Effect of the Capsicoside G-rich Fraction from Pepper (Capsicum annuum L.) Seeds on High-fat Diet-induced Obesity in Mice.

Obesity is one of the most common metabolic syndromes and is a major threat to human health worldwide. Given the size of this problem, there is growing interest in natural agents that may decrease obesity. In this study, we investigated the anti-obesity effect of a capsicoside G-rich fraction (CRF; 13.35% capsicoside G) isolated from pepper seeds in diet-induced obese mice. C57BL/6J mice were fed either a normal diet or a high-fat diet (HFD), with or without CRF (HFD + CRF; 10 and 100 mg/kg body weight). The body weight and food efficiency ratio of mice fed HFD + CRF were lower in comparison to that of mice fed only an HFD. Epididymal adipose tissue weight and adipocyte hypertrophy were significantly lower in HFD + CRF mice than in HFD mice. The fat deposition in the liver of mice fed HFD + CRF was lower compared to that of mice fed only an HFD. CRF significantly reversed the HFD-induced elevation of the expression of key adipocyte differentiation regulators, including peroxisome proliferator-activated receptor γ, CCAAT/enhancer-binding protein α, sterol regulatory element binding protein 1c, and their target genes. These results suggest that CRF could be used as dietary therapy for the prevention of obesity and obesity-related metabolic diseases. Copyright © 2016 John Wiley & Sons, Ltd.

Optimal extraction conditions and quantification of lignan phytoestrogens in cereal grains using targeted LC-MS/MS.

Lignans are phytoestrogens found in various forms such as glycosides, ester-linked oligomers, and aglycones in a variety of foods, including soy products, legumes, grains, nuts, vegetables, and fruits. This study aimed to optimize the extraction of lignans from cereal grains using response surface methodology (RSM). Lignans, including secoisolariciresinol (Seco), matairesinol (Mat), pinoresinol (Pin), lariciresinol (Lar), and syringaresinol (Syr), were quantified using high-performance liquid chromatography-tandem mass spectrometry. A Box-Behnken design was employed to determine the optimal values for three extraction parameters: temperature (X1: 20°C-60°C), methanol concentration (X2: 60%-100%), and extraction time (X3: 30-90 min). The highest lignan contents were obtained at X1 = 44.24°C, X2 = 84.64%, and X3 = 53.63 min. To apply these experimental conditions to the actual experiment, the optimal conditions were slightly adjusted to X1 = 40°C, X2 = 80%, and X3 = 60 min. The predicted results closely matched the experimental results obtained using the modified optimal extraction conditions. The highest lignan content found in barley sprouts (85.930 µg/100 g), however, most grains exhibited relatively low concentrations of lignans. These findings provide valuable insights into the lignan content of grains and contribute to the generation of reliable data in this field.

Comparative Analysis of Polyphenolic Compounds in Different Amaranthus Species: Influence of Genotypes and Harvesting Year.

Amaranth is a nutritionally valuable crop, as it contains phenolic acids and flavonoids, yielding diverse plant secondary metabolites (PSMs) like phytosterol, tocopherols, and carotenoids. This study explored the variations in the contents of seventeen polyphenolic compounds within the leaves of one hundred twenty Amaranthus accessions representing nine Amaranthus species. The investigation entailed the analysis of phenolic content across nine Amaranthus species, specifically A. hypochondriacus, A. cruentus, A. caudatus, A. tricolor, A. dubius, A. blitum, A. crispus, A. hybridus, and A. viridis, utilizing ultra performance liquid chromatography with photodiode array detection (UPLC-PDA). The results revealed significant differences in polyphenolic compounds among accessions in which rutin content was predominant in all Amaranthus species in both 2018 and 2019. Among the nine Amaranthus species, the rutin content ranged from 95.72 ± 199.17 µg g-1 (A. dubius) to 1485.09 ± 679.51 µg g-1 (A. viridis) in 2018 and from 821.59 ± 709.95 µg g-1 (A. tricolor) to 3166.52 ± 1317.38 µg g-1 (A. hypochondriacus) in 2019. Correlation analysis revealed, significant positive correlations between rutin and kaempferol-3-O-ß-rutinoside (r = 0.93), benzoic acid and ferulic acid (r = 0.76), and benzoic acid and kaempferol-3-O-ß-rutinoside (r = 0.76), whereas gallic acid showed consistently negative correlations with each of the 16 phenolic compounds. Wide variations were identified among accessions and between plants grown in the two years. The nine species and one hundred twenty Amaranthus accessions were clustered into six groups based on their seventeen phenolic compounds in each year. These findings contribute to expanding our understanding of the phytochemical traits of accessions within nine Amaranthus species, which serve as valuable resources for Amaranthus component breeding and functional material development.

