1-Methylcyclopropene is used as an agrochemical in the form of supramolecular complexes with various receptors to extend the shelf life of fruits and vegetables. In the present work we studied and compared three different preparations: supramolecular complexes of 1-methylcyclopropene with cucurbit[6]uril and α-cyclodextrin, as well as a newly developed multicomponent preparation based on supramolecular complex of 1-methylcyclopropene with α-cyclodextrin. To control the content of 1-methylcyclopropene in vegetable storage air, a gas chromatography method was adapted from the literature for determination of 1-methylcyclopropene in gas-air mixtures. A comprehensive procedure has been developed that includes sampling of gas-air mixtures, their transportation, and gas chromatographic analysis, ensuring reliable quantitative determination of 1-methylcyclopropene in the air of vegetable storages. Laboratory tests and experiments under real conditions of use were carried out, and the concentrations of 1-methylcyclopropene at the maximum level were shown to be quite close for these three preparations, which indicates the comparable efficiency thereof.
