Abstract
Tuber and tuberous roots proteins are important sources for producing bioactive peptides. The objective of this review is to present the current research status of tubers and tuberous roots bioactive peptides (TTRBP), including its preparation methods, purification techniques, structure identification approaches, biological functions, and applications in the food industry. Moreover, the current challenges and future development trends of TTRBP are elucidated. Currently, TTRBP are mainly produced by enzymatic hydrolysis and fermentation. Pretreatment like high static pressure, ultrasound and microwave can assist enzymatic hydrolysis and facilitate TTRBP production. In addition, TTRBP are structurally diverse, which is related to the molecular weight, amino acids composition, and linkage mode. Accordingly, they have various biological activities (such as antioxidant, antihypertensive, hypoglycemic) and have been utilized in the food industry as functional ingredients and food additives. This review will provide valuable insights for the optimal utilization of tuber and tuberous roots.

JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2024; 104:6342-6349. [PMID: 38415792 DOI: 10.1002/jsfa.13418] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Revised: 01/29/2024] [Accepted: 02/25/2024] [Indexed: 02/29/2024]
Abstract
BACKGROUND Dioscorea opposita Thunb. cv. Tiegun maturity (DM) is an important factor influencing its quality. However, there are few studies on the impact of harvest time on its maturation. In the present study, a NMR-based metabolomics approach was applied to investigate the dynamic metabolic changes of D. opposita Thunb. cv. Tiegun at six different harvest stages: stage 1 (S1), stage 2 (S2), Stage 3 (S3), stage 4 (S4), stage 5 (S5) and stage 6 (S6). RESULTS Principal component analysis showed distinct segregation of samples obtained from S1, S2 and S3 compared to those derived from S4, S5 and S6. Interestingly, these samples from the two periods were obtained before and after frost, indicating that frost descent might be important for DM. Eight differential metabolites responsible for good separation of different groups were identified by the principal component analysis loading plot and partial least squares-discriminant analysis. In addition, quantitative analysis of these metabolites using liquid chromatography-tandem mass spectrometry determined the effects of harvest time on these metabolite contents, two of which, sucrose and allantoin, were considered as potential biomarkers to determine DM. CONCLUSION The present study demonstrated that NMR-based metabolomics approach could serve as a powerful tool to identify differential metabolites during harvesting processes, also offering a fresh insight into understanding the DM and the potential mechanism of quality formation. © 2024 Society of Chemical Industry.

A Comparative Analysis between Whole Chinese Yam and Peeled Chinese Yam: Their Hypolipidemic Effects via Modulation of Gut Microbiome in High-Fat Diet-Fed Mice. Nutrients 2024; 16:977. [PMID: 38613011 PMCID: PMC11013417 DOI: 10.3390/nu16070977] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2024] [Revised: 03/25/2024] [Accepted: 03/25/2024] [Indexed: 04/14/2024] Open
Abstract
Chinese yam is a "medicine food homology" food with medical properties, but little is known about its health benefits on hyperlipidemia. Furthermore, the effect of peeling processing on the efficacy of Chinese yam is still unclear. In this study, the improvement effects of whole Chinese yam (WY) and peeled Chinese yam (PY) on high-fat-diet (HFD)-induced hyperlipidemic mice were explored by evaluating the changes in physiological, biochemical, and histological parameters, and their modulatory effects on gut microbiota were further illustrated. The results show that both WY and PY could significantly attenuate the HFD-induced obesity phenotype, accompanied by the mitigative effect on epididymis adipose damage and hepatic tissue injury. Except for the ameliorative effect on TG, PY retained the beneficial effects of WY on hyperlipemia. Furthermore, 16S rRNA sequencing revealed that WY and PY reshaped the gut microbiota composition, especially the bloom of several beneficial bacterial strains (Akkermansia, Bifidobacterium, and Faecalibaculum) and the reduction in some HFD-dependent taxa (Mucispirillum, Coriobacteriaceae_UCG-002, and Candidatus_Saccharimonas). PICRUSt analysis showed that WY and PY could significantly regulate lipid transport and metabolism-related pathways. These findings suggest that Chinese yam can alleviate hyperlipidemia via the modulation of the gut microbiome, and peeling treatment had less of an effect on the lipid-lowering efficacy of yam.

Abstract
Bulbil of yam (BY) extract contains various active compounds possessing many pharmacological properties. However, little is known about the effect and underlying mechanism of BY extract on ethanol-induced liver damage. The present study explored the beneficial potential of BY extract on ethanol-induced hepatotoxicity. To evaluate its effectiveness, ethanol-induced HepG2 liver cells were pretreated with BY extract. BY extract effectively rescued cells from ethanol treatment through inhibition of apoptotic cell death as well as inhibiting expression of mitogen-activated protein kinase (MAPK) proteins as stress inducers. BY extract increased the expression of typical antioxidants. Furthermore, BY extract significantly inhibited mitochondrial dysfunction and endoplasmic reticulum (ER) stress, which are major ROS-inducing factors. Finally, as an underlying mechanism of the protective effects of BY extract on ethanol-induced liver damage, it activated Nrf2 protein through translocation from the cytosol to the nucleus, which in turn activated its target oxidative stress suppressor genes. Collectively, our findings demonstrate that BY extract has potential antioxidative effects in ethanol-induced liver cells and contributes to the establishment of a treatment strategy for alcohol-derived liver injuries.