Relationships between sensory properties and metabolomic profiles of different apple cultivars.

Flavor is a critical factor in apple quality. To better understand apple flavor, this study aimed to identify the relationships between sensory attributes and the chemical composition (volatiles and non-volatiles) of apples using a combined metabolomic and sensory evaluation. Sensory results showed the positive (apple, fruity, pineapple, sweetness, sourness) and negative (cucumber) flavor attributes of apples. A metabolomic analysis with statistical correlations revealed significant metabolites related to the flavor attributes of apples. Volatile esters (e.g., hexyl acetate and 2-methylbutyl acetate for apple and fruity notes) and non-volatile sugars and acids (total sugars, tartaric acid, and malic acid for balanced sweet and tart flavors) were associated with the apple flavor preferred by consumers. Some aldehydes and alcohols (e.g., (E)-2-nonenal) contributed to a negative hedonic perception (cucumber). The collected information demonstrated the roles of key chemical compounds in apple flavor quality, and may be applicable to quality control.

Sucrose-induced abiotic stress improves the phytochemical profiles and bioactivities of mung bean sprouts.

This study aimed to examine the impact of sucrose treatment on the growth conditions, dietary nutritional quality, and biological activities of mung bean sprouts. Mung bean seeds were sprouted with solutions containing different sucrose concentrations (10, 20, and 30 g/L). The application of exogenous sucrose significantly decreased the height and fresh weight of mung bean sprouts. However, the sucrose-treated sprouts contained more polyphenols, flavonoids, γ-aminobutyric acid, phytosterols, and vitamins. The antioxidant capacities were also significantly higher in the sucrose-treated sprouts than in the control sprouts. The sprouts treated with 2-3 % sucrose showed markedly improved FFA-induced insulin resistance and alcohol-induced oxidative injury in HepG2 cells. Taken together, the elicitor application of sucrose at 3 % during mung bean sprouting could be an effective strategy to improve the dietary phytochemical composition and provide potential health benefits.

A novel physiological function of pheromone biosynthesis-activating neuropeptide in production of aggregation pheromone.

The western flower thrips, Frankliniella occidentalis, is an insect pest, and its aggregation pheromone (AP) plays a crucial role in the recruitment of both sexes. A novel pheromone biosynthesis-activating neuropeptide (PBAN)-like gene is encoded in F. occidentalis genome, but its physiological function has yet to be elucidated. This study hypothesized the physiological role played by PBAN in mediating AP production. AP has been known to be produced only by male adults in F. occidentalis. Surprisingly, our extraction of headspace volatiles contained two AP components in females as well as in males with similar composition. PBAN injection elevated the AP production whereas RNA interference (RNAi) of the gene expression suppressed the AP production in both sexes. A biosynthetic pathway to produce AP components were predicted and the enzymes catalyzing the main steps were confirmed in their expressions. Individual RNAi treatments of these genes significantly suppressed AP production. RNAi of PBAN gene downregulated the expressions of these biosynthesis-associated genes in both sexes. These results suggest that the novel neuropeptide acts as PBAN mediating AP production through stimulating its biosynthetic machinery in F. occidentalis.

Metabolomic analysis reveals linkage between chemical composition and sensory quality of different floral honey samples.

Honey has a distinct flavor characterized by various volatiles and non-volatiles from diverse origins. In this study, metabolomics combined with sensory analysis was performed to identify relationships between chemical profile and sensory quality of honey. Targeted metabolomic analysis was conducted to determine volatile and non-volatile profiles of seven different honey. Volatile profile was analyzed using headspace solid-phase microextraction (HS-SPME) coupled to GC - MS. LC - MS/MS, HPLC - UV, and HPLC-RI were employed to analyze flavonoids, organic acids, and sugars, respectively. Authentic standards were utilized for confirmation of metabolites. Sensory evaluation included quantitative descriptive analysis and consumer acceptance test. The results showed that sucrose (sweetness) was responsible for a positive hedonic perception, while organic acids and flavonoids (sourness, astringency, bitterness) negatively affected consumer acceptance. Volatiles with floral notes (e.g. decyl formate) were preferred, but others with off-flavors (e.g. 2-methylbenzofuran) were not preferred by consumers. Flavor familiarity was strongly correlated with the consumer acceptance of honey, indicating that the balance between volatiles and non-volatiles is significant for honey flavor quality. This work demonstrates the role of key flavor compounds in honey quality, and may be applicable to the quality control of honey.

