ABSTRACT
Anthocyanins have been associated with beneficial effects on human health. Cancer has been one of the main public health issues due to its aggressiveness and high mortality rate. This systematic review aimed to address recent research (from January 2000 to September 2021) on the anticancer activity of anthocyanins assessed by in vitro assays. The selected studies revealed that anthocyanins have anticancer potential by inhibiting cancer cell viability and proliferation, controlling cell cycle, and promoting apoptosis.

This study investigates the seasonal variation of three species of Leptospermum (Myrtaceae) grown in Brazil. The chemical composition of the volatile oils of L. flavescens and L. petersonii did not show any significant seasonal variation in the major components, while for Leptospermum madidum subsp. sativum the levels of major constituents of the volatile oils varied with the harvest season. Major fluctuations in the composition of L. madidum subsp. sativum oil included α-pinene (0-15.2%), ß-pinene (0.3-18.5%), α-humulene (0.8-30%), 1,8-cineole (0.4-7.1%) and E-caryophyllene (0.4-11.9%). Levels of ß-pinene (0.3-5.6%), terpinen-4-ol (4.7-7.2%) and nerolidol (55.1-67.6%) fluctuated seasonally in the L. flavescens oil. In L. petersonii, changes were noted for geranial (29.8-32.8%), citronellal (26.5-33.9%) and neral (22.7-23.5%). The activity of the volatile oils against the tested bacteria differed, depending on season the oils were obtained. In general, the volatile oils were more active against Gram-positive bacteria.