Abstract
Chinese yam (Dioscorea polystachya Turczaninow) by-product produced in the water extraction process is commonly directly discarded resulting in a waste of resources and environmental pollution. However, the value of Chinese yam by-product which still contains effective ingredients is far from being fully realized; hence, it has the potential to be a safe and effective feed additive in aquaculture. To investigate the impacts of Chinese yam by-product on growth performance, antioxidant ability, histomorphology, and intestinal microbiota of Micropterus salmoides, juvenile fish (initial weight 13.16 ± 0.05 g) were fed diets supplemented with 0% (control), 0.1% (S1), 0.4% (S2), and 1.6% (S3) of Chinese yam by-product for 60 days. The results showed that no significant difference was found in weight gain, specific growth rate, and survival among all the experimental groups (P > 0.05). Feed conversion ratios of the S1 and S3 groups were significantly lower than those in the control group (P < 0.05). SOD activity of the S3 group and GSH contents of Chinese yam by-product groups were significantly higher than those in the control group (P < 0.05). MDA levels of the S2 and S3 groups were significantly lower than those in the control group and the S1 group (P < 0.05). Besides, Chinese yam by-product could protect liver and intestine health, as well as increase the abundance of beneficial bacteria and decrease the abundance of potential pathogens. This study suggests that Chinese yam by-product has the potential to be used as a functional feed additive in aquaculture, providing a reference for efficient recovery and utilization of by-products from plant sources during processing and culturing high-quality aquatic products.

Effects of Dietary Supplementation of Chinese Yam Polysaccharide on Carcass Composition, Meat Quality, and Antioxidant Capacity in Broilers. Animals (Basel) 2023; 13:ani13030503. [PMID: 36766389 PMCID: PMC9913201 DOI: 10.3390/ani13030503] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2023] [Revised: 01/28/2023] [Accepted: 01/30/2023] [Indexed: 02/05/2023] Open
Abstract
The study aimed to evaluate the influences of the dietary supplementation of Chinese yam polysaccharide (CYP) on the carcass performance, antioxidant capacity, and meat quality of broilers. Three hundred and sixty healthy 1-day-old broilers with similar body weight (39 ± 1 g, gender balanced) were randomly divided into four groups (control, CYP1, CYP2, and CYP3 groups). In the control group, broilers were fed a basal diet with CYP, and the CYP1, CYP2, and CYP3 groups were fed diets supplemented with 250, 500, and 1000 mg/kg CYP, respectively. There were three replicates in each group, 30 birds in each replicate, and the feeding trial lasted for 48 days. Statistical analysis was performed using SPSS 17.0 (SPSS Inc., Chicago, IL, USA) by one-way analysis of variance. The results showed that compared with the control group, dietary supplementation with 500 mg/kg CYP can improve live weight, half-eviscerated carcass percentage, eviscerated carcass percentage, and thigh muscle percentage. Moreover, dietary supplementation with 500 mg/kg CYP can improve the contents of total antioxidant capacity (T-AOC), total superoxide dismutase (T-SOD), glutathione peroxidase (GPX), and glutathione s-transferase (GST) in serum (p < 0.05). Meanwhile, the mRNA expression levels of nuclear factor-erythroid 2-related factor 2 (Nrf2), heme oxygenase 1 (HO-1), quinone oxidoreductase (NQO1), superoxide dismutase 1 (SOD1), glutathione peroxidase 1 (GPX1), and catalase (CAT) in the liver; the mRNA expression levels of HO-1, NQO1, GPX1, and CAT in the breast muscle; and the mRNA expression levels of NQO1, SOD1, and CAT in the thigh muscle of broilers in the CYP2 group were significantly increased (p < 0.05). In addition, the yellowness and shear force of the thigh and breast muscles and the content of malondialdehyde (MDA) in the serum of broilers in the control group were higher than that in the CYP2 groups (p < 0.05). The results demonstrated that the CYP2 group had the best effect on improving meat quality. In conclusion, dietary supplementation with 500 mg/kg CYP can improve the meat quality of broilers by improving carcass quality, meat color, shear force, and antioxidant capacity.

Effects of Chinese yam Polysaccharides on the Muscle Tissues Development-Related Genes Expression in Breast and Thigh Muscle of Broilers. Genes (Basel) 2022; 14:genes14010006. [PMID: 36672746 PMCID: PMC9858316 DOI: 10.3390/genes14010006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2022] [Revised: 12/16/2022] [Accepted: 12/19/2022] [Indexed: 12/24/2022] Open
Abstract
This experiment was conducted to evaluate the effects of dietary Chinese yam polysaccharides (CYP) on myogenic differentiation 1 (MYOD1), myogenin (MYOG), and myostatin (MSTN) mRNA expression of breast and thigh muscle tissues in broilers. A total of 360 (1-day-old, gender-balanced) crossbred broilers chicks with similar body weight (BW) were randomly distributed into four groups, with three replicates in each group and each replicate included 30 broilers. The feeding trial lasted for 48 days. Experimental broilers were fed 0.00 mg/kg basal diet (control group), 250 mg/kg, 500 mg/kg, and 1000 mg/kg CYP, respectively. The results showed that CYP250 and CYP500 groups had higher thigh muscle percentage (TMP) compared to the control group (p < 0.05). Meanwhile, the expression of MYOD1, MYOG mRNA in breast muscle tissues of CYP500 and CYP1000 groups was higher (p < 0.05), and the expression of MSTN mRNA in thigh muscle of CYP250, CYP500, and CYP1000 groups was lower than that of the control group (p < 0.05). In addition, there was no significant difference in the expression of MYOD1 mRNA in the thigh muscle tissue of each group (p > 0.05). Bivariate correlation analysis showed that the expression levels of MYOD1, MYOG, and MSTN mRNA in the thigh muscle tissue of broiler chickens in the CYP500 group were positively correlated with TMP. However, the expression of MYOG mRNA in thigh muscle tissue of the CYP1000 group was negatively correlated with TMP. In general, this study indicated that appropriate dietary CYP supplementation influenced the growth and development of thigh muscle tissue in broilers by altering TMP and muscle tissue development-related genes expression. Therefore, CYP could be used as a potential feed additive to promote the development of muscle tissues in broilers.