Pathway-Based Metabolomics Analysis Reveals Biosynthesis of Key Flavor Compounds in Mango.

Mango is a tropical fruit with global demand as a result of its high sensory quality and nutritional attributes. Improving fruit quality at the consumer level could increase demand, but fruit quality is a complex trait requiring a deep understanding of flavor development to uncover key pathways that could become targets for improving sensory quality. Here, a pathway-based metabolomics (untargeted and targeted) approach was used to explore biosynthetic mechanisms of key flavor compounds with five core metabolic pathways (butanoate metabolism, phenylalanine biosynthesis and metabolism, terpenoid backbone biosynthesis, linoleic and linolenic acid pathway, and carbon fixation and sucrose metabolism) in three mango cultivars. The relationships between flavor precursors and flavor compounds were identified using correlation analysis. With these novel strategies, differentially regulated metabolic flux through the pathways was first elucidated, demonstrating possible mechanisms of key flavor formation and regulation in mango fruits.

Volatile Compositions of Panax ginseng and Panax quinquifolium Grown for Different Cultivation Years.

The present study examined the volatile profiles of Panax ginseng (Korean ginseng) and Panax quinquefolium (American ginseng) grown for different cultivation years by using HS-SPME/GC-MS and determined the key discriminant volatile compounds by chemometric analysis including principal component analysis (PCA), hierarchical cluster analysis (HCA), and partial least squares-discrimination analysis (PLS-DA). Fifty-six compounds, including forty terpenes, eight alcohols, one alkane, one ketone, and one furan, were identified in the ginseng roots. The chemometric results identified two major clusters of American ginseng and Korean ginseng cultivars with distinct volatile compositions. The volatile compounds in fresh white ginseng roots were affected by the species, but the influence of different cultivation ages was ambiguous. The major volatile components of ginseng roots are terpenes, including monoterpenes and sesquiterpenes. In particular, panaginsene, ginsinsene, α-isocomene, and caryophyllene were predominant in Korean ginseng cultivars, whereas ß-farnesene levels were higher in American ginseng. The difference in volatile patterns between Panax ginseng and Panax quinquefolium could be attributed to the composition of sesquiterpenes such as ß-panaginsene, ginsinsene, caryophyllene, and ß-farnesene.

Plum Prevents Intestinal and Hepatic Inflammation in the Acute and Chronic Models of Dextran Sulfate Sodium-Induced Mouse Colitis.

SCOPE: Inflammatory bowel disease (IBD), including ulcerative colitis (UC), is a chronic recurrent inflammatory disease of the digestive tract and increases the risk of colon cancer. METHOD AND RESULTS: This study evaluates the effects of dietary intervention with freeze-dried plum (FDP), a natural antioxidant and anti-inflammatory fruit with no toxicity on dextran sulfate sodium (DSS)-induced acute and chronic experimental colitis in a mouse model and studies the molecular mechanisms of protection through the gut-liver axis. The results show that FDP decreases the levels of inflammatory mediators, which is a nitrative stress biomarker in both acute and chronic models. FDP markedly reduces DSS-induced injury to the colonic epithelium in both acute and chronic models. In addition, FDP significantly decreases the levels of pro-oxidant markers such as CYP2E1, iNOS, and nitrated proteins (detected by anti-3-NT antibody) in DSS-induced acute and chronic colonic injury models. Furthermore, FDP markedly reduces markers of liver injury such as serum ALT/AST, antioxidant markers, and inflammatory mediators in DSS-induced acute and chronic colonic injury. CONCLUSION: These results demonstrate that the FDP exhibits a protective effect on DSS-induced acute and chronic colonic and liver injury through the gut-liver axis via antioxidant and anti-inflammatory properties.

Protective Activity and Underlying Mechanism of Ginseng Seeds against UVB-Induced Damage in Human Fibroblasts.

