in the body and eliminating ROS. The study identified mugwort extract and bioactive compounds derived from Artemisia vulgaris, specifically luteolin, apigenin, and quercetin, as promising xanthine oxidase inhibitors. These findings suggest that further development of these compounds is warranted. At the same time, the above results also strengthen the use of mugwort to treat gout disease in Vietnam.

Abstract
To cope with the constraints of conventional drug delivery systems, site-specific drug delivery systems are the major focus of researchers. The present research developed water-swellable, pH-responsive methacrylic acid-based hydrogel scaffolds of Artemisia vulgaris seed mucilage with mucin and loaded with acyclovir sodium as a model drug. The developed hydrogel discs are evaluated for diverse parameters. Drug loading efficiency in all formulations ranges from 63% to 75%. The hydrogels exhibited pH-dependent swelling, displaying optimum swelling in a phosphate buffer (pH 7.4), and insignificant swelling in an acidic buffer (pH 1.2), in addition, they responded well to electrolyte concentrations. The sol-gel fraction is estimated ranging from 60 to 95%. Dissolution studies unveiled sustained drug release for 24 h in a phosphate buffer of pH 7.4, exhibiting zero-order release kinetics. Moreover, FTIR spectra confirmed the drug-excipient compatibility. SEM photomicrographs revealed a rough and porous surface of hydrogel discs with several pores and channels. The PXRD diffractograms exposed the amorphous nature of the polymeric blends. The findings of acute toxicity studies proved the developed hydrogel network is biocompatible. Therefore, these outcomes connote the newly created network as a smart delivery system, able to dispatch acyclovir sodium into the intestinal segment for a prolonged period.

Artemvulactone E isolated from Artemisia vulgaris L. ameliorates lipopolysaccharide-induced inflammation in both RAW264.7 and zebrafish model. Front Pharmacol 2024; 15:1415352. [PMID: 39092222 PMCID: PMC11291208 DOI: 10.3389/fphar.2024.1415352] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2024] [Accepted: 07/04/2024] [Indexed: 08/04/2024] Open
Abstract
Introduction Natural plants are valuable resources for exploring new bioactive compounds. Artemisia vulgaris L. is a traditional Chinese medicinal herb that has been historically used for treating multiple diseases. Active compounds isolated and extracted from A. vulgaris L. typically possess immunomodulatory and anti-inflammatory properties. Artemvulactone E (AE) is a new sesquiterpene lactone isolated and extracted from A. vulgaris L. with unclear biological activities. Methods The immunoregulatory effects of AE on macrophages were assessed by ELISA, RT-qPCR, immunofluorescence, and western blot assay. The effect of AE on lipopolysaccharide (LPS) -relates signaling pathways was examined by western blot assay. In zebrafish models, the larvae were yolk-microinjected with LPS to establish inflammation model and the effect of AE was evaluated by determining the survival rate, heart rate, yolk sac edema size, neutrophils and macrophages infiltration of zebrafish. The interaction between AE and Toll-like receptor 4 (TLR4) was examined by molecular docking and dynamic stimulation. Results AE reduced the expression and secretion of pro-inflammatory cytokines (TNF-α and IL-6), inflammatory mediators iNOS and COX-2, as well as decreases the production of intracellular NO and ROS in LPS-stimulated macrophages. In addition, AE exerted its anti-inflammatory effect synergistically by inhibiting MAPK/JAK/STAT3-NF-κB signaling pathways. Furthermore, AE enhanced the survival rate and attenuated inflammatory response in zebrafish embryos treated with LPS. Finally, the molecular dynamics results indicate that AE forms stable complexes with LPS receptor TLR4 through the Ser127 residue, thus completely impairing the subsequent activation of MAPK-NF-κB signaling. Conclusion AE exhibits notable anti-inflammatory activity and represents as a potential agent for treating inflammation-associated diseases.

Abstract
Several medicinal plants have been administered to cancer patients attributed to their anticarcinogenic and chemoprotective properties, in addition to lower toxicity compared to traditional therapies. The aim was to investigate the antioxidant properties and carotenoid composition of aqueous extracts of Mentha piperita or Artemisia vulgaris which were previously found to exert beneficial effects on human health through diet. aqueous extracts exhibited potent antioxidant activity. A diversity of carotenoids was identified in these extracts using HPLC-PDA-MS/MS. Both extracts contained predominantly all-trans-lutein as the main component within this class. In order to investigate antioxidant properties, the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) techniques were used. The (3-4,5 dimethylthiazol-2, 5 diphenyl tetrazolium bromide) (MTT) and Crystal Violet assays assessed cellular cytotoxicity. Assessments of presence of reactive species were carried out following exposure of oral squamous cell carcinoma cell line (SCC-4) to various aqueous extracts of M piperita or A vulgaris utilizing dichlorofluorescein diacetate (DCFH-DA) and nitric oxide (NO) assays. Exposure to these extracts induced severe cytotoxic effects, which led to investigation of the biochemical and molecular mechanisms underlying this observed effect. Data demonstrated that both solutions induced oxidative stress and DNA damage, especially at higher concentrations using agarose gel subjected to electrophoresis. It is known that exposure to excess amounts of antioxidants results in a prooxidant effect which is beneficial in cancer therapy. Further, the extracts were found to reduce viability of SCC-4 in culture, indicating that this antitumoral activity may be of therapeutic importance and requires further study.

