Chemical constituents from noni (Morinda citrifolia L.) fruit juice and their chemotaxonomic significance

Extensive phytochemical investigation on the noni juice, a globally renowned health beverage derived from the fermentation of noni (Morinda citrifolia L.) fruit in tropical regions, led to the discovery of a new coumarin glycoside, esculetin-7-O-β-d-glycopyranosyl-(1 → 6)-β-d-glucopyranoside (1), along with a new natural product (8), and eighteen known compounds: six coumarin derivatives (2–7), two alkaloids (9 and 16), six diketopiperazines (10–15), a furan derivative (17), and three lignans (18–20). The structures of these compounds were elucidated through extensive NMR and HRESIMS analysis. The NMR data of compounds 2 and 8 are reported comprehensively for the first time. The chemotaxonomic significance of the isolated compounds was also examined, highlighting their significance. Notably, compounds 1–4, 8–16, and 18 were being reported from the genus Morinda for the first time. These findings contribute to the growing understanding of the chemical diversity of noni juice.

Divine noni's protective impact on Swiss albino mice's short-term memory impairment caused by cyclophosphamide: A behavioral and biochemical approach

Cyclophosphamide (CYL) is a first-line cancer chemotherapeutic agent widely used for the treatment of cancer that has severe toxic effects. The primary mechanism by which CYL induces toxicity through free radical generation. Morinda citrifolia (Noni) fruit juice is an herbal remedy documented to have antioxidant properties. The aim of the current study was to investigate the protective effect of noni against CYL-induced memory impairment in Swiss albino mice. Treatment schedule: Group 1: Normal: Received vehicle; Group 2: CYL treatment: Received CYL (40.0 mg/kg b.w. i.p.) on day one; Group 3: NJ treatment: Received NJ (360 mg/b.w. p.o.) once daily for 14 days. Group 4: DNG treatment: DNG (360 mg/b.w. p.o.) once daily for 14 days, Group 5: NJ + CYL treatment: Received CYL (40.0 mg/kg b.w. i.p.) on day one and after half an hour of received NJ (360 mg/b.w. p.o.) once daily for 14 days. Group 6: DNG + CYL treatment: Received CYL (40.0 mg/kg b.w. i.p.) on day one and after half an hour received DNG (360 mg/b.w. p.o.) once daily for 14 days. Mice were subjected to the Morris water maze (MWM) challenge for two weeks as part of a behavioral study. Short-term memory impairment was observed in the behavioral activity of CYL-treated mice in the MWM test in the 1st week trial, and this effect was reversed in the 2nd week trial in the combination treatment group. The behavioral analysis proved that noni supplementation reduced the risk of memory impairment caused by CYL. Biochemical analysis revealed that CYL markedly increased the levels of AChE and MDA in brain tissue. Similarly, decreases in the levels of antioxidants, i.e., GSH, CAT, SOD and GST, were detected in the brain tissue of the mice exposed to CYL. Qualitative and quantitative examinations of histopathological examination of the mouse hippocampus supported the above findings. The results demonstrated that noni supplement therapy reversed the changes in the MDA, AChE, and antioxidant enzyme levels while improving the behavioral and histological alterations caused by CYL. Long-term hippocampal growth and memory are unaffected, suggesting that CYL is less harmful. According to our research, supplementing with noni in conjunction with CYL may be a helpful treatment strategy for treating memory impairment caused by CYL.

Antioxidant Activity and Consumer Acceptance Level of Kombucha Tea With Noni Fruit Extract (Morinda citrifolia)

This study aimed to investigate the impact of fermentation time and the best formulation of black tea and noni fruit juice on the production kombucha with the highest hedonic value and antioxidant activity. The research method involved (1) preparing kombucha tea, (2) assessing antioxidant activity, Total Solids value, pH value of the sample, and (3) conducting statical analysis using One-Way ANOVA followed by Tukey’s Post Hoc Test at a confidence level a = 5% and T test. The addition of noni juice was found to increase the antioxidant activity in kombucha; however, it reduced the overall hedonic value of kombucha. In conclusion, this study determined that sample P2 (200 mL of noni juice in 800 mL of black tea) was the best formulation. Statistical tests revealed that both fermentation time and formulation P2 significantly influenced the increase in antioxidant activity, reaching 41.20%. Additionally, the highest hedonic score was achived by the control sample fermented for 7 days, which scored to 6.68%.

