Network Pharmacology and Molecular Docking Analysis of Morinda citrifolia Fruit Metabolites Suggest Anxiety Modulation through Glutamatergic Pathways.

The fruit of Morinda citrifolia, also known as the noni tree, has been extensively used in Polynesian culture as an alternative medicine to various diseases. Recent studies have pointed out its anxiolytic activity in vitro and in mouse models. Despite the effectiveness of developed anxiolytic drugs in the market, the potential side effects of these medications have led people to resort to traditional medicine such as M. citrifolia. However, evidence regarding its anti-anxiety characteristics is still lacking to this day. Hence, this preliminary study implemented combined network pharmacology and molecular docking to validate its anti-anxiety claims. This study highlighted the bioactive compounds of the M. citrifolia fruit part to have excellent absorption, distribution, metabolism, excretion, and toxicity (ADMET) properties, particularly their outstanding oral bioavailability and blood-brain barrier penetration, both of which are essential considerations to ensure the effectiveness of anxiolytic drugs to arrive at the site of action. Moreover, noni fruit metabolites target genes involved in glutamatergic synapse pathways, which have been significantly associated with anxiety. Through molecular docking, selected compounds exhibited a strong binding affinity towards GRIA2 and PRKCA, both of which have connections with glutamatergic pathways. With all things considered, the results established that the noni fruit potentially contains therapeutic agents that elicit anti-anxiety potential. Through this, the promotion of a more sustainable, accessible, and affordable treatment of anxiety could be developed.

Identifying Potential Human Monoacylglycerol Lipase Inhibitors from the Phytoconstituents of Morinda Citrifolia L. Fruits by in silico Pharmacology and in vitro Study.

Human monoacylglycerol lipase (MGL) is accountable for the hydrolysis of 2-arachidonoylglycerol (2-AG), thus contributing pivotally to neuroprotection because 2-AG is the main source of arachidonic acid, the precursor of prostaglandins production. Inhibiting MGL reduces inflammatory damage in the ischemic brain and enhances cerebral blood flow. Plants have been reported for their neuroprotective effect, such as Morinda citrifolia on pentylenetetrazol (PTZ)-induced kindling seizures in mice, by reducing the seizures and restoring behavioral and biochemical changes, although the mechanism is not described. To evaluate the binding affinity and stability of phytoconstituents in M. citrifolia fruits toward human MGL (PDB ID 3PE6), compared to the known MGL inhibitors (JZL195 and ZYH). The in silico pharmacology study was validated by an in vitro study of the phytosterols and the ethanol extract of M. citrifolia fruits (EEMC) towards MGL. Initially, nine phytoconstituents of M. citrifolia fruits were docked to the catalytic pocket of human MGL (PDB ID: 3PE6), and compounds with the best affinity were subjected to a molecular dynamic (MD) simulation. The in vitro study was performed using the MGL inhibitor screening assay kit. The best binding affinity and stability toward human MGL were shown by stigmasterol and beta-sitosterol, and the MM-PBSA total binding energy of stigmasterol and beta-sitosterol to MGL is stronger than that of JZL195 and ZYH. Moreover, beta-sitosterol and EEMC inhibit MGL with an IC50 value of, respectively, 8.10μg/mL and 196.20μg/mL, while JZL195 shows an IC50 of 0.028μg/mL. Beta-sitosterol of Morinda citrifolia fruits may have the potential to protect human neurons by occupying the catalytic site of human MGL, thus competitively inhibiting the substrate of the enzyme. However, the inhibitory activity towards human MGL is lower than JZL195.

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.

An evidence-based review of Morinda citrifolia L. (Rubiaceae) fruits on animal models, human studies, and case reports

