dc.description.abstract |
Quinoa is an Andean grain known for its gluten-free grains, which are used as a functional
food. The aim of this research was to study the possibility of introducing quinoa as a vegetable crop
grown for young leaves as a source of polyphenols and phytosterols. To achieve this goal, a field
experiment was performed with three quinoa cultivars (Titicaca, Puno, and Vikinga) grown in a
split plot design. The experimental factors included three densities (160, 320, and 760 plants m2)
and two harvest dates (52 and 62 days after sowing (DAS)). The content of phytosterols (ergosterol,
stigmasterol, -sitosterol and campesterol) and polyphenols (ferulic acid, isoquercitrin and
rutozid) in quinoa leaves were determined by HPLC method. The phytosterol content varied within
the limits: ergosterol 0–7.62 g 100 g1 dw, stigmasterol 79.9–175.3 g 100 g1 dw, -sitosterol
425.7–623.1 g 100 g1 dw and campesterol 0–5.25 g 100 g1 dw. Ferulic acid varied greatly from
38.0 to 63.3 g g1 dw, isoquercitrin ranged from 63 to 101.6 g g1 dw and rutozid varied widely
from 32.9 to 162.8 g g1 dw. The total phytosterols and the total phenolic compounds decreased
with decreasing plant number density and DAS. This research demonstrated that young quinoa
leaves are a good source of phytosterols and phenolics for human consumption. |
