| Abstract:
The purpose of the present study was to determine the presence of measurable amount of endogenous formaldehyde (HCHO) in callus tissue cultures of Datura innoxia Mill. applying different analytical methods. The effect of HCHO deprivation with dimedone - as abiotic stress - was also investigated on the growth and endogenous HCHO level in D. innoxia callus cultures. In our work, HCHO in dimedone adduct form (formaldemethone), has been isolated and characterised by overpressured layer chromatography (OPLC), high pressure liquid chromatography (HPLC), and matrix assisted laser desorption / ionization mass spectrometry (MALDI MS). Endogenous HCHO deprivation with dimedone affected the cell proliferation in D. innoxia callus tissues as well. | |
