The purpose of this work was the isolation, identification and quantitative determination of the water-soluble organic constituents present in the flesh of dried prune (Prunus domestica). This work was prompted by the recent appearance of two Russian papers (12) (32) identifying some of the organic constituents of prunes. Quinic acid was first isolated and identified as a constituents of prunes in 1931. Although the method used for the isolation was not quantitate, it was indicated that prunes contained about 1% quinic acid on the fresh basis (15). According to a paper appearing in 1935, whole dried prunes contain no chirogenic acid but contain about 0.03% caffeic acid (23). Caffeic acid is a component part of chiorogenic acid, 3-0-caffeouiquinic acid. It was concluded from rabbit studies that the caffeic acid present in prunes is not responsible for the aperient action caused by the ingestion of purnes. (see more in text)
