Hibiscus Rosasinensis L. extract mediated biosynthesis of Pd nanoparticles (NPs) and their deposition on the magnetic calcium lignosulfonate (MCaLig), as a simple and eco-friendly process for the preparation of Pd NPs@FeO-lignin, is reported. The Pd NPs@FeO-lignin was characterized by TEM, XRD, EDS, FE-SEM, FT-IR, VSM, and UV-Vis. The magnetic NPs were employed as exceptional catalysts in the catalytic reduction of Cr(VI) and Suzuki-Miyaura reaction between PhB(OH) and substituted aryl halides in Et
HO as well as under ligand free conditions in the presence of KCO with satisfactory product yields. Regeneration of the Pd NPs@FeO-lignin was carried out by a magnet after the preparation of biphenyls. Catalytic efficiency retention was achieved after seven cycles.

Lignin is one of the most promising renewable sources for aromatic hydrocarbons, while effective depolymerization towards its constituent monomers is a particular challenge because of the structural c...
Lignin from kenaf (Hibiscus cannabinus) core was investigated as an alternative filler for rubber. Three types of extraction methods were used to isolate lignin from kenaf, namely kraft, soda and orga...
Lignin valorization has risen as a promising pathway to supplant the use of petrochemicals for chemical commodities and fuels. However, the challenges of separating and breaking down lignin from ligno...
Lignin holds tremendous potential as a renewable feedstock for upgrading to a number of high-value chemicals and products that are derived from the petroleum industry at present. Since lignin makes up...
In this paper, magnetic polyethyleneimine lignin (M-Lignin-PEI) was prepared by a reversed-phase suspension crosslinking method to remove Pb (II) form aqueous solutions. SEM, FT-IR, TGA, XRD and VSM t...

The purpose of this study is to determine the effect of Aqueous mushroom extract (AME) on intra ocular pressure (IOP) in humans or as a potential anti glaucoma drug.
Hypertension, also known as high blood pressure, is a very common disease and is considered "the silent killer". Hypertension is responsible for at least 45% of deaths due to heart disease...
Periodontal diseases and caries are essentially initiated and progressed by accumulation of dental plaque. Thus, daily effective plaque control is valuable as a preventive measure and main...
Determine if a double-blind, randomized, placebo-controlled clinical intervention, based on a dietetic intervention and physical exercise, supplemented with a polyphenolic extract, decreas...
The most abundant natural aromatic organic polymer found in all vascular plants. Lignin together with cellulose and hemicellulose are the major cell wall components of the fibers of all wood and grass species. Lignin is composed of coniferyl, p-coumaryl, and sinapyl alcohols in varying ratios in different plant species. (From Merck Index, 11th ed)
A plant genus of the family ASTERACEAE. The common name of thoroughwort is also used for other plants including EUPATORIUM; CHROMOLAENA, Hebeclinium and Koanophyllon. Eupolin is the aqueous extract of the leaves.
A copper-containing oxidoreductase enzyme that catalyzes the oxidation of 4-benzenediol to 4-benzosemiquinone. It also has activity towards a variety of O-quinols and P-quinols. It primarily found in FUNGI and is involved in LIGNIN degradation, pigment biosynthesis and detoxification of lignin-derived products.
A dehydrated extract of thyroid glands. After the removal of fat and connective tissue, the extract is dried or lyophilized to yield a yellowish to buff-colored amorphous powder containing 0.17-0.23% of iodine.
A plant genus of the family RANUNCULACEAE. Members contain hellebrin (BUFANOLIDES). The extract is the basis of Biocil preparation used for rheumatism.
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
