EFFECT OF PULSED ELECTRIC FIELD (PEF) AND CRYOCONCENTRATION (c) IN AQUEOUS EXTRACTS OF MAQUI (Aristotelia chilensis (Mol.) Stuntz) AND CALAFATE (Berberis microphylla G.) ON PHYSICOCHEMICAL PROPERTIES, MICROBIOLOGICAL QUALITY, AND BIOACTIVE COMPOUNDS

The objective of this study was to evaluate the effect of PEF treatment followed by cryoconcentration (c) in aqueous extracts of maqui (Aristotelia chilensis (Mol.) Stuntz) and calafate (Berberis microphylla G.) on their physicochemical properties, microbiological quality, and bioactive compounds. Extracts of maqui and calafate were obtained by aqueous extraction of water-soluble compounds, and then samples were treated by PEF (10kV/cm, 70Hz and a pulse width of 10 µs) and pasteurization (90°C/30s); untreated samples were used as controls. The treated extracts were cryoconcentrated using centrifugation-filtration, and the cryoconcentration parameters included separation efficiency (EFF) and recovered solute (RS). Physicochemical properties were also evaluated, such as soluble solids (SS), titratable acidity (TTA), and viscosity (ƞ), as well as bioactive compound content: total polyphenols (TP), total anthocyanins (TA), total flavonoids (TF) and antioxidant capacity (AOXC). Microbiological quality was evaluated by the counts of the mesophilic aerobic microorganism (MAM) and molds and yeasts (M&Y). The results showed that the EFF of the solutes was higher than 95% in maqui and 97% in calafate. As expected, the cryoconcentration process increased TA, ƞ, and SS content. It also significantly increased (p<0.05) in TP, TF, TA, and AOXC content.The microbiological results showed that PEF treatment, together with cryoconcentration and refrigerated storage, maintained the microbiological quality of maqui cryoconcentrates for more than 50 days, whereas in calafate cryoconcentrates, it was maintained for ~20 days. Moreover, the physicochemical parameters and bioactive compounds of both cryoconcentrates remained stable during the refrigerated storage period.These results demonstrate that the combined use of PEF with cryconcentration seems to be a good option for microbiological and physiochemical stabilization of fruit juices with a high AOXC and for increasing the content of bioactive compounds.

Early Growth and Physiological Acclimation to Shade and Water Restriction of Seven Sclerophyllous Species of the Mediterranean Forests of Central Chile.

The success of using active restoration in Mediterranean-type climate zones mostly depends on an appropriate matching of plant species and specific management prescriptions upon establishment. In this study, we assessed the early growth and short-term physiological acclimation of seven common species found in the sclerophyllous forests in central Chile to water restriction and shading. We established a nursery experiment that included three treatments (T0: sun-exposed and water-restricted, T1: sun-exposed and fully irrigated, and T2: shaded and fully irrigated) and seven tree species differing in their shade and drought tolerance (Quillaja saponaria Molina, Aristotelia chilensis (Mol.) Stuntz, Peumus boldus Molina, Lithraea caustica (Mol.) Hook. and Arn, Luma apiculata (DC.) Burret, Colliguaja odorifera Molina, and Escallonia pulverulenta (Ruiz and Prav.) Pers). We measured the increment in seedling height and different leaf morpho-physiological traits during two months in the dry season. Based on the measured traits, none of the species took advantage of the higher water availability in T1 relative to T0, but most of the species responded to the shade in T2, regardless of their shade or drought tolerance. Height increments due to shade varied from 0% in P. boldus to 203% in L. apiculata. Overall, all the species responded similarly to the treatments in specific leaf area, chlorophyll content index, photosynthetic rate, stomatal conductance, and intrinsic water use efficiency. This suggests that the species exhibited similar acclimation patterns of these parameters to shade and drought, even regarding the variation in midday xylem water potential found in the water-restricted treatment T0 (from -1.5 MPa in P. boldus to -3.1 MPa in E. pulverulenta). In this study, shading had a higher positive effect on the seedling performance of sclerophyllous species than watering, which at operational level highlights the need for investing in tree shelters when using these species in restoration programs.

