Effects of indoor, greenhouse, and field cultivation on bioactive compounds from parsley and basil

Aromatic herbs are an important source of bioactive compounds. Different cultivation systems should give each plant a specific amount of those compounds, which should be of a particular quality. In this study, the effects of three cultivation systems (indoor, greenhouse, and organic field) on the composition of bioactive compounds in parsley (Petroselinum crispum cv. 'Flat Leaf'), green basil (Ocimum basilicum var. minimum cv. 'Greek'), and purple basil (Ocimum basilicum cv. 'Red Rubin') were evaluated.

β-Carotene and lutein were the carotenoids with the highest concentration in the three plants in all the cultivation systems. Overall, parsley proved to be a source of flavonoids. The major phenolic compound found in basil plants was rosmarinic acid, whereas most anthocyanins were derived from cyanidin aglycone. Among the three plants studied, the highest vitamin C content was found in parsley from the field. This was 2.6 and 5.4 times higher than the indoor and greenhouse cultivation, respectively.

The results suggest that different cultivation systems influence and modulate the concentration of bioactive compounds in plants differently, varying according to their class, and that, above all, an indoor system is an effective cultivation system for the production of bioactive compounds. © 2021 Society of Chemical Industry.
