Abstract
A study was made of changes in the quinic acid content in the organs of developing mung bean seedlings.As a preliminary experiment, the organic acid fraction was prepared from extracts of the seedlings, and subjected to paper chromatographic survey. A single spot corresponding to quinic acid was detected by spray with the periodate-thiobar-bituric acid reagent. A spot corresponding to shikimic acid was not detectable.The content of quinic acid was found to increase in the early stage of growth in both the light- and dark-germinated seedlings. The increase in the content was mostly observed in parts, plumule, epicotyl, hypocotyl and radicle of the seedlings. The content reached the peak at the 4th-5th days after sowing, and then it seemed to decrease both in the cotyledons and other parts.An experiment extended over a growing period of 16 days in the light indicated that the amount of quinic acid in the seedlings was maintained roughly constant over the experiment period, so that the concentration of the acid per fresh weight decreased depending on growth of the plants.