Proximate composition, bioactive constituents, and therapeutic potentials of pasteurized Noni juice derived from <em>Morinda citrifolia</em> (L.) growing in Sri Lanka

Morinda citrifolia (L.), also known as Noni or Ahu in Sri Lanka, is infrequently consumed as a dietary supplement within the country due to its association with myths and perceived toxicity. Nonetheless, in Sri Lanka, limited scientific research has been undertaken in the past to explore the therapeutic potential of noni, with public awareness primarily focused on its exportdriven cultivation. The study focused on evaluating the proximate composition, bioactive constituents, and therapeutic potential of hydro-methanolic extracts from pasteurized noni fruit juice, employing an 80% methanol extraction method, filtration, and assessment through standard assays to elucidate its potentia health benefits. The juice showed noteworthy antioxidant potential through DPPH scavenging activity (57.90 ± 0.40 μg/mL) and ABTS scavenging activity (42.95 ± 1.33 μg/mL), as well as high nitric oxide inhibition activity (164.56 ± 3.22 μg/mL), suggesting its anti-inflammatory properties. The juice also displayed potential as an anti-diabetic agent by inhibiting alpha-amylase (27.68 ± 0.36 μg/mL) and alpha-glucosidase (25.67 ± 1.03 μg/mL). Furthermore, it exhibited potential in protecting against certain pathological processes through heat-induced hemolysis inhibition (36.08 ± 1.08 μg/mL), protein denaturation inhibition (56.14 ± 1.11 μg/mL), and proteinase inhibitory activity (38.04 ± 0.56 μg/mL). These findings support the potential use of pasteurized fruit juice as a functional food ingredient, offering benefits to both the food industry and consumers. Further research can be directed towards the development of Noni fruit-incorporated food products that possess desirable sensory attributes to mitigate any potential aversion associated with its taste and odor profiles.

The Potential of Noni (Morinda citrifolia L.) as an Anti-Diabetic

Background: Diabetes Mellitus (DM) is still a major health problem in the world today because the prevalence remains increasing. Type 2 diabetes is the most common type of diabetes, accounting for over 90% of all diabetes cases. This disease is characterized by insulin resistance, where the body cannot fully respond to insulin. As a result, glucose levels in the blood continue to increase (hyperglycemia). The main of Type 2 DM management is a healthy lifestyle. In addition, pharmacological therapy is also needed to keep blood glucose levels in diabetics under control. However, antidiabetic medicines can cause some side effects. Therefore, the development of alternative diabetes therapy has been done to minimize side effects. One of the herbal ingredients that are being studied for its potential as an anti-diabetic is noni (Morinda citrifolia L.).Objective: The aim of the study is to review and find out more about the potential of noni (Morinda citrifolia L.) as an anti-diabetic.Methods: This research is included in the type of literature review. The kinds of literature are English and Indonesian language research articles related to the topic searched by using database sources from ProQuest, PubMed, ScienceDirect, and Google Scholar. The research articles were published in the last 10 years (2012 to 2022). Results: There are 14 kinds of literature that match the topic of study. A total of 12 kinds of literature are in vivo studies on animals and 2 literature studies on humans. The result shows that noni has an antidiabetic effect by lowering blood glucose levels and improving other parameters. Parts of Noni that have the potential to control Type 2 DM are fruit and leaves, which can be in the form of extracts, juices, or fermented products. Further research is needed to evaluate the toxicity, the content of active compounds, and the expression of genes related to Type 2 DM for ensuring the mechanism of noni in controlling hyperglycemia. Human studies with more respondents are also needed to confirm the findings of existing studies. Conclusion: Noni has an antidiabetic effect by lowering blood glucose levels and improving other parameters. Based on human studies, noni fruit juice can serve as a suitable addition to the diet of Type 2 DM patients.

Noni (Morinda citrifolia L.) fruit juice reduces paw edema and protects gastric mucosal injury in rats

Edema is a reliable parameter to evaluate the anti-inflammatory process. Noni (Morinda citrifolia L.) fruit has been shown to decrease inflammation. However, studies on the impact of noni juice on gastric mucosal injury are still limited. Thus, the current study aimed to assess the effect of noni fruit juice as an anti-inflammatory agent in rat paw edema and gastric mucosal injury. The rats were divided into five groups such as control, carrageenan only, carrageenan and diclofenac sodium, carrageenan and 90% noni, and carrageenan + 100% noni. Paw edema was measured, and histopathological examination of the gastric tissues was performed. The administration of noni juice significantly reduced paw edema in the carrageenan + 90% noni and carrageenan + 100% noni groups of rats. Compared to the carrageenan + diclofenac sodium group, the carrageenan + 90% noni and carrageenan + 100% noni groups were not significantly different in reducing paw edema. It suggests that the administration of noni juice can reduce paw edema with the same potential as diclofenac sodium. Gastric mucosal injury in the carrageenan + diclofenac sodium group (scores 2 to 3) was higher than in the carrageenan + 90% noni and carrageenan + 100% noni groups (scores 1 to 2), both of them had significant differences (p<0.05). In conclusion, noni juice can reduce paw edema and protect against gastric mucosal injury.

