Physicochemical, Phytochemical Evaluation and Pharmacological Investigation of Roystonea regia
Research Journal of Pharmacy and Technology, 2023Natural products are always been the great source of therapeutic agents. The aim of the study was to analyze the physicochemical properties of Roystonea regia plant which were performed on its powder. All the results were in their official limits. Extraction was done with n-hexane, chloroform and ethanol using Soxhlet apparatus and phytochemicals of ...

Structural organization in palm stems of Roystonea regia and Archontophoenix alexandrae
IAWA Journal, 2020Abstract Having a high stature subjects palms to the same constraints as trees, but the lack of cambial growth urges them to adopt a different strategy. We aimed to characterize the spatial organization of xylem tissues and their potential functions in two palm stems: a 30 cm diameter at breast height (DBH) royal palm (Roystonea regia) and a 12 cm DBH ...

Roystonea regia a monocotyledonous tree, bears rhizobial root nodules
Folia Microbiologica, 1997The first instance of a monocotyledonous treeRoystonea regia (royal palm) bearing root nodules is reported. They are formed by a Gram-negative bacterium which was tentatively identified asRhizobium sp. The nodules are formed on younger roots of the tree mostly in the rainy season. Younger plants also become nodulated.

Applied Science and Engineering Progress, 2023
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 ...

A Potyvirus Isolated From Cuban Royal Palm (Roystonea Regia) in Queensland.
Australasian Plant Pathology, 1993Chlorotic ringspot symptoms were noted on Cuban royal palms (Roystonea regia) from two locations in south-east Queensland. A virus, provisionally named Roystonea palm virus (RoPV), was isolated from these plants. It was mechanically transmitted to Chenopodium amaranticolor, C. quinoa, Nicotiana benthamiana, N.

Oral Subchronic Toxicity of a Lipid Extract fromRoystonea regiaFruits in Mice
Drug and Chemical Toxicology, 2008D-004 is a lipid extract of royal palm (Rosytonea regia) fruits that prevents prostate hyperplasia induced with testosterone in rodents. Previous studies have shown no D-004-related toxicity in rats, but no study in mice had been reported. D-004 (500, 1000, and 2000 mg/kg) was evaluated in a subchronic (eight weeks) study in NMRI mice.

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
