Abstract
Allium hookeri (F: Liliaceae), an indigenous plant of Manipur, India, is traditionally used to treat various diseases and disorders like diabetes, hypertension, and stomach ache. In our previous study, the methanol extract of the plant showed significant antidiabetic potential in rats. In the present study, we evaluated the antidiabetic potential of a flavonoid compound named MEA isolated from the methanolic leaf extract of A. Hookeri in rats. Additionally, we assessed the compound's mode of action through the molecular docking study. The MEA reduced the blood glucose level from 317±12.8 to 99.4±6.67 mg/dl after 21 days of treatment. Besides, MEA also restored the body weights and other biochemical parameters including lipid profile significantly compared to the diabetic group (p<0.001). The histoarchitecture of the pancreatic tissues of the MEA treated group was also improved compared to the diabetic group. In the docking study, the compound showed good binding affinity in the active binding site of the two structures of pancreatic beta-cell SUR1 (Sulfonylurea Receptor 1) subunit with CDocker energy -31.556 kcal/mol and -39.703 kcal/mol, respectively. The compound MEA was found to be drug-like with non-carcinogenic, non-mutagenic and non-irritant properties. These findings indicate the antidiabetic potential of MEA, which might act by modulating the pancreatic beta-cell SUR1 subunit present in the KATP channel. Hence, the MEA would be a promising lead molecule to develop new antidiabetic drug candidates of the future.

Abstract
The plant Allium hookeri, a member of the Allium genus, has a rich history of culinary and medicinal use. Recent studies have unveiled its potent antioxidant and anti-inflammatory properties. While research on A. hookeri has demonstrated its neuroprotective and anti-neuroinflammatory effects, the specific bioactive compounds responsible for these effects remain unidentified in prior research. This study utilized an untargeted metabolomic approach, employing HRESI-qTOF MS/MS-based molecular networking, to comprehensively profile the chemical composition of metabolites in A. hookeri and identify new compounds within the plant. As a result, ten compounds, comprising one novel flavonoid (2) and nine known compounds (1 and 3-10), were isolated and identified through NMR analysis. The inhibitory effects of all isolated compounds on the senescent cell-associated secretory phenotype (SASP), which is pivotal in neuroprotective actions, were evaluated. Biological activity testing revealed N-trans-feruloyltyramine (7) to be the most potent compound, effectively inhibiting SASP markers and contributing to the senomorphic activities of A. hookeri. These findings underscore the potential of phenolamides from A. hookeri as a promising source of bioactive compounds for mitigating senescence-associated diseases.

Abstract
Allium hookeri (AH) has been used as a nutritional and medicinal food in Asia for many years. Our previous studies have described its anti-diabetic, anti-obesity, and anti-inflammatory activities in animal models and prediabetes. This study investigated whether AH could improve glycemia by modulating insulin secretion in prediabetic subjects through an in-depth study. Eighty prediabetic subjects (100 ≤ fasting plasma glucose < 140 mg/dL) were randomly assigned to a placebo (n = 40) group or an ethanol AH extract (500 mg/day, n = 40) group for 12 weeks. Dietary intake and physical activity, blood glucose (an oral glucose tolerance test for 120 min), insulin (insulin response to oral glucose for 120 min), area under the curve (AUC) of glucose or insulin after oral glucose intake, insulin sensitivity markers, C-peptide, adiponectin, glycated hemoglobin A1c (HbA1c) levels, hematological tests (WBC, RBC, hemoglobin, hematocrit, and platelet count), blood biochemical parameters (ALP, AST, total bilirubin, total protein, albumin, gamma-GT, BUN, creatinine, LD, CK, and hs-CRP), and urine parameters (specific gravity and pH) were examined at both baseline and 12 weeks after supplementation with placebo or AH capsules. Fifty-eight participants (placebo group: 20 men and 10 women; AH group: 13 men and 15 women) completed the study. AH supplementation moderately reduced postprandial blood glucose at 60 min (-6.14 mg/dL, p = 0.061), postprandial insulin levels at 90 min (-16.69 µU/mL, p = 0.017), the glucose AUC at 90 min (-412.52 mg*min/dL, p = 0.021), as well as the insulin AUC at 90 min (-978.77 µU*min/mL, p = 0.021) and 120 min (-1426.41 µU*min/mL, p = 0.015) when compared with the placebo group. However, there were no effects of AH on dietary intake and physical activity; HOMA index; HbAlc; C-peptide; or adiponectin, hematological-, blood biochemical-, and urinary markers. To confirm the effects of AH extract on blood glucose insulin sensitivity, C57BL/6J or C57BL/KsJ-db/db mice were used (n = 8/group). Body weight, fasting plasma glucose level, lipid profiles, liver and renal function, pancreatic histology, and insulin immunoreactivity were assessed. In the diabetic db/db mice, hyperglycemia, which was accompanied by an increase in insulin secretion in diabetic mice, was significantly reduced by AH treatment, resulting in the alleviation of β-cell overcompensation and insulin resistance. We confirmed that AH supplementation can effectively control blood glucose and insulin levels by improving insulin sensitivity and may be a potential agent for glycemic control in subjects with prediabetes and type 2 diabetes mellitus.