A novel strategy for improving the antioxidant, iridoid, and flavor properties of Noni (Morinda citrifolia L.) fruit juice by lactic acid bacteria fermentation

Noni (Morinda citrifolia L.) fruit juice (NFJ) has an unpleasant flavor but is highly bioactive, so it is necessary to improve the quality of NFJ by exploring a novel strategy. The effects of eight lactic acid bacteria (LAB) on the antioxidant, phenolic, iridoid, and flavor properties of NFJ were investigated in the present study. The results showed that antioxidant activity was improved after NFJ fermentation by LAB and that L. rhamnosus had the highest free radical scavenging activity. The highest total phenolic content and total flavonoid content were in L. brevis-fermented NFJ (78.85 mg gallic acid equivalent/100 mL and 37.12 mg rutin equivalent/100 mL, respectively). Bioconversion of iridoid revealed that deacetylasperulosidic acid can be deacetylated from asperulosidic acid. Furthermore, LAB fermentation presented a significant decrease in unpleasant butanoic acid, with the lowest content found in L. fermentum-fermented NFJ. This research provides progressive information on the application of LAB culture in NFJ fermentation.

Growth and blood lipid profile of native chickens given noni juice (Morinda citifolia) via drinking water

The concept of phytogenic feed additives refers to natural medicinal products derived from herbal plants to promote the growth and health of poultry. This study aims to examine the inclusion of Noni fruit juice (NFJ) in drinking water on the growth and blood lipid profile of native chickens. A total of 160 native chickens aged 2 weeks with homogeneous body weight were randomly divided into 4 treatment groups and 4 replications, each repetition with 40 chickens. Chickens were given treatment, namely: chickens were given drinking water without NFJ (A), drinking water with 4% NFJ (B), drinking water with 4.5% NFJ (C), and drinking water with 5% NFJ (D). The results showed that NLJ supplementation in drinking water had no significant effect (P>0.05) on chicken growth and feed efficiency. Blood cholesterol and HDL levels showed significant differences (P<0.05) between treatments. The lowest blood cholesterol levels were found in group C chickens and the highest in group A chickens. On the other hand, the highest HDL levels were found in group C chickens and the lowest in group A chickens. It was concluded that supplementation of 4.5% NFJ in drinking water had no impact on growth, but significantly reduced cholesterol content and increased HDL concentrations in native chicken blood.

Characterizations of microRNAs involved in the molecular mechanisms underlying the therapeutic effects of noni (Morinda citrifolia L.) fruit juice on hyperuricemia in mice.

Hyperuricemia is generally defined as the high level of serum uric acid and is well known as an important risk factor for the development of various medical disorders. However, the medicinal treatment of hyperuricemia is frequently associated with multiple side-effects. The therapeutic effect of noni (Morinda citrifolia L.) fruit juice on hyperuricemia and the underlying molecular mechanisms were investigated in mouse model of hyperuricemia induced by potassium oxonate using biochemical and high-throughput RNA sequencing analyses. The levels of serum uric acid (UA) and xanthine oxidase (XOD) in mice treated with noni fruit juice were significantly decreased, suggesting that the noni fruit juice could alleviate hyperuricemia by inhibiting the XOD activity and reducing the level of serum UA. The contents of both serum creatinine and blood urine nitrogen of the noni fruit juice group were significantly lower than those of the model group, suggesting that noni fruit juice promoted the excretion of UA without causing deleterious effect on the renal functions in mice. The differentially expressed microRNAs involved in the pathogenesis of hyperuricemia in mice were identified by RNA sequencing with their target genes further annotated based on both Gene Ontology and Kyoto Encyclopedia of Genes and Genomes databases to explore the metabolic pathways and molecular mechanisms underlying the therapeutic effect on hyperuricemia by noni fruit juice. Our study provided strong experimental evidence to support the further investigations of the potential application of noni fruit juice in the treatment of hyperuricemia.

