Plant-derived foods are esteemed as natural preventives due to the constraints of contemporary pharmaceuticals, intensifying scrutiny of traditional medicinal flora. This study marked the first extensive evaluation of the anti-diabetic, anticancer, and anti-inflammatory effects of Costus pictus rhizomes, expanding beyond its well-known anti-diabetic properties in leaves. Hot air-dried C. pictus rhizomes underwent ultrasound-assisted extraction to produce the rhizome extract. Anti-diabetic effects were determined through enzymatic inhibition studies targeting "α-amylase and α-glucosidase," crucial enzymes in glucose regulation, revealing potent inhibitory effects with IC50 values of 266.591 and 324.938 µg/ml, respectively. The ubiquity of breast cancer and constrained therapeutic alternatives for triple negative breast cancer led to the utilization of the "MDA-MB 231 cell line" for the study. The rhizome extracts demonstrated cytotoxicity at an IC50 concentration of 770 µg/ml, with a pronounced decline in the "reactive oxygen species (ROS)" and "mitochondrial membrane potential (MMP)." They also regulated the cell cycle arrest at the G2/M phase and positively induced apoptosis, thus making it a potent anticancer candidate. Anti-inflammatory effects were assessed using "RAW 264.7 macrophage cell line" and exhibited dose-dependent reduction with IC50 of 495.074 µg/ml, declining nitric oxide (NO) levels. Antimicrobial studies provided insights into its effectiveness against pathogens. This pivotal understanding laid groundwork for advancing C. pictus rhizome extract as a potential ingredient in pharmaceuticals or functional foods, leading to favorable health outcomes.

由于现代药物的限制,植物提取的食物被推崇为天然预防药物,从而加强了对传统药用植物群的研究。本研究首次对象拔蚌根茎的抗糖尿病、抗癌和抗炎作用进行了广泛评估,并超越了其叶片众所周知的抗糖尿病特性。热风干燥的象拔蚌根茎经过超声波辅助萃取,得到根茎提取物。通过针对 "α-淀粉酶和α-葡萄糖苷酶"(葡萄糖调节的关键酶)的酶抑制研究确定了其抗糖尿病作用,结果显示其抑制作用很强,IC50 值分别为 266.591 和 324.938 µg/ml。由于乳腺癌无处不在,且三阴性乳腺癌的治疗方法有限,因此研究采用了 "MDA-MB 231 细胞系"。根茎萃取物的细胞毒性IC50浓度为770微克/毫升,"活性氧(ROS)"和 "线粒体膜电位(MMP)"明显下降。它们还能调节细胞周期在 G2/M 阶段的停滞,并积极诱导细胞凋亡,从而使其成为一种有效的抗癌候选物质。使用 "RAW 264.7 巨噬细胞系 "对其抗炎作用进行了评估,结果表明,它的抗炎作用呈剂量依赖性降低,IC50 为 495.074 µg/ml,一氧化氮(NO)水平下降。抗菌研究深入揭示了它对病原体的有效性。这一关键性认识为将象拔蚌根茎提取物作为药物或功能性食品的潜在成分奠定了基础,从而带来良好的健康效果。

The study aimed to develop plant-based model snacks that are high in fibre, contain probiotic bacteria and are convenient for long-term storage. The research focused on selecting a suitable form of probiotic bacteria (active biomass, microencapsulated, freeze-dried), inoculation method (in the base mass or in the filling of a snack) and appropriate storage conditions (4°Cor 20 °C). The potential synbiotic properties were evaluated. The microencapsulated bacteria had the highest survival rate at 4 °C, while the freeze-dried bacteria showed better survival rates at 20 °C. Probiotics had a higher survival rate when enclosed inside snacks with a low water activity (aw = 0.27) peanut butter filling than in snacks without filling (aw = 0.53). Enclosing the probiotics in a low aw filling ensures their survival at ambient temperature for 5 months at a count higher than 6 log CFU/g. The snacks exhibited high antioxidant capacity (average 300 mg ascorbic acid equivalent/100 g), polyphenol content (average 357 mg gallic acid equivalent/100 g) and high fibre content (average 10.2 g/100 g). The sensory analysis showed a high overall quality of the snacks (average 7.1/10 of the conventional units). Furthermore, after six months of storage, significant changes were observed in the antioxidant properties, polyphenol content and texture of the snacks, while their sensory quality remained unchanged. Moreover, a potential synbiotic effect was observed. The method used to assess bacterial growth indicated significantly higher values in the model snacks compared to a control sample. Therefore, this study has effectively addressed the gap in knowledge regarding the survival of probiotics in snacks of this nature.

