The biochemical significances of the proximate, mineral and phytochemical composition of selected vegetables from Pakistan

Abstract

Current study was designed to focus on the proximate, phytochemical and nutrient composition in addition to antioxidant properties of five selected vegetables viz Ipomoea batatas, Trigonella foenum-graecum, Daucus carota, Solanum Melongena and Brassica rapa rapa that are locally available and readily consumed in Pakistan. Nutritional analysis revealed that all the edibles were rich sources of crude protein, carbohydrate, fat and dietary fiber. Micro and macro minerals analysis also exhibited the significant presence of Na, K, Ca, Mg and P. Preliminary phytochemical screening unveiled the extraordinary incidence of alkaloids, saponins, tannins, flavonoids that was also proved by quantitative analysis. The biological assays bared a considerable antioxidant potential of selected green materials. Among vegetables, Trigonella foenum-graecum was proved to be superior while Brassica rapa rapa was considered to be inferior for phenolics and flavonoids content. Trigonella foenum-graecum also presented significant antioxidant activity with maximum reduction capacity and also having least IC50 as a result of inhibition of free radical scavenging by DPPH method. In contrast to α-amylase, a significantly higher inhibition towards α-glucosidase was shown by the selected samples; an impending remedial approach connected to postprandial hyperglycemia. In this scenario, the results of this study suggests that all the selected green materials have very good medicinal potentials, meet the standard requirements for drug formulation and serve as good sources of energy and nutrients. The outcomes of current work also revealed that plant derived foods enriched with phytoprotectants are effective to tailor specific healthy diet for the target population.

“…Each sample was analyzed using less than 10 mg of powder (Atta et al, 2017). Thermogravimetric spectra were measured from room temperature to 750 °C using a TG20 thermal gravimetric analyzer (209-F1 TG, Netzsch, Germany) and a carrier gas (N 2 ) velocity of 40 mL/min.…”

Effect of different component ratio of Astragalus total saponins and Verbena total glycosides on the cerebral infarction area and serum biochemical indicators in the focal cerebral ischemia-reperfusion rat model

“…In modern medical research, the pathogenesis of cerebral ischemia includes energy metabolism disorders, platelet aggregation, vasoconstriction and microcirculation disorders, excitatory amino acid toxicity and so on, and the drugs clinically used for the preventing and treating cerebral ischemia are mainly antiplatelet drugs aspirin, ticlopidine and other drugs. Most cerebral ischemia patients need a long time of medication, but the side effect from long-term medication, drug prices, limitations of treatment course will affect the treatment of the disease (Atta et al, 2017, Halim et al, 2017). Chinese medicine believes that the occurrence of ischemic stroke relates with the Qi stagnation, Qi deficiency, phlegm turbidity, blood stasis, Yin deficiency, heat or Fire and other factors, so, clinically, some therapeutic principles like “tonifying Qi and reinforcing deficiency”, “activating blood and resolving stasis”, “clearing heat and expelling toxin” and others are adopted to prevent cerebral ischemic diseases.…”
