Exploring the composition and properties of Centella asiatica metabolites and investigating their impact on BSA glycation, LDL oxidation and α-amylase inhibition. J Pharm Biomed Anal 2024; 245:116143. [PMID: 38678859 DOI: 10.1016/j.jpba.2024.116143] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Revised: 03/26/2024] [Accepted: 03/31/2024] [Indexed: 05/01/2024]
Abstract
Centella asiatica (L.) Urb. is a small herbaceous plant belonging to the Apiaceae family that is rich in triterpenes, such as asiaticoside and madecassoside. Centella asiatica finds broad application in promoting wound healing, addressing skin disorders, and boosting both memory and cognitive function. Given its extensive therapeutic potential, this study aimed not only to investigate the Centella asiatica ethanolic extract but also to analyze the biological properties of its organic fractions, such as antioxidant antiglycation capacity, which are little explored. We also identified the main bioactive compounds through spectrometry analysis. The ethanolic extract (EE) was obtained through a static maceration for seven days, while organic fractions (HF: hexane fraction; DF: dichloromethane fraction; EAF: ethyl acetate fraction; BF: n-butanol fraction and HMF: hydromethanolic fraction) were obtained via liquid-liquid fractionation. The concentration of phenolic compounds, flavonoids, and tannins in each sample was quantified. Additionally, the antiglycation (BSA/FRU, BSA/MGO, and ARG/MGO models) and antioxidant (FRAP, ORAC, and DPPH) properties, as well as the ability to inhibit LDL oxidation and hepatic tissue peroxidation were evaluated. The inhibition of enzyme activity was also analyzed (α-amylase, α-glycosidase, acetylcholinesterase, and butyrylcholinesterase). We also evaluated the antimicrobial and cytotoxicity against RAW 264.7 macrophages. The main compounds present in the most bioactive fractions were elucidated through ESI FT-ICR MS and HPLC-ESI-MS/MS analysis. In the assessment of antioxidant capacity (FRAP, ORAC, and DPPH), the EAF and BF fractions exhibited notable results, and as they are the phenolic compounds richest fractions, they also inhibited LDL oxidation, protected the hepatic tissue from peroxidation and inhibited α-amylase activity. Regarding glycation models, the EE, EAF, BF, and HMF fractions demonstrated substantial activity in the BSA/FRU model. However, BF was the only fraction that presented non-cytotoxic activity in RAW 264.7 macrophages at all tested concentrations. In conclusion, this study provides valuable insights into the antioxidant, antiglycation, and enzymatic inhibition capacities of the ethanolic extract and organic fractions of Centella asiatica. The findings suggest that further in vivo studies, particularly focusing on the butanol fraction (BF), may be promising routes for future research and potential therapeutic applications.

Miconia albicans (Melastomataceae) to treat Chikungunya viral infection: An effectual symptom-driven ethnomedicinal repurposing of an anti-inflammatory species? JOURNAL OF ETHNOPHARMACOLOGY 2024; 318:116875. [PMID: 37451491 DOI: 10.1016/j.jep.2023.116875] [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: 03/21/2023] [Revised: 06/21/2023] [Accepted: 07/01/2023] [Indexed: 07/18/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Miconia albicans (MA) is consumed all over the Brazilian territory as a remedy to treat rheumatoid arthritis and has been increasingly used to alleviate the deleterious symptoms caused by Chikungunya virus (CHIKV). AIM OF THE STUDY To investigate the effect of MA leaf and stem hydroethanolic extracts (LE and SE, respectively), their fractions enriched in triterpene acids or polyphenols as well isolated constituents, on CHIKV hosted in Vero cells. MATERIALS AND METHODS Polyphenol profiles of LE and SE were dereplicated by HPLC-DAD-ESI-MS/MS, aided by standards. Polyphenol-rich (LEx and SEx) and triterpenic acid-rich (LOH and SOH) fractions were obtained in Amberlite XAD-4 and alkalinized 95% ethanol (EtOH) extraction, respectively. TPC and TFC were assessed by colorimetric methods. Three representative flavonoids and two triterpenic acids were quantified by HPLC. CHIKV load suppression was evaluated in Vero cells by real-time qRT‒PCR at noncytotoxic concentrations. RESULTS Fifteen flavonoids were characterized in LE and SE. LEx presented isoquercitrin, quercitrin, rutin (0.49-1.51%) and quercetin. The TPC was 48 and 62 mg QE/g extract, and the TFC was 11.93 and 0.76 mg QE/g extract for LEx and SEx, respectively. LOH presented ursolic (15.3%) and oleanolic (8.0%) acids. A reduction (91-97%) in the CHIKV load was produced by the triterpene fraction, quercitrin and quercetin; the latter maintained the activity down to one twentieth of the tolerated concentration. CONCLUSION M. albicans contains flavonoids and triterpenic acids that are effective against CHIKV, which might justify its use to alleviate sequelae of CHIKV infection. However, further investigations on the species and its active constituents are needed.