Aqueous extract of pulp of maqui-berry (Aristotelia chilensis) induces apoptosis in human endometrial carcinoma ishikawa cells via mitochondrial and endoplasmic reticulum stress pathways

In Chilean traditional medicine, Aristotelia chilensis (Mol) Stuntz is commonly utilized for a variety of conditions (particularly digestive problems). We investigated the effects of an aqueous extract from the fruit pulp of A. chilensis (Maqui berry: M2) on endoplasmic reticulum stress and mitochondrial pathway-induced early apoptosis in Ishikawa cells. Using the MTT assay, the aqueous extract was found to have an inhibitory impact on human endometrial cancer Ishikawa cells, with an IC50 of 5.36 μg/mL. The changes in Ishikawa cells under the effect of M2 were detected by flow cytometry with cycle arrest in S phase, reduced mitochondrial membrane potential, ROS and calcium ion aggregation. Western blotting and RT-qPCR were used to identify the intracellular mRNA and protein alterations. The presence of M2 resulted in the up-regulation of mitochondrial pathway-related proteins Bad, Bax, and Cyto C, down-regulation of Bcl-2, and up-regulation of endoplasmic reticulum stress-related proteins IRE1α, p-eif2α, ATF4, and CHOP. The findings imply that A. chilensis pulp may be used as a possible raw material for the innovative functional applications.

Optimization of Oil and Tocopherol Extraction from Maqui (Aristotelia chilensis (Mol.) Stuntz) by Supercritical CO2 Procedure.

This study focused on the oil extraction from freeze-dried maqui (Aristotelia chilensis) by supercritical fluid extraction with carbon dioxide (SFE-CO2). The basic objective was to optimize the oil yield and the tocopherol concentration. A Box/Behnken experimental design was developed with three processing variables: supercritical pressure (74, 187, and 300 bar), temperature (35, 48, and 60 °C), and extracting time (30, 135, and 240 min). Multiple optimizations, based on the combination of factor levels at 274 bar, 240 min, and 60 °C, led to the highest oil yield and tocopherol values. The validation of the optimized conditions of maqui oil extraction led to an oil yield of 8% and values of 735, 53, and 97 (mg·kg-1 oil) for α-tocopherol, α-tocotrienol, and γ-tocopherol, respectively. A higher concentration of tocopherol compounds was observed when compared to the employment of the conventional extracting method. The optimized SFE-CO2 method led to an oil extract exhibiting higher Hydrophilic-Oxygen Radical Absorbance Capacity (H-ORAC) assay and total phenol content (22 μmol Trolox equivalents·g-1 oil and 28 mg gallic acid equivalents·g-1 oil) than the oil obtained by the conventional procedure. A practical and accurate oil extraction is proposed for obtaining tocopherol-enriched oil including high concentrations of valuable lipophilic antioxidants.

A Review of the Functional Characteristics and Applications of Aristotelia chilensis (Maqui Berry), in the Food Industry.

The Aristotelia chilensis (Mol.) Stuntz, also known as Maqui, is an endemic berry native to southern Chile. It is a very popular berry for its nutritional attributes and health benefits, provided mainly by its polyphenols. This review aims to investigate the Maqui and its nutritional characteristics, its health benefits, and the application of Maqui in the food industry. This fruit provides 150 calories per 100 g of product and has a low protein content and a high fiber content. Its seeds contain monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs); however, its most outstanding feature is its high value of bioactive compounds, mainly anthocyanins, indole alkaloids and flavonoids, coumarins, caffeic and ferulic acids, and delphinidin 3-O-β-glucoside, the latter being the most representative, providing Maqui with high antioxidant activity. Maqui is considered a fruit of high interest as a nutraceutical product for the control and prevention of ongoing diseases, and among its benefits, we can highlight glycemic and metabolic control; the control and prevention of obesity, cancer, cognitive decline, and dementia; the prevention and treatment of bone structure alterations; prevention against oxidative stress, particularly in cigarette smoke-induced stress. In addition to its nutraceutical use, Maqui has been used in the food industry to improve the shelf life (by controlling lipid oxidation) and nutritional value of food products and as a substitute for synthetic additives. In addition, the inclusion of Maqui improves the organoleptic and sensory characteristics of foods. The incorporation of this fruit has been observed mainly in drinks, meat products, bakery products, and milk products. Evidence has shown that Maqui consumption, as well as products with Maqui added, have a good acceptability and exert benefits on people's health. Knowledge about the application of Maqui in food will allow us to create new nutraceutical and food products that improve their nutritional and functional value.

