RODRIGUEZ CEPEDA, Rodrigo  and  ALVAREZ SUAREZ, Nelsy Yanet. Antimicrobial activity of thehydroalcoholic extract of Calendula officinalis L. Rev. ion [online]. 2021, vol.34, n.1, pp.97-110.  Epub Jan 01, 2021. ISSN 0120-100X.  https://doi.org/10.18273/revion.v34n1-2021008.

The current search for natural products, with some functions as food additives, are of great research interest due to their industrial projection. For this reason, this document shows the results of an exploratory study on the antibacterial activity of a hydroalcoholic extract of Calendula officinalis L., which was characterized by phytochemical analysis, Infrared Attenuated Total Reflection (IR-ATR) spectroscopy, and gas chromatography coupled to masses (CG-MS). The antimicrobial power was determined on Pseudomona aeruginosa, Staphyloccocus aureus, and Candida albicans. Finally, an application was made on strawberry (Fragaria chiloensis L.) to observe the effect on the useful life of the fruit, this in environmental conditions of temperature 20 ° C and relative humidity 70%. The results show that the hydroalcoholic extract is a mixture of various chemical compounds, with properties as active biocomposites. Finally, the presence of tannins, carotenoids, and phenolic compounds, among others, which, according to the study of antimicrobial activity, improved the useful life of F. chiloensis L is evidenced.