Context: Morinda citrifolia L. (Rubiaceae), commonly known as noni, is widely used as a complementary and alternative therapy in many countries due to its numerous beneficial effects on health. Aims: To thoroughly analyze the efficacy and safety of M. citrifolia fruit across all reported areas. Methods: The articles were explored on the PubMed and Cochrane Library databases using a combination of keywords: Morinda citrifolia AND human studies; Morinda citrifolia AND pharmacological activities using PRISMA guidelines. Results: Studies in animal models revealed its activity as anti-dyslipidemia, anti-lipogenesis, anti‑fungal, hepatoprotective, hypotensive, immunostimulatory, anti-alopecia, photoprotective, antitumor, antiviral, anticancer, antidopaminergic, and antimicrobial. Based on the clinical and efficacy evidence, it is apparent that M. citrifolia is a potentially valuable medicinal plant whose status should be upgraded from laboratory bench to bedside. The safety of M. citrifolia has been confirmed and proven by no occurrence of AEs or only mild gastrointestinal discomforts. However, five cases of male and female patients aged from 14 to 63 years old reported different symptoms, such as fatigue, headache, vomiting, pigmentation, or acute hepatitis, after a high-dose daily use of this supplement. Conclusions: Taking everything into consideration, M. citrifolia, despite its mild adverse events, has a beneficial efficacy and safety as an antioxidant; nevertheless, caution and therapy drug monitoring is required if this plant is to be taken in a long-term period.

Noni enhances the anticancer activity of cyclophosphamide and suppresses myelotoxicity and hepatotoxicity in tumor-bearing mice

Background and aimMorinda citrifolia fruit juice (noni) is an herbal remedy documented to have antioxidant properties. It has been suggested that prevention of carcinogen-DNA adduct formation and the antioxidant activity of NJ may contribute to the cancer preventive effect. In the present study, the antitumor activity of noni was investigated in the presence of cyclophosphamide (CYL) in vitro and in vivo.MethodsIn vitro breast cancer cells (MDA-MB-468) were used to measure the percentage of inhibition and the IC50. The in vivo antitumor activity of noni was studied by monitoring the mean survival time (MST), percentage increase in life span (%ILS), viable and non-viable cell count, tumor volume, body weight, and hematological and serum biochemical parameters in mice. Treatment with noni and CYL exhibited dose- and time-dependent cytotoxicity toward breast cancer cells.ResultsIndividual treatment of noni and CYL exhibited dose- and time-dependent cytotoxicity on breast cancer cell lines, while in combination therapy of noni and CYL, noni enhances cytotoxic effect of CYL at 48 h than that at 24 h. Similar result was found in in vivo studies, the results of which revealed that alone treatment of CYL and noni suppressed tumor growth. However, combination treatment with CYL and noni presented better tumor inhibition than that of alone treatment of CYL and noni. On the contrary, CYL alone drastically attenuated hematological parameters, i.e., RBC, WBC, and Hb compared to normal and control groups, and this change was reversed and normalized by noni when given as combination therapy with CYL. Moreover, the levels of serum biochemical markers, i.e., AST, ALP, and ALT, were significantly increased in the control and CYL-treated groups than those in the normal group. In the combination treatment of noni and CYL, the above biochemical marker levels significantly decreased compared to CYL alone-treated group.ConclusionsThe present study suggested that CYL treatment can cause serious myelotoxicity and hepatic injury in cancer patients. In conclusion, the combined use of noni with CYL potentially enhances the antitumor activity of CYL and suppresses myelotoxicity and hepatotoxicity induced by CYL in tumor-bearing mice.

Effect of Morinda citrifolia (Noni) Fruit Extract on the Teratogenecity in Female Wistar Rats

The raw fruit extract of Morinda citrifolia plant and its commercially available formulation in the market as Noni max (Best-selling brand of Brihans pharmaceutical in India and abroad) were obtained from Brihans Pharmaceuticals Pvt. Ltd. Mulund, Mumbai, India. 80 Wistar rats of either sex weighing between 200 to 250 gms were used for experimentation. In the present study, it was found that the Morinda citrifolia fruit extract and its formulation found safe for the developmental stages of foetus. It was also found that there was no significant difference was noted in body weight and the relative weight of the ovary, uterus and placenta of female rat. There was no structural and functional manifestation was noted in the developing foetusin the pregnant female rats. From the present study it is confirm that, both Morinda citrifolia fruit extract and its formulation (Noni max) did not produce any teratogenic effect in rats up to 1000 mg/kg and 40 ml/kg respectively.