该研究旨在开发高纤维、含益生菌且便于长期储存的植物性模型零食。研究重点是选择合适的益生菌形式(活性生物质、微胶囊、冻干)、接种方法(接种在基质中或接种在点心馅料中)和适当的储存条件(4°C 或 20°C)。对潜在的益生特性进行了评估。微胶囊细菌在 4 °C 下的存活率最高,而冻干细菌在 20 °C 下的存活率更高。将益生菌包裹在低水活性(aw = 0.27)花生酱馅料的零食中,比包裹在无馅料(aw = 0.53)零食中的益生菌存活率更高。将益生菌包裹在低水活度馅料中可确保其在环境温度下存活 5 个月,存活率高于 6 log CFU/g。小吃具有较高的抗氧化能力(平均 300 毫克抗坏血酸当量/100 克)、多酚含量(平均 357 毫克没食子酸当量/100 克)和高纤维含量(平均 10.2 克/100 克)。感官分析表明,小吃的整体质量较高(平均为常规单位的 7.1/10)。此外,经过 6 个月的储存,零食的抗氧化特性、多酚含量和口感发生了显著变化,而感官质量保持不变。此外,还观察到了潜在的合生素效应。用于评估细菌生长的方法表明,与对照样本相比,模型零食中的细菌生长值明显较高。因此,这项研究有效地填补了有关益生菌在这类零食中存活的知识空白。

Phyllanthus emblica L. (syn. Emblica officinalis) fruits have been traditionally exploited to enhance the immune system and provide protection against bacterial and fungal diseases. The present study aimed to evaluate the synergistic interactions between chloramphenicol and several phenolic compounds found in P. emblica fruits against bacterial strains. The combination of P. emblica fruit extracts and its phenolic compounds demonstrated synergistic antibacterial activity when used in conjunction with chloramphenicol against both Gram-positive and Gram-negative bacteria. The combination of MICGA with ½MICChl exhibited a significant increase in bioactivity, with a 333.33-fold enhancement against B. subtilis. Similarly, the combination of MICGA with 2MICChl displayed a bioactivity enhancement of 16.02 folds against S. aureus. The co-administration of ½MICQ and ½MICChl resulted in a significant 35.71-fold increase in bioactivity against P. aeruginosa. Similarly, the combination of MIC GA and ½MICChl exhibited a remarkable 166.66-fold enhancement in bioactivity against E. coli. The combinations of 2MICFPE and ½MICChloramphenicol, as well as ½MICGA and ½MICChl demonstrated the highest bioactivity enhancement of 17.85 folds for K. pneumoniae. This study claimed that the fruit extracts of P. emblica and its phenolic compounds could be utilized to augment the effectiveness of conventional antibiotics, which have acquired resistance to bacterial infections.

传统上,人们利用大叶女贞(Emblica officinalis的同义词)的果实来增强免疫系统,抵御细菌和真菌疾病。本研究旨在评估氯霉素与从白皮冬青果实中发现的几种酚类化合物对细菌菌株的协同作用。将白皮松果实提取物及其酚类化合物与氯霉素结合使用,对革兰氏阳性菌和革兰氏阴性菌均具有协同抗菌活性。将 MICGA 与 ½MICChl 结合使用可显著提高生物活性,对枯草杆菌的活性提高了 333.33 倍。同样,MICGA 与 2MICChl 的组合对金黄色葡萄球菌的生物活性增强了 16.02 倍。同时使用 ½MICQ 和 ½MICChl 对铜绿假单胞菌的生物活性显著提高了 35.71 倍。同样,MIC GA 和 ½MICChl 的组合对大肠杆菌的生物活性显著提高了 166.66 倍。2MICFPE 和 ½MICChloramphenicol 以及 ½MICGA 和 ½MICChl 的组合对肺炎双球菌的生物活性增强了 17.85 倍。这项研究表明,可以利用大蒜的果实提取物及其酚类化合物来增强传统抗生素的效力,因为传统抗生素对细菌感染具有抗药性。

