A260/A230 absorbance ratios
indicative of polyphenol and polysaccharide contamination were the
highest (ranging between 2.13 and 0.86) following extraction with the
proposed protocol, suggesting lower levels of contamination compared
with the other assessed protocols. As expected, fruit tissues displayed
lower purity levels due to high concentrations of polysaccharides and
phenolic compounds and low concentrations of RNA molecules,
resulting in low recovery or difficulty in quantifying the sample
