✦ Synopsis

The residues and metabolism of radio-labeled cyromazine ( Ncyclopropyl-l,3,5-triazine-2,4,6-triamine) formulated as a 750 g kg-' WP ('Trigard' 75WP)@ was studied in greenhouse tomatoes. Residues of cyromazine and its metabolites were remarkably persistent, with only a slight loss occurring within a 30-day period. Findings with tomatoes were similar to those with glass plates when exposed to cyromazine. Little volatilization occurred from either tomato or glass surfaces kept under greenhouse conditions. The only metabolite identified was melamine on both glass plates and tomatoes. Two other metabolites were found but were not identified.

Shikonin is one of the active components isolated from the root of Arnebia euchrona (Royle) Johnst. It has been shown to possess significant antibacterial, antiinflammatory and antitumour activities and has been used clinically.

Two maturity stages of commercially grown tomatoes (breaker and mature green) were exposed to ethanol vapour (2 ml ethanol kg À1 fruit) for 6 h at 20 °C prior to storage at 5 °C and 20 °C. During storage the colour, ®rmness and composition changes were examined every 3 and 7 days. The results showed

Fluoroacetate and its toxic metabolite fluorocitrate cause inhibition of aconitase. In brain tissue, both substances are preferentially taken up by glial cells and leads to inhibition of the glial TCA cycle. It is important to realise, however, that the glia-specificity of these compounds depends bo