Nanoencapsulation of Maqui (Aristotelia chilensis) Extract in Chitosan-Tripolyphosphate and Chenopodin-Based Systems.

Maqui berries contain a high percentage of anthocyanins with high antioxidant and anti-inflammatory capacity but that are unstable in the colonic site. Nanocarriers based on polysaccharides and/or proteins can protect against the degradation of anthocyanins. The aim of this study was the nanoencapsulation of maqui extract (ME) in chitosan-tripolyphosphate (CTPP-ME), chenopodin (CH-ME), and chenopodin-alginate (CHA-ME). A standardised ME was prepared and then encapsulated in the nanosystems. The physicochemical properties, encapsulation parameters, and the interactions of ME with the nanovehicles were characterised. The cyanidin-3-glucoside released and ORAC activity in phosphate buffer at pH 7.4 were evaluated. The content of ME was 8-9 mg of cyanidin-3-glucoside/g of extract. CTPP with ME at 3% obtained the highest encapsulation efficiency (EE = 91%), and no significant differences were observed in size (274-362 nm), PDI (0.5-0.7), and zeta potential (+34-+41 mV) when the concentration of ME changed from 1% to 5%. CH-ME was shown to be smaller (152 nm) than CTPP-ME, and CH-ME and CHA-ME showed lower EE (79% and 54%, respectively) than CTPP-ME. FT-IR revealed a stronger interaction of ME with CTPP-ME than with CH-ME. Both systems showed a significantly lower release than free ME, and the T50 value of CTPP-ME 3% (328 min) was higher than CH-ME (197 min). Both protected the ORAC activity of ME.

Delphinidins from Maqui Berry (Aristotelia chilensis) ameliorate the subcellular organelle damage induced by blue light exposure in murine photoreceptor-derived cells.

Blue light exposure is known to induce reactive oxygen species (ROS) production and increased endoplasmic reticulum stress, leading to apoptosis of photoreceptors. Maqui berry (Aristotelia chilensis) is a fruit enriched in anthocyanins, known for beneficial biological activities such as antioxidation. In this study, we investigated the effects of Maqui berry extract (MBE) and its constituents on the subcellular damage induced by blue light irradiation in mouse retina-derived 661W cells. We evaluated the effects of MBE and its main delphinidins, delphinidin 3-O-sambubioside-5-O-glucoside (D3S5G) and delphinidin 3,5-O-diglucoside (D3G5G), on blue light-induced damage on retinal cell line 661W cells. We investigated cell death, the production of ROS, and changes in organelle morphology using fluorescence microscopy. The signaling pathway linked to stress response was evaluated by immunoblotting in the whole cell lysates or nuclear fractions. We also examined the effects of MBE and delphinidins against rotenone-induced mitochondrial dysfunction. Blue light-induced cell death, increased intracellular ROS generation and mitochondrial fragmentation, decreased ATP-production coupled respiration, caused lysosomal membrane permeabilization, and increased ATF4 protein level. Treatment with MBE and its main constituents, delphinidin 3-O-sambubioside-5-O-glucoside and delphinidin 3,5-O-diglucoside, prevented these defects. Furthermore, MBE and delphinidins also protected 661W cells from rotenone-induced cell death. Maqui berry may be a useful protective agent for photoreceptors against the oxidative damage induced by exposure to blue light.

Physiologic effects of the maqui berry (Aristotelia chilensis): a focus on metabolic homeostasis.

The prevalence and socioeconomic impact of metabolic diseases is rapidly growing. The limited availability of effective and affordable treatments has fuelled interest in the therapeutic potential of natural compounds as they occur in selected food sources. These compounds might help to better manage the current problems of treatment availability, affordability, and adverse effects that, in combination, limit treatment duration and efficacy at present. Specifically, berries garnered interest given a strong epidemiological link between their consumption and improved metabolic functions, making the analysis of their phytochemical composition and the identification and characterization of biologically active ingredients an emerging area of research. In this regard, the present review focuses on the South American maqui berry Aristotelia chilensis, which has been extensively used by the indigenous Mapuche population for generations to treat a variety of disease conditions. An overview of the maqui plant composition precedes a review of pre-clinical and clinical studies that investigated the effects of maqui berries and their major components on metabolic homeostasis. The final part of the review highlights possible technologies to conserve maqui berry structural and functional integrity during passage through the small intestine, ultimately aiming to augment their systemic and luminal bioavailability and biological effects. The integration of the various aspects discussed herein can assist in the development of effective maqui-based therapies to benefit the growing population of metabolically compromised patients.

