Determination of Phenolic Compounds and Chlorophyll Content of Spinach (Spinacia oleracea L.) at Different Growth Stages

Abstract

The aim of this studies is to determine variations in total phenolic compound and chlorophyll contents in spinach (Spinacia oleracea var. matador), which was grown in unheated glasshouse growth chamber facilities, occurred in three different growth stages like cotyledon, 5 true leaves and harvest maturity. According to the findings, greenhouse ambient yielded the highest mean in early spring spinach production with respect to different growth environment according to the criteria under consideration (119.88 mg/100 g) and was followed by open field and growth chamber. According to comparison of growth stages of spinach grown in three different growth environments, amounts of total phenolic compound (121.25 mg/100 g), total chlorophyll (877.93 mg/L), chlorophyll a (13.89 mg/L) and chlorophyll b (1.12 mg/L) increased towards the harvest phase in which the most maturated and aged plant was achieved. In other words, these matters were, accumulated depending on the plant's growth.