Morinda citrifolia fruit extract enhances the resistance of Penaeus vannamei to Vibrio parahaemolyticus infection

Vibrio parahaemolyticus is a gram-negative facultative anaerobic bacterium implicated as the causative agent of several shrimp diseases. As part of the effort to provide biocontrol and cost-effective treatments, this research was designed to elucidate the effect of Morinda citrifolia fruit extract on the immunity of Penaeus vannamei postlarvae (PL) to V. parahaemolyticus. The methanol extract of M. citrifolia was vacuum evaporated, and the bioactive compounds were detected using gas chromatography‒mass spectrometry (GC‒MS). Thereafter, P. vannamei PL diets were supplemented with M. citrifolia at different concentrations (0, 10, 20, 30, 40, and 50 mg/g) and administered for 30 days before 24 h of exposure to the bacterium V. parahaemolyticus. A total of 45 bioactive compounds were detected in the methanol extract of M. citrifolia, with cyclononasiloxane and octadecamethyl being the most abundant. The survival of P. vannamei PLs fed the extract supplement was better than that of the control group (7.1–26.7% survival greater than that of the control group) following V. parahaemolyticus infection. Shrimp fed 50 mg/g M. citrifolia had the highest recorded survival. The activities of digestive and antioxidant enzymes as well as hepatopancreatic cells were significantly reduced, except for those of lipase and hepatopancreatic E-cells, which increased following challenge with V. parahaemolyticus. Histological assessment of the hepatopancreas cells revealed reduced cell degeneration following the administration of the plant extracts (expecially those fed 50 mg/g M. citrifolia) compared to that in the control group. Therefore, the enhanced immunity against V. parahaemolyticus infection in P. vannamei could be associated with the improved hepatopancreas health associated with M. citrifolia fruit extract supplementation.

Antifungal Activity of Morinda citrifolia Methanolic Extract against Candida albicans: An In Vitro Study.

Natural medicine used as an alternative and/or complementary treatment to counteract diseases is of great importance in public health. Therefore, the purpose of the present study was to assess the in vitro antifungal activity of Morinda citrifolia methanolic extract of peel, pulp, and seed against Candida albicans. The present study was experimental in vitro and cross-sectional. Eight replicates were prepared in Sabouraud dextrose agar with five wells each, where 0.12% chlorhexidine, distilled water, and methanolic extract of seed, peel, and pulp of Morinda citrifolia fruit were placed at concentrations of 10,690, 8,270, and 6,430 mg/mL, respectively, to evaluate sensitivity according to Duraffourd's scale. In addition, the minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) were determined by dilution and agar seeding method. Statistical analysis was performed by analysis of variance (ANOVA) and Tukey's post hoc test, considering a significance level of P < 0.05. The inhibition halos of Morinda citrifolia methanolic extract of seed, peel, and pulp against Candida albicans measured on average 15.94, 11.94, and 11.56 mm, respectively. The MIC of seed, peel, and pulp extract were 1366.25, 2067.5, and 1607.5 mg/mL respectively, whereas the MFC for seed, peel, and pulp extract were 2672.50, 2067.5, and 3215 mg/mL, respectively. Moreover, seed extract presented significantly higher antifungal activity than peel and pulp (P < 0.001). Morinda citrifolia methanolic extract of peel, pulp, and seed showed fungistatic and fungicidal effect against Candida albicans, being this very sensitive to seed extract with a MIC of 1366.25 mg/mL and a MFC of 2672.5 mg/mL, which allows recommending the development of effective pharmacological formulations for the control of candidiasis.

Simultaneous use of Morinda citrifolia fruit extract and amlodipine: Antihypertensive activity and sub-chronic toxicity in rats

This study investigates the effects of the simultaneous use of Morinda citrifolia fruit extract (MCFE) and amlodipine (AML) on rats’ antihypertensive activity and sub-chronic toxicity. The antihypertensive activity was assessed in 25 male Wistar rats divided into 5 groups: 1. normal, 2. negative control (NaCl 8%), 3. positive control [NaCl 8% + AML 1 mg/kg body weight (BW)], 4. Treatment-1 [NaCl 8% + MCFE (45 mg/kg BW)], and 5. Treatment-2 [NaCl 8% + MCFE (45 mg/kg BW) + AML (1 mg/kg BW)]. MCFE and AML were given orally on days 22–35. The blood pressure was measured on days 0, 7, 21, 28, and 35. The sub-chronic toxicity study was conducted with a repeated dose 28-day oral toxicity test. The results showed that the blood pressure reduction in the treatment-2 group was not significantly different from those in the positive control or treatment-1 group (p &gt; 0.05). In addition, it changed aspartate aminotransferase, alanine transaminase, Blood urea nitrogen, creatinine levels, and histological parameters in the liver and kidneys. The simultaneous use of MCFE and AML might have the same activity as either AML or MCFE alone but could cause toxic effects on liver and kidney function. Therefore, simultaneous use should not be considered for hypertension therapy.

