Abstract A rapid, simple, convenient, and widely applicable method for the direct fluorescent detection of organothiophosphorus pesticides and some postulated breakdown products of these compounds is presented. The coinpounds were spotted on thin layer chromatographic sheets, developed in ethyl acetate :nhexane, and made visible by exposure to bromine vapor followed by spraying with ferric chloride and 2-(o-hydroxy phenyl) benzoxazole. Of the 47 compounds tested, 32 compounds produced fluorescent blue spots vinder longwave ultraviolet light; these consisted of 25 organothiophosphorus pesticides, 5 sulfur-containing breakdown products, and phosphoric and hypophosphorous acids. A superimposed Congo red spray destroyed the fluorescence and resulted in dark blue spots against a red backgrovind. The sensitivity of this method is in the range of 0.2 to 5.0 μg, depending on the specific compound.

This study aims to obtain the profile of Thin-Layer Chromatography (TLC) and Ultraviolet-Visible (UV-Vis) spectrophotometry from ethanol extract of akar kuning stems (Arcangelisia flava) from Central Kalimantan. The TLC method is used with the orientation phase of the combination of polar-non-polar solvents resulting from orientation, while ethanol is used as the solvent for UV-Vis spectrophotometers. TLC results showed the formation of 3 stains on a combination of polar solvents chloroform : methanol : water while in a non-polar solvent combination n-hexane : ethyl acetate did not show any stains. Comparison of retention factor (Rf) values show the best combination of polar solvents to separate stains at a ratio of 5 : 2 : 1, respectively. Separation in 2-dimensional TLC with polar solvents showed a similar pattern with 1-dimensional separation in the form of 3 stains. UV-Vis spectrophotometer results showed 4 main peaks with wavelength 227.2; 267.4; 345.2; and 425.3 nm, respectively. The profile of the peak formed is very similar to that shown by berberine, one of the main metabolites of akar kuning. TLC and UV-Vis spectrophotometers profiles obtained are expected to support further research using akar kuning stems, especially those from Central Kalimantan.

Blooms of the marine flagellate Chrysochromulina have resulted in mortality of marine organisms in Scandinavian waters, including fish in aquaculture. Eight species of Chrysochromulina, namely C. apheles, C. brevifilum, C. ericina, C. hirta, C. leadbeateri, C. parva, C. polylepis, and C. simplex, isolated into unialgal culture, were examined for haemolytic activity and toxicity to the brine shrimp, Artemia salina. Haemolytic fractions were obtained from all species, but only C. polylepis cells were toxic to Artemia. Thin-layer chromatography (TLC) analysis in chloroform –methanol–water (75:25:4) and in chloroform–methanol (9:1) yielded up to six haemolytic spots. Except for one spot, these all occurred in extracts of the species examined, including Isochrysis sp., which was used as a control, C. polylepis, and the well-known fish killer Prymnesium parvum. The single unique haemolytic spot (Rf values 0.45 and 0.16 in solvents I and II, respectively) occurred in the extract from C. polylepis. When isolated by TLC, the contents of the single spot were toxic to Artemia. Key words: Chrysochromulina, toxicity, haemolytic, Artemia, thin-layer chromatography (TLC).