Mesoamerica is the center of origin of a great number of food crops that nowadays are part of a healthy diet. Pre-Columbian civilizations utilized more than 90% of these foods as ingredient or in main dishes, as well as for remedies and religious ceremonies. Since several years ago, Mesoamerican foods have been recognized by their outstanding concentration of bioactive compounds, including, phenolic compounds, pigments, essential fatty acids, amino acids, peptides, carbohydrates and vitamins, which provide a great number of health benefits. As a result of their unique composition, these ancient crops have several positive effects, such as hypoglycemic, antioxidant, anti-obesity, anti-inflammatory, anti-ageing, neuroprotective, anti-diarrheal, and anti-hypercholesterolemic capacity. Hence, this review is focused mainly in the anti-obesity and antioxidant potential of some of the most cultivated, harvested, as well as commercialized and consumed, food crops native of Mesoamerica, like, nopal and its fruit (Opuntia ficus indica spp.), chia (Salvia hispanica L.), pumpkin (Cucurbita spp.) and cacao (Theobroma cacao).

中美洲是大量粮食作物的原产地,这些作物如今已成为健康饮食的一部分。前哥伦布文明将这些食物中的 90% 以上用作配料或主菜,也用于治疗和宗教仪式。早在几年前,中美洲食品就因其富含生物活性化合物而得到认可,这些化合物包括酚类化合物、色素、必需脂肪酸、氨基酸、肽、碳水化合物和维生素等,对健康大有裨益。由于其独特的成分,这些古老作物具有多种积极作用,如降血糖、抗氧化、抗肥胖、抗炎、抗衰老、神经保护、止泻和降胆固醇。因此,本综述主要关注中美洲原产的一些最常种植、收获、商业化和消费的粮食作物的抗肥胖和抗氧化潜力,如罂粟及其果实(Opuntia ficus indica spp.)、奇亚籽(Salvia hispanica L.)、南瓜(Cucurbita spp.)和可可(Theobroma cacao)。

Fermented plant-based products are rapidly gaining popularity. Jerusalem artichoke is a medicinal plant that can be used to make fermented beverages. Samples were subjected to pretreatment (ultrasound at 35 kHz for 2, 4, and 6 min, freezing at -80 °C and -17 °C) while an untreated sample was used as control. It was shown that all types of pretreatments did not lead to an increase in protein, solids, polyphenols, and carbohydrates compared to the control sample. The greatest decrease in the values of these indicators occurs when pre-freezing tubers are used for Jerusalem artichoke dispersion production. It was also found that samples frozen at -80 °C had a significantly higher concentration of Ca, Si, Mg, and P whereas untreated samples frozen at -17 °C had more Al, K, Cu, Sr, and Cr. The processing method can affect the sensory descriptors of Jerusalem artichoke tuber dispersions to different extents, but the preference was for the control sample without pre-treatment. The fermentation of Jerusalem artichoke tuber dispersions demonstrated that S. thermophilus induced the most rapid fermentation (pH 4.75 in 5 h). The highest antioxidant activity after fermentation (55.39% FRSA) was shown for L. acidophilus H9, while the highest % FRSA value during the storage period was for L. bulgaricus (67.5%) on day 5 after fermentation. The highest viability among all selected microorganisms was detected for L. bulgaricus, L. acidophilus AT-41, and B. coagulans MTCC 5856 with the increase in biomass content by 2.3, 2.27, and 2.12 log10CFU/ml after fermentation. According to the results of sensory evaluation using hybrid hedonic scale the best results were shown for samples fermented with L. bulgaricus.