Ginseng seeds are rich in phytosterols, ginsenosides, and fatty acids, and can therefore be used in skincare to delay the aging process. Ginseng seed embryo (GSE) and ginseng seed coat (GSC) were separated from ginseng seeds (Panax ginseng Meyer). This study evaluated the protective activity and underlying mechanism of GSE and GSC on UVB irradiation-induced skin photoaging using Hs68 cells. Their bioactive compounds, including phytosterols, ginsenosides, tocopherols, tocotrienols, and fatty acids were determined by HPLC and GC. The levels of reactive oxygen species, matrix metalloproteinases (MMPs), and collagen levels were measured in human dermal fibroblast cell line, Hs68 cells. The antioxidant capacity and contents of total polyphenols and flavonoids were higher in GSC than those in GSE. Linoleic acid was the major fatty acid in both GSE and GSC. GSE and GSC treatment alleviated UVB-induced increase of reactive oxygen species (ROS), matrix metalloproteinase (MMP)-1, and MMP-3, resulting in reduced collagen degradation. Increased UVB-mediated phosphorylation of mitogen activated protein kinase (MAPK) and activator protein-1 (AP-1) was inhibited by GSE and GSC treatment. Moreover, GSE and GSC effectively upregulated transforming growth factor-ß (TGF-ß) 1 levels. It was found that ginseng seeds regulate the expression of TGF-ß/Smad and MAPK/AP-1 pathways. Ginseng seeds contain various bioactive compounds and have protective activity against UVB-induced skin photoaging. Therefore, ginseng seeds have the potential for use in cosmeceutical preparations.

Inhibitory effect of diosmetin on inflammation and lipolysis in coculture of adipocytes and macrophages.

The interaction between adipocytes and macrophages in obese tissues plays a critical role in the onset of metabolic syndromes. This study aimed to evaluate the modulatory effect of diosmetin on anti-inflammatory and anti-lipolytic activities in the coculture of macrophages and adipocytes. The secretion of inflammatory mediators increased in a coculture medium, however, diosmetin significantly reduced the levels of these inflammatory mediators such as nitric oxide (NO), tumor necrosis factor-α, and monocyte chemoattractant protein. Diosmetin down-regulated the protein expression of inducible NO synthase in cocultured macrophages and adipocytes, and inhibited the phosphorylation of mitogen-activated protein kinases and the translocation of p65 and p50 to the nucleus. Moreover, it suppressed the phosphorylation of hormone-sensitive lipase and the production of fatty acid-binding protein 4, and increased the mRNA expression of adiponectin in cocultured adipocytes by 18%-35%. These results indicate that diosmetin inhibited inflammation and lipolysis in the crosstalk between adipocytes and macrophages; diosmetin-containing foods could be used in dietary therapy for the prevention of obesity-related metabolic syndromes. PRACTICAL APPLICATIONS: Diosmetin occurs naturally in citrus fruits that have a high inhibitory effect on inflammation in cocultured adipocytes and macrophages via the inactivation of the MAPKs/NF-kB pathway. Diosmetin also inhibited lipolysis via the reduction of FFA and free glycerol. The present study suggests that treatment of diosmetin may be useful for the prevention of obesity and inflammation-related metabolic syndromes.

Effect of calcium chloride and sucrose on the composition of bioactive compounds and antioxidant activities in buckwheat sprouts.

In this study, we evaluated the effect of sucrose and CaCl2 on the growth profile, nutritional quality, and antioxidant capacity of sprouted buckwheat. Buckwheat seeds were germinated at 25 °C for 8 days and sprayed with four different solutions: distilled water, 3% sucrose, 7.5 mM CaCl2, and 3% sucrose plus 7.5 mM CaCl2. Our results showed that CaCl2 effectively improved sucrose-elicitation induced growth reduction in buckwheat sprouts. Elicitation with both sucrose and CaCl2 in buckwheat sprouts markedly enhanced the accumulation of bioactive compounds, such as polyphenols, flavonoids, γ-aminobutyric acid, vitamin C, and E, without negatively affecting sprout growth. Elicitation with both sucrose and CaCl2 not only significantly enhanced the antioxidant activities but also exerted cytoprotective effects against oxidative damage in HepG2 cells and fibroblasts. These findings suggested that simultaneous elicitation with 3% sucrose and 7.5 mM CaCl2 can potentially improve the nutritional value and potential health benefits of buckwheat sprouts.

