• a Retention times (for peak apex) are consistent with those shown in Fig. 1<\$REFLINK> .

• b Approximate percentage values with respect to the weight of the fractions obtained by integration of HPLC peak areas after baseline correction and comparison with authentic standards. Values are the mean of duplicate determinations from one experiment representative of two.
