Beneficial effects of ammonium hydroxide was studied, to optimize the ammonium hydroxide concentration for effective tenderization of spent hen meat. Spent hen meat chunks were subjected to ammonium hydroxide treatment (AHT) at different concentrations (0%, 0.1%, 0.5% and 1.0% v/w) and evaluated for different quality parameters after 24 hours. The results indicated a significant increase in pH,...

In recent years, there has been a growing interest in green solvents to dissolve and shape cellulose into microspheres. However, development of suitable for room temperature dissolution shaping spheres is very limited. this work, novel process fabricate microspheres presented. First, the effect ethanol-hydrochloric acid pulp pretreatment on solubility aqueous tetra-n‑butyl phosphonium hydroxide...

Rifampisin merupakan salah satu obat anti-tuberkulosis. HPLC metode pilihan karena kepekaan, reprodusibilitas dan spesifitasnya. Namun terbaru dari kromatografi cair membutuhkan penambahan tetra-butyl ammonium hydroxide yang dapat memperpendek umur kolom. Penelitian ini bertujuan untuk mengembangkan suatu dengan waktu pengerjaan efisien dibandingkan metode-metode sebelumnya. Sistem yaitu Allian...

CsA, bovine serum albumin, and β-nicotinamide adenine dinucleotide 2’-phosphate reduced tetrasodium salt hydrate (NADPH), were purchased from Sigma-Aldrich (St. Louis, MO). Cyclosporine D (internal standard for clinical study) and cyclosporine B (internal standard for in vitro study) were purchased from LKT Laboratories (St. Paul, MN). The CsA metabolites used for calibration curves and quality...

The nature of solvent-biomolecule interactions is generally weak and non-specific. The addition of ionic liquids (ILs), which have emerged as a new class of solvents, strengthen the stability of some proteins whereas the same ILs weaken the stability of some other proteins. Although ILs are commonly used for the stabilization of biomolecules, the bimolecular interactions of their stabilization-...

Restacked niobate nanosheets were prepared by exfoliation of the corresponding Dion–Jacobson type layered perovskites (HCa2Nb3O10, HSr2Nb3O10 and HLaNb2O7) with tetra(n-butyl)ammonium hydroxide and subsequent treatment with hydrochloric acid. The nanosheets were characterized by means of X-ray diffraction, scanning electron microscopy, Raman spectroscopy, and diffuse reflectance spectroscopy. W...

A simple, sensitive and rapid ionpair high performance liquid chromatographic methodwas developed for the estimation ceftriaxone sodium (CS) and tazobactum sodium (TS) in pharmaceutical dosage forms. Lichrocart100-RP18e5μm-C18 column was used with a mobile phase containing mixture of 0.012M tetra butyl ammonium hydroxide in 0.01M potassium dihydrogen phosphate : acetonitrile in the ratio of 70:...

Tert-butyl carbazate (1) reacted with ammonium thiocyanate and phenyl isothiocyanate to afford the corresponding 5-tert-butoxy-4H-1, 2, 4-triazole-3-thiol (3) 5-tert-butoxy-4-phenyl-2H1, 2, 4-triazole-3(4H)-thione 5 respectively. Compound (1) also reacted with carbon disulfide and potassium hydroxide to afford 5-tert-butoxy-1, 3, 4-oxadiazole-2(3H)-thione 6. Treatment of 6 with methyl iodide, 2...
