Determination of the content of rutin and total polyphenols in leaves of spinach and amaranth

Popis výsledku v původním jazyce

In the years 2002 to 2004 the content of rutin and total polyphenols was determined in the leaves of spinach and amaranth using the HPLC method. The experiment included three amaranth species ? love-lies-bleeding (A. caudatus), red-blooded amaranth (A. cruentus) and red-spiked amaranth (A. hypochondriacus) and two spinach varieties ? Matador and Triptiek F1. It is evident from the results that average rutin content was lowest at the beginning of vegetation 159.11 mg.g-1 and the highest in the phase of elongation of stem ? 294.10 mg.g-1 (F = 2233.89, p=0.00). The highest average rutin content was recorded in A. hypochondriacus (234.54 mg.g-1) and on the contrary, the lowest one in A. cruentus ? 154.92 mg.g-1 (F=608.84, p=0.00). The difference in the content of total polyphenols in spinach leaves was statistically significantly influenced of development (F=165.84, p=0.00) when their lowest average content was at the beginning of spinach vegetation, i.e. 10.95 mg.g-1 and the highest in th