The influence of Morinda citrifolia fruit maturity level, parts and storage length on total phenols, ascorbic acid, antioxidant activity and ethylene gas emission

Different parts of noni plant (Morinda citrifolia) were analyzed for total phenols, total ascorbic acid and antioxidant activity at three different maturities. Results showed higher total phenols content (TPC) in seeds (9.63–12.48) than in pulp (4.47–8.69), and leaves (3.55–6.51 mg GAE/g−1 DW). Ascorbic acid content ranged between 0.21–0.90, 0.23–0.97 and 0.30–0.69 mg g−1 for pulp, skin and leaves respectively. Immature fruits had higher TPC and higher antioxidant activity than mature ripe fruits and leaves. Total ascorbic acid content was highest (P < 0.05) in the seeds (1.31–1.79 mg g−1). Mature ripe fruits should be harvested for high ascorbic acid contents. For functional benefits and medicinal use, mature green fruits are recommended for the best antioxidant potential and phenol content. Longer storage resulted in higher ethylene biosynthesis which correlated inversely to total phenols content (-0.92) and antioxidant activity (-0.92). Further compositional and in vivo analyses of noni plant parts is suggested.

The Effect of Morinda citrifolia Ethanolic Extract against Malassezia globosa Obtained from the Scalp of Individuals between the Ages of 18-24 in Georgetown, Guyana

Dandruff, a common scalp condition affecting 50% of the world’s population, is mainly caused by the fungus M. globosa. In this study, the antifungal effect of M. citrifolia, commonly known as noni, was tested against M. globosa. M. citrifolia fruit, leaf, and stem contain phytochemicals including alkaloids, phenols, flavonoids, and glycosides. Extracts of the three plant parts were obtained by maceration method using ethanol, and prepared in concentrations of 100%, 75%, 50% and 25%. The scalps of 6 individuals were swabbed to obtain a sample of M. globosa. The susceptibility of M. globosa to M. citrifolia extracts was tested in triplicate using the disc diffusion method, and a measure of the extent of susceptibility was ascertained by the size of the inhibition zones. It was found that of the 3 extracts, noni fruit showed the highest inhibitory effect with 20/48 discs having inhibition zones, noni stem showed moderate inhibition with 12/48 inhibition zones, while noni leaf exhibited no inhibition zones, indicating its lack of inhibitory effect against M. globosa. Notably, noni fruit at 100% and 75% concentrations proved to be most effective against M. globosa, and at 25% concentrations, noni stem was most effective. However, statistical analysis using both ANOVA and Kruskal Wallis tests indicated that the observed data was insignificant since the p-values were &gt; 0.05. It can therefore be concluded that noni fruit, leaf, and stem extracts have little to no significant inhibitory effect on the growth of M. globosa, notwithstanding, a change in various experimental factors including agar type and extract preparation may prove otherwise.

Effect of Morinda citrifolia fruit powder on physiological and productive performance of Cavia porcellus.

The breeding of guinea pig is part of the pluriactivity for millions of farming families in rural areas from the Peruvian Andean and Amazonian regions and other South American Andean countries. Rearing these specie plays an important source of employment, income, and nutrition for millions of rural families on these countries. The search of natural products for enhancing animal wellbeing, health, and production and thereby of guinea pigs is being searched nowadays. The aim of this study was to determine the effect of the ripe fruit powder of Morinda citrifolia on the physiological and productive performance parameters of reared guinea pigs under humid tropical conditions and to find a new use of noni fruit and to improve the guinea pig as an agrifood product. For this purpose, forty-eight male Peru breed guinea pigs sixty days old, were used and distributed into four treatments with diets containing 0, 2, 4 and 8% of the noni ripe fruit powder, with four replicates and 3 guinea pigs each. Erythrocytes, hematocrit, hemoglobin profiles, hematological indices MCV (mean cell volume), MCHC (mean corpuscular hemoglobin concentration), MCH (mean corpuscular hemoglobin) and blood metabolites profiles: TP (total protein), ALB (albumin), GLO (globulin), TC (total cholesterol) were determined. The productive performance indices: DWG (daily weight gain), DCFI (daily concentrated feed intake), TFIFM (total feed intake of fresh matter) and TFIDM (total feed intake of dry matter), FRCFM (feed rate conversion for fresh mater) and FRCDM (feed rate conversion for dry matter) were evaluated. The guinea pigs were evaluated at 60, 75 and 90 days old. The interaction between noni fruit powder and the age of guinea pigs produced an increase in the erythrocyte, hematocrit, MCH and MCHC levels at 75 days old, (p < 0.05). The final weight and the daily weight gain increased, while the feed rate conversion for fresh and dry matter decreased, as the level of noni fruit powder in the diet increased until 4% (p < 0.05). Thus, the level of noni ripe fruit powder in the guinea pigs' diets had a positive effect on the erythrocyte, leucocytes, hematocrit, MCH, MCHC levels, the final weight, the daily weight gain, and the feed rate conversion of fresh and dry matter.

