Mean values were compared (𝑛=3) by nonparametric Kruskal wallis one way ANOVA. Differences in alphabets are significantly different atP < 0.05. Percent gain or loss calculated when raw value taken as 100%. Percent recovery values are given in parentheses. Decimal points are not given due to higher numbers.