Antioxidant Activity of Noni Juice in Vitro and in Human Volunteers

Morinda citrifolia (noni) fruit juice has been found to provide a wide range of potential health benefits. Among these are the reduction of free radicals and protection against lipid peroxide DNA damage in heavy cigarette smokers and athletes who had exercised to the point of exhaustion. These benefits have been observed after drinking a beverage containing a blend of noni juice from French Polynesia, Tahitian Noni&amp;reg; Juice (TNJ). To determine if TNJ exerts more immediate antioxidant effects, and under less extreme conditions, in vitro tests and a trial involving healthy young adult men were conducted. In the human study, volunteers drank 200 mL TNJ, orange juice or water following an overnight fast. Blood samples were collected before and 1 hour following ingestion of the beverages. Plasma and red cell lysate (erythrocyte) samples were measured for antioxidant activity potentiometrically. TNJ exhibited high in vitro antioxidant activity in the 2,2-diphenylpicrylhydrazyl (DPPH) radical scavenging, reducing power and lipid hydroperoxide scavenging assays. TNJ also significantly increased mean antioxidant activity in plasma and erythrocytes of healthy volunteers. The effect of TNJ in erythrocytes was approximately 4.6 times greater than that of orange juice. There were no increases observed in the water group. The results of this study reveal that TNJ can provide antioxidant benefits shortly after ingestion and under more everyday conditions, not only in extreme circumstances or when consumed repeatedly.

Exploring the Potential Immunomodulatory Properties of Noni Juice on Human Monocytes and Macrophages

Noni, also known as Morinda citrifolia, is a plant that has been widely used for treating various pathologies due to its allegedly anti-inflammatory and immunomodulating properties. Macrophages and monocytes are critical immune cells that initiate inflammation and generate an immune response against various aggressors, regardless of their causative agent. However, it is not well investigated how noni fruit components affect the behavior or phenotype of these cells. Hence, studies in this direction could potentially demonstrate the therapeutic effects of this fruit, which is consumed worldwide. This study aimed to investigate the therapeutic properties of noni fruit juice in modulating the behavior and phenotype of human monocytes and macrophage cells in vitro. The results show that noni fruit juice inhibited the production of nitric oxide (NO) and inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-4, while stimulating the production of the anti-inflammatory cytokine IL-10 in monocytes. In addition, it negatively modulated the expression of toll-like receptor 4 (TLR4). In macrophages, noni fruit juice enhanced the secretion of all cytokines and NO, and inhibited the expression of TLR4. The contrasting results observed could be attributed to the joint stimuli of PMA (Phorbol 12-myristate 13-acetate), which was used to induce macrophage differentiation and noni Juice. Overall, the data indicate that noni may act as an anti-inflammatory agent and may aid in the treatment of uncontrolled inflammatory diseases as a complementary treatment to conventional therapies, under medical supervision.

Desain Kemasan Minuman Sari Buah Mengkudu (Morinda citrifolia) untuk Meningkatkan Pemasaran di UD Manjur Makmur

One of the variant of Morinda citrifolia fruit drink is called noni juice and known as Noni Super Power’s brand name at UD Manjur Makmur. This beverage is naturally fermented by spontaneous fermentation at 28-30°C during six months in a bottle that has been cleaned and tightly closed. During the marketing process to consumers, the design packaging of noni drink is needed to attract consumers buying. Meanwhile, the primary packaging of noni juice at UD Manjur Makmur is less attractive to consumers, there is also no secondary and tertiary packaging and it became the product's packaging weakness. So, label and packaging for noni juice products are needed to design to promote product identity and display product visuals to raise the consumers’ interest. This study was conducted to solve these problems. In this research, benchmarking of products, the Guide on Labeling of Processed Food Agency for National Drug and Food Control (2020), and the observation, imitation, modify methodology were applied. This research resulted in the design of primary, secondary, and tertiary packaging for noni fruit juice drinks. Following the benchmarking, the guide of processed food label requirements, and evaluating the packaging and labels (2020), the new design packaging and labels were better than before. As packaging of noni juice, plastic bottles with new design label are used for primary packaging, followed by rectangles (boxes) made from samson paper (size of 6,3 × 6,3 × 18 cm) for secondary packaging, and cardboard boxes made from corrugate (size of 30 × 20 × 40 cm) for tertiary packaging. Furthermore, the new design packaging (especially tertiary packaging) can accommodate a large amount of noni juice bottles during the marketing and distribution of its product.&#x0D; Keywords: consumers’ interest, noni juice, label, packaging

