Determination of polyphenol levels variation in Capsicum annuum L. cv. Chelsea (yellow bell pepper) infected by anthracnose (Colletotrichum gloeosporioides) using liquid chromatography-tandem mass spectrometry

► Yellow bell pepper fruit were analysed for polyphenols by HPLC-MS/MS. ► The individual characterised components were quantified by HPLC-UV. ► Polyphenols as the defense materials against anthracnose have been discussed.
