Performance characteristics of bioassay, UV-spectrophotometry and high performance liquid chromatographic determination of sparfloxacin in tablets
(2001-01-01)
The microbiological bioassay, the UV-spectrophotometry and the high performance liquid chromatography (HPLC) methods for assaying sparfloxacin in tablets were compared. The accuracy, repeatability, and precision of each ...
Implementation of an in vitro bioassay as an indicator of the bionutrient FitoMas E
(Pontificia Universidad Católica de Chile. Facultad de Agronomía e Ingeniería Forestal, 2011)
Chronic toxicity bioassay with populations of the crustacean Artemia salina exposed to the organophosphate diazinon
(Society of Biology of Chile, 2010)
A chronic toxicity bioassay was conducted with the microcrustacean Artemia salina as the testing organism for the toxic organophosphate diazinon in order to determine if the species is an appropriate indicator of pollution ...
Performance characteristics of high performance liquid chromatography, first order derivative UV spectrophotometry and bioassay for fluconazole determination in capsules
(Sociedade Brasileira de Química, 2012-01-01)
The bioassay, first order derivative UV spectrophotometry and chromatographic methods for assaying fluconazole capsules were compared. They have shown great advantages over the earlier published methods. Using the first ...
Stability study of fluconazole applying validated bioassay and stability-indicating LC methods
(2011)
Chemical degradation of drugs may result in altered therapeutic efficacy and even toxic effects. Therefore, understanding the factors that change the stability of pharmaceuticals and identifying ways to guarantee their ...
Standardization of bioassays for monitoring resistance to insecticides in Aedes aegypti
(2005-12-01)
Since the reintroduction of Aedes aegypti in Brazil in the 1980s, insecticide use for its control is routine. The chemical control efficacy is threatened by vectors developing resistance to insecticides. The World Health ...
Chronic toxicity bioassay with populations of the crustacean Artemia salina exposed to the organophosphate diazinon
(Sociedad de Biología de Chile, 2010)
Bakuchiol derivatives from the leaves of Psoralea glandulosa
(Elsevier Ltd, 1996)
Four new meroterpene derivatives have been isolated in a bioassay- guided study of the methanol extract of the leaves of Psoralea glandulosa, in addition to the known compounds bakuchiol and angelicin. Structures for the ...