Abstract
BACKGROUND Given the rising occurrence of antibiotic resistance due to the existence and ongoing development of resistant bacteria and phenotypes, the identification of new treatments and sources of antimicrobial agents is of utmost urgency. An important strategy for tackling bacterial resistance involves the utilization of drug combinations, and natural products derived from plants hold significant potential as a rich source of bioactive compounds that can act as effective adjuvants. This study, therefore, aimed to assess the antibacterial potential and the chemical composition of Miconia albicans, a Brazilian medicinal plant used to treat various diseases. METHODS Ethanolic extracts from leaves and stems of M. albicans were obtained and subsequently partitioned to give the corresponding hexane, chloroform, ethyl acetate, and hydromethanolic phases. All extracts and phases had their chemical constitution investigated by HPLC-DAD-MS/MS and GC-MS and were assessed for their antibiofilm and antimicrobial efficacy against Staphylococcus aureus. Furthermore, their individual effects and synergistic potential in combination with antibiotics were examined against clinical strains of both S. aureus and Acinetobacter baumannii. In addition, 10 isolated compounds were obtained from the leaves phases and used for confirmation of the chemical profiles and for antibacterial assays. RESULTS Based on the chemical profile analysis, 32 compounds were successfully or tentatively identified, including gallic and ellagic acid derivatives, flavonol glycosides, triterpenes and pheophorbides. Extracts and phases obtained from the medicinal plant M. albicans demonstrated synergistic effects when combined with the commercial antibiotics ampicillin and ciprofloxacin, against multi-drug resistant bacteria S. aureus and A. baumannii, restoring their antibacterial efficacy. Extracts and phases also exhibited antibiofilm property against S. aureus. Three key compounds commonly found in the samples, namely gallic acid, quercitrin, and corosolic acid, did not exhibit significant antibacterial activity when assessed individually or in combination with antibiotics against clinical bacterial strains. CONCLUSIONS Our findings reveal that M. albicans exhibits remarkable adjuvant potential for enhancing the effectiveness of antimicrobial drugs against resistant bacteria.

