    Pectin Lab Report

    • 1863 Words
    • 8 Pages

    Dilution range was made between 2mg/ml-300mg/ml of pectin in deionized water. FeSO4 standard consisting of 0.2, 0.4, 0.6, 0.8 and 1mM in deionized water was used to plot a standard curve, the activity of pectin was determined relative to 1mM of the standard. The stock solutions include 300mM acetate buffer, pH 3.6, 10mM TPTZ (2, 4, 6-tripyridyl-S-triazine) solution in 40 mM HCl and 20 mM Fecl3.6H2O. The working solution was prepared fresh by mixing 25 ml acetate buffer, 2.5 ml TPTZ and 2.5 ml FeCl3.6H2O, and its temperature raised to 37ºC before use. 150µL of pectin solution was mixed with 2850µL of FRAP solution for 30 min in the dark condition. The absorbance of the reaction mixture (Ferrous-tripyridyltriazine complex) was read at 593 nm. The standard curve displayed a linear trend between 200 and 1000 µM Feso4. Results was expressed relative to µM (Fe…

    • 5 Pages

    Cerium is a rare earth element of the lanthanide series (atomic no. = 57– 71) of the periodic table. Among the various rare earth metals, cerium granted a hugeattention towards scientific community due to its catalytic antioxidant property. Usually, antioxidants protect cells from oxidative damage, mediated by ‘reactive oxygen species’ (ROS), which include free radicals such as superoxide anion (O2•-), hydroxyl radical (•OH), singlet oxygen (1O2) and non-free radical species like hydrogen…

    2.3.1.2 Antioxidant analysis Two methods to measure the antioxidant activity are by determining its ability of hydrogen atom donation to a reactive species and/or check its ability to take off any molecules of oxidative initiation. Total antioxidant capacity (TAC) level evaluation can be classified into a direct method and indirect method. Indirect method or in vitro method consists of DPPH radical scavenging activity assay, Trolox equivalent antioxidant capacity (TEAC) and oxygen radical…

    Purium Apothe-Cherry contains melatonin, and the tart concentrate is high is high in bioflavanoids content. Sour/tart cherries are nature’s most nutrient-dense food containing phytochemicals, antioxidants, and a high ORAC (Oxygen Radical Absorbance Capacity) value. It is recommended that Purium Apothe-Cherry should be taken with Aloe Vera to get a recipe that is super good to serve as a sleep cocktail. PROS • The melatonin content helps to balance circadian rhythms which are responsible for…

    (24 mg mL-1) was prepared and 2 mL of this solution were added to 50 μL of different concentrations of lycopene. After one-hour incubation at room temperature in the dark, absorbance at 517 nm was measured, using a spectrophotometer (Pharmacia LKB Novaspec, Sweden) (Aminzare, Aliakbarlu, and Tajik 2015). Scavenging capacity of lycopene was calculated as follows: (Radical Scavenging Activity) RSA% = [(Ablank - ASample ) / Ablank]×100 Free fatty acids (FFA)…

    • 38 Pages

    An essential ingredient to be utilized in the process is the Alamar Blue Cell Viability Reagent, which is known for its reducing function. The declining ability of a cell is directly proportional to the quantitative measure of its proliferation activity. In the context, determination of the reducing capacity of a given cell will play a critical role in the establishment of its relative cytotoxic activity. The analogy is based on the idea that cells maintain a reducing environment while in their…
