Identification of betanin degradation products
Zeitschrift f�r Lebensmittel-Untersuchung und -Forschung, 1983Betanin in solution, upon heating, was found to hydrolyze to betalamic acid and cyclodopa-5-O-glycoside. This reaction was monitored by an analytical high performance liquid chromatography (HPLC) method. The products were isolated by preparative reversed-phase HPLC or column chromatography using anion-exchange resins.

Degradation Products of Chloramphenicol
Journal of Pharmaceutical Sciences, 1971Incubated aqueous solutions of chloramphenicol at various pH's (1-14) yielded detectable amounts of p-nitrobenzaldehyde (an oxidation product) and arylamine (a reduction product). Identical degradation products were also found in certain dosage forms (creams and capsules), although they were not found in ophthalmic ointment.

Alkaline Degradation Product of Cephradine
Journal of Pharmaceutical Sciences, 1973Abstract Cephradine yields an unique alkaline degradation product, which has been identified by proton magnetic resonance, n C-N.MR, and mass spectrometry as 2-[6-(l,4-cyclohexadine-l- yl) - 2,5 - dioxo - 3 - piperazinyl] - 5,6- dihydro - 5 - methyl - 2//-1.3- thiazine-4-carboxylic acid, sodium salt.

Degradation of Fibronectin Fibrils by Matrilysin and Characterization of the Degradation Products
Experimental Cell Research, 1995Matrilysin is a metalloproteinase expressed in a variety of tumors as well as in some types of normal tissue. In addition to regulating normal tissue remodelling, metalloproteinases are believed to play a role in tumor cell invasion and metastasis by degrading components of the extracellular matrix, for example the highly insoluble fibronectin fibrils ...

Degradation of polyribonucleotides: Biocatalysis and the monitoring of products
Applied Biochemistry and Microbiology, 2014Macroporous monolithic material containing covalently linked ribonuclease A was used to create high-performance flow heterogeneous biocatalysts (bioreactors). The kinetic parameters of the degradation of polycytidylic acid were identified, and the properties of the obtained systems were compared. A HPLC method has been developed for monitoring products

Food production and environmental degradation
2019Despite its considerable environmental impact, food production has not been regarded seriously as a cause of environmental degradation. This paper examines the impact of food production on the environment and discusses some of the known methods for limiting detrimental effects of cropping.

Photochemical degradation products of pentachlorophenol
1969For the control of barnyard grass, Panicum crusgalli L., on the paddy fields in Japan, farmers utilize the herbicide, PCP-Na (sodium pentachlorophenoxide) on about the fifth day after transplanting of rice plant seedlings. On the day of the treatment the paddy field water is highly toxic to fish and many injuries by PCP herbicides to fish cultures ...

Degradation products of lignin
1936A method of increasing the yield of methanol lignin was devised in collaboration with Mr. J. Swartz. Some of the methoxyl groups of completely methylated methanol lignin were shown to be probably anolic in nature. Catalytic reduction of this material, using two of the more recently developed catalysts, Was attempted, the results obtained being entirely
