Abstract

Litchi fruit is consumed across the globe for its high nutritional value and taste. The qualitative profil- ing of litchi fruit has been carried out by using ultra-high- performance liquid chromatography with QExactive high- resolution accurate mass spectrometry. Acidified water: methanol: acetonitrile (1:1:1) extracts from individual parts (skin, pulp, and seed) of matured litchi, were subjected to LC–MS analysis with electrospray ionization in full MS- ddMS 2 mode as a non-target approach. The data was pro- cessed through compound discoverer software by the use of mzCloud and ChemSpider databases, for compound iden- tification. We identified 77 compounds with protonated or deprotonated forms based on the polarity and their charac- teristic fragments are within ± 4 ppm mass error and reten- tion time ± 0.1 min for parent and fragments. Hypoglycin B is the first time reported in litchi fruit along with hypoglycin A. Further, we verified the distribution of the identified com- ponents and differentiation of three different parts of litchi through principal component analysis.