Infusion from Miconia albicans (Melastomataceae) leaves exhibits anti-inflammatory and anti-hyperalgesic activities without toxicity. JOURNAL OF ETHNOPHARMACOLOGY 2023; 308:116251. [PMID: 36791930 DOI: 10.1016/j.jep.2023.116251] [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: 11/01/2022] [Revised: 02/02/2023] [Accepted: 02/06/2023] [Indexed: 06/18/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The leaves of Miconia albicans have been extensively used as a traditional medicine to treat inflammation, infection, arthritis, joint pain, and analgesia, which can be purchased easily. Nevertheless, the scientific evidence of chemical profile identification and toxicity investigation is meager. AIM OF THE STUDY This study aimed to determine the chemical profile of Miconia albicans aqueous extract (MAAE), to investigate its anti-inflammatory and hyperalgesic effects, and toxicity (acute and repeated-dose oral) in vivo studies. MATERIALS AND METHODS MAAE was obtained by infusion method and its chemical constituents were analyzed and annotated by LC-DAD-MS. The in vivo tests were performed with male and female Swiss mice. Toxicity studies were examined by acute (2000 mg/kg) and repeated-dose oral assays (51.2; 256; 1280 mg/kg); anti-inflammatory evaluation was performed by paw edema and leukocyte migration, and anti-hyperalgesic properties were analyzed by abdominal writhing induced by acetic acid and formalin. The animals were treated by oral means with 51.2, 256, and 1280 mg/kg of MAAE. RESULTS Twenty-four compounds were annotated from MAAE by LC-DAD-MS, such as ellagitannins, ellagic acid derivatives, flavan-3-ol, and O-glycosylated compounds, including flavonols, triterpenes, and megastigmanes. MAAE induced no significant toxicological effects in the acute and repeated-dose oral assays at lower doses and no histological changes were observed. Hematological and biochemical showed no significant alterations. The oral administration of MAAE 256 mg/kg inhibited the edematogenic effect and reduced the leukocyte migration. In addition, MAAE decreased the abdominal writhings induced by acetic acid and the paw-licking time by formalin assay. CONCLUSION MAAE showed a significant reduction in inflammatory levels and leukocyte migration, revealing anti-hyperalgesic properties. Additionally, MAAE revealed no acute and repeated-doses toxicities.

Abstract
The Miconia genus is traditionally used in folk medicine in Brazil and other tropical American countries and is represented by 282 species in this region. It is a multifaceted genus of medicinal plants widely used to treat rheumatoid arthritis (RA), pain, inflammatory diseases, and many more therapeutic applications. In the present study, we systematically identify and discuss the literature on in vivo and in vitro studies focusing on the therapeutic potentials and related molecular mechanisms of the Miconia genus. The review also assessed phytochemicals and their pharmacological properties and considered safety concerns related to the genus. Literature searches to identify studies on the Miconia genus were carried out through four main electronic databases, namely PubMed, Embase, Scopus, and Web of Science limited to Medical Subjects Headings (MeSH) and Descriptores en Ciencias de la Salud (DCS) (Health Sciences Descriptors) to identify studies published up to December 2022. The relevant information about the genus was gathered using the keywords 'Miconia', 'biological activities', 'therapeutic mechanisms', 'animal model, 'cell-line model', 'antinociceptive', 'hyperalgesia', 'anti-inflammatory', and 'inflammation'. The therapeutic potentials and mechanisms of action of 14 species from genus Miconia were examined in 18 in vitro studies and included their anti-inflammatory, anticancer, analgesic, antibacterial, cytotoxic, mutagenic, antioxidant, anti-leishmanial, antinociceptive, schistosomicidal, and anti-osteoarthritis potentials, and in eight in vivo studies, assessing their analgesic, antioxidant, antinociceptive, and anti-osteoarthritis activities. Some of the main related molecular mechanisms identified are the modulation of cytokines such as IL-1β, IL-6, and TNF-α, as well as the inhibition of inflammatory mediators and prostaglandin synthesis. The limited number of studies showed that commonly available species from the genus Miconia are safe for consumption. Miconia albicans Sw.Triana and Miconia rubiginosa (Bonpl.) DC was the most frequently used species and showed significant efficacy and potential for developing safe drugs to treat pain and inflammation.