Abstract
The purpose of this experiment was to investigate the effects of Chinese yam polysaccharides (CYP) in diets on the immune function of broilers. A total of 360 (1-day-old, sex balance) healthy growing broilers with similar body weight (39.54 ± 0.51 g) were randomly divided into control (0.00 g/kg), CYP I (0.25 g/kg), CYP II (0.50 g/kg), and CYP III (1.00 g/kg) groups. Each group contains 3 replicates with 30 broilers in each replicate, and the feeding trial lasted 48 d. The results showed that compared with the control group, the CYP II group had higher thymus index, serum IgA, complement C3, C4, IGF-I, T3, T4, INS, GH, IL-2, IL-4, IL-6, and TNF-α levels (P < 0.05) at 28, 48 d, respectively. In addition, the spleen index, serum IgM and IgG concentrations in CYP II group were higher than those in the control group at 28 d (P < 0.05). Results indicated that 0.50 g/kg CYP supplementation improved the immune function of broilers, and the CYP has a potential biological function as a green additive in broilers.

MOLECULES (BASEL, SWITZERLAND) 2022; 27:molecules27082530. [PMID: 35458730 PMCID: PMC9026138 DOI: 10.3390/molecules27082530] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/01/2022] [Revised: 03/25/2022] [Accepted: 04/08/2022] [Indexed: 12/23/2022]
Abstract
Dioscorea, consisting of over 600 species, is the most important genus in the Dioscoreaceae family; however, the practically used plants, which are commonly called yam, are restricted to a remarkably smaller number of species. Numerous studies have reported the high nutritional value of yam, particularly as an alternative source of starch and some important micronutrients. Several Dioscorea species are widely used for various medicinal purposes as well. In many studies, the bioactivities and health benefits of Dioscorea extracts and other preparations have been related to the presence of phytochemicals, which possess antioxidant properties; they are related mainly to radical-scavenging capacity in chemical assays and positive effects on the endogenous antioxidant system in cell-based and in vivo assays. Considering the increasing number of publications on this topic and the absence of comprehensive and focused review papers on antioxidant potential, this article summarizes the results of studies on the antioxidant properties of Dioscorea spp. and their relation to phytochemicals and health benefits. A comprehensive survey of the published articles has revealed that the majority of studies have been performed with plant tubers (rhizomes, roots), while reports on leaves are rather scarce. In general, leaf extracts demonstrated stronger antioxidant potential than tuber preparations. This may be related to the differences in phytochemical composition: saponins, phenanthrenes and, for some pigment-rich species (purple yams), anthocyanins are important constituents in tubers, while phenolic acids and flavonoids are characteristic phytochemicals in the leaves. The review may assist in explaining ethnopharmacological knowledge on the health benefits of Dioscorea plants and their preparations; moreover, it may foster further studies of poorly investigated species, as well as their wider application in developing new functional foods and nutraceuticals.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The two major theories utilized for diagnosis and treatment in Traditional Thai Medicine (TTM) are the Four Element Theory and the Herbal Flavor Theory. A TTM "Poh-Pu" Remedy has been effectively utilized in Thailand for cancer therapy for centuries. AIMS OF STUDY To investigate anti-inflammatory activity and liver cancer cytotoxicity of Poh-Pu remedy. To determine relationships between the TTM Herbal Flavor theory and the Four Element theory and total flavonoid content and biological activities of Poh-Pu Remedy plant extracts. MATERIALS AND METHODS Each plant ingredient was macerated with 95% ethanol. The extracts were investigated for cytotoxic activity against liver cancer using a sulforhodamine B assay, and anti-inflammatory activity was evaluated by inhibition of nitric oxide production. The total flavonoid content was determined by an aluminum chloride colorimetric assay. The relationships between the TTM theories, total flavonoid content, and biological activities were evaluated by correlation and cluster analysis. RESULTS Mammea siamensis exerted potent cytotoxicity against hepatocellular carcinoma (HepG2) cell lines with an IC50 of 3.15 ± 0.16 μg/mL and low cytotoxicity to the non-cancerous cells (HaCat) with an IC50 33.39 ± 0.40 μg/mL (Selective index (SI) = 10.6). Tiliacora triandra was selectively cytotoxic to cholangiocarcinama (KKU-M156) cells with an IC50 of 12.65 ± 0.92 μg/mL (SI = 6.4). Curcuma comosa was the most potent anti-inflammatory inhibitor of nitric oxide production with an IC50 of 2.75 ± 0.34 μg/mL. Campomanesia aromatica exhibited the highest total flavonoid content of 259.7 ± 3.21 mg quercetin equivalent/g. Pungent plants were most prevalent in the TTM remedy. CONCLUSION Pungent, fragrant, bitter and nauseating plants utilized in TTM cancer remedy were successfully investigated and identified several lead plants and components with cytotoxic and antiinflammatory activity that require further study. The TTM wind element theory appeared to be aligned with cancer-related activity. Biological activity results of taste from herbs related with The TTM Herbal Flavor theory. The extra-oral locations of flavor receptors are a promising target for biological activity of TTM which require further scrutiny and identified several lead plants and components with cytotoxic and antiinflammatory activities that also require further study.