Abstract
Oxidative stress and cellular senescence in dermal papilla cells (DPCs) are major etiological factors causing hair loss. In this study, the effect of the Allium hookeri extract (AHE) on hair-inductive and anti-oxidative properties was investigated in human DPCs. As a result, it was found that a non-cytotoxic concentration of the extracts increased the viability and size of the human DPC spheroid, which was associated with the increased expression of hair-growth-related genes in cells. To determine whether or not these effects could be attributed to intracellular anti-oxidative effects, liquid chromatography-mass spectrometry alongside various biochemical analyses are conducted herein. An ingredient called alliin was identified as one of the main components. Furthermore, AHE treatment induced a significant decrease in H2O2-mediated cytotoxicities, cell death, and cellular senescence in human DPCs. Upon analyzing these results with a molecular mechanism approach, it was shown that AHE treatment increased β-Catenin and NRF2 translocation into the nucleus while inhibiting the translocation of NF-κB (p50) through p38 and PKA-mediated phosphorylations of GSK3β, an upstream regulator of those proteins. These results overall indicate the possibility that AHE can regulate GSK3β-mediated β-Catenin, NRF2, and NF-κB signaling to enhance hair-inductive properties and ultimately protect against oxidative stress-induced cellular damage in human DPCs.

Abstract
This study was conducted to evaluate whether Allium hookeri can control diabetic symptoms. Aqueous extract (AE1: 100 mg/kg BW, AE2: 200 mg/kg BW) and ethanol extract (EE1: 100 mg/kg BW, EE2: 200 mg/kg BW) of A. hookeri were orally administrated to diabetic mice (C57BL/J-db/db) for 8 weeks. The negative (NC) and the positive (PC) control groups were treated with 0.9% saline and metformin (150 mg/kg BW), respectively. Glucose and lipid profile (triglyceride, total cholesterol (TC), LDL-C, and HDL-C) as biochemical parameters, toxicological factors such as liver/kidney functional parameters (ALT, AST, BUN, and Cr), and NK cell activity in blood were measured. Oral glucose tolerance test (OGTT) and histopathological examination were also conducted. Compared with the NC group, AE and EE decreased blood glucose, HbA1c, area under the curve (AUC) during OGTT, and leptin levels while increasing adiponectin levels. Serum lipid profiles and toxicological factors levels were reduced by the A. hookeri extract. Interestingly, HDL-C, glomerular mesangial expansion score in the kidney, and NK cell activity were effectively controlled in EE groups. Based on the results, EE is considered to be more effective in reducing high blood glucose, lipid profile, and related factor levels than AE, and is comparable to metformin in some biomarkers. It can be presumed that EE can more effectively control the major anomalies in the diabetic model than AE, and it may be used to prevent diabetic symptoms without toxicity in the Type 2 diabetic model.

