Essential oil composition of “LAVANDULA STOECHAS” in Algeria (Jijel)

Abstract

The aim of this research is to calculate the yield of extracted oils of Lavandula stoechas L along with analyzing the chemical properties of these extracted oils using FTIR spectroscopy technology. The active ingredients were extracted from different parts of the plant (leaves, flowers, and aerial parts), and then the extraction yield and essential oil yield were measured to determine the amount of extract in different parts. The results showed that there is a variation in the yield according to the plant part, meaning that the number of materials obtained from the different parts varies in quantity. Infrared radiation (FTIR) was used to analyze the extracts in order to determine the chemical functional groups present in them. Through the obtained spectra, there are different signals related to different organic compounds such as O–H, C–H, and C=O bonds, which means the presence of organic compounds that lead to the chemical properties of the extracts. Through this study, it was shown that the extraction and production of essential oils differ according to the plant part, and the use of FTIR technology helped in determining the chemical composition of the extracts.