Abstract
The aim of this study was to investigate the anti-fatigue activity of Chinese Yam polysaccharides (CYPs). The structural characterization of CYPs was conducted using Fourier transform-infrared spectroscopy, nuclear magnetic resonance spectroscopy, gel permeation chromatography-light scattering-refractive index, and ion chromatography. The weight-loaded swimming capability, behavior performance, tumor growth, content of adenosine triphosphate (ATP), and biochemical markers of CYP in a cancer-related fatigue mouse model were tested. The results showed that CYP is a mixture with an average Mw of 75.57 kDa and is mainly composed of rhamnose, glucuronic acid, glucose, galactose, and arabinose with a molar ratio of 0.01 : 0.06 : 1.00 : 0.17 : 0.01. CYP increased the exhausting swimming time, which was decreased in the cisplatin (DDP) control group and the model group. CYP also increased the content of ATP in musculus gastrocnemius, which was down-regulated by DDP; the DDP had significantly enhanced the contents of interleukin-1β (IL-lβ), malondialdehyde (MDA), blood urea nitrogen (BUN) and lactic dehydrogenase (LDH) and inhibited the activity of superoxide dismutase (SOD) in the muscle. Administration of CYP decreased the levels of IL-lβ, MDA, BUN and LDH, and up-regulated the SOD activity. The DDP + CYP group presented a decreased tumor volume and a lower tumor weight as compared with the model group. Moreover, the mice in the CYP or DDP + CYP groups had heavier body weights than the mice in the model group and DDP group. These results suggest that CYP should improve cancer-related fatigue via the regulation of inflammatory responses, oxidative stress and increase in energy supplementation.

Abstract
Royal jelly (RJ) and selenium (Se)-rich foods have well-known health benefits that are attributable to a broad range of pharmacological effects including antioxidant, anti-tumor, and immunoregulatory activities. However, the physiological effects of Se-rich RJ, which is produced by feeding Apis mellifera (Hymenoptera: Apidae) sodium selenite sucrose solution, are not well understood. The anti-hepatoma activity and mechanism of Se-rich RJ in H22 tumor-bearing mice were investigated in the current study. The findings showed that the content of organic and inorganic Se in Se-rich RJ was significantly higher than that in RJ. Furthermore, interleukin-2 (IL-2) levels and tumor necrosis factor-α (TNF-α) production in serum were increased and the malondialdehyde (MDA) content in liver was decreased in mice fed RJ and Se-rich RJ. 16SrRNA sequencing and serum untargeted metabolomics showed that RJ and Se-rich RJ could modulate the gut microbiota, and fisetin and l-glutathione oxidized were the main anti-tumor components in RJ and Se-rich RJ. Further analysis showed 11-deoxy prostaglandin F1β was the specific anti-tumor metabolite in mice treated with Se-rich RJ compared with RJ. The results indicated that RJ and Se-rich RJ could inhibit the expression of PI3K and phosphorylation of AKT, induce cell apoptosis through the activation of caspase-9 and caspase-3, and regulate Bcl-2/Bax expression. RJ and Se-rich RJ also inhibited the expression of COX-2 and VEGF. To summarize, the findings clearly demonstrate that Se-rich RJ could inhibit tumor growth by inducing apoptosis and inhibiting angiogenesis as well as exhibit anti-tumor effects by improving immune function and antioxidant activities. The results indicated that Se-rich RJ could be a potential functional food for the management and prevention of cancer.

Abstract
Yam (Dioscorea opposite Thunb) is used as a staple food and a traditional medicine in China. This study investigated the effects of different household cooking methods on the bioactive components (phenolic compounds, diosgenin and allantoin) and their bioaccessibility as well as the biological properties (antioxidant activity, hypoglycemic activity, anti-angiotensin I-converting enzyme (ACE) or anti-acetylcholinesterase (AChE)) of Chinese yam using an in vitro simulated digestion model. The results demonstrated that cooking caused significant losses of total soluble phenolic compounds (lowest loss of 20% for boiling at atmospheric pressure) and diosgenin content (lowest loss of 27.37% for microwaving) but no changes in the allantoin content. The cooking methods affected the bioaccessibility of the bioactive components differently. Normal steaming resulted in the highest amount of bioaccessible phenolic compounds (71.21%) and allantoin (79.07%), whereas high-pressure boiling in the highest content of diosgenin (75.58%). The concentration of bioactive components in the digesta fluid was correlated with the antioxidant activity and enzymatic inhibitory activities. Overall, household cooking processes allow the biological activity of yam to be retained by changing the profile of bioactive components potentially available for intestinal absorption. Thus, a household cooking method such as normal pressure steaming appeared to be most suitable for achieving the expected health benefits of yam.

Abstract
In this study, we evaluated the protective effect and molecular mechanism of a dominant phenanthrene, (6,7-dihydroxy-2,4-dimethoxyphenanthrene, CYP4), from Chinese yam peels on intestinal epithelial integrity. Three doses of Chinese yam phenolic extract (CYPE) and Chinese yam phenanthrene 4 (CYP4) were administered to BALB/c mice for 7 days before dextran sulfate sodium (DSS) treatment, with berberine hydrochloride as a positive control (PC). Results showed that both disease activity indexes (DAIs), histological damage score (HDS) and survival rate in DSS mice, were improved with preintervention of CYPE and CYP4, which exhibited better efficiency than PC. Further studies showed that administration of CYP4 downregulated the oxidative stress-associated factors, MPO and NO, and improved tight junction protein occludin. Besides, the CYP4 treatment substantially downregulated the caspase-3 expression and the apoptosis rate of intestinal epithelial cells. In addition, the CYP4 treatment ameliorated the production of inflammatory cytokines including TNF-α, IFN-γ, IL-10, and IL-23 in the colon. Furthermore, the protein expression of ERK1/2, NF-κB p65, pNF-κB, and COX-2 was suppressed in CYE4 groups as compared with that in model control (MC). These findings suggested that CHP4 could effectively inhibit the activation of NF-κB/COX-2 in an experimental UC model in vivo. It was demonstrated for the first time that CYPE and CYP4 protected intestinal mucosa from damage and prevented DSS-induced colitis in mice. CYP4 was one of the active principles obligatory for the biological effect of Chinese yam in protecting intestinal health. These findings indicated that CYP4 might be a promising and useful approach for treatment of UC in humans.

