MORALES RICO, Carmen Luisa; MARRERO DELANGE, David; GONZALEZ CANAVACIOLO, Víctor Luis  e  SIERRA PEREZ, Roxana de la Caridad. Influence of the harvesting time on the composition of Salvia coccinea L. oil. Rev Cubana Plant Med [online]. 2015, vol.20, n.3. ISSN 1028-4796.

The seeds of S. coccinea growing in Cuba show a high content of ω-3 and ω-6 fatty acid. It has been described the influence of the harvesting time on the fatty acid seeds composition of Salvia genus; however, until now no studies of this type have been conducted for the species in our country. The aim of this study was to determine the influence of harvesting time on content and composition of seeds oil of S. coccinea growing in Cuba by gas chromatography. The harvesting time did not influence the yield of seeds oil extraction, but did significantly affect its fatty acid composition. Linolenic acid was the main fatty acid, in all harvesting times whose concentrations were significantly increased in the coldest months. On the other hand, palmitic acid was the minor fatty acid and reached its highest concentration in the warmest month. Both behaviors were correlated with the temperature variation; however, other factors such as rainfall and solar radiation were not taken into account in this first study.
