“…The presence of flavones and dihydroflavones is determined by spectrophotometric methods by means of the reaction with 3.4-dinitrophenylhydrazine (DNP) andpinocembrin as a reference [ 12 , 14 , 15 ]; however, the use of chromatographic techniques should also be stressed [ 12 , 16 , 17 , 18 ]. On the other hand, the determination of the antioxidant capacity in propolis is measured by using the inhibiting activity of the ABTS (2.2-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) [ 19 , 20 , 21 , 22 ] and the linoleic acid/ β -carotene radical [ 19 , 23 , 24 , 25 , 26 , 27 ], withTrolox as a method of reference. These methods are specific to each compound and time-consuming; and they need important amounts of polluting solvents, while NIR technology is known for being a multiparametric, rapid, and non-destructive technique.…”