Abstract
Abstract
Background
The monocotyledonous herbaceous crop Dioscorea is native to tropical and temperate regions of the world. Dioscorea tubers are dioecious in nature, have colossal therapeutic potentiality, and are frequently used in traditional medical practices throughout the world. Most of the research works are aimed to determine the medicinal property, nutritions, antinutrients, and biological activities of Dioscorea spp. without specifying the sexes of Dioscorea which promoted us to carry out this present research work.
Results
Sex-specific variation of phytoconstituents, antioxidants, and antimicrobial efficiency in tubers was appraised. The results obtained from this study divulge existence of significant quantitative variation between the male and female tubers. The female tubers are superior in acquiring phytochemicals compared to male counterparts and acquired maximum antioxidant and antimicrobial potentiality.
Conclusion
This study will offer an apposite baseline for further sex-specific assessment which can be directed towards both qualitative and quantitative amelioration of medicinally important noble compounds by exploiting modern scientific strategies leading to their active participation in nutraceutical industries.

Abstract
MAIN CONCLUSION The diversification of food crops can improve our diets and address the effects of climate change, and in this context the orphan crop Chinese yam shows significant potential as a functional food. As the effects of climate change become increasingly visible even in temperate regions, there is an urgent need to diversify our crops in order to address hunger and malnutrition. This has led to the re-evaluation of neglected species such as Chinese yam (Dioscorea polystachya Turcz.), which has been cultivated for centuries in East Asia as a food crop and as a widely-used ingredient in traditional Chinese medicine. The tubers are rich in nutrients, but also contain bioactive metabolites such as resistant starches, steroidal sapogenins (like diosgenin), the storage protein dioscorin, and mucilage polysaccharides. These health-promoting products can help to prevent cardiovascular disease, diabetes, and disorders of the gut microbiome. Whereas most edible yams are tropical species, Chinese yam could be cultivated widely in Europe and other temperate regions to take advantage of its nutritional and bioactive properties. However, this is a laborious process and agronomic knowledge is fragmented. The underground tubers contain most of the starch, but are vulnerable to breaking and thus difficult to harvest. Breeding to improve tuber shape is complex given the dioecious nature of the species, the mostly vegetative reproduction via bulbils, and the presence of more than 100 chromosomes. Protocols have yet to be established for in vitro cultivation and genetic transformation, which limits the scope of research. This article summarizes the sparse research landscape and evaluates the nutritional and medical applications of Chinese yam. By highlighting the potential of Chinese yam tubers, we aim to encourage the adoption of this orphan crop as a novel functional food.

Abstract
Over the past two decades, many studies have shown that the yam storage protein dioscorin, which is abundant in the wastewater of starch processing, exhibits many biological activities both in vitro and in vivo. In the present study, the acid-precipitation method was optimized using Box-Behnken design (BBD) combined with response surface methodology (RSM) for the recovery of yam soluble protein (YSP) from wastewater. The experimental yield of YSP reached 57.7%. According to relative quantitative proteomics (LC-MS/MS), the crude YSP was mainly composed of 15 dioscorin isoforms, which was further verified by anion-exchange and size-exclusion chromatography. YSP was found to be rich in glutamic acid and aspartic acid, and the eight essential acids made up approximately 33.7% of the YSP. Moreover, the YSP demonstrated antioxidant activity, including scavenging DPPH, hydroxyl and superoxide anion radicals, and the possible structure-activity relationships were discussed. These results indicated that YSP produced by acid precipitation may be used as a protein source with antioxidant properties.

Abstract
Background:
The total antioxidant capacity of yam food grown in southern African regions
was investigated by a polyglycine-glassy carbon modified electrode. The modified electrode was fabricated
using glycine solution on glassy carbon electrode by electrodeposition method. The proposed
modified electrode is found to be nearly 3.15-fold more sensitive than the bare electrode. For the
measurement of the total antioxidants of yam, differential pulse stripping voltammetry (DPSV) was
employed with standard quercetin compound.
Methods:
The total antioxidant capacity of yam was deduced by DPSV and cyclic voltammetry (CV)
methods. The basic parameters for the stripping technique such as pH, accumulation time and accumulation
potential were optimized as 20 s, 200 mV and a pH of 3 Britton-Robinson (B-R) buffer solutions
in 0.5 mg quercetin/L, respectively.
Results:
In the optimization condition, the linear working range was determined between 5.0 μg/L and
80.0 µg/L for the quercetin. The detection (LOD) and quantification (LOQ) limits of quercetin were
found to be 0.39 µg/L and 1.39 µg/L on the modified electrode by DPSV, respectively. The procedure
was also applied to natural yam samples and total antioxidant capacity of 0.1 kg of yam was determined
as 96.15 ± 0.85 µg/L of equivalent quercetin at 95% confidence level with the relative standard
deviations of 0.88%.
Conclusion:
Sensitive and selective voltammetric method was developed for the determination of total
antioxidant capacity in yam. Moreover, the modified polyglycine-glassy carbon electrode was constructed
more selectively for quercetin. As a result, a simple, sensitive and rapid new voltammetric
method for the determination of antioxidants has been developed using the modified electrode.