Abstract
This study aimed to evaluate the effect of aqueous and acetone extracts from Artemisia vulgaris L. (AV) and Artemisia alba Turra (AA), and two major polyphenols compounds (3,5-dihydroxybenzoic acid and quercetin-3-O-glucopyranoside) presented in both extracts of the plants against mitomycin C (MMC)-induced genomic instability. Genomic instability was measured using cytokinesis block micronucleus (MN) assay in human peripheral blood lymphocytes (PBLs) in vitro by analyzing two biomarkers - MN and nuclear division index (NDI). Extracts were tested in a concentration-dependent manner (10-250 µg/mL), while 3,5-dihydroxybenzoic acid and quercetin-3-O-glucopyranoside were tested in three different concentrations, in combination with 0.5 µg/mL of MMC. Aqueous and acetone extracts obtained from both plants significantly reduced MMC-induced MN frequency in PBLs, compared to positive control cells (p < 0.05). Extracts from AV did not affect NDI, whereas the concentrations of 10-100 μg/mL of aqueous and acetone AA extracts significantly elevated MMC-decreased NDI values in comparison to positive control cells (p < 0.05). Combined treatment of 3,5-dihydroxybenzoic acid and MMC showed a significant reduction of MMC-induced MN frequency, while quercetin-3-O-glucopyranoside increased MN frequency compared to positive control cells (p < 0.05). Both compounds decreased NDI values but only at the highest tested concentration of quercetin-3-O-glucopyranoside it was of greater significance. In conclusion, all extracts from AV and AA and 3,5-dihydroxybenzoic acid showed protective effect, whereby aqueous AA demonstrated the highest protective effect on MMC- induced genomic instability, while quercetin-3-O-glucopyranoside showed co-mutagen effect.

Abstract
The aim of this study was to evaluate the antibacterial activities of selected medicinal plant practices by a traditional healer of the Newar community in Itum Bahal, Kathmandu, Nepal. The antibacterial activities of the methanolic extract (1 mg/disc) of fifteen medicinal plants were screened against two Gram-positive bacteria (Staphylococcus aureus ATCC 25923 and Bacillus subtilis ATCC 6633) and two Gram-negative bacteria (Escherichia coli ATCC 25922 and Salmonella typhi CCM 5445) using the disc diffusion method. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were calculated for the different fractions (hexane, chloroform, ethyl acetate, acetonitrile, and acetone) of the plants having a significant antimicrobial effect. Only Quercus infectoria G. Olivier (galls) and Mallotus repandus (Willd.) Müll.Arg. (seeds) exhibited prominent antibacterial effects. The acetone fraction from Q. infectoria had the strongest antibacterial effect, with a 41.00 mm inhibition zone against S. aureus. In contrast, the ethyl acetate fraction in M. repandus exhibited the highest efficacy, producing a 29.00 mm inhibition zone against S. typhi. In a similar manner, in the case of Q. infectoria, the acetoe fraction depicted the lowest MIC (0.19 mg/mL) and MBC (0.98 mg/mL) values against S. aureus, whereas the ethyl acetate fraction of M. repandus was most significant, showing the lowest MIC and MBC of 0.25 and 0.53 mg/mL, respectively, against S. typhi. This study suggested that the acetone extract of Q. infectoria galls can be used as a potential source against Gram-positive bacteria, whereas the ethyl acetate extract of M. repandus seeds could serve as a useful source to inhibit Gram-negative bacteria. Furthermore, extensive scientific investigation is mandatory to ensure the proper use of folk medicines.