Abstract
Propolis, a natural product made by bees with resins and balsams, is known for its complex chemical composition and remarkable bioactivities. In this study, propolis extraction was studied seeking extracts with strong bioactivities using less orthodox solvents, with some derived from apiary products. For that, a propolis sample collected from Gerês apiary in 2018 (G18) was extracted by maceration with six different solvents: absolute ethanol, ethanol/water (7:3), honey brandy, mead, propylene glycol and water. The solvent influence on the chemical composition and antioxidant and antimicrobial activities of the extracts was investigated. Antioxidant potential was assessed by the DPPH free-radical-scavenging assay and the antimicrobial activity by the agar dilution method. Chemical composition of the extracts was determined in vitro by three colorimetric assays: total ortho-diphenols, phenolics and flavonoids contents and the LC-MS technique. To our knowledge, this is the first time that solvents such as honey brandy and mead have been studied. Honey brandy showed considerable potential to extract propolis active compounds able to inhibit the growth of bacteria such as the methicillin-sensitive Staphylococcus aureus and Propionibacterium acnes (MIC values of 100 and 200 µg/mL, respectively) and the fungi Candida albicans and Saccharomyces cerevisiae (MIC = 500 µg/mL, for both). Mead extracts displayed high antioxidant capacity (EC50 = 1.63 ± 0.27 µg/mL) and great activity against resistant bacteria such as the methicillin-resistant Staphylococcus aureus and Escherichia coli (MIC = 750 µg/mL, for both). The production of such solvents made from beehive products further promotes a diversification of apiary products and the exploration of new applications using eco-friendly solutions.

Abstract
Papaver decaisnei (P. decaisnei) has been used as folkloric medicine for many health issues including gastric problems. The current study investigates the gastroprotective roles of P. decaisnei against ethanol-induced ulcers in rodents. Sprague Dawley rats (30) were separated into five groups: the normal group (G1) and the ulcer control group (G2) were orally administered 0.5% carboxymethylcellulose (CMC); the reference group (G3) was administered 20 mg/kg of Omeprazole; two experimental groups were fed with 200 mg/kg (G4) and 400 mg/kg (G5) of the P. decaisnei extract (PDE), respectively. Next, the rats were given absolute ethanol and sacrificed for the analysis of the gastric mucosal injury through microscopic, enzymatic, histologic, and immunohistochemistry assays. The ulcer controls showed significant superficial hemorrhagic gastric mucosal lesions, with a decreased gastric wall mucus and edema production, whereas fewer were found for the reference and plant-treated rats. Furthermore, the PDE pre-treated rats had a significantly reduced the periodic acid-Schiff (PAS) staining intensity, produced the upregulation of the HSP70 protein, and the downregulation of the Bax protein expressions in the stomach epithelium. P. decaisnei displayed a significant role in the upregulation of endogenous antioxidant enzymes (SOD, CAT, and PGE2), significantly reduced malondialdehyde (MDA), TNF-a, IL-6, and upraised the IL-10 levels. Based on the positive impacts, the PDE can be proposed as the protective/treatment agent against gastric ulcers and stomach lesions.

Phytochemical Evaluation and Anti-Inflammatory Potential of Miconia albicans (Sw.) Triana Extracts. Molecules 2022; 27:molecules27185954. [PMID: 36144693 PMCID: PMC9500825 DOI: 10.3390/molecules27185954] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Revised: 09/02/2022] [Accepted: 09/07/2022] [Indexed: 11/17/2022] Open
Abstract
The plant Miconia albicans (Sw.) Triana has been popularly used in Brazil to treat chronic inflammatory disturbances, such as osteoarthritis. This disease affects 250 million people worldwide, and is associated with intense pain and loss of articular function. There is a lack of information about the phytochemistry and bioactivity of M. albicans. Therefore, this study determined the chemical composition of some extracts and evaluated their cytotoxicity, along with their antioxidant and anti-inflammatory, activities using in vitro models. Aqueous and ethanolic extracts were prepared. Afterwards, a liquid–liquid partition was developed using chloroform, ethyl acetate, and n-butanol. The extracts were characterized by LC–MS, and their biological activities were evaluated on epithelial cells (Vero), tumoral hepatic cells (Hep-G2), and THP-1 macrophages. LC–MS analyses identified several flavonoids in all fractions, such as quercetin, myricetin, and their glycosides. The crude extracts and n-butanol fractions did not present cytotoxicity to the cells. The non-toxic fractions presented significant antioxidant activity when evaluated in terms of DPPH scavenging activity, lipid peroxidation, and ROS inhibition. THP-1 macrophages treated with the n-butanol fraction (250 µg/mL) released fewer pro-inflammatory cytokines, even in the presence of LPS. In the future, it will be necessary to identify the phytochemicals that are responsible for anti-inflammatory effects for the discovery of new drugs. In vivo studies on M. albicans extracts are still required to confirm their possible mechanisms of action.