In Silico and In Vivo Evaluation of the Maqui Berry (Aristotelia chilensis (Mol.) Stuntz) on Biochemical Parameters and Oxidative Stress Markers in a Metabolic Syndrome Model.

Metabolic syndrome (MetS) is a complex disease that includes metabolic and physiological alterations in various organs such as the heart, pancreas, liver, and brain. Reports indicate that blackberry consumption, such as maqui berry, has a beneficial effect on chronic diseases such as cardiovascular disease, obesity, and diabetes. In the present study, in vivo and in silico studies have been performed to evaluate the molecular mechanisms implied to improve the metabolic parameters of MetS. Fourteen-day administration of maqui berry reduces weight gain, blood fasting glucose, total blood cholesterol, triacylglycerides, insulin resistance, and blood pressure impairment in the diet-induced MetS model in male and female rats. In addition, in the serum of male and female rats, the administration of maqui berry (MB) improved the concentration of MDA, the activity of SOD, and the formation of carbonyls in the group subjected to the diet-induced MetS model. In silico studies revealed that delphinidin and its glycosylated derivatives could be ligands of some metabolic targets such as α-glucosidase, PPAR-α, and PPAR-γ, which are related to MetS parameters. The experimental results obtained in the study suggest that even at low systemic concentrations, anthocyanin glycosides and aglycones could simultaneously act on different targets related to MetS. Therefore, these molecules could be used as coadjuvants in pharmacological interventions or as templates for designing new multitarget molecules to manage patients with MetS.

Antioxidant Properties of Maqui Berry Extract (Aristotelia chilensis (Mol.) Stuntz) and Its Potential Photoprotective Role on Human Skin Fibroblasts

Maqui berry (Aristotelia chilensis) is characterized by antioxidant and anti-inflammatory properties. The aim of this study was to evaluate the effect of maqui berry extracts on human skin fibroblasts (NHSFs) exposed to ultraviolet radiation (UVB). The photoprotective properties of the extracts were investigated via the determination of the total polyphenolic content (TPC) and antioxidant capacity (DPPH), and the chemical composition was assessed. The chemical purity of the extracts was studied via the evaluation of the toxic elements level. The water extract (MWE 57.75 ± 0.44 mg GAE/g) had the highest mean polyphenol content. The water (MWE) and ethanol (MEE70) extracts had the highest inhibitory activities against DPPH radical formation (283.63 ± 7.29 and 284.60 ± 4.31 mg Tx/L, respectively). The analyzed extracts were found to be safe in terms of toxic elements (arsenic, cadmium, lead). The tested extracts of maqui berry did not cause a cytotoxic effect on NHSF cells after 24, 48, and 72 h of incubation. When the NHSF cells were exposed to UVB radiation in the presence of maqui extracts, their viability was increased or maintained. The maqui berry extracts had a slightly protective effect against skin damage caused by UVB radiation. These were preliminary studies that require further research to determine which maqui compounds correspond with the photoprotective activity.

Natural Compounds Purified from the Leaves of Aristotelia chilensis: Makomakinol, a New Alkaloid and the Effect of Aristoteline and Hobartine on NaV Channels.

