Composição química do hidrolato de Cymbopogon winterianus (Jowitt ex Bor) E Lavandula dentata L. cultivadas no município de Realeza, Sudoeste Paranaense

Abstract

Medicinal herbs such as Cymbopogon winterianus (citronella) and Lavandula dentata (lavender) have a very ancient history in medicine, as they are often used to improve human health, due to their potential therapeutic benefits. The objective of this study is to add knowledge about the use of medicinal plants, thus highlighting their high therapeutic potential in the areas of human health, which can be an alternative source of antimicrobial, repellent and antifungal medicines. With the study, we intend to evaluate the chemical composition of citronella and lavender hydrolates cultivated in the autumn of 2023, in the city of Realeza, Southwest Paraná, Brazil. The extraction of hydrolates took place in the Organic Chemistry Laboratory of the Federal University of Fronteira Sul, Campus Realeza-PR. The chromatographic analyzes were sent to the Analytical Center of the University of Santa Cruz do Sul-SC. The results obtained revealed that citronella and lavender hydrolates are chemically similar to essential oils, but with some variations, obtaining smaller quantities for some chemical components and larger quantities for others. The main chemical constituents of the citronella plant are Geraniol, Cis-p-menthane 3,8-diol, Terpinem-4ol. The chemical components of Camphor, Eucalyptol and Fenchona were found in lavender.
