Rapid, precise, accurate, and specific ratiospectra derivative spectrophotometry and a simple UV spectrophotometry using simultaneous equation methods are developed for the simultaneous determination of bisoprolol fumarate and hydrochlorothiazide from combined pharmaceutical dosage forms. For ratiospectra derivative spectrophotometry, the amplitudes were measured at 202.6 nm for bisoprolol fuma...

Peels of Hijau lumut banana (HLB) (Musa paradisiaca L.) are a form organic waste that has not been widely utilized. This study was conducted to determine the antibacterial activity ethyl acetate extract HLB peels and their nanoparticles at various concentrations chitosan against Staphylococcus aureus Escherichia coli. It also aimed characterize most active nanoparticles. Ex...

To investigate the antioxidant activity and antibacterial of Vernonia cumingiana Benth, in this study, spectrophotometry assays were used to determine indexes vitro, including 1,1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging capacity total capacity, aiming understand its pharmacodynamic components. The results showed that different component extracts had high DPPH ability highest ...

In this work, a clean and simple magnetic solid-phase microextraction based on L-arginine modified dialdehyde starch nanocomposite was developed for the preconcentration determination of diclofenac in biological samples by UV–Vis Spectrophotometry. A Plackett–Burman experimental design used to evaluate influence effective parameters. Significant parameters were further optimized Central Composi...

The paper presents an examination of the possibility applying raspberry flower extract (Rubus idaeus L.) as a green inhibitor general corrosion copper in 3% NaCl. Raspberry flowers sort Polka were collected from Moševac near Maglaj city, Bosnia and Herzegovina. ethanol was obtained by ultrasonic extraction. A significant content polyphenol found UV/VIS spectrophotometry analysis. Results DC tec...

Sonchus arvensis, known as sowthistle, belongs to Asteraceae and contains numerous phenolic acids flavonoids that exhibit antioxidants. The type of extraction solvent will affect biological activity level, resulting in different metabolite profiles metabolomics approaches can evaluate by fingerprint analysis using FTIR spectrophotometry UHPLC-Q-Orbitrap HRMS. Furthermore, the spectra profile HR...

there are various methods for the analysis of potassium sorbate and sodium benzoate in food products, but a rapid and reliable method for identification of these preservatives in doogh (an iranian traditional dairy drink) is a procedure, in which high performance liquid chromatography (hplc) utilized and followed by uv diode array detection of the two preservatives. the aim of this case study w...

This paper provides preliminary data on the use of three different mechanical procedures to remove lichen Diploschistes scruposus and a gypsum black crust from an ornamental granite. The methods used were wet sandblasting (Hydrogommage®), dry (IBIX®) dry-ice blasting. In addition, lichens also removed by scraping with scalpel. cleaning efficacy undesirable effects granite evaluated stereomicros...
