Phytochemicals content in lettuce growing: system influence organic, conventional and hydroponic

Abstract

The presence of bioactive compounds in vegetables and fruits has contributed to a healthy and
quality diet. Lettuce (Lactuca sativa L.) is the vegetable of greater acceptance in the consumer
market, being source of vitamins, minerals and other compounds of the secondary metabolism
of plants. The objective of the present work was to evaluate the influence of the cultivation systems
(organic, conventional and hydroponic) on the content of bioactive compounds in lettuce.
The contents of phenolic compounds, anthocyanins and carotenoids were not influenced by
the different cultivation systems, however, the plants from the organic production system presented
lower flavonoid content. It was concluded that the production systems did not influence
the content of the bioactive compounds (phenolic compounds, anthocyanins, carotenoids),
except in the content of flavonoids.