Aristotelia chilensis or "maqui" is a tree native to Chile used in the folk medicine of the Mapuche people as an anti-inflammatory agent for the treatment of digestive ailments, fever, and skin lesions. Maqui fruits are black berries which are considered a "superfruit" with notable potential health benefits, promoted to be an antioxidant, cardioprotective, and anti-inflammatory. Maqui leaves contain non-iridoid monoterpene indole alkaloids which have previously been shown to act on nicotinic acetylcholine receptors, potassium channels, and calcium channels. Here, we isolated a new alkaloid from maqui leaves, now called makomakinol, together with the known alkaloids aristoteline, hobartine, and 3-formylindole. Moreover, the polyphenols quercetine, ethyl caffeate, and the terpenes, dihydro-β-ionone and terpin hydrate, were also obtained. In light of the reported analgesic and anti-nociceptive properties of A. chilensis, in particular a crude mixture of alkaloids containing aristoteline and hobartinol (PMID 21585384), we therefore evaluated the activity of aristoteline and hobartine on NaV1.8, a key NaV isoform involved in nociception, using automated whole-cell patch-clamp electrophysiology. Aristoteline and hobartine both inhibited Nav1.8 with an IC50 of 68 ± 3 µM and 54 ± 1 µM, respectively. Hobartine caused a hyperpolarizing shift of the voltage-dependence of the activation, whereas aristoteline did not change the voltage-dependence of the activation or inactivation. The inhibitory activity of these alkaloids on NaV channels may contribute to the reported analgesic properties of Aristotelia chilensis used by the Mapuche people.

Kombucha analogs from maqui juice: Consortium age and sugar concentration effects on anthocyanin stability and its relationship with antioxidant activity and digestive enzyme inhibition.

The fermentation of maqui juice (MJ), by incorporating kombucha as a starter culture, produces beverages with variable and stable anthocyanin contents. The metabolic effect of kombucha starter cultures obtained at different fermentation times was explored on the anthocyanin stability of maqui (Aristotelia chilensis (Mol.) Stuntz) juice supplemented at different concentrations of sucrose and fermented at different times. The stability of anthocyanins was associated with the levels of catechin detected in the fermentation system. This study concludes that the fermentation of MJ with sucrose (10%) and kombucha consortium of 7-days old, promotes the release and accumulation of phenolic compounds that act as co-pigments, with the best response in quality parameters of beverages such as color intensity, tone, hyperchromic effect, and a significant bathochromic shift. Finally, the additive effect of phenolic constituents with stable anthocyanins, confers to kombucha analogs an outstanding antioxidant quality and inhibitory effects on key enzymes in digestive processes.

Herbal Extracts of Ginseng and Maqui Berry Show Only Minimal Effects on an In Vitro Model of Early Fracture Repair of Smokers.

Smoking is a major risk factor for delayed fracture healing, affecting several aspects of early fracture repair, including inflammation, osteogenesis, and angiogenesis. Panax ginseng (GE) and maqui berry extract (MBE) were shown in our previous studies to reduce smoke-induced cellular damage in late bone-healing in vitro models. We aimed here to analyze their effects on the early fracture repair of smokers in a 3D co-culture model of fracture hematomas and endothelial cells. Both extracts did not alter the cellular viability at concentrations of up to 100 µg/mL. In early fracture repair in vitro, they were unable to reduce smoking-induced inflammation and induce osteo- or chondrogenicity. Regarding angiogenesis, smoking-induced stress in HUVECs could not be counteracted by both extracts. Furthermore, smoking-impaired tube formation was not restored by GE but was harmed by MBE. However, GE promoted angiogenesis initiation under smoking conditions via the Angpt/Tie2 axis. To summarize, cigarette smoking strikingly affected early fracture healing processes in vitro, but herbal extracts at the applied doses had only a limited effect. Since both extracts were shown before to be very effective in later stages of fracture healing, our data suggest that their early use immediately after fracture does not appear to negatively impact later beneficial effects.

Maqui berry extract inhibits filamentation of Candidaalbicans and improves the antifungal efficacy of nystatin

Candidiasis caused by Candida albicans is one of the most common fungal infections in modern society. The limited arsenal of clinical drugs, their side effects and emerging resistance, largely contribute to the low efficacy of current antifungal therapies. The morphogenetic yeast-to-hyphae transition is the key virulence feature for the establishment of local and systemic C. albicans infections. We show that a delfinidin-rich fruit extract from Aristotelia chilensis ([Molina], Stuntz) (maqui berry) inhibits filamentation of C. albicans, in both laboratory and clinical strains. The extract acts synergistically with nystatin, with filament formation completely prevented by the combination of ¼×MIC of nystatin and 0.125 mg/ml of the extract. The combination treatment results in increased survival of C. albicans-infected zebrafish embryos compared to treatment with nystatin. Neither the extract nor its combination with nystatin was toxic at effective doses. These results warrant further investigation of maqui berry extract as adjuvant antifungal treatment.