Abstract
Allium hookeri (AH) is a medicinal food that has been used in Southeast Asia for various physiological activities. The objective of this study was to investigate the activation of the cholinergic system and the anti-neuroinflammation effects of AH on scopolamine-induced memory impairment in mice. Scopolamine (1 mg/kg body weight, i.p.) impaired the performance of the mice on the Y-maze test, passive avoidance test, and water maze test. However, the number of error actions was reduced in the AH groups supplemented with leaf and root extracts from AH. AH treatment improved working memory and avoidance times against electronic shock, increased step-through latency, and reduced the time to reach the escape zone in the water maze test. AH significantly improved the cholinergic system by decreasing acetylcholinesterase activity, and increasing acetylcholine concentration. The serum inflammatory cytokines (IL-1β, IL-6, and IFN-γ) increased by scopolamine treatment were regulated by the administration of AH extracts. Overexpression of NF-κB signaling and cytokines in liver tissue due to scopolamine were controlled by administration of AH extracts. AH also significantly decreased Aβ and caspase-3 expression but increased NeuN and ChAT. The results suggest that AH extracts improve cognitive effects, and the root extracts are more effective in relieving the scopolamine-induced memory impairment. They have neuroprotective effects and reduce the development of neuroinflammation.

Abstract
Oxidative stress resulting from the depletion of glutathione (GSH) level plays a vital role in generating various degenerative diseases, including type 2 diabetes (T2D). We tested the hypothesis that depleted glutathione levels can be enhanced and the impaired glucose metabolism can be prevented by supplementing Allium hookeri, a herb rich in organosulfur compounds, in a High Fat (HF) diet-induced T2D Male Sprague Dawley rat model. The experimental rats were divided into three groups (n = 6), namely normal diet, high-fat diet, and high-fat diet treated with A.hookeri methanolic leaf extract (250 mg/kg). Consumption of HF diet along with the plant extract resulted in significant reduction of the body weight (7.08%-14.89%) and blood glucose level (6.5%-16.4%) from the 13th week onward. There was a significant decrease in reactive oxygen species, oxidized glutathione (GSSG) levels, and an increase in GSH level in skeletal muscle tissues supplemented with the plant extract. The protein expressions of the signaling molecules such as GCLC and GR involved in GSH synthesis and of GLUT4 in glucose transport were also upregulated in the skeletal muscle tissues of the plant extract-treated group. Results of in vitro studies with muscle cell line (L6) further demonstrated the beneficial effect of the plant extract in increasing glucose uptake and maintaining the GSH/GSSH equilibrium via regulation of protein expression of GCLC/GR/GLUT4 signaling molecules in sodium palmitate (0.75 mM) treated cells. Overall this study suggests that dietary supplementation with Allium hookeri, can restore the glutathione level and regulate the blood glucose level in T2D.

Abstract
Cheese contains various beneficial nutrients, including calcium and whey protein, as well as large amounts of saturated fatty acids. Thus, intake of cheese increases the production of low-density lipoprotein-cholesterol (LDL-C), a well-defined risk factor for cardiovascular disease. Therefore, identification of natural products that inhibit LDL-C production following cheese intake and verification of the efficacy of such products in animal models are essential. Here, we evaluated the effects of Allium hookeri, a well-known traditional herbal remedy, on metabolism and thermogenesis in mice consuming a cheese-containing diet. Intake of A. hookeri extracts significantly blocked increases in body weight and fat mass caused by intake of Gouda cheese in mice. Additionally, increases in blood triglyceride levels following intake of Gouda cheese were alleviated by A. hookeri. Moreover, intake of Gouda cheese enhanced thermogenesis efficiency. Thus, A. hookeri may have applications as an important additive for reducing the risk of metabolic disease resulting from cheese consumption.

Abstract
In this study, the anti-oxidative and neuro-protective effects of ethanolic extracts of the dried roots of Allium hookeri were investigated. Total phenolic contents and total flavonoid contents of A. hookeri extract depended on the ethanol concentrations used (50, 70 and 95%). In order to evaluate radical scavenging activity, DPPH and ABTS radical scavenging assays and ferric reducing powers were evaluated. The results showed the 95% ethanol extract of A. hookeri (95AH) had higher phenolic and flavonoid contents, and greater radical scavenging activities than 50 or 70% ethanol extracts of A. hookeri. The neuro-protective effects of 95AH were evaluated using H2O2-treated PC12 neuronal cells. Treatment of 95AH increased cell viability and superoxide dismutase and glutathione peroxidase activities, reduced lactate dehydrogenate release, reduced reactive oxygen species production, and increased Bcl-2/Bax ratio. HPLC revealed 95AH was rich in phenolics, especially catechin. These results demonstrate 95AH has substantial anti-oxidative and neuro-protective effects against H2O2-induced oxidative stress.