Abstract
Objective: Antibiotics have saved hundreds of millions of patient's lives, but there are also many side effects. This paper mainly studies the regulation of Chinese yam on antibiotic-induced gut dysbiosis in rats. Methods: Male Wistar rats were divided into three groups, normal control group, antibiotic group, and Chinese yam group. In the antibiotic group and the yam group, a rat model of intestinal dysfunction was established by intragastric administration of imipenem/cilastatin sodium (antibiotic) for 21 days. The yam group was also given yam decoction for intervention. The fecal samples of each group of rats were analyzed using an ultra-performance liquid chromatography quadrupole/time-of-flight mass spectrometry (UPLC-Q-TOF/MS) method to find potential biomarkers. The DNA in the feces was extracted, and analyzed using 16S rDNA method to find the differential flora. Spearman correlation analysis was performed on differential flora and differential metabolites to determine the main metabolic pathways of the host after intestinal flora dysregulation. Results: The administration of antibiotics can lead to disorders of intestinal flora, decreased microbial diversity, and changes in host metabolic phenotype. Chinese yam can significantly improve the intestinal flora, making the host's metabolic phenotype tend toward normal. Conclusion: Long-term use of Imipenem/cilastatin sodium can cause disturbance of intestinal flora in normal rats. Chinese yam may regulate intestinal flora disorder and have potential prebiotic effects.

Abstract
Vascular endothelial growth factor receptor-2 (VEGFR-2) regulates the mitogen-activated protein kinase (MAPK) signaling pathway and plays an important role in angiogenesis. Bu Shen Zhu Yun decoction (BSZYD) can improve endometrial receptivity and embryo implantation rates in patients undergoing in vitro fertilization. However, whether BSZYD improves endometrial receptivity via angiogenesis remains unclear. Here, we investigated the effects of BSZYD on the proliferation, migration, and angiogenesis of human endometrial microvascular endothelial cells (HEMECs) and found that BSZYD upregulated the expression of cyclin D1, matrix metalloproteinase 9 (MMP9), and proliferating cell nuclear antigen (PCNA) in HEMECs. Cell Counting Kit 8 assay, scratch-wound assay, and Tube Formation Assay results showed that BSZYD promoted the proliferation, migration, and angiogenesis of HEMECs. Western blot analysis results revealed the activation of the MAPK signaling pathway by BSZYD through the upregulation of VEGF and VEGFR-2 expression. Together, these findings highlight the novel mechanism underlying BSZYD-mediated improvement in endometrial receptivity through the MAPK signaling pathway.

Abstract
The Chinese yam peel (CYP) is a by-product of yam processing that is rich in various nutrients and a good source for feed additives. This study investigated the effects of CYP on the intestinal microbiota and gut defence barrier of the common carp (Cyprinus carpio L.). Different groups of experimental fish were fed a normal control diet (NC), a low CYP diet (LYP) and a high CYP diet (HYP) for 8 weeks. After the feeding trial, the fish were assessed for intestinal enzyme activity, intestinal histology, immune-related gene expression, intestinal SCFAs and intestinal microbiota. Our results indicated that the intestinal integrity and antioxidant enzyme (CAT and SOD) activity in the common carp were enhanced following CYP supplementation. The mRNA levels of anti-inflammatory (TGF-β), tight binding protein (occludin and ZO-1) and pathway factor genes (TLR4 and NF-κB) were significantly upregulated in the HYP group (P<0.05), which was accompanied by an increase in the level of pro-inflammatory IL-1β in the gut (P<0.05). High-throughput sequencing revealed that Fusobacteria, Proteobacteria, and Bacteroidetes bacteria were most abundant in the microbial community in the gut of the common carp. The relative abundances of Bacteroides, Flavobacterium and Lactobacillus were increased, while the abundances of pathogenic microorganisms such as Enterobacteriaceae, Shewanella, Pseudomonas and Vibrio were reduced after treatment with CYP. Furthermore, the concentrations of acetic acid, propionic acid, butyric acid and total short-chain fatty acids (SCFAs) in the gut were also increased (P<0.05). Finally, our results revealed correlations between gut microbiota, SCFAs, non-specific immunity and antioxidant enzymes in CYP-fed carp. These results suggest that CYP-supplemented feed could improve the immunity of the common carp by modulating the intestinal microflora and enhancing the gut defence barrier and has the potential to be used as an immunostimulating feed additive in aquaculture.