以植物为原料的发酵产品正在迅速普及。耶路撒冷蓟是一种药用植物,可用于制作发酵饮料。对样品进行预处理(35 kHz 超声波 2、4 和 6 分钟,-80 °C 和 -17 °C冷冻),同时使用未经处理的样品作为对照。结果表明,与对照样品相比,所有类型的预处理都不会导致蛋白质、固形物、多酚和碳水化合物的增加。在耶路撒冷洋蓟分散液生产中使用预冷块茎时,这些指标值的下降幅度最大。研究还发现,在-80 °C下冷冻的样品中,钙、硅、镁和磷的含量明显较高,而在-17 °C下冷冻的未处理样品中,铝、钾、铜、锶和铬的含量较高。加工方法会在不同程度上影响耶路撒冷朝鲜蓟块茎分散体的感官描述指标,但人们更倾向于未经预处理的对照样本。耶路撒冷朝鲜蓟块茎分散液的发酵结果表明,嗜热菌的发酵速度最快(5 小时内 pH 值为 4.75)。嗜酸乳杆菌 H9 在发酵后的抗氧化活性最高(55.39% FRSA),而保加利亚乳杆菌在发酵后第 5 天的 FRSA 值最高(67.5%)。在所有选定的微生物中,保加利亚乳杆菌、嗜酸乳杆菌 AT-41 和凝结芽孢杆菌 MTCC 5856 的活力最高,发酵后生物量含量分别增加了 2.3、2.27 和 2.12 log10CFU/ml。使用混合享乐量表进行感官评估的结果显示,使用保加利亚乳杆菌发酵的样品效果最佳。

This study aimed at comparing the carbohydrate composition of three banana varieties (cv. Nanica, Nanicão, and Prata) and investigating the effect of a single dose of cooked green banana pulp beverage (GBPd) on plasma glycemic homeostasis indexes (glucose, PYY, GIP, insulin) and hunger and satiety sensation (visual analog scale-VAS). The bananas were classified according to the color scale. The fiber, total carbohydrate, and resistant starch (RS) were determined using validated methods. Glucose homeostasis indexes and hunger/satiety sensation were determined in ten healthy women in two stages before and after intake: (1) glucose solution (250 g/L); (2) one week later, consumption of the glucose solution plus 75 g/L of GBPd. Blood samples were collected twice in stage-1 and every 15 min for 2 h in stage-2. Cv. Nanicão was selected, because it presented a higher content in RS and dietary fiber on dry base than the other cultivars. Thus, it was used to test glycemic response. After 2 h of GBPd intake, no difference was observed in hunger/satiety sensation and plasma glycemic homeostasis indexes, except for a decrease in plasma glucose concentration (-15%, p = 0.0232) compared to stage-1. These results suggest that cv. Nanicão has a higher potential as a functional ingredient and can influence the reduction in the glycemic index of a meal compared to other cultivars. However, it had not a short-term effect on hormones GIP and PYY in healthy women. Further research is needed to understand the long-term effects and mechanisms of green banana on glycemic control and satiety.

本研究旨在比较三个香蕉品种(Nanica、Nanicão和Prata)的碳水化合物组成,并调查单剂量煮熟的绿色香蕉果肉饮料(GBPd)对血浆血糖平衡指数(葡萄糖、PYY、GIP、胰岛素)以及饥饿和饱腹感(视觉模拟量表-VAS)的影响。香蕉根据色标进行分类。纤维、总碳水化合物和抗性淀粉(RS)均采用有效方法测定。10 名健康女性在摄入前后分两个阶段测定了葡萄糖稳态指数和饥饿/饱腹感:(1)葡萄糖溶液(250 克/升);(2)一周后,摄入葡萄糖溶液加 75 克/升的 GBPd。第一阶段采集两次血样,第二阶段在 2 小时内每 15 分钟采集一次血样。选择 Cv.之所以选择 Nanicão 品种,是因为该品种的 RS 和膳食纤维含量高于其他品种。因此,它被用来测试血糖反应。摄入 GBPd 2 小时后,除了血浆葡萄糖浓度下降(-15%,p = 0.0232)外,饥饿/饱腹感和血浆血糖平衡指数与第一阶段相比没有差异。这些结果表明,Cv.与其他栽培品种相比,Nanicão 作为功能性配料的潜力更大,可影响膳食血糖生成指数的降低。不过,它对健康女性体内的荷尔蒙 GIP 和 PYY 没有短期影响。要了解青香蕉对血糖控制和饱腹感的长期影响和机制,还需要进一步的研究。