Abstract
Background Allium hookeri is widely consumed as a vegetable and herbal medicine in Asia. A. hookeri has been reported anti-inflammatory, anti-obesity, osteoblastic, anti-oxidant, and anti-diabetic effects in animal studies. We investigated the anti-diabetic effects of A. hookeri aqueous extract (AHE) in the Korean subjects. Methods Prediabetic subjects (100 ≤ fasting plasma glucose (FPG) < 126 mg/dL) who met the inclusion criteria were recruited for this study. The enrolled subjects (n = 30) were randomly divided into either an AHE (n = 15, 486 mg/day) or placebo (n = 15) group. Outcomes were measurements of FPG, glycemic response to an oral glucose tolerance test (OGTT), insulin, C-peptide, hemoglobin A1c (HbA1c), total cholesterol, triglyceride, HDL-cholesterol, and LDL-cholesterol. The t-test was used to assess differences between the groups. A p-value < 0.05 was considered statistically significant. Results Eight weeks after AHE supplementation, HbA1c level was significantly decreased in the AHE group compared with the placebo group. No clinically significant changes in any safety parameter were observed. Conclusion The findings suggest that AHE can be effective in reducing HbA1c, indicating it as an adjunctive tool for improving glycemic control. Trial registration The study protocol was retrospectively registered at www.clinicaltrials.gov (NCT03330366, October 30, 2017).

Abstract
This study was performed to investigate the antioxidative and sensory properties of Allium hookeri fermented by Leuconostoc mesenteroides in pork patties. The patties were divided into three groups: CON, with no Allium hookeri powder; AH, containing 1% Allium hookeri powder; and FAH, containing 1% fermented Allium hookeri powder. Allium hookeri fermented by L. mesenteroides significantly increased the radical scavenging activities of 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) compared to that in normal Allium hookeri (p<0.05). The cooking loss and expressible drip for FAH were significantly lower than the corresponding values of other groups (p<0.05). The pH and 2-thiobarbituric acid reactive substances value of the FAH were significantly lower than that of CON on the day 3 and 7 (p<0.05). In the texture analysis (TPA), FAH showed significantly decreased hardness and chewiness grades compared to the CON and AH (p<0.05). FAH had significantly higher color, flavor, tenderness, juiciness, and overall acceptability scores than the CON and AH (p<0.05). This study suggests that the adding fermented Allium hookeri effectively improved the quality characteristic of the food.

Abstract
Blockade of caspase-1 was reported to be a new target for allergic inflammation treatment. Here, we present the effect of linoleic acid (LA), a constituent of Allium hookeri (AH), to alleviate mast cell-mediated allergic inflammation. Pretreatment of LA and AH significantly reduced caspase-1 activation without displaying host cell cytotoxicity in activated human mast cells. IC50 value of LA on caspase-1 activity is 0.014 μM. LA and AH pretreatment effectively regulated increased levels of interleukin (IL)-1β, IL-6, IL-8, thymic stromal lymphopoietin, and tumor necrosis factor on activated human mast cells. Moreover, LA and AH were effective against activations of nuclear factor-κB and mitogen-activated protein kinases in human mast cells. In summary, LA and AH alleviate allergic inflammatory reactions via blocking caspase-1 cascade signaling pathway. These results provide evidence for the anti-allergic inflammatory properties of LA and AH and corroborate its potential use for the treatment and prevention of allergic diseases. PRACTICAL APPLICATIONS: Allium hookeri (AH) is used as traditional food to treat various diseases and contains an essential fatty acid, linoleic acid (LA). LA and AH alleviate mast cell-mediated allergic inflammatory reactions via inhibiting inflammatory mediators. These results provide evidence for the anti-allergic inflammatory properties of LA and AH and corroborate its potential use for the treatment and prevention of allergic diseases.

