Jonatan Jafet Uuh Narvaez,Maira Rubı Segura Campos 한국식품영양과학회 2020 Journal of medicinal food Vol.23 No.4

The increase in the prevalence of diabetes has become a severe problem around the world; mainly affecting indigenous communities as the Mayan of Yucatán in Mexico. Because of the high rates of poverty and insufficient health services in this ethnic group, inexpensive and accessible treatments are necessary. Some plant foods grown in traditional Mayan agricultural systems have antidiabetic potential. Our objective was to present a review of plant foods with nutritional alternatives for diabetes prevention from traditional agricultural systems in Mayan communities of Yucatán. This review reports the hypoglycemic, antihyperglycemic, and antidiabetic activities of leaves, fruits, vegetables, grains and legumes, and tubercles grown in milpas and home gardens of Mayan communities. Some plant foods have antidiabetic effect in vitro, in vivo, and in clinical studies. Some plant foods grown in traditional Mayan agricultural systems have antidiabetic potential. The inclusion of these plant foods in the diet can serve in the treatment of diabetes.

Areli Carrera-Lanestosa,Yolanda Moguel-Ordonez,Maira Segura-Campos 한국식품영양과학회 2017 Journal of medicinal food Vol.20 No.10

Stevia rebaudiana (SR) is often used by the food industry due to its steviol glycoside content, which is a suitable calorie-free sweetener. Further, both in vitro and in vivo studies indicate that these glycosides and the extracts from SR have pharmacological and therapeutic properties, including antioxidant, antimicrobial, antihypertensive, antidiabetic, and anticancer. This work reviews the antiobesity, antihyperglycemic, antihypertensive, and antihyperlipidemic effects of the majority of glycosides and aqueous/alcoholic extracts from the leaves, flowers, and roots of the SR. These compounds can serve as a natural and alternative treatment for diseases that are associated with metabolic syndrome, thus contributing to health promotion.

A Mucuna pruriens protein concentrate was hydrolyzed with a digestive (pepsin–pancreatin) enzymatic system. The soluble portion of the hydrolysate was fractionated by ultrafiltration and the ultrafiltered peptide fraction (PF) with lower molecular weight was purified by reversed-phase high-performance liquid chromatography. The PF obtained were evaluated by testing the biological activity in vitro. Fractions showed that the ability to inhibit the angiotensin-converting enzyme had IC50 values that ranged from 2.7 to 6.2 μg/mL. Trolox equivalent antioxidant capacity values ranged from 132.20 to 507.43 mM/mg. The inhibition of human platelet aggregation ranged from 1.59% to 11.11%, and the inhibition of cholesterol micellar solubility ranged from 0.24% to 0.47%. Hydrophobicity, size, and amino acid sequence could be factors in determining the biological activity of peptides contained in fractions. This is the first report that M. pruriens peptides act as antihypertensives, antioxidants, and inhibitors for human platelet aggregation and cholesterol micellar solubility in vitro.

Steviol glycosides are a family of compounds found in Stevia rebaudiana Bertoni that are responsible for sweetness capacity. The antihyperglycemic effect of the two major steviol glycosides, Rebaudioside A and Stevioside, has been studied and it has been found that despite having the same common structure, only Stevioside exerts an antihyperglycemic effect. Although other steviol derivatives are found in smaller amounts (minor steviol glycosides) in S. rebaudiana, whether or not they possess antihyperglycemic activity has not been evaluated. The aim of this study was to evaluate the antihyperglycemic effect of minor steviol glycosides in normoglycemic and diabetic (streptozotocin/nicotinamide) Wistar rats. Rats were subjected to an intraperitoneal glucose tolerance test (IPGTT) both before and after chronic treatment (28 days). After 6 h of fasting, IPGTT was conducted in pentobarbital-anesthetized rats using 1 g/kg of glucose plus 20 mg/kg of the minor glycoside (Dulcoside A, Rebaudioside B, C, D, or Steviolbioside) or control treatment (distilled water, glibenclamide, or metformin); the blood of the tip of the tail was collected at time 0, 15, 30, 60, and 120 min.; and blood glucose was measured, and its net area under the curve (AUCnet) was calculated. After 28-day chronic oral administration, IPGTT was again performed. Differences were considered significant at P < .05 by one-way ANOVA. Acute intraperitoneal or chronic oral administration of 20 mg/kg of minor steviol glycosides had no antihyperglycemic effect in normoglycemic or induced-diabetic Wistar rats. Considering the dose tested, it is unlikely that these glycosides have an effect on glucose in diabetic or normoglycemic humans.

Salvia hispanica L. Seed Oil: Effect on Cell Viability in Colon Cancer Line Caco2 and Breast Cancer Line MCF7

Cancer is one of the main causes of mortality and morbidity worldwide, which does not have a fully effective medical treatment. Therefore, the objective of this study was to evaluate the effect of lipidically characterized and hydrolyzed chia seed (Salvia hispanica L.) oil on in vitro colon cancer (Caco2 cell line) and breast cancer cells (MCF7 cell line) cell viability. Cancer cells were treated with different hydrolyzed oil concentrations (12.5–400 μg/mL) for 48 h; then cell viability was assessed using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide assay. All chia seed oil concentrations significantly reduced cell viability in the Caco2 line, with the best reduction being 23.88% with the 25 μg/mL concentration. However, in the breast cancer line the highest concentrations (200 and 400 μg/mL) increased the viability of malignant cells. Chia seed oil significantly reduces the viability of Caco2 cells, although at the higher concentrations it can increase the viability of breast cancer cells.

In Mexico, Cnidoscolus aconitifolius (chaya) has been used to treat cardiovascular diseases (CVD). Because CVD are the number one cause of mortality, chaya use has become a health strategy. The aim of this study was to evaluate the antithrombotic activity and identify the metabolites in the most active extract. Aqueous (Aq), ethanolic (EtOH), acetonic (An), ethyl acetate (AcOEt), diethyl ether (Et2O), and hexanic (Hx) extracts were obtained. Platelet aggregation, phospholipase A2, prothrombin time (PT), activated partial thromboplastin time (aPTT), and clot lysis were evaluated. Metabolites were identified by gas chromatography–mass spectrometry (GC-MS). EtOH showed the greatest inhibition of platelet aggregation and phospholipase A2. Ac had the greatest effect on PT and aPTT. AcOEt had the greatest effect on clot lysis. EtOH, with the highest potential, was analyzed by GC-MS; fatty acids and triterpenes were identified. Thus, EtOH showed greater antiplatelet activity and other extracts showed moderate activity. This is a preliminary antithrombotic study. Future research will allow the development of nutraceuticals or functional ingredients for the prevention and treatment of thrombosis.
