Abstract:The
effects of experimental repetitions and solvent extractors
on the 1H NMR fingerprinting of yerba mate extracts, obtained
from two genders and two light environments, were analyzed in-depth
by ANOVA–simultaneous component analysis (ASCA). Different
solvents were used according to a mixture design based on ethanol,
dichloromethane, and hexane and their combinations. The number of
experimental repetitions significantly affected the ASCA results.
Increasing repetitions led to decreases in the percentage effect… Show more
