Peroxidase from leaves of royal palm tree Roystonea regia: purification and some properties
Plant Science, 2001Abstract Screening of tropical plants demonstrated high peroxidase activity in leaves of some species of palms. Using the leaves of royal palm Roystonea regia as a source, the peroxidase has been isolated to homogeneity. The enzyme purification steps included homogenization, (NH 4 ) 2 SO 4 precipitation, extraction of palm leaf colored compounds ...

This study investigated the properties of hybrid composites made from Roystonea-Regia and banana fibers for potential applications in industries requiring lightweight, environmentally favorable, and mechanically strong materials. The analysis of density and void fraction revealed that the addition of banana fibers increased the composite's density ...

Unveiling root nodulation in Tribulus terrestris and Roystonea regia via metagenomics analysis
Molecular Genetics and GenomicsRoot nodule symbiosis is traditionally recognized in the Fabales, Fagales, Cucurbitales, and Rosales orders within the Rosid I clade of angiosperms. However, ambiguous root nodule formation has been reported in Zygophyllaceae and Roystonea regia (Arecaceae), although a detailed analysis has yet to be conducted.

Roystonea regia and Ptychosperma macarthurii are exotic palm species widely grown in Nigeria as ornamentals. The kernels of R. regia and P. macarthurii were subjected to amino acids, fatty acids, and mineral elements analyses in this study. Glutamic acid (13. 64 and 14.00 g/100 g), aspartic acid (9.72 and 9.50 g/100 g), arginine (8.68 and 7.49 g/100 g),

The Effect of Alkali Treatment on Dielectric Properties ofRoystonea regia/Epoxy Composites
International Journal of Polymer Analysis and Characterization, 2011The present study investigates the electrical conductivity and dielectric properties of untreated and alkali-treated Roystonea regia natural fiber–reinforced epoxy composites at different frequencies along with compression and water absorption properties. Fiber was treated with 5% NaOH and characterized by chemical, thermogravimetric, tensile test, and

One year oral Toxicity of D-004, a lipid extract from Roystonea regia fruits, in Sprague Dawley rats
Food and Chemical Toxicology, 2010D-004, a lipid extract of royal palm (Roystonea regia) fruits that contains a reproducible mixture of fatty acids, has been shown to prevent testosterone and phenylephrine-induced prostate hyperplasia in rodents. This study investigated the long-term oral toxicity of D-004 in rats.

Indole acetic acid and its metabolism in root nodules of a monocotyledonous tree Roystonea regia.
Current microbiology, 1998A monocotyledonous tree, Roystonea regia, was found to bear root nodules. The root nodules contained a high amount (16.9 microg/g fresh mass) of indole acetic acid (IAA). A big tryptophan pool (1555.1 microg/g fresh mass) was found in the root nodules, which might serve as a source of IAA production. The presence of IAA-metabolizing enzymes IAA oxidase
