Ia. Sizova et al., QUANTITATIVE-DETERMINATION OF THE HERBICIDE BIALAPHOS IN FERMENTATIONBROTH BY TLC WITH SCANNING DENSITOMETRY, JPC. Journal of planar chromatography, modern TLC, 8(6), 1995, pp. 460-462
TLC on Sorbfil plates has been used to separate the herbicide bialapho
s from by-products (other amino acids, peptides, and pigments) in the
broth used for culture of Streptomyces hygroscopicus. Dipping in 0.3%
ninhydrin solution was used for visualization and subsequent quantitat
ion. High speed scanning densitometry and high performance liquid chro
matography have been used for quantitation and the results compared. C
oefficients of variation were <5.0%.
