RESUMEN
Native fruit trees have potential for use in the food and pharmaceutical industries, which is widely used in folk medicine. Guabiju, known as guabijuzeiro (Myrcianthes pungens (O. Berg) D. Legrand) is a perennial tree that belongs to the family Myrtaceae, occurring in Brazil from São Paulo to Rio Grande do Sul, and other countries like Uruguay, Bolivia, Paraguay and Argentina. This species demonstrates great commercial potential regarding the consumption of its fresh fruit or industrialized. Due to its importance is necessary to develop studies aimed at characterization (phenotypic, propagative, reproductive, chemical and nutritional), uses and applications. However, the available information has never been systematized and in this sense the objective of this review is to compile information about the species to guide further research. Regarding morphology, the guabijuzeiro is a semi-deciduous tree species, with propagation is carried out mainly through seeds and vegetative. Regarding reproductive aspects, there is a lack of studies that assess the mode of reproduction. The fruit can be consumed fresh or processed as ice cream, juice, freeze-dried or dehydrated. It is sweet and slightly acidic, low in calories, high in carbohydrates, essential fatty acids, calcium and potassium. Both the fruit, the seed and the leaves have high levels of bioactive compounds and high antioxidant capacity. The fruit pulp stands out for its carotenoids and phenolic compounds and the peel is rich in anthocyanins, especially in the mature phase, in addition to terpenoids. M. pungens has antimicrobial effects, gastroprotective activity and is promising in the prevention of neurodegenerative diseases and against the side effects of cisplatin, an anticancer agent. Finally, there is a need for further studies with this species, mainly in the characterization of the leaves, uses and applications of the fruit.
RESUMEN
BACKGROUND: 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. RESULTS: ß-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. CONCLUSION: 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.