Andean crops such as quinoa, amaranth, cañihua, beans, maize, and tarwi have gained interest in recent years for being gluten-free and their high nutritional values; they have high protein content with a well-balanced essential amino acids profile, minerals, vitamins, dietary fiber, and antioxidant compounds. During the germination bioprocess, the seed metabolism is reactivated resulting in the catabolism and degradation of macronutrients and some anti-nutritional compounds. Therefore, germination is frequently used to improve nutritional quality, protein digestibility, and availability of certain minerals and vitamins; furthermore, in specific cases, biosynthesis of new bioactive compounds could occur through the activation of secondary metabolic pathways. These changes could alter the technological and sensory properties, such as the hardness, consistency and viscosity of the formulations prepared with them. In addition, the flavor profile may undergo improvement or alteration, a critical factor to consider when integrating sprouted grains into food formulations. This review summarizes recent research on the nutritional, technological, functional, and sensory changes occur during the germination of Andean grains and analyze their potential applications in various food products.

近年来,藜麦、苋菜、卡尼花、豆类、玉米和塔尔维等安第斯作物因不含麸质和营养价值高而备受关注;这些作物蛋白质含量高,含有均衡的必需氨基酸、矿物质、维生素、膳食纤维和抗氧化化合物。在萌芽生物过程中,种子的新陈代谢被重新激活,导致宏量营养素和一些抗营养化合物的分解和降解。因此,萌发经常被用来改善营养质量、蛋白质消化率以及某些矿物质和维生素的可获得性;此外,在特定情况下,还可通过激活次级代谢途径来进行新生物活性化合物的生物合成。这些变化可能会改变技术和感官特性,如用它们配制的配方的硬度、稠度和粘度。此外,风味可能会得到改善或改变,这是将发芽谷物融入食品配方时需要考虑的一个关键因素。本综述总结了有关安第斯谷物发芽过程中营养、技术、功能和感官变化的最新研究,并分析了它们在各种食品中的潜在应用。

This study investigated the anti-inflammatory effect of hydrophilic and lipophilic extracts from juçara fruits (Euterpe edulis Martius) through measurement of nitric oxide (NOx) and cytokines (IL-12p70, TNF-α, INF-γ, MCP-1, IL-6, and IL-10). J774 macrophages were stimulated with lipopolysaccharides (1 µg/mL) and treated with various concentrations (1-100 µg/mL) of juçara fruits extracts from crude extracts, and hexane, dichloromethane, ethyl acetate, and butanol fractions. Potential relationships between the phenolic composition of the extracts determined by LC-ESI-MS/MS and their anti-inflammatory capacity were also evaluated. Hexane and dichloromethane fractions inhibited NOx and IL-12p70 while increased IL-10. Hexane fractions also decreased IL-6 and IFN-γ production. Hexane and dichloromethane fractions showed a higher number of phenolic compounds (32 and 34, respectively) than the other extracts tested and were also the only ones that presented benzoic acid and pinocembrin. These results suggest juçara fruits compounds as potential anti-inflammatory agents, especially those of a more apolar nature.

In Vitro Studies of Pumpkin (Cucurbita moschata var. Kashi Harit) Seed Protein Fraction(s) to Evaluate Anticancer and Antidiabetic Properties. 评估南瓜(Cucurbita moschata var.
IF 3.1 2区 农林科学 Q2 CHEMISTRY, APPLIED Pub Date : 2024-09-01 Epub Date: 2024-07-01 DOI: 10.1007/s11130-024-01205-7

