Results indicated that the extracted purple carrots contained
about 168.70 mg/100 g on fresh weight of anthocyanins pigments;
the results declared that purple carrots contained high
concentration of total anthocyanins. These results are in agreement
with that obtained by Mazza and Miniati (1993).
Identification of anthocyanins for purple carrots by HPLC
Anthocyanins pigments extracted from purple carrots were
separated and identified by HPLC are shown in Table 3 and
Fig. 1.
Spectral measurements and HPLC separation indicated the
presence of five anthocyanins for purple carrots. Results in
Fig. 1 and Table 3 indicated the detected types of anthocyanin
pigments for purple carrots namely Cyanidin-3-xylosylglucosyl-
galactoside (peak 1), Cyanidin-3-xylosyl-galactoside
(peak 2), Cyanidin-3-xylosyl-glucosyl-galactoside acylated with
sinapic acid (peak 3), Cyanidin-3-xylosyl-glucosyl-galactoside
acylated with coumaric acid (peak 4) and Cyanidin-3-xylosylglucosyl-
galactoside acylated with ferulic acid (peak 5),
respectively.