Abstract
Dioscorea batatas Decne (Chinese yam) has been widely cultivated in East Asia for the purposes of food and medicinal uses for centuries. Along with its high nutritional value, the medicinal value of D. batatas has been extensively investigated in association with phytochemicals such as allantoin, flavonoids, saponins and phenanthrenes. Phenanthrenes are especially considered the standard marker chemicals of the Chinese yam for their potent bioactivity and availability of analysis with conventional high performance liquid chromatography with ultraviolet detection (HPLC-UV) methods. In order to investigate how much the contents of phenanthrenes are in the actual food products provided for consumers, D. batatas tuber was peeled and separated into its peel and flesh as in the conventional processing method. A quantitative analysis using the HPLC-UV method revealed that phenanthrenes are concentrically present in the D. batatas peel, while phenanthrenes are present in the flesh under the limit of detection. The difference in the contents of phenanthrenes is estimated to have arisen the considerable difference of antioxidant potential between the peel and the flesh. The results from this study suggest the high value of the discarded biomass of the Chinese yam peel and the necessity for the utilization of the Chinese yam peel.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Zuogui Pills (ZGP), which is a classical prescription of Traditional Chinese Medicine (TCM), has been reported to be widely used in the treatment of premature ovarian failure (POF). AIM OF THE STUDY To investigate the therapeutic effects of ZGP on the treatment of POF induced by chemotherapy, and elucidate the potential molecular mechanism. MATERIALS AND METHODS Female 8-week-old Sprague-Dawley rats (N = 54) were randomized to six groups, containing the Control group, Model group, three ZGP groups and Triptorelin group which was served as a positive control. The Triptorelin group received triptorelin injection ten days before model establishment by cyclophosphamide. The three ZGP groups (high dose group, medium dose group and low dose group) were given a daily intragastric administration of ZGP at doses of 3.2, 1.6 and 0.8 g/kg for sixty days. We observed the general growth of rats and examed the estrous cycle and the rate of pregnancy, ovarian ultrastructures, follicles and corpora lutea numbers. The serum hormone concentrations were measured by Enzyme-linked immunosorbent assay (ELISA). To explore the molecular mechanism of the effect, gene and protein expression levels of Bax, Bcl-2 and Cyt-c related to apoptosis were determined by quantitative PCR (qPCR), Western Blot and Immunohistochemistry analysis, respectively. RESULTS After treating with ZGP, though the rate of pregnancy showed no significant difference, the estrous cycle, ovarian ultrastructures, numbers of follicles and corpora lutea were improved significantly. And ZGP led to a significant lower concentration of follicle stimulating hormone (FSH) in the serum, and the concentration of oestradiol (E2) was increased. Furthermore, a significant downregulation of Bax, cytochrome c (Cyt-c), and upregulation of B cell lymphoma/leukemia-2 (Bcl-2) both on gene and protein levels were observed after the administration with ZGP. And effects showed a positive correlation with the dosages. CONCLUSIONS Our study suggested that ZGP exerted significant effect on POF, which was meditated by inhibiting mitochondria-dependent apoptosis in the follicles.

[PMID: 33381290 PMCID: PMC7753890 DOI: 10.5897/jen2018.0222] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2018] [Accepted: 01/24/2019] [Indexed: 11/23/2022]
Abstract
Pests and diseases infested material of seed yams have led to sub optimal yield
levels. Neem was applied as substitute for chemical pesticides and as
environmentally safe bio-pesticide to reduce the crops annual loss due to
herbivore pests and their resulting diseases. Field trials were conducted during
the 2016 and 2017 major planting seasons in four communities each of
Ejura-Sekyedumase and Atebubu-Amantin districts of the Ashanti and Brong Ahafo
regions respectively. Yam minisetts sizes were pre-treated with Mancozeb at a
rate of 100 g and Lambda cyhalothrin at 40 ml in 10 L water as cocktail. Yam
minisetts of 30 g each were planted on ridges at 100 cm between and 30 cm within
rows on a 20 m × 20 m plot size. Neem leaf powder was applied on five
rows per plot and another five served as check for assessment. Harvesting was
done approximately 6 to 7 months after planting. Scale insects, mealybugs,
beetles, termites and millipedes infestations. Galling due to root-knot
nematodes, cracks, soft and wet rot were assessed on a scale of 1-5. Tuber
yields were also assessed. Neem treated plots were observed to have
significantly reduced arthropod pest populations and nematode galling as well as
damage signs compared to the control plots. Yields of seed yam were higher on
the neem treated plots than the control, probably due to the reduced damage on
the treated plots. Seed yam yield increased for plots treated with
Azadirachta indica leaves by 40 and 41% at
Ejura-Sekyedumase district as well as 45 and 20% at Atebubu-Amantin district for
2016 and 2017 respectfully. Plots of seed yams treated with neem recorded
reduced pests and damages in terms of parameters measured and subsequently
translated into yield. It is paramount to seed yam producers to adopt neem leaf
powder as pre-treatment for higher productivity.

Effects of Rhizome Extract of Dioscorea batatas and Its Active Compound, Allantoin, on the Regulation of Myoblast Differentiation and Mitochondrial Biogenesis in C2C12 Myotubes. Molecules 2018; 23:molecules23082023. [PMID: 30104552 PMCID: PMC6222821 DOI: 10.3390/molecules23082023] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2018] [Revised: 08/07/2018] [Accepted: 08/10/2018] [Indexed: 12/16/2022] Open
Abstract
With the aging process, a loss of skeletal muscle mass and dysfunction related to metabolic syndrome is observed in older people. Yams are commonly use in functional foods and medications with various effects. The present study was conducted to investigate the effects of rhizome extract of Dioscorea batatas (Dioscoreae Rhizoma, Chinese yam) and its bioactive compound, allantoin, on myoblast differentiation and mitochondrial biogenesis in skeletal muscle cells. Yams were extracted in water and allantoin was analyzed by high performance liquid chromatography (HPLC). The expression of myosin heavy chain (MyHC) and mitochondrial biogenesis-regulating factors, peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α), sirtuin-1 (Sirt-1), nuclear respiratory factor-1 (NRF-1) and transcription factor A, mitochondrial (TFAM), and the phosphorylation of AMP-activated protein kinase (AMPK) and acetyl-CoA carboxylase (ACC) were determined in C2C12 myotubes by reverse transcriptase (RT)-polymerase chain reaction (RT-PCR) or western blot. The glucose levels and total ATP contents were measured by glucose consumption, glucose uptake and ATP assays, respectively. Treatment with yam extract (1 mg/mL) and allantoin (0.2 and 0.5 mM) significantly increased MyHC expression compared with non-treated myotubes. Yam extract and allantoin significantly increased the expression of PGC-1α, Sirt-1, NRF-1 and TFAM, as well as the phosphorylation of AMPK and ACC in C2C12 myotubes. Furthermore, yam extract and allantoin significantly increased glucose uptake levels and ATP contents. Finally, HPLC analysis revealed that the yam water extract contained 1.53% of allantoin. Yam extract and allantoin stimulated myoblast differentiation into myotubes and increased energy production through the upregulation of mitochondrial biogenesis regulators. These findings indicate that yam extract and allantoin can help to prevent skeletal muscle dysfunction through the stimulation of the energy metabolism.