Abstract
ETHNOBOTANICAL RELEVANCE With most of the anti-rheumatic drugs having severe adverse drug reactions and poor tolerance, the active components from natural herbs provides a repository for novel, safe, and effective drug development. Sanguisorba officinalis L. exhibits definite anti-inflammatory capacity, however, whether it has anti-rheumatic effects has not been revealed. AIM OF THE STUDY In the present study, the effect of Ziyuglycoside I (Ziyu I), one of the most important active components in Sanguisorba officinalis L., was investigated in treating collagen-induced arthritis (CIA), illuminating its potential pharmacological mechanisms. MATERIAL AND METHODS CIA mice were treated with 5, 10, or 20 mg/kg of Ziyu I or 2 mg/kg of MTX, and clinical manifestations as well as pathological changes were observed. T and B cell viability was determined using cell counting kit-8, plasma autoantibodies and cytokines were tested with ELISA, T and B cell subsets were identified by flow cytometry, Blimp1 expression was detected by RT-qPCR and in situ immunofluorescence. The expression of activation-induced cytidine deaminase (AID) was detected by immunohistochemistry. ERK activation in B cells was verified through western blotting and immunofluorescence. Meanwhile, bioinformatics retrieval and molecular docking/molecular dynamics were used to predict the relationship between Blimp1, ERK and Ziyu I with the pharmacokinetics and toxicity of Ziyu I being evaluated in the ADMETlab Web platform. RESULTS Ziyu I treatment effectively alleviated the joint inflammatory manifestation including arthritis index, global scores, swollen joint count and body weight of CIA mice. It improved the pathological changes of joint and spleen of arthritic mice, especially in germinal center formation. Ziyu I displayed a moderate regulatory effect on T cell activation, the percentage of total T and helper T cells, and tumor necrosis factor-α, but transforming growth factor-β was not restored. Increased spleen index, B cell viability and plasma auto-antibody production in CIA mice were significantly reduced by Ziyu I therapy. Of note, we found that Ziyu I administration substantially inhibited the excessive expansion of plasma cells in spleen through preventing the expression of B lymphocyte induced maturation protein 1 (Blimp1) and AID in B cells. Ziyu I was predicted in silico to directly interact with ERK2, and reduce ERK2 activation, contributing to the depressed expression of Blimp1. Moreover, Ziyu I was predicted to have a favorable pharmacokinetic profile and low toxicity. CONCLUSION Ziyu I effectively ameliorates CIA in mice by inhibiting plasma cell generation through prevention of ERK2-mediated Blimp1 expression in B cells. Therefore, Ziyu I is a promising candidate for anti-arthritic drug development.

