Introduction
Glucosinolates (GLSs) are a group of β-thioglucoside
N-hydroxysulphates with a sulphur-linked β-d-glucopyranose
moiety and side-chain group. GLSs are secondary metabolites
derived mainly from one of certain amino acids, such
as methionine, tryptophan, and phenylalanine. Depending on
side-chain group, glucosinolate (GLS) can be classified either
as aliphatic, aromatic, or indolyl [1–3].
