The poor water solubility of natural antioxidants restricts their bioavailability and therapeutic use. We aimed to develop a new phytosome formulation with active compounds from extracts ginger (GINex) rosehips (ROSAex) designed increase bioavailability, antioxidant anti-inflammatory properties. phytosomes (PHYTOGINROSA-PGR) were prepared freeze-dried GINex, ROSAex phosphatidylcholine (PC) in different mass ratios using the thin-layer hydration method. PGR was characterized for structure,...
Cancer is one of the leading causes mortality worldwide, and despite significant advances in treatment plans drug development, survival prospects are still low, side effects life altering. This article examines plant-derived extracts their therapeutic potential against various types hepatocellular carcinoma as a means inducing fewer compared to existing treatments. The focus on vitro synergistic effect silver bio-nanoparticles obtained from Clematis vitalba, Melissa officinalis, Taraxacum...
Background/Objectives: Cancer remains one of the leading causes mortality worldwide. Despite significant advancements in treatment strategies and drug development, survival rates remain low adverse effects conventional therapies severely impact patients’ quality life. This study evaluates therapeutic potential plant-derived extracts hepatocellular carcinoma treatment, with a focus on minimizing side while enhancing efficacy. Methods: research investigates vitro synergistic effect silver...
Abstract In this study, microwave assisted a hydrodistillation process (MWHD) of essential oils from lavender (Lavandula angustifolia Miller) was investigated. order to examine any potential differences in oil extraction, the flowers underwent enzymatic pretreatment. A 23 factorial design experiments, combined with statistical methods data analysis were used optimize pretreatment and evaluate influence major variables (enzyme concentration, temperature pH) on performance extraction. Under...
Green chemistry is a pharmaceutical industry tool, which, when implemented correctly, can lead to minimization in resource consumption and waste. An aqueous extract of Salix alba L. was employed for the efficient rapid synthesis silver/gold particle nanostructures via an inexpensive, nontoxic eco-friendly procedure. The nanoparticles were physicochemically characterized using ultraviolet-visible spectroscopy (UV-Vis), Fourier transform infrared (FT-IR), dynamic light scattering (DLS), X-ray...
A study was conducted to investigate the organic compounds residues in different types of coffee from market Romania.High pressure liquid chromatography with fluorescence detector (HPLC), respectively gas electron capture detection (GC-ECD) used for determination 7 polycyclic aromatic hydrocarbons (PAHs) and 9 organochlorine pesticides (OCPs) samples.It found that concentrations PAHs samples varied 0.001 µg/Kg 90.732 µg/Kg.B[a]P absent green samples.The limits ranged 0.02 ng/kg 0.04...
Abstract Collagen is one of the predominant proteins found in all multicellular animals. In this paper, performance ultrafiltration process (UF) for concentrating collagen protein was studied by performing batch experiments using a membrane module with an effective area 28 cm 2 and equipped regenerated cellulose molecular weight cut‐off 5 kDa. The feed solution consisted aqueous solutions bovine hydrolysate 10 effects concentration (1%, 2%, 3%, 4%, 5%) on were determined. optimum operating...
Essential oils were obtained from different parts of Agastache foeniculum (Lophanthus anisatus) plants by means extraction: green extraction using hydro-distillation (HD) and bio-solvent distillation, BiAD, discontinuous supercritical fluid extraction, in two stages: (1) with CO2, (2) CO2 ethanol co-solvent. The yields determined. yield values varied for the plant, as well method extraction. Thus, they had 0.62 ± 0.020 0.92 0.015 g/100 g samples whole aerial 0.75 0.008 1.06 0.005 leaves,...
Gold nanoparticles are considered the newest drug carriers for different diseases. Therefore it is appropriate continuous optimization of their preparation. In this study, gold colloids with an average size 1 - 26 nm were obtained by reduction tetrachloroauric acid trisodium citrate. The nanomaterials characterized UV-Vis spectroscopy and dynamic light scattering technique. addition, zeta potential was measured samples synthesized in order to determine stability colloids. A Two-level Full...
Abstract Slow-release microencapsulated N, P, and K fertilizer synthesis was optimized the products exhaustively characterized. Four NPK formulations with nutrient mass ratios of 1:0:0, 1:1:0, 1:1:1, 2:1:1 were characterized following European Council Regulation 2003/2003 for fertilizers as well ICP-AES, 1H-NMR, FT-IR, HPLC, elemental analysis, XPS, SEM, dynamic light scattering, thermogravimetry, differential activity index, leaching rate. These have good slow-release properties decrease...
The fate of organochlorine compounds in soil ecosystem is shaped by their physical-chemical properties and environmental conditions. high persistence polychlorobiphenyls (PCBs) given a slow degradation which varies from months to years (the half-life PCB 28 10.9 years, 52, 11.2 years). Due lipophilicity, these carcinogenic can be easily uptaken plants transferred the food chain. widespread use medicinal plant, Mentha Piperita, pharmaceutical industry represents risk contamination pollution....
A design of experiment (DoE) approach is presented for the optimization Alendronate-hydroxyapatite nanoparticles� synthesis. The synthesis was performed using chemical precipitation technique from calcium nitrate, diammonium hydrogen phosphate and alendronate. Synthesis temperature, reactant addition rate ripening time were chosen as most relevant experimental factors our Design Experiments used in order to measure these conclusive process parameters their effect on controlling some final...
The purpose of this study was to produce additional data for the valorization process vegetable waste originating from dietary supplement technology. Two types different technological processes sea buckthorn oil were used: organic solvent extraction (P1) and cold (P2). Batch experiments evaluated influence pH, initial metal concentration, contact time, Langmuir Freundlich adsorption isotherms. following pollutants—Cu, Cr, Co, Ni, Pb Zn—from wastewater studied. removal efficiency metals at pH...
