The spectrophotometric quantification of LP was performed by the quantification of MDA levels, using samples of plant material homogenized in 0.1% (w/v) trichloroacetic acid (TCA) [49]. After reading the absorbance (Abs) at 532 and 600 nm (unspecific turbidity) and considering an extinction coefficient of 155 mM cm−1, MDA levels were calculated and the results expressed in nmol g−1 fw.