Cookies Enriched with Maqui (Aristotelia chilensis (Mol.) Stuntz) Flour: Good Source of Dietary Fiber and Antioxidant Capacity

Byproducts derived from the agricultural industry and food processing, such as seeds and skin or husks, have become important due to environmental sustainability and their value-added potential. Maqui (Aristotelia chilensis (Mol.) Stuntz) is a native Chilean wild tree that has several beneficial properties due to its high content of anthocyanins, anthocyanidins, phenolic acids, tannins, and fiber. The present study involved flour derived from maqui byproducts (seeds and skin) to produce cookies with a higher content of nutrients, dietary fiber, and antioxidants. Maqui bagasse was converted into flour and mixed with wheat flour to prepare the cookies. The control consisted of wheat flour cookies with no added maqui flour. Results indicated that the cookies with the added maqui flour were preferred more than the control and had a higher percentage of fiber. Compared with the control, the amount of anthocyanins increased 3.5 times, and the amount of antioxidants, measured via the DPPH (2,2 ′ -diphenyl-1-picrylhydrazyl radical) assay, increased approximately 10 times. Our results show that the incorporation of maqui byproducts, in the form of maqui flour, into the cookie formulation is an effective way to add nutritional value to cookies by increasing dietary fiber, total polyphenols, and total anthocyanins.

Antioxidant Activity as an Indicator of the Efficiency of Plant Extract-Mediated Synthesis of Zinc Oxide Nanoparticles.

The green synthesis of zinc oxide nanoparticles (ZnO NPs) using a diverse range of plant species has been extensively reported. Despite the success achieved by biogenic synthesis, there are problems with the control and prediction of the properties of ZnO NPs, due to phytochemical diversity between plant species. In this sense, the main objective of our work was to investigate the effect of the antioxidant activity (AA) of plant extracts on the physicochemical characteristics of ZnO NPs (production yield, chemical composition, polydispersity index (PDI), surface charge (ζ-potential) and average particle size). In order to accomplish this objective, four plant extract with different antioxidant activities were used: Galega officinalis, Buddleja globosa, Eucalyptus globulus, and Aristotelia chilensis. Phytochemical screening, quantitative analysis of phenolic compounds and antioxidant activity determination of the different extracts were carried out. Chemical species such as catechin, malvidin, quercetin, caffeic acid, and ellagic acid were the dominant components, found in the extracts studied. The A. chilensis extract showed the highest value of total phenolic compounds (TPC) and AA, followed by E. globulus, B. globosa and G. officinalis. Zetasizer, Fourier-transform infrared (FTIR), X-ray diffraction (XRD), transmission electron microscopy (TEM) and thermogravimetric analysis (TGA) data show that plant extracts with lower AA leads to a decrease in the yield of ZnO NPs and an increase in the amount of residual organic extract that remains on the particles. The latter caused an increase in the average particle size, PDI and ζ-potential as a consequence of agglomeration and particle coarsening. Our result suggest that it is possible to use the AA as an indicator of the potential reducing capacity of plant extracts. In this way it is possible to guarantee the reproducibility of the synthesis process as well as ensure the formation of ZnO NPs with desired characteristics.

Anti-Inflammatory Chilean Endemic Plants

Medicinal plants have been used since prehistoric times and continue to treat several diseases as a fundamental part of the healing process. Inflammation is a condition characterized by redness, pain, and swelling. This process is a hard response by living tissue to any injury. Furthermore, inflammation is produced by various diseases such as rheumatic and immune-mediated conditions, cancer, cardiovascular diseases, obesity, and diabetes. Hence, anti-inflammatory-based treatments could emerge as a novel and exciting approach to treating these diseases. Medicinal plants and their secondary metabolites are known for their anti-inflammatory properties, and this review introduces various native Chilean plants whose anti-inflammatory effects have been evaluated in experimental studies. Fragaria chiloensis, Ugni molinae, Buddleja globosa, Aristotelia chilensis, Berberis microphylla, and Quillaja saponaria are some native species analyzed in this review. Since inflammation treatment is not a one-dimensional solution, this review seeks a multidimensional therapeutic approach to inflammation with plant extracts based on scientific and ancestral knowledge.