Evolution of fatty acid taste in drosophilids

Comparative studies of related but ecologically distinct species can reveal how the nervous system evolves to drive behaviors that are particularly suited to certain environments. Drosophila melanogaster is a generalist that feeds and oviposits on most overripe fruits. A sibling species, D.sechellia, is an obligate specialist of Morinda citrifolia (noni) fruit, which is rich in fatty acids (FAs). To understand evolution of noni taste preference, we characterized behavioral and cellular responses to noni-associated FAs in three related drosophilids. We find that mixtures of sugar and noni FAs evoke strong aversion in the generalist species but not in D.sechellia. Surveys of taste sensory responses reveal noni FA- and species-specific differences in at least two mechanisms-bitter neuron activation and sweet neuron inhibition-that correlate with shifts in noni preference. Chemoreceptor mutant analysis in D.melanogaster predicts that multiple genetic changes account for evolution of gustatory preference in D.sechellia.

Investigation of Morinda citrifolia Activity Related Collagen Type II Synthesis Through Gene Expression

To extend plant benefits, three different concentrations of five Morinda citrifolia part was investigated on the collagen type II which is the primary collagen in human cartilage through the expression of the genes, COL2A1, COL-II and COLL2 regions in normal human dermal fibroblasts by qRT-PCR method. The results showed that 1) fibroblasts cultured in the presence of M. citrifolia extracts produced many times more collagen type II gene expression than control cells depending on the plant parts and concentrations, 2) the expression levels of the collagen type II gene stimulated by all fruit parts yields the higher percentages than leaves. Next, Morus alba leaf extract at a concentration expected to be a precursor protein source for collagen synthesis, working together with M. citrifolia stimulation, was added to the selected concentration indicating high expression in the M. citrifolia fruit experiments. The result showed various gene expression levels depended on the kind of gene and fruit part. Therefore, M. citrifolia fruits can benefit the creation of collagen type II with or without M. alba. The M. citrifolia fruit can be further benefited in product production for both the elderly and young for maintaining the typical structure and function of the skin, tendon, and bone.

Molecular dynamics study of stigmasterol and beta-sitosterol of Morinda citrifolia L. towards α-amylase and α-glucosidase

Previous in vivo studies of Morinda citrifolia (Rubiaceae) reported that the extract inhibited α-amylase and reduced blood glucose levels in streptozotocin-induced diabetes mice. Moreover, molecular docking studies confirmed that ursolic acid and sterol compounds contained in the fruit interacted with important residues in the binding site of α-amylase and α-glucosidase. Our work aimed to study the complex stability of stigmasterol (which has been isolated from the M. citrifolia fruit for the first time) and beta-sitosterol towards α-amylase and α-glucosidase by employing molecular dynamics simulation on GROMACS 2016.3 embedded with the AMBER99SB-ILDN force field. The simulation was carried out for 100 ns at 310 oK. Based on the RMSD and RMSF graphs, the complexes of stigmasterol/α-amylase and stigmasterol/α-glucosidase are more stable compared to acarbose, the known inhibitor of both enzymes. Moreover, beta-sitosterol indicates a better stability complex with α-glucosidase compared to that of acarbose. Interestingly, the affinity of stigmasterol and beta-sitosterol to both enzymes, in terms of the total binding energy, is stronger than that of acarbose. Taken together, stigmasterol and beta-sitosterol in M. citrifolia fruit may have the potency to be developed as α-amylase and α-glucosidase inhibitors. Communicated by Ramaswamy H. Sarma