Jujube (Ziziphus jujuba Mill.) Protects Hepatocytes against Alcohol-Induced Damage through Nrf2 Activation.

This study aimed at evaluating the cytoprotective activity of jujube water extract (JWE) against alcohol-induced oxidative stress via the activation of the Nrf2 pathway in HepG2 cells. JWE had various phenolic compounds, and the vanillic acid content was the highest in the extract. To determine the cytoprotective effect of JWE against alcohol-induced damage, hepatocytes were treated with JWE and 3% ethanol. JWE (100 µg/mL) markedly increased cell viability by approximately 100% in a dose-dependent manner. Moreover, JWE attenuated the production of malondialdehyde, reactive oxygen species, aspartate, and alanine aminotransferase and the depletion of glutathione. Moreover, JWE enhanced the expression of antioxidant defense enzymes including heme oxygenase-1, NADPH quinone oxidoreductase 1, and γ-glutamate-cysteine ligase catalytic against alcohol-induced oxidative damage in hepatocytes via the activation of Nrf2. Taken together, JWE possesses the protective effect against alcohol-induced oxidative injury in hepatocytes through the upregulation of the Nrf2 signaling pathway. Therefore, jujube fruit might have the potential to improve alcohol-related liver problems.

Effects of heat treatment of mandarin peel on flavonoid profiles and lipid accumulation in 3T3-L1 adipocytes.

Citrus peel, a primary byproduct of citrus fruits, contains a variety of flavonoids. Heat treatment is a favorable food processing for solid peel to release bioactive compounds from tissues and intensify nutritional effects. In this study, we explored alterations of flavonoids by thermal treatment of mandarin peel and their effects on lipid accumulation and intracellular levels during differentiation of 3T3-L1 cells to adipocytes. The heat-treated sample showed stronger inhibition on the formation of lipid droplets than the non-treated sample, along with enhanced intracellular levels of flavonoids. Overall flavonoids, especially flavonoid aglycones showing better efficacy, were found to increase in the peel after heat-treatment. Our findings indicate thermal processing could help release flavonoids from citrus peel and convert them into aglycone forms, leading to efficient cellular uptake and suppression of lipid accumulation in 3T3-L1 cells. This study provides useful information of heat-treated citrus peel as potential dietary supplements with anti-obesity-related effects.

Relative protective activities of quercetin, quercetin-3-glucoside, and rutin in alcohol-induced liver injury.

Alcoholic liver diseases has been known to be one of the major health risks worldwide. The purpose of this study was aimed to demonstrate the relative protective effect of quercetin, quercetin-3-glucoside, and rutin on alcohol-induced damage in hepatocytes. The hepatotoxicity, antioxidant enzymatic defense mechanisms, and pro-inflammatory mediators were examined for evaluating the hepatoprotective effects of quercetins in hepG2 cells. The results revealed that quercetin and its glucoside derivatives significantly prevented ethanol-induced hepatotoxicity by decreasing hepatic aminotransferase activities and inflammatory response in HepG2 cells. Moreover, the quercetins significantly induced detoxifying enzymes via the nuclear accumulation of the NF-E2-related factor 2 (Nrf2) and induction of antioxidant response element (ARE) gene. These hepatoprotective activities were observed to be more effective with quercetin aglycone than quercetin glucosides. From the above findings, the present study imply that quercetin aglycone may have a vital function in the therapeutic and preventive strategies of alcoholic liver diseases. PRACTICAL APPLICATIONS: Quercetin is commonly present in fruits and vegetables as aglycone and glucoside-derived forms. In the present study, quercetin and its glycosides was shown to alleviate oxidative stress, glutathione depletion, and pro-inflammatory cytokines in alcohol-induced HepG2 cells via the Nrf2/ARE antioxidant pathway. Moreover, quercetin aglycone had better protective effects against alcohol-induced liver damage in vitro, compared to its glycosylated form. The present study proposed that quercetin aglycone may be a more efficient hepatoprotective agent than its glucoside derivatives such as rutin in the amelioration of alcohol-induced liver diseases.

Conversion of Rutin to Quercetin by Acid Treatment in Relation to Biological Activities.

