Identification of two terpenoids that accumulate in Chinese water chestnut in response to fresh-cut processing.

ABSTRACT: As a form of vegetable in China, freshly cut corms of Chinese water chestnuts (Eleocharis dulcis) are well received by consumers. Few studies have investigated the metabolites present in fresh-cut E. dulcis, particularly during the storage stage. Two compounds, triterpenoids and apocarotenoids, were identified in fresh-cut E. dulcis during the late storage period using thin-layer chromatography (TLC), high-performance liquid chromatography (HPLC), and nuclear magnetic resonance (NMR) spectroscopy. The content of these two compounds gradually increased in the surface tissue of fresh-cut E. dulcis during storage. Moreover, the transcript levels of 10 genes involved in terpenoid backbone biosynthesis and five genes involved in carotenoid precursor biosynthesis were
