Overuse of artificial chemical fertilizers could be detrimental to the environment. Utilizing beneficial microorganisms as biofertilizers is a sustainable technique that promotes soil health, crop yield, and ecosystem preservation. Curcuma longa L. is utilized as a medication since it has its antibacterial, anti-microbial, and anti-tumor characteri...
Pharmacokinetics and tissue distribution of LN002, a new compound alternative oxidase inhibitor against Cryptosporidium ...
Published in Frontiers in Pharmacology
Cryptosporidiosis is considered a crucial zoonotic disease caused by widely distributing parasitic protozoa called Cryptosporidium spp. Nitazoxanide is the only FDA-approved drug but is only effective with a good immune response of the host. In addressing this unmet medical need, we previously identified a compound, namely, LN002, as a potent alter...
Chap 17. Quantification of Secondary Lipid Oxidation Products in Oils, Fats, and Food Products: Malondialdehyde by HPLC-...
This chapter presents an accurate method to prepare, analyze, and quantify secondary lipid oxidation products namely malonaldehyde MDA (as MDA-(TBA)2) and TBA reactive substances (TBA-RS). Each step of the extraction of the targeted compounds, preparation of MDA standard, external calibration, and finally analysis of the reaction media are presente...
Chap 10. Quantification of Tocopherols and Tocotrienols (Tocols) in Oils, Fats, and Food Products by HPLC Fluorescence
Tocopherols and to a lesser extent tocotrienols were widely present in food from animal and vegetable origin. Some of these compounds exhibited a vitamin E activity and played a major action in the cell antioxidant defence system and as antioxidants per se in foods. Tocols were mainly present in the human diet. Thus, accurate quantification of toco...
Exploratory evaluation supported by experimental and modeling approaches of Inula viscosa root extract as a potent corro...

Published in Open Life Sciences
The corrosion of metals poses a threat to the economy, the environment, and human health due to undesirable reactions and contaminated products. Corrosion inhibitors, including natural products, can play a key role in protecting metallic materials, especially under challenging conditions. In this study, the roots of the Inula viscosa plant were exa...
Insights into the stereoisomerism of dihydroquercetin: analytical and pharmacological aspects
Published in Frontiers in Chemistry
Dihydroquercetin (DHQ) is a representative of flavonoids that is available on the market as a food supplement and registered as an active pharmaceutical ingredient. The structure of this compound is characterized by the presence of two chiral centers in positions 2 and 3 of the pyranone ring. Current regulatory documentation on DHQ lacks quantitati...
Separation and Identification of some Phenolic and Alkaloid Compounds from the Leaves and Flowers of Lantana camara Linn...
Published in IOP Conference Series: Earth and Environmental Science
This study included two paths: the first was to extract the active compounds from the leaves and flowers of Lantana camara L. using a Soxhleet device, and then to conduct the hydrolysis acid process for the methanolic extract to separate the phenolic compounds. The alkaloid compounds were also separated from the methanolic extract and diagnosed wit...