Xu HY, Zheng HC, Zhang HW, Zhang JY, Ma CM. Comparison of Antioxidant Constituents of Agriophyllum squarrosum Seed with Conventional Crop Seeds. J Food Sci 2018; 83:1823-1831. [PMID: 29870059 DOI: 10.1111/1750-3841.14159] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2017] [Revised: 03/10/2018] [Accepted: 03/19/2018] [Indexed: 11/26/2022]
Abstract
Twelve chemical constituents were identified from the Agriophyllum squarrosum seed (ASS). ASS contained large amounts of flavonoids, which were more concentrated in the seed coat. ASS-coat (1 g) contained 335.7 μg flavonoids of rutin equivalent, which was similar to the flavonoid content in soybean (351.2 μg/g), and greater than that in millet, wheat, rice, peanut, and corn. By LC-MS analysis, the major constituents in ASS were 3-O-[α-L-rhamnopyranosyl-(1→6)-β-D- glucopyranosyl]-7- O-(β-D-glucopyranosyl)-quercetin (1), rutin (4), quercetin-3-O-β-D- apiosyl(1→2)-[α-L-rhamnosyl(l→6)]-β-D-glucoside (2), isorhamnetin-3-O-rutinoside (5), and allantoin (3), compared with isoflavonoids-genistin (16), daidzin (14), and glycitin (18) in soybean. Among constituents in ASS, compounds 1, 2, 4, protocatechuic acid (8), isoquercitrin (11), and luteolin-6-C-glucoside (12) potently scavenged DPPH radicals and intracellular ROS; strongly protected against peroxyl radical-induced DNA scission; and upregulated Nrf2, phosphorylated p38, phosphorylated JNK, and Bcl-2 in HepG2 cells. These results indicate that ASS is rich in antioxidant constituents that can enrich the varieties of food flavonoids, with significant beneficial implications for those who suffer from oxidative stress-related conditions. PRACTICAL APPLICATION This study found that A. squarrosum seed contains large amounts of antioxidative flavonoids and compared its chemical constituents with those of conventional foods. These results should increase the interest in planting the sand-fixing A. squarrosum on a large scale, thus preventing desertification and providing valuable foods.

Abstract
Aging is now at the forefront of major challenges faced globally, creating an immediate need for safe, widescale interventions to reduce the burden of chronic disease and extend human healthspan. Metformin and rapamycin are two FDA-approved mTOR inhibitors proposed for this purpose, exhibiting significant anti-cancer and anti-aging properties beyond their current clinical applications. However, each faces issues with approval for off-label, prophylactic use due to adverse effects. Here, we initiate an effort to identify nutraceuticals-safer, naturally-occurring compounds-that mimic the anti-aging effects of metformin and rapamycin without adverse effects. We applied several bioinformatic approaches and deep learning methods to the Library of Integrated Network-based Cellular Signatures (LINCS) dataset to map the gene- and pathway-level signatures of metformin and rapamycin and screen for matches among over 800 natural compounds. We then predicted the safety of each compound with an ensemble of deep neural network classifiers. The analysis revealed many novel candidate metformin and rapamycin mimetics, including allantoin and ginsenoside (metformin), epigallocatechin gallate and isoliquiritigenin (rapamycin), and withaferin A (both). Four relatively unexplored compounds also scored well with rapamycin. This work revealed promising candidates for future experimental validation while demonstrating the applications of powerful screening methods for this and similar endeavors.

Abstract
A number of wild crops remain unexplored in this world and among them some have excellent medicinal and nutritional properties. India is a harbor of biodiversity in general and phytodiversity in particular. The plant diversity is distributed from the Western Ghats to Eastern Ghats, along with the North-Eastern region and from the Greater Himalayas to the plain of Ganga. Among these distributed floral regions of the country, the Eastern Ghats are important due to their rich floral diversity. The forests of Odisha form a major part of Eastern Ghats in general and the Similipal Biosphere Reserve (SBR) in particular. The SBR is inhabited by many local communities. The food and medicinal habits of these communities are not fully explored even today. They are dependent on the forests of SBR for their food and medicine. Among their collections from forests, root and tuberous plants play a significant role. The local communities of SBR use about 89 types of tuberous plants for various purposes. Dioscorea is one such tuber, having maximum use among the local of SBR. However, less documentation and no specific reports are available on the food and medicinal values of the species available in this part of the World. Dioscorea species, popularly known as Yam worldwide and as Ban Aalu in Odisha, India, is a prime staple medicinal-food substitute for the majority of rural and local people of the state of India. Of the 13 Dioscorea species available in SBR, 10 species are known to be bitter in taste and unpalatable when taken raw. Since less documentation is available on the Dioscorea species of SBR and their traditional uses, the present study was focused on the ethnobotany, nutritional and pharmacological values of these species along its nutraceutical importance.
