Secondary Metabolites Antioxidant Activities and Yield of Celery Affected by Different Harvesting Maturity

Abstract

This research investigated the effects of four stages of harvest maturity (30, 45, 60 and 75 days after planting) on secondary metabolites, antioxidant activities and yield of Celery. The experiment was arranged in a randomized complete block design (RCBD). The results showed yield of celery was highest with harvest maturity at 75 days. In addition, the flavonoid content, vitamin C, phenolic compound content and antioxidation activity in terms of DPPH and ABTS radical scavenging capacity were highest (3.81 mg QE/g DW, 7.83 mg/100 g, 18.90 mg GAE/g DW, 53.82% and 48.57%, respectively) when the plants were harvested at 30 days after planting.
