The effect of blue maize extract in factors related to metabolic syndrome (MS) in Wistar rats was investigated. Total polyphenols, monomeric anthocyanins, and antioxidant activity were analyzed in blue maize. MS was induced in Wistar rats fed with high-sucrose (HS) diet for 12 weeks. During a period of 4 weeks, blue maize extract was administrated to HS groups fed with high-sucrose and high-cholesterol–high-sucrose (HS+C) diets. In the blue maize extract administered by orogastric cannulation, the levels of total polyphenols and anthocyanins were 9.97 and 2.92 mg/kg of weight, respectively. HS diet administered during a period of 12 weeks increased significantly systolic blood pressure, serum triglycerides, and decreased high-density lipoprotein cholesterol (HDL-C), alterations related to the MS. Abdominal adipose tissue was only increased in the HS + C group. Blue maize extract administration enhanced HDL-C and decreased systolic blood pressure, serum triglycerides, total cholesterol, and epididymal adipose tissue weight. The blue maize may represent a promising nutraceutical option for the treatment of MS.

The metabolic syndrome (MS) underlies metabolic disorders considered risk factors for the development of diabetes and cardiovascular diseases, which are major causes of morbidity and mortality in most of the world. Sterculic acid has been proposed as a potential tool for the treatment of MS since it inhibits the activity of the stearoyl-CoA desaturase-1 (SCD1), a central enzyme in lipid metabolism. We analyzed the effect of sterculic oil (SO) co-administration with 30% fructose in drinking water on the development of MS in male Wistar rats. After 8 weeks, 0.4% SO exerted a protective effect from MS development since parameters altered by fructose (blood pressure, insulin resistance, serum glucose and triglycerides, steatosis, and adiposity) were similar to those of control rats.

Sterculia apetala (order: Malvales, family: Sterculiaceae) seed oil contains two cyclopropene fatty acids: sterculic and malvalic acid. Both positive and negative effects have been associated with the consumption of sterculic oil. In Mexico, S. apetala seeds are consumed after being boiled or roasted, used as chocolate flavoring, and utilized as animal fodder. Therefore, it is important to evaluate whether the consumption of this seed has a negative impact on the organism. The aim of this study was to evaluate the effect of administration of sterculic oil, during an 8-week period, on anxiety-like behavior and spontaneous locomotor activity in Zucker rats, analyzed through light/dark and open-field tests. The results showed that the consumption of sterculic oil decreased exploration latency in light/dark tests, which suggests an anxiolytic-like effect. Alterations in time spent on rearing and grooming were present in open-field tests, but this was not statistically significant, discarding nonspecific motor alterations. The alterations found in this study are possibly related to intrinsic obesity and metabolic complications present in the Zucker rat model, where leptin plays an important role in animal mood, more so than sterculic oil consumption.