Abstract
Inflammatory arthritis is the most prevalent chronic inflammatory disease worldwide. The pathology of the disease is characterized by increased inflammation and oxidative stress, which leads to chronic pain and functional loss in the joints. Conventional anti-arthritic drugs used to relieve pain and other arthritic symptoms often cause severe side effects. α-bisabolol (BIS) is a sesquiterpene that exhibits high anti-inflammatory potential and a significant antinociceptive effect. This study evaluates the anti-arthritic, anti-inflammatory and antihyperalgesic effects of BIS alone and in a β-cyclodextrin (βCD/BIS) inclusion complex in a CFA-induced arthritis model. Following the intra-articular administration of CFA, male mice were treated with vehicle, BIS and βCD/BIS (50 mg/kg, p.o.) or a positive control and pain-related behaviors, knee edema and inflammatory and oxidative parameters were evaluated on days 4, 11, 18 and/or 25. Ours findings shows that the oral administration of BIS and βCD/BIS significantly attenuated spontaneous pain-like behaviors, mechanical hyperalgesia, grip strength deficit and knee edema induced by repeated injections of CFA, reducing the joint pain and functional disability associated with arthritis. BIS and βCD/BIS also inhibited the generation of inflammatory and oxidative markers in the knee and blocked MAPK in the spinal cord. In addition, ours results also showed that the incorporation of BIS in cyclodextrin as a drug delivery system improved the pharmacological profile of this substance. Therefore, these results contribute to the pharmacological knowledge of BIS and demonstrated that this terpene appears to be able to mitigate deleterious symptoms of arthritis.

JFNE-A isolated from Jing-Fang n-butanol extract attenuates lipopolysaccharide-induced acute lung injury by inhibiting oxidative stress and the NF-κB signaling pathway via promotion of autophagy. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2022; 96:153891. [PMID: 35026506 DOI: 10.1016/j.phymed.2021.153891] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/16/2021] [Revised: 11/28/2021] [Accepted: 12/11/2021] [Indexed: 06/14/2023]
Abstract
BACKGROUND Jing-Fang powder consists of Jingjie (Nepeta tenuifolia Benth, (Lamiaceae)). and Fangfeng (Saposhnikovia divaricata (Turcz.) Schischk, (Apiaceae)) Previous studies have revealed that the Jing-Fang powder n-butanol extract (JFNE) has anti-acute lung injury (ALI) and anti-inflammatory properties; however, the active ingredient and mechanism remain unknown. PURPOSE In the present study, we investigated the anti-inflammatory effect of a bioactive fraction obtained from JFNE(JFNE-A) on lipopolysaccharide (LPS)-induced ALI in mice and explored the underlying mechanism. STUDY DESIGN The anti-acute lung injury effect and mechanism of JFNE-A was investigated by prophylactic administration of JFNE-A in mice with LPS-induced acute lung injury. METHODS The expression levels of myeloperoxidase(MPO) in lung tissues of mice and interleukin(IL)-6, tumor necrosis factor(TNF)-α, IL-1β, IL-5, interferon (IFN)-γ, monocyte chemotactic protein (MCP)-1, macrophage colony stimulating factor (M-CSF), macrophage inflammatory protein (MIP)-1α, and MIP-1β in bronchi alveolar lavage fluid (BALF) were detected by reagent kit and the histological changes were examined by hematoxylin and eosin (H & E) for general histopathological conditions under a light microscope. In addition, the ultrastructure of the cells in lung tissues were observed and photographed under a transmission electron microscope. The expression levels of protein were detected via Western blotting and the mRNA expression of relative genes were determined of via reverse transcriptase polymerase chain reaction (RT-PCR). What's more, we also further clarified the potential targets of JFNE-A through network pharmacology analysis, which could be utilized in ALI treatment. RESULTS Our results showed that pretreatment with JFNE-A for 7 days significantly reduced the lung pathological injury score, alleviated pulmonary edema, and decreased the lung tissue MPO level. Mechanistically, JFNE-A dramatically downregulated the protein levels of IL-6, TNF-α, IL-1β, M-CSF, and IFN-γ in BALF and mRNA expression levels of IL-6, TNF-α, IL-1β, and IFN-γ in lung tissues. JFNE-A also significantly lowered the protein levels of iNOS and phosphorylated NF-κB (p65) and mRNA expression levels of iNOS, Rela, CHUK, and NF-κB1, and also elevated the protein expression levels of Nrf2, HO-1, and SOD1 and the mRNA expression levels of Nrf2, Hmox1, and Keap-1 in the lungs. Moreover, JFNE-A significantly decreased the protein expression of p62 and increased the ratio of LC3II/LC3I. It also upregulated the mRNA expression levels of Atg5 and Beclin-1, whereas it reduced the mRNA expression level of SQSTM1 and increased autophagosome structures. CONCLUSION Overall, treatment with JFNE-A ameliorated LPS-induced ALI in mice by suppressing the NF-κB signaling pathways and promoting Nrf2 signaling pathways by accelerating autophagy.

