The Myrtaceae family is of angiosperms, imposing its size and economic, cultural, and scientific importance. The genus Myrciaria, belonging to this family, has 33 species currently accepted, many of which are research targets aimed at elucidating their bioactive compounds and biological activities. Most species of the Myrciaria genus have terpenes in their composition, mainly mono and sesquiterpenes, and phenolic compounds such as tannins, phenolic acids, and flavonoids. Other secondary metabolites are also observed, such as alkaloids, steroids, coumarins, saponins, and naphthoquinones. These bioactive compounds are closely related to these species′ most diverse biological activities: antioxidant, anti‐inflammatory, analgesic, antiproliferative, antimicrobial, antiparasitic, insecticide, metabolic, protective, and nutraceutical. This work aims to provide a review of secondary metabolites and medicinal properties related to the genus Myrciaria, thus stimulating further studies on the species of this genus.

Eugenia pyriformis, typically known as uvaia, ubaia, uvaieira, uvalha or uvalha‐do‐campo, is a plant representative of the Myrtaceae family. E. pyriformis decreased HeLa cells proliferation, can induce cell death and reduce cell migration that may be related to metastasis and induction of cell death by apoptosis in vitro assays. Its leaves are used in folk medicine for hypertension control, decreased cholesterol and uric acid, slimming, astringent, and digestive. In this work, the evaluation of the in vitro anticancer potential Cervical Cancer (HeLa cells) and phytochemical analysis in E. pyriformes was performed. It was possible to quantify phenolic compounds and total flavonoids and identify Chlorogenic acid, Quercetrin, and Myricitrin in this species. The crude extract and ethyl acetate fraction inhibited cell viability by 50 % in the dose of 44.42 μg/mL and 40.39 μg/mL, respectively. The induced effector caspase 3/7 activation, which results in apoptosis and the ethyl acetate fraction, decreases cell migration of cancer cell lines; it is responsible for the cleavage of several cellular proteins that will result in the classic phenotype of the apoptotic cell.