Abstract
The antioxidant effects of Allium hookeri root (AHR) were investigated by evaluating lipid and protein oxidation in meatballs during refrigerated storage at 4±1℃. AHR was mixed at concentrations of 0.5% (w/w, T2) and 1% (w/w, T3) with minced longissimus dorsi muscle. Meatballs containing AHR (T2 and T3) were compared to those containing 0.05% (w/w) ascorbic acid (T1) as a reference and without antioxidant as a control. The 2-thiobarbituric acid reactive substances (TBARS) value, disulfide bond formation, carbonyl contents, and volatile basic nitrogen (VBN) value of T2 were lower than those of the control during storage (p<0.05). The pH values of T2 and T3 were higher than that of the control (p<0.05). Texture profile analysis of T2 revealed a lower value compared to the control (p<0.05). Therefore, the VBN value, TBARS value, disulfide bond formation, and carbonyl content in meatball containing AHR were lower than those of the control meatball. These results indicate that AHR improves the quality of meat products and functions as an antioxidant.

Abstract
Allium hookeri is widely consumed plant as a vegetable and herbal medicine in southeastern Asia. Allium hookeri has been reported antioxidant, improvement of bone health and antidiabetic effects. In the present study, we investigated the potential inhibitory effect of Allium hookeri extract (AHE) on Helicobacter pylori. The in vitro anti-bacterial activities of AHE were determined by disk agar diffusion method. Also, the inhibition effect of the AHE on H. pylori infection was investigated using a mouse model. H. pylori colonization was confirmed by rapid urease tests, as described previously. Mucosal damage was evaluated grossly and histologically according to previously described criteria. As the results of the disk agar diffusion assay, CLR, AMX and MTZ inhibited the bacterial growth with inhibition zone of 19.2, 15.2 and 7.5 mm, respectively. AHE 100 µg/mL showed an inhibition zone value of 20.6 mm. Rapid urease tests of the mice stomachs demonstrated a significant reduction in H. pylori colonization. In addition to the therapeutic effect against H. pylori infection, the AHE reduced mucosal inflammation and epithelial damages in the stomach of H. pylori-infected mice. These results demonstrate that the AHE successfully cured an H. pylori infection and treated the H. pylori infection. This AHE could be a promising treatment for patients with gastric complaints including gastritis caused by H. pylori.

Abstract
The objective of this experiment was to evaluate the antioxidant potential of Allium hookeri (AH) root in two forms, powdered AH root and fermented powdered AH root, to demonstrate its value as an antibiotic alternative feed additive for broiler chickens. A total of 125 male Ross-708 broiler chickens were randomly assigned to five groups (n = 25 birds/group) and fed standard diets supplemented with root or fermented root of AH at two different levels (1% or 5%). Control birds were provided with non-supplemented basal diets. Body weights was measured at days 14 and 21 of age. To monitor antioxidant activities, heme oxygenase (HMOX), aflatoxin B1 aldehyde reductase (AFAR), superoxide dismutase 1 (SOD1), and catalase (CAT) enzyme levels were quantified by real-time PCR in the jejunums 21-day-old birds. Also, serum levels of SOD, CAT, and malondialdehyde (MDA) were measured using commercial kits. The results showed greater body weight gains at day 14 in chickens fed diets supplemented with 1% AH root, as compared to the control group (p < 0.05). Up-regulated transcript levels of AFAR, HMOX1, and CAT were observed in the jejunum of chickens fed diets supplemented with AH. The serum levels SOD and CAT were significantly increased (p < 0.05) in groups treated with AH, whereas MDA levels were decreased in groups fed diets supplemented with AH, as compared to the control group. These results indicated that an optimum level of dietary AH supplementation to young broiler chickens influences growth and improves antioxidant activities.