Chemical profile, antioxidant and anti-inflammatory properties of Miconia albicans (Sw.) Triana (Melastomataceae) fruits extract. JOURNAL OF ETHNOPHARMACOLOGY 2021; 273:113979. [PMID: 33647428 DOI: 10.1016/j.jep.2021.113979] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/14/2020] [Revised: 02/10/2021] [Accepted: 02/22/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Miconia albicans (Sw.) Triana has been widely used in Brazilian popular medicine for the treatment of several diseases. Aerial parts are used as an infusion to treat arthrosis and arthritis, to relieve rheumatic and stomach pains, and intestinal disorders due to its anti-inflammatory, anti-mutagenic anti-nociceptive, digestive and hepatoprotective properties. AIM OF THE STUDY This study aimed to characterize the of M. albicans (Sw.) Triana fruits extract (MAFRE) chemical profile and to evaluate its antioxidant, anti-inflammatory and antitumor activities, as well as its toxicity. MATERIALS AND METHODS Maceration with methanol as liquid extractor was used to prepare MAFRE. M. albicans (Sw.) Triana fruits chemical composition was characterized by UHPLC-QTOF-MS/MS and GC-FID (fatty acid methyl esters composition from lyophilized fruits). MAFRE antioxidant potential was evaluated in vitro using a combination of assays: Folin-Ciocalteu reducing capacity, DPPH• and ABTS radical scavenging ability and ferric reducing antioxidant power (FRAP). In vitro antiproliferative activity was investigated in four human tumor cell lines (U251, 786-0, HT29 and MDA-MB-231) while the effect on the non-tumor cell viability was assessed in the VERO cell line using the on-step MTT assay. In addition, in vivo anti-inflammatory effect was assessed by Croton oil-induced ear edema in mice followed by myeloperoxidase (MPO) activity evaluation. RESULTS Thirty-five compounds were identified by UHPLC-QTOF-MS/MS. Among it flavonoids derived from quercetin (8), myricetin (1), kaempferol (2), terpenoids (6) and other compounds (18). GC-FID analysis identified and quantified nine fatty acids: palmitic, stearic, arachidic, behenic, elaidic, oleic, eicosenoic, and linoleic acids. The most abundant fatty acids were polyunsaturated fatty acids (5.33 ± 0.17 mg g-1), followed by saturated fatty acids (2.38 ± 0.07 mg g-1) and monounsaturated fatty acids (1.74 ± 0.09 mg g-1). The extract revealed high content of phenolic compounds (43.68 ± 0.50 mg GAE/g of extract), potent antioxidant, and ferrous chelating capacities. Morever, it proved to be non-toxic to the VERO cells, not affecting cells viability (95% of viable cells). No antiproliferative effect against human tumor cell lines were found. Furthermore, MAFRE significantly (p<0.05) reduced ear edema (≈35%) and MPO activity (84.5%) having a statistical effect similar to traditional steroidal and non-steroidal anti-inflammatory drugs. CONCLUSIONS Taken together, the results evidenced that M. albicans fruit extract has antioxidant properties, a higher concentration of phenolic compounds, flavonoids, fatty acids, and also topical anti-inflammatory activity with low toxicity of extract on VERO cells. Through the ethnomedicinal study, these findings supporting the popular use of M. albicans, but also highlight that not only aerial parts and leaves deserve attention, but the fruits also have anti-inflammatory proprieties and can be a source of phenolic compounds and other substances with potential health benefices.