Chronic diseases like cancer and diabetes are the major public health concerns of India and worldwide. Nowadays, plant-derived products are in great demand for the treatment of these diseases. Pumpkin seeds are traditionally implicated for their pharmacological properties, as exemplified by benign prostatic hyperplasia. Earlier, pumpkin seed proteins were extracted by the Osborne method, and their functional and nutritional qualities were evaluated. Here, the aim is to assess in vitro, the anticancer and antidiabetic properties of seed protein fractions. HepG2, MDA-MB-231, and MCF-7 cell lines were treated with water-soluble (WF) and alkali-soluble fractions (AF) to assess cytotoxicity, while pancreatic β-cells and insulin resistance (IR) - HepG2 cell lines were treated with WF to evaluate the antidiabetic potential. WF and AF showed cytotoxic effects towards HepG2 and MDA-MB-231 cell lines, suggesting apoptosis-mediated anticancerous activity. WF potentiates glucose-stimulated insulin secretion in pancreatic β-cells, in a dose-dependent manner. In IR-HepG2 cell line studies, control, metformin, and WF-treated groups showed uptake of glucose, when compared to the diabetic group, which is well-correlated with the upregulated expressions of GLUT2 and GLUT4 transporters in these groups. These results indicate that proteins from WF and AF may have anticancerous and antidiabetic properties and thus have the potential to utilize pumpkin proteins in the management of cancer and diabetes.

癌症和糖尿病等慢性疾病是印度乃至全球关注的主要公共卫生问题。如今,治疗这些疾病的植物提取物需求量很大。南瓜籽历来被认为具有药理特性,良性前列腺增生就是一例。早些时候,人们用奥斯本法提取了南瓜籽蛋白质,并对其功能和营养品质进行了评估。本文旨在体外评估南瓜籽蛋白质组分的抗癌和抗糖尿病特性。用水溶性(WF)和碱溶性(AF)馏分处理 HepG2、MDA-MB-231 和 MCF-7 细胞系,以评估细胞毒性;用 WF 处理胰岛β细胞和胰岛素抵抗(IR)- HepG2 细胞系,以评估抗糖尿病潜力。WF 和 AF 对 HepG2 和 MDA-MB-231 细胞株有细胞毒性作用,表明它们具有凋亡介导的抗癌活性。WF 能以剂量依赖的方式增强葡萄糖刺激的胰腺 β 细胞的胰岛素分泌。在IR-HepG2细胞系研究中,与糖尿病组相比,对照组、二甲双胍组和WF处理组都显示出对葡萄糖的吸收,这与这些组中GLUT2和GLUT4转运体的表达上调有很好的相关性。这些结果表明,WF 和 AF 的蛋白质可能具有抗癌和抗糖尿病的特性,因此有可能将南瓜蛋白质用于癌症和糖尿病的治疗。

Jackfruit leaf protein hydrolysates obtained from the enzymatic hydrolysis of leaf protein concentrate with gastrointestinal enzymes have shown good techno-functional properties and high antioxidant capacity. However, molecular weight, antiproliferative activity, cytotoxicity and the ability to reduce reactive oxygen species (ROS) are still unknown. Therefore, this study aimed to evaluate the effect of jackfruit leaf protein hydrolysates obtained by enzymatic hydrolysis with pepsin and pancreatin at different hydrolysis times (30-240 min) on molecular weights, cytotoxicity, antiproliferation of cancer cells, and the reduction of reactive oxygen species in H2O2-induced HaCaT cells. The electrophoretic profile indicated that H-Pep contains peptides with molecular weights between 25 - 20 kDa. Meanwhile, H-Pan is composed of molecular weight products between 25 - 20 kDa and < 20 kDa. H-Pan and H-Pep (125-500 µg/mL) did not show significant cytotoxicity on HaCaT (human keratinocytes) and J774A.1 (murine macrophage cells). Antiproliferative activity was achieved in human cervical, ovarian, and liver cancer cells. H-Pan-240 min (1000 µg/mL) reduced the cell viability of cervical cancer cells by 23% while H-Pan-60 min significantly reduced cell viability of ovarian and liver cancer cells by 14.5 (500 µg/mL) and 17% (1000 µg/mL), respectively (P < 0.05). The protective effect against oxidative stress on H2O2-stressed HaCaT cells was obtained with H-Pep-60 min, which reduced 25% of ROS at 250 µg/mL (P < 0.05). The findings demonstrate the safe use of green biomass as a source of plant protein hydrolysates.