De-glycosylation could be an important process for enhancing the biological activities of flavonoids. In this study we investigated de-glycosylation of rutin by acid treatment by comparing hydrolysis of rutin to quercetin with two different solvents and acid concentrations. Antioxidant activity was measured using chemical methods and biological activities were examined in cell-based systems. Rutin hydrolysis occurred more rapidly when 80% ethanol was used as the reaction solvent (as compared to water), and the rate of hydrolysis accelerated as acid concentrations increased. In reactions of rutin with 0.5 M HCl in 80% ethanol for 3 h, almost all the rutin was converted into quercetin. 2,2-Diphenyl-1-picrylhydrazyl, 2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid radical scavenging activities, and reducing powers were correlated with conversion rate. Protective activity in HepG2 cells, anti-inflammatory activity in RAW264.7 cells, and antiadipogenic activity were increased with increased conversion of rutin to quercetin. This study suggests that de-glycosylation of glycoside flavonoids may increase physiological activity and, therefore, enhance its use in various fields.

Protective activity of caffeic acid and sinapic acid against UVB-induced photoaging in human fibroblasts.

In this study, the protective effects of caffeic acid (CA) and sinapic acid (SA) on photoaging in human skin fibroblasts induced by UVB irradiation (30 mJ/cm2 ) were examined. The results revealed that exposure to UVB irradiation reduced cell viability by approximately 33% compared with the non-UVB irradiated control. However, CA and SA blocked the UVB irradiation-induced cytotoxicity greater than the other phenolic acids. CA and SA also significantly inhibited the release of matrix metalloproteinase 1 (MMP-1) and reduced the expression of MMP-1 mRNA in UVB-irradiated Hs68 cells. Furthermore, CA and SA reduced UVB-induced production of reactive oxygen species (ROS) and collagen degradation in Hs68 cells. Finally, CA and SA effectively downregulated activation of the UVB-induced mitogen-activated protein kinases (MAPKs) and nuclear factor κB (NFκB) signaling pathways. These results imply that hydroxylated cinnamate derivatives can be therapeutic agents against UVB-induced skin photoaging. PRACTICAL APPLICATIONS: Hydroxylated cinnamate derivatives such as CA and SA have a high cytoprotective effect against UV irradiation-induced photoaging in human fibroblasts via the inactivation of the MAPKs/NFκB signaling pathway. The present study suggests that CA and SA may be useful in therapeutic and cosmetic applications for the treatment of skin photoaging.

Protective Effects of Unsaponifiable Matter from Perilla Seed Meal on UVB-induced Damages and the Underlying Mechanisms in Human Skin Fibroblasts.

Unsaponifiable matter (USM) from perilla seed meal contains numerous phytochemicals, including tocopherols, phytosterols, squalene, and policosanols, that exhibit antioxidant and health-promoting properties. In this study, the protective effects of USM on UVB-induced skin aging were investigated in Hs68 cells. UVB irradiation decreased cell viability by 26% compared to the control. However, USM blocked UVB-induced cytotoxicity. Moreover, USM treatment significantly decreased the UVB-induced production of reactive oxygen species and attenuated the UVB-induced production and mRNA expression of matrix metalloproteinases (MMPs) by inhibiting the phosphorylation of mitogen-activated protein kinases and activator protein 1 (AP-1). Furthermore, UVB exposure led to a 49.4% reduction in collagen synthesis. However, USM treatment restored collagen synthesis through upregulation of the transforming growth factor beta (TGF-ß)/Smad2/3 pathways. These data indicate that USM regulates the production of MMPs and collagen by modulation of the TGF-ß/Smad pathway and AP-1 activity, suggesting that USM may be a useful anti-photoaging ingredient.

Relationship between Sensory Attributes and Chemical Composition of Different Mango Cultivars.

The present study investigated the relationship between the chemical composition and sensory quality of different mango ( Mangifera indica L.) cultivars by multivariate statistical analysis. The results showed that the high hedonic rating of mangoes was due in part to its flavor profile such as fruity, pineapple, and coconut with sweetness. High hedonic liking and positive flavors of mangoes could be responsible for the volatile compounds including fruity esters, 1-octanol, ( E, Z)-2,6-nonadienal, and γ-octalactone with high contents of sugars. On the other hand, turpentine-like and green flavors of mangoes are attributed to the relatively low hedonic liking of mangoes, which correlated with high contents of amino acids and terpenes. These findings demonstrated that interaction between individual chemical compounds within mangoes could be responsible for the specific sensory qualities of mango cultivars and provided insight into a paradigm for the selection and development of new and more desirable mango cultivars in the future.