Abstract
Background Allium hookeri (AH) is widely consumed as a vegetable and herbal medicine in southeastern Asia. AH has been reported antioxidant, antimicrobial, improvement of bone health and antidiabetic effects. In the present study, we investigated the inhibitory effect of a methanol extract of AH root (AHE) on inflammatory response in lipopolysaccharide (LPS)-induced RAW264.7 cells. Methods Initially, characterization of organic sulfur compounds in AHE was determined using high performance liquid chromatography-electrospray ionization-mass spectrometry (HPLC-ESI-MS). Cells were incubated with LPS and AHE for 24 h. The productions of nitric oxide (NO), reactive oxygen species (ROS), and inflammation-related cytokines were examined. Gene and protein expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) were assessed by polymerase chain reaction and Western blotting. Key factor, nuclear factor kappa B (NF-κB) was also determined. Results AHE contained organosulfur compounds such as alliin and S-allylcysteine by HPLC-ESI-MS. AHE significantly inhibited NO, ROS, and cytokines production in LPS-induced RAW264.7 cells. In addition, AHE treatment inhibited iNOS and COX-2 mRNA and protein levels, leading to a decrease in iNOS-derived NO level. Furthermore, NF-κB activation was, at least in part, suppressed by AHE treatment. Conclusion Our data suggest that AHE treatment inhibits the inflammation condition through suppression of iNOS and COX-2 expression via NF-κB down-regulation.

Abstract
The present study investigated the effects of ethanol extracts of Allium hookeri (leaf, root, and fermented root) on parameters of innate immunity, tumour cell viability and antioxidant effect in vitro. Innate immunity was measured by spleen lymphocyte proliferation, nitric oxide production by chicken macrophage HD11 cells and suppressive effect on tumour cell viability was assessed using chicken RP9 cells. Free radical scavenging capacity as a measure of antioxidant capacity was determined by 0.15 mM of DPPH solution. In vitro culture of chicken spleen lymphocytes with ethanol extract of Allium hookeri (62.5–500 µg/mL) significantly induced higher proliferation compared with media control. Stimulation of macrophages with ethanol extract of Allium hookeri (62.5–500 µg/mL) showed increased Nitric oxide production. Tumor cells growth was significantly inhibited by extracts of Allium hookeri at 15.6–125 µg/mL compared with medium control and all extracts exhibited greater than 80% scavenging activity at 1000 µg/mL compared with ethanol vehicle control. Above all, fermented root extracts showed strongest effects on antioxidant activity compared to leaf and root extracts.

Abstract
Anti-adipogenic and antidiabetic activities of Allium hookeri root water extracts (ARW) were assessed. Oil Red O staining showed that treatment with ARW caused a dose-dependent reduction in lipid accumulation. ARW was also involved in adipocyte lipolysis via LPL activity, and in the concentration of glycerol in a culture medium. On the basis of the concentration of adipokines following ARW treatment, ARW appeared to inhibit expression of PPAR-γ, to reduce concentrations of leptin and resistin, to increase the concentration of adiponectin, and to inhibit lipid accumulation. ARW modulated adipokine expression associated with insulin resistance and sensitivity. 3T3-L1 adipocytes treated with ARW showed increased GLUT-4 expression with increased glucose uptake into adipocytes. ARW showed effectiveness for improvement of diabetic conditions.

Abstract
The effect of the addition of Allium hookeri on the quality of fermented sausage made with meat from sulfur fed pigs was examined, throughout a 60 d ripening period. There were two treatments in animal management: normal feed fed pigs, and sulfur fed pigs given 0.3% sulfur mixed normal feed. Fermented sausage manufactured with meat from normal feed fed pigs, and with meat from sulfur fed pigs, and 1% A. hookeri-containing fermented sausage processed with meat from sulfur fed pigs, were determined at 1 d, 15 d, 30 d, and 60 d. The meat qualities in fermented sausage were measured by DPPH radical scavenging activity (DPPH), ABTS(+) radical scavenging activity (ABTS(+)), total phenolic acids, and total flavonoid contents. Fermented sausage made from pigs that had been fed with 0.3% sulfur was protected from oxidation by reduced free radical, as shown by the significant increase in DPPH and ABTS(+) values, compared with fermented sausage made from normal feed fed pigs (p<0.05). A. hookeri-added fermented sausage with sulfur fed pork was shown to increase the values in DPPH, ABTS(+), total phenolic acid, and total flavonoid contents, by comparison with both the control sausage, and sausage with sulfur fed pork, at 60 d. These results suggest that A. hookeri in meat from sulfur fed pigs could be a source of natural addition, to increase quality in the food industry.