Abstract
Lychnis coronaria, a perennial (herbaceous) belonging to Caryophyllaceae has been traditionally used for treating different complications. However, the free radical scavenging effect, anti-inflammatory activity and anticancer property of methanolic extract of this plant has not been addressed. Most importantly, the chemical constituents present in the extract of Lychnis coronaria responsible for its diverse activities have not been scrutinized till date. Here, we used a complex approach for exploring the above mentioned effects of Lychnis coronaria. We performed rigorous phytochemical screening followed by quantification of tannins, phenols, alkaloids, quinones and sterols from the extract. Moreover we employed in vitro DPPH, ABTS , FRAP assay, albumin denaturation inhibition experiment, MTT assay, high resolution liquid chromatography mass spectrometry for measurng the reactive oxygen species quenching, anti-inflammatory and anticancer strength of Lychnis coronaria and for identifying the possible bioactive molecules. We identified two novel molecules panaxynol (polyacetylenic alcohol) and norharman (9H-Pyrido [3, 4-B] indole) following rigorous analysis of the extract. Following this, the binding affinity of these molecules was estimated using human cyclooxygenase (COX)-2 enzyme as target. Among the constituents of Lychnis coronaria norharman manifested stronger binding towards COX-2 compared to panaxynol. Most importantly, norharman showed high stability in the groove of COX2 as confirmed by molecular dynamics simulation. Collectively, Lychnis coronaria manifested free radical neutralizing, inflammation soothing and anticancer effect in concentration dependent manner and thus may serve as a promising phytotherapeutic in future.Communicated by Ramaswamy H.

Terpenoids and Bio-Functions of Essential Oils Hydrodistilled Differently from Freshly Immature and Mature Blumea balsamifera Leaves. J Trop Med 2023; 2023:5152506. [PMID: 36926419 PMCID: PMC10014153 DOI: 10.1155/2023/5152506] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Revised: 01/27/2023] [Accepted: 02/14/2023] [Indexed: 03/09/2023] Open
Abstract
The volatiles and antioxidant capacity of essential oils (EOs) extracted from freshly immature and mature leaves of Blumea balsamifera at various hydrodistillation times were investigated. Seven major terpenoids were identified: two monoterpenes, camphor and L-borneol, and five sesquiterpenes, silphiperfol-5-ene, 7-epi-silphiperfol-5-ene, ß-caryophyllene, ɤ-eudesmol, and α-eudesmol. The quantity and terpenoid composition of the EOs were impressed by leaf maturity and hydrodistillation times. The yield of EOs from the immature leaves was 1.4 times that of mature leaves, with 73% of the yield acquired within the first 6 hours (hrs) of hydrodistillation. Approximately 97% of camphor and L-borneol, 80% of ß-caryophyllene, silphiperfolene, and 7-epi-silphiperfolene, 32% of ɤ-eudesmol, and 54% α-eudesmol were collected in the first 6 hrs of hydrodistillation. More ß-caryophyllene, ɤ-eudesmol, and α-eudesmol were found in the mature leaf EOs. The antioxidant capacity of the EOs was proportionally related to their terpenoid contents. The EOs extracted from immature leaves at 0-6 hrs of hydrodistillation demonstrated distinctive antibacterial activity against Staphylococcus aureus, with minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values of 0.5 mg/mL and 1 mg/mL, respectively.

Abstract
Our study was designed to screen the antibacterial potency of Princepia utilis leaf and seed extract and to measure their antioxidant effects, total phenol content, total flavonoid content, and total carbohydrate content. Collected samples were extracted by cold maceration. Hexane, ethyl acetate, methanol, and distilled water were used as extraction solvents. In the disc diffusion method, P. utilis ethyl acetate leaf extract was most prominent against Staphylococcus epidermis with a zone of inhibition (ZOI) of 13.83 mm. Similarly, methanolic leaf extract was most prominent against Staphylococcus aureus (ZOI-12.33 mm). Furthermore, the methanolic seed extract was most sensitive against Klebsiella pneumoniaee (ZOI-11.66 mm) Escherichia coli (ZOI-9.0 mm). The lowest minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values of 0.5 mg/mL and 0.6 mg/mL, respectively, were shown by ethyl acetate leaf extract against S. epidermis. Similarly, the highest values of MIC and MBC, i.e., 20.8 mg/mL and 33.3 mg/mL, respectively, were shown by hexane leaf extract against S. epidermidis. On the other hand, evaluation of antioxidant capacity revealed that ethyl acetate leaf extract showed the maximum antioxidant effect (IC50: 66.69 μg/mL). The total flavonoid contents of different extracts were measured in the range of 37 ± 0.74 μg QE/mg dry extract weight (methanolic seed extract) to 321.84 ± 4.82 μg QE/mg dry extract weight (hexane seed extract). Likewise, the total polyphenol content ranged from the hexane leaf extract (17.33 ± 0.642 μg GAE/mg dry extract weight) to ethyl acetate leaf extract (62.56 ± 1.284 μg GAE/mg dry extract weight). We found a variation in total carbohydrate content in the range of 23.55 ± 1.125 μg glucose/mg dry extract weight (hexane leaf extract) to 96.63 ± 2.253 μg glucose/mg dry extract weight (aqueous leaf extract). Overall, this study revealed that leaf and seed extract of P. utilis exhibited noteworthy antibacterial effects against diverse pathogenic microorganisms.