Production and Evaluation of Fruit Juice Blends from Velvet Tamarind (Dilium Guineese) and Noni Fruit Juice (Morinda Citrifolia)

This study was aimed to explore the production and evaluation of fruit juice blends from velvet tamarind and noni juices. Velvet tamarind fruit was processed to obtain 100% juice (VT sample) while that of noni fruit was also processed to obtain 100% pure juice (N sample). The respective fruit juice blends (N and VT) were formulated: VTN1, VTN2, VTN3, VTN4 at different ratios (20:80%, 40:60%, 60:40%, 80:20%) while N and VT were used as the control. Microbial analysis using pour plate method and sensory evaluation using 9-point hedonic scale were carried out. The blending of these fruit juices gave better sensory quality product with therapeutic effects. The controls VT (100%) was found to be best in all organoleptic attributes (approximately 7.00 = like moderately) and with microbial count of (6.5x103 cfu/g) while control (100%) samples rated worse sensorily. Sample VTN4 rated best followed by VTN3, VTN2, VTN1 respectively. Blending Velvet tamarind (VT) and Noni (N) juices at different proportions result reduce bland taste, unpleasant aroma of noni which improves the organoleptic acceptability of the blends. Noni mellowed down the tartness of velvet tamarind juice thus, obtaining refreshing, therapeutic, vitamin C., … antioxidant, and acceptable organoleptic characteristics of fruit juice blends.

In vitro Inhibition of Dipeptidyl Peptidase-4 (DPP-4) and Arginase by a Dietary Supplement and Its Potential for Improving Quality of Life Factors in Adults

Aim: Somatopause is the progressive and age-related decline of growth hormone (GH) production due to changes in hypothalamic-pituitary axis signaling and results in typical physiological changes associated with the aging process. The purpose of our study was to investigate the anti-aging potential of several botanical ingredients, including noni fruit juice, as well as a dietary supplement formulation.&#x0D; Methodology: Dipeptidyl peptidase-4 (DPP-4) influences hypothalamic-pituitary axis signaling and reduces GH production and secretion. Since DPP-4 concentrations increase with age, we evaluated the ability of several botanical ingredients to inhibit DPP-4 activity in vitro. We subsequently formulated an anti-aging dietary supplement with this blend of botanical ingredients by adding amino acids (L-arginine, L-Lysine, citrulline and beta-alanine), gamma-aminobutyric acid (GABA), flax seed oil and several nutrients. The supplement was evaluated for anti-arginase activity in vitro, as the expression of this enzyme also increases with age. The dietary supplement was also consumed by three men and one woman, ages 56 to 62, with relevant but disparate medical histories. Following short-term ingestion of the supplement, these volunteers were interviewed to ascertain any changes in health status.&#x0D; Results: We discovered that a blend of the botanical ingredients synergistically inhibited DPP-4 in vitro by up to approximately 99%. A concentration-dependent reduction in arginase activity was also observed for the anti-aging dietary supplement. Further, all volunteers reported positive improvements in at least one quality of life factor, which included more restful sleep, reduced musculoskeletal discomfort, increased energy, improved physical stamina and better skin quality.&#x0D; Conclusion: These initial findings suggest that the anti-aging dietary supplement can mitigate declines in quality of life associated with aging by reducing DPP-4 and arginase activities, thereby supporting healthy GH production and endothelial nitric oxide production.

Changes in Phenolic Profiles and Inhibition Potential of Macrophage Foam Cell Formation during Noni (Morinda citrifolia Linn.) Fruit Juice Fermentation

The dynamic changes in phenolic composition and antioxidant activity, and the potential effect on foam cell formation and cholesterol efflux during noni (Morinda citrifolia Linn.) fruit juice fermentation were investigated in this study. The composition of phenolic compounds was significantly different at various fermentation times. Rutin, quercetin, and isoquercitrin were the major phenolics in fermented noni fruit juice based on a quantitative analysis of representative phenolics. The contents of caffeic acid, 2,4-dihydroxybenzoic acid, p-coumaric acid, rutin, and quercetin tended to increase, while those of isoquercitrin decreased during the fermentation process. Fermented noni juice extracts showed high antioxidant activities against 2,2-diphenyl-1-picrylhydrazyl and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid), hydroxyl radical scavenging activity, and ferric reducing antioxidant power. Notably, the highest antioxidant activity was observed after 28 days of fermentation. Furthermore, the treatment of fermented noni juice extracts was shown to reduce foam cell formation, intracellular cholesterol level, and the cholesterol esterification ratio. A correlation analysis indicated a strong positive relationship between the phenolic composition, antioxidant activity, and the ratio of cholesterol ester and total cholesterol. This study may provide a theoretical basis for the quality improvement and standardized production of fermented noni fruit juice, thus promoting the development of the noni food industry.

