Pecan nuts: A review of reported bioactivities and health effects
Scopus
Toplam 163 atıf DOI
Background Food choices represent a highly significant approach to combat human obesity. Dietary intake of lipids, especially polyunsaturated and monounsaturated fatty acids, is gaining popularity in the effort to reduce or eliminate the occurrence of obesity. Pecan (Carya illinoinensis) nuts are an abundant source of these dietary fatty acids. Moreover, they are a rich source of epigallocatechin-3-gallate (EGCG), a polyphenol with a variety of health-beneficial properties. Scope and approach In this review, we summarize the literature reports examining physiological effects associated with pecan nuts consumption and described effects of their bioactive constituents. Key findings and conclusions The growing body of evidence suggests including pecan nuts into obesity management strategies. The consumption of pecan nuts can mitigate inflammation by reducing the extent of the synthesis of inflammatory mediator molecules. Pecan nuts can also counteract the pro-inflammatory effects of a diet rich in commonly overconsumed saturated fatty acids, characteristic of the Western diet. Additionally, consumption of pecans and other nuts has been linked to reduced risk of physiological parameters associated with cardiovascular disease or metabolic disorders. Diets enriched with tree nuts and peanuts can modulate the blood level of cholesterol, adiposity, and insulin resistance. Almonds and walnuts have been so far the most studied nuts, and studies with them have led to a greater understanding of the protective effects of diverse tree nuts on human physiology. In this review, we summarize the available data indicating that pecan nuts exert similar health-promoting benefits.

Members of the genus Euphorbia have attracted much interest as potential sources of bioactive compounds. In this study, the ethyl acetate, methanolic and aqueous extracts of aerial parts of three Euphorbia species namely Euphorbia hirta L., Euphorbia heterophylla L. and Euphorbia convolvuloides Hochst. ex Benth. were screened for their antioxidant [2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), ferric reducing antioxidant power (FRAP), cupric antioxidant reducing capacity (CUPRAC), metal chelating, total antioxidant capacity (phosphomolybdenum)], and enzymatic properties [α-amylase, α-glucosidase, tyrosinase, acetyl- (AChE), butyryl-cholinesterase (BChE)]. Total phenolic (TPC), total flavonoid content (TFC) and phytochemical profile were established via LC-DAD-MSn. Results showed that the methanolic and aqueous extracts of the three plants yielded the highest TPC with values ranging from 35.84–141.90 mg gallic acid equivalent/g. E. hirta was the most potent DPPH scavenger and chelator reporting the highest equivalent [DPPH: 195.22 mg Trolox equivalent (TE)/g, chelator: 30.73 mg ethylenediaminetetraacetic acid equivalent (EDTAE)/g], while E. heterophylla demonstrated the most significant Fe3+ and Cu2+ reducing potential (FRAP: 194.28 mg TE/g; CUPRAC: 631.25 mg TE/g) and possessed the highest total antioxidant capacity (3.76 mmol TE/g). The AChE, BChE, α-amylase and α-glucosidase enzyme inhibitory effects of the three species were relatively the same. However, E. hirta exhibited the highest anti-tyrosinase activity (109.71 mg kojic acid equivalent /g). Euphorbia convolvuloides showed low antioxidant activities and enzymatic inhibitory effects compared to other. LC-DAD-MSn fingerprint of the phenolics of the three species showed the presence of different derivatives. Quantitative data revealed tannins and flavonoids (25 and 20 mg/g respectively) for E. hirta, high amount of tannins 63 and 21 mg/g of flavonoids for E. heterophylla, while high flavonoid contents for E. convolvuloides, 56 mg/g. Euphorbia hirta proved to the most promising among the three tested species and thus can be explored further by isolating and characterizing active bioactive agents that could be used to manage oxidative stress-related diseases and hyperpigmentation problems.
