2.5. Determination of relative abundance of the
phytochemicals
Following the identification of the different phytochemicals
present in both ethanolic and water leaves extracts of A.
muricata, the relative abundance of the phytochemicals in
each of the extracts was determined[27]. The results were
analyzed using the Chi-square goodness of fit test between
low and high abundance. For each of the nine runs per
phytochemical, we allocated it as either high or low upon
which the final allocation of the relative abundance would
be based. Ho: The concentration of the phytochemical in the
sample is neither high nor low, thus No preference (average);
H1: There is a difference in the concentration of the
phytochemical in the sample; α=0.1, Expected value (E)=4.5,
Degrees of freedom=1 and χ2
critical=2.7055. All conditions of
the Chi-square test were met, except the standard minimum
expected value of 5, for which our expected value was 4.5, as
the total data set for each test was 9 values