Fermented noni (Morinda citrifolia L.) fruit juice improved oxidative stress and insulin resistance under the synergistic effect of Nrf2/ARE pathway and gut flora in db/db mice and HepG2 cells.

Oxidative stress interferes with blood glucose homeostasis, leading to insulin resistance (IR) and hyperglycemia, which eventually induce type 2 diabetes (T2DM). Fermented noni (Morinda citrifolia L.) fruit juice (FNJ) is a traditional folk medicine in Polynesia as well as a functional food supplement with a variety of health benefits. In this study, the efficacy and mechanism of FNJ in improving oxidative stress and IR were investigated under the synergistic effect of Nrf2/ARE pathway and gut flora in vivo and in vitro. In vitro, insulin resistant HepG2 cells were established with 50 mM high glucose, and 25 μM rosiglitazone (ROSI) was used as a positive control. In vivo, male C57BLKS mice in the CON group were fed a normal diet and C57BLKS/J-db/db (db/db) mice were treated with 10 mg kg-1 d-1 ROSI and 6.5 and 13 mL kg-1 d-1 FNJ for 8 weeks, respectively. The results showed that 3-5% FNJ markedly improved IR by increasing glucose uptake and consumption and ameliorated oxidative stress via up-regulating the expression of related antioxidant enzymes such as SOD and GPx and attenuating ROS and MDA in IR-HepG2 cells. In vivo, db/db mice exhibited hyperglycemia, hyperinsulinemia, and oxidative stress, whereas FNJ significantly inverted those conditions. Moreover, FNJ supplementation notably increased the gut microbiota diversity of T2DM mice and remodeled the gut microbial composition to suppress microbial disorder. Specifically, FNJ increased the ratio of F/B and lowered the Proteobacteria abundance at the phylum level. The db/db mice were enriched in Enterobacteriaceae, Klebsiella, and Klebsiella-pneumonia, while FNJ feeding significantly up-regulated Rikenellaceae. In addition, western blotting and qPCR experiments showed that FNJ promoted the expression of Nrf2, HO-1, IRS1, PI3K, AKT, and GLUT4 and reduced the JNK level both in vivo and vitro. These results confirmed that FNJ had a protective effect on oxidative stress and IR by activating Nrf2/ARE signaling pathway and regulating gut flora in db/db mice and IR-HepG2 cells.

MicroRNAs Involved in the Therapeutic Functions of Noni (Morinda citrifolia L.) Fruit Juice in the Treatment of Acute Gouty Arthritis in Mice Induced with Monosodium Urate.

We investigated the functions of microRNAs in the therapeutic effects of noni (Morinda citrifolia L.) fruit juice on mouse models of acute gouty arthritis induced with monosodium urate (MSU). Compared with the model group (treated with MSU), mice in both the positive control group (treated with both MSU and colchicine) and noni fruit juice group (treated with MSU and noni fruit juice) showed a significantly decreased degree of paw swelling in 5 days, as well as the contents of two types of proinflammatory cytokines (i.e., NALP3 and TNF-α). Based on the next-generation sequencing technology, a total of 3896 microRNAs (234 known and 3662 novel) were identified in mice treated with noni fruit juice. A large amount of differentially expressed miRNAs were identified in the noni fruit juice group, suggesting the significant effects of noni fruit juice on the mice with acute gouty arthritis, while the different patterns of change in the numbers of both upregulated and downregulated miRNAs in both noni fruit juice and positive control groups indicated that the mice of acute gouty arthritis may be regulated by differential mechanisms between the treatments of noni fruit juice and colchicine. The target genes of microRNAs involved in the pathogenesis and pathology of acute gouty arthritis in mice were identified and further annotated by both Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses. Our results revealed the therapeutic effects of noni fruit juice on acute gouty arthritis in mice with a group of microRNAs involved in the pharmacological mechanisms of noni fruit juice, providing scientific evidence to support both the agricultural cultivation and pharmacological significance of noni plants.