Evaluation of phytochemicals from Morinda citrifolia (Noni) fruit extracts against nicotine-induced different physiological functions: An experimental study on albino rat model

Background: People are consuming nicotine in the form of cigars, pipes and, cigarettes etc. and they are suffering from lungs, liver, heart diseases, involving hidden killer for human health. The Morinda citrifolia (Noni) is an important medicinal plant of the Rubiaceae family, commonly known as Ach, Bartundi, Hurdi and Sarangi in Bengali. Traditionally it is used in various purposes of food and medicines.Aims and objectives: The present study was undertaken to highlight and find out the different phytochemicals from noni fruit extractand its role against nicotine-induced cardiac damage, mainly serum lipid profile and hematological changes and development of biobased anti-nicotinic agent is now become an active research goal.Materials and methods: Fruits of the selected plant was collected and prepared methanolic fruit extract.

This studyrevealed that the fruits extract of M. citrifolia may be capable of reducing the cholesterol and hemoglobin levels significantly (p&lt;0.05)in blood after nicotine treatment in rat models.Conclusion: So, we try to find out the role of active principles and phytochemicals from this plant to combat the nicotinic activity.Results show that Noni fruit methanolic extract may have some protective effects against nicotine and its action.

Genetic variation in disease resistance in Drosophila spp. is mitigated in Drosophila sechellia by specialization to a toxic host

We found that Drosophila species vary in their susceptibility to the broad-spectrum entomopathogen, Metarhizium anisopliae (strain Ma549). Generalist species were generally more resistant than dietary specialists, with the cactophilic Drosophila buzzatii and Drosophila sechellia, a specialist of the Morinda citrifolia (Morinda) fruit, being most susceptible. Morinda fruit is reported to be toxic to most herbivores because it contains Octanoic Acid (OA). We confirmed that OA is toxic to Drosophila spp., other than D. sechellia, and we also found that OA is highly toxic to entomopathogenic fungi including Ma549 and Beauveria bassiana. Drosophilasechellia fed a diet containing OA, even at levels much less than found in Morinda fruit, had greatly reduced susceptibility to Ma549. This suggests that specializing to Morinda may have provided an enemy-free space, reducing adaptive prioritization on a strong immune response. Our results demonstrate that M. anisopliae and Drosophila species with divergent lifestyles provide a versatile model system for understanding the mechanisms of host–pathogen interactions at different scales and in environmental context.

Chemical composition and antifungal activity of Morinda Citrifolia fruit extract

Noni (Morinda citrifolia) fruit is a well-known plant used as a traditional medicine for preventing some diseases because of its abundance in chemical compounds. This research aimed to determine the phytochemical concentration, chemical composition, and antifungal activity of M. citrifolia fruit extract. M. citrifolia fruit was extracted with methanol and then distilled water for the partition extract. Subsequently, the extract was fractionated using various nonpolar to polar solutions, such as; chloroform, ethyl acetate, water, 2-propanol, and methanol fractions. Each fraction was evaporated until the dry extract was released. Additionally, the photochemical concentration of the M. citrifolia fruit extract was quantitatively determined using a UV-visible spectrophotometer. The chemical composition of the M. citrifolia fruit extract of each fraction was identified using gas chromatography-mass spectrometry (GC-MS). Then, the antifungal activity of M.citrifolia fruit extract against C. albicans and C. krusei was determined using the disc diffusion method. The results showed that the phytochemical concentration of the M. citrifolia fruit extract was 1970.25 ppm flavonoids, 35.61 ppm tannins, and 148.62 ppm steroids. 2-Fluorobenzoic acid, eucalyptol, 2-chloroaniline-5-sulfonic acid, hexa-decamethyl octasiloxane, and tetra-propyl stannane were found to be the major components of M. citrifolia fruit extract. According to the research, M. citrifolia fruit extract showed antifungal activity against C. albicans and C. krusei in all tested fractions. The maximum inhibition zone of C. albicans was 14.0 ± 1.00 mm in the 2-propanol fraction, while that of C. krusei was 11.7 ± 0.58 mm in the methanol fraction.
