Urease is a nickel-dependent amidohydrolase that catalyses the decomposition of urea into carbamate and ammonia, reaction constitutes an important source nitrogen for bacteria, fungi plants. It recognized as potential antimicrobial target with impact on medicine, agriculture, environment. The list possible urease inhibitors continuously increasing, special interest in those interact block flexible active site flap. We show disulfiram inhibits Citrullus vulgaris (CVU), following...

Phosphomolybdic and phosphotungstic acids mixture, known as Folin-Ciocalteu reactive, is one of the main methods for quantification polyphenolic compounds in vegetable extracts (FC reactive). However, other spectrophotometric methods, it can be unspecific interact with molecules, such sugars, present extracts, modifying obtained results. The aim study was to evaluate effect glucose, sucrose, fructose, xylose, mannose, rhamnose arabinose on by FC method. Fructose xylose showed highest...

The wheat flour tortilla (WFT) is a Mexican food product widely consumed in the world, despite lacking fiber and micronutrients. Ramón seed (RSF) an underutilized natural resource rich fiber, minerals bioactive compounds that can be used to improve properties of starchy foods, such as WFT. study evaluated impact partial replacement with RSF on physicochemical, sensory, rheological nutritional antioxidant capacity (AC) RSF-containing (RFT). Results indicated RFT (25% RSF) had higher dietary...

Semen cryopreservation damages sperm due to oxidative stress. This study evaluated the antioxidant capacity of Moringa oleifera seed extract in cryopreserved ram semen and impact on characteristics. from eight hair rams (four per sampling) was allocated into four groups, according their treatment prior cryopreservation: Control (no extract), 0.5 (M0.5), 5.0 (M5.0), 10.0 (M10) mg/mL M. extract. The activity (ferric reducing power, FRAP) spermatic characteristics (sperm viability; progressive...

Lycopene and oleoresin extraction from powder of tomato over-ripe by three agitation methods four solvents have been evaluated. Also, the oleoresins were characterized biochemically. On average, moisture content was found to be 4.30, ash 8.90, proteins 11.23 lipids 4.35 g 100 g−1. The best yield achieved combining sonication acetone at 1.43 greatest amount lycopene (65.57 ± 0.33 mg g−1) also obtained using same treatment. presence trans-lycopene positively confirmed HPLC FTIR. In oleoresins,...

The effect of four elicitors on phytochemical content in two varieties lettuce was evaluated. best preharvest day for application each elicitor chosen. Solutions arachidonic acid (AA), salicylic (SA), methyl jasmonate (MJ), and Harpin protein (HP) were applied by foliar aspersion leaves while cultivating under hydroponic conditions. Application done at 15, 7, 5, 3, or 1 before harvest. Green showed the highest increase when (AA, SA, HP) 7 Similarly, antioxidant activity rose all treatments...

Background: Hibiscus (Hibiscus sabdariffa L.) is a flowering plant gaining interest for its potential health benefits due to high content of phenolic compounds and antioxidant properties. These properties have been linked various improvements, including reduced risk chronic diseases.
