Study on microbial diversity in the unexplored rhizosphere is important to understand their community structure, biology and ecological interaction with the host plant. This research assessed the genetic and functional diversity of fluorescent pseudomonads [FP] in the green gram rhizophere. One hundred and twenty types of morphologically distinct fluorescent pseudomonads were isolated during ve...

Background and Objectives: Roselle (Hibiscus sabdariffa L.) is one of the valuable plants grown in tropical and subtropical regions such as some parts of Iran. Roselle calyces are commonly used to make  herbal tea as well as a natural food color additive. However, Roselle seeds are usually discarded as by–products, while they can be used as a source of nutritious and functional compo...

The aim of this study is to compare the metallic and natural fiber reinforced polymer composite bone plates used in humerus fractures. A 3D finite element model was developed to analyze the performance of both types of plates. This study proposed on fabrication of natural fiber powdered material (like Sisal (Agave sisalana), Banana (Musa sapientum) and Roselle (Hibiscus sabdariffa)) Reinforced ...

Abstract Background Studies of plant extract-mediated synthesis nanoparticles is extensively explored and studied in recent time due to eco-friendly, cost-effectiveness minimal use toxic chemicals for synthesis. In this study, the Ag–TiO 2 nanocomposites (NCs) was carried out using Origanum majorana leaf extract under ultrasound irradiation. plays an important role as reducing capping agent (NC...

Supercritical carbon dioxide (SC-CO2) is a clean and green technology for extracting polyphenols antioxidants from roselle (Hibiscus Sabdariffa) as nutraceutical ingredients high-value co-products development. To increase the SC-CO2 fluid affinity towards polar compounds, general regard safe (GRAS) solvent, ethanol-water was added in small amount modifier. Dry calyces were extracted using modif...

Natural colorants have been widely used in food and cosmetic products. Nonionic and anionic surfactants are also usually added as solubilizers and stabilizers in the products. Surfactants form a special structure, a so-called micelle. Micelles can alter stabilities and physicochemical properties of other chemicals in the system. The objectives of this study were to determine stabilities in mice...

The aim of this research was to extract phenolic compounds from defatted Roselle (Hibiscus sabdariffa L.) seed and assess their antioxidant potential. Water, ethanol (30%), methanol (30%) and acetone (30%) were used as solvent for extraction. The proximate composition, total phenolic content and extraction yield were analyzed. Antioxidant efficacies of Roselle seed extract were tested by using ...

Integrated nutrient management (INM) is a holistic approach that involves the application of organic and inorganic fertilizers to improve soil health crop productivity. The research study was conducted demonstrate effective use INM on in Green gram. We used randomized block design (RBD) with four levels poultry manure @ 0, 50, 75 100% ha-1, nitrogen, phosphorous potassium@ ha-1 rhizobium seed t...

Introduction: Liver damage due N-diethylnitrosamine (DEN) is a global health challenge. The aim of this study was to assess the efficacy roselle (Hibiscus sabdariffa L.) calyces’ water-extract as Hepatoprotective material against liver induced by DEN in rats. Material and methods: Twenty-five (25) adult female albino Wistar rats were grouped randomly into five groups (Gs): G1, Normal healthy an...

In recent years, green synthesis of nanoparticles has attracted a great attention because of medicine and biological applications. In this work, bismuth oxide nanoparticles (Bi2O3 NP) was prepared via green synthesis using mentha pulegium aqueous extract after 24 h at 90°C. The product was characterized by ultraviolet-visible (UV-VIS) spectrophotometer, Fourier transform infrared (FTIR), X-ray ...
