Abstract

<abstract abstract-type="main"> <title>Abstract</title> <sec id="jsfa6142-sec-0001" sec-type="section"> <title>BACKGROUND</title> <p> <bold>Soybean sprouts (Kongnamool) are one of the most popular and nutritive traditional vegetables in East Asia. Anthracnose caused by <italic>Colletotrichum gloeosporioides</italic> is one of the most serious diseases of soybean sprouts. In order to obtain basic information for breeding and/or selecting soybean genotypes with increased natural defense against anthracnose, phenolic compounds were profiled for healthy and infected soybean (<italic>Glycine max</italic> Merr.) sprouts by using high‐performance liquid chromatography coupled with tandem mass spectrometry</bold>.</p> </sec> <sec id="jsfa6142-sec-0002" sec-type="section"> <title>RESULTS</title> <p> <bold>Tryptophan and eight phenolic compounds (daidzin, genistin, malonyldaidzin, malonylgenistin, daidzein, glycitein, genistein and coumestrol) were determined from healthy and inoculated sprouts. Total identified phenolic content was 40.02 ± 0.03 mg kg<sup>−1</sup>, 99.4% of which was isoflavones</bold>.</p> </sec> <sec id="jsfa6142-sec-0003" sec-type="section"> <title>CONCLUSION</title> <p> <bold>The monitoring suggested that <italic>de novo</italic> induced glycitein appeared to act as a phytoalexin in the defence mechanism of the soybean sprouts against <italic>C. gloeosporioides</italic>, and constitutively formed seven phenolic components that functioned as phytoanticipins in the diseased soybean sprouts</bold>. © 2013 Society of Chemical Industry</p> </sec> </abstract>
