The purpose of the present research work is to investigate the functional group and category of secondary metabolites present in the essential oil (Eo) from Pogostemon benghalensis using Fourier transform infrared (FTIR) spectrometry, HPTLC and GC-MS technique. FTIR measures the vibrations of bonds within the functional groups and yields a spectrum that can be considered as biochemical or metabolic fingerprint of the plant product. Using FTIR spectra, it is possible to find out the minor changes of primary and secondary metabolic characteristic functional groups which are responsible for their biological feature of the species. FTIR is a nondestructive, cost effective, user and eco-friendly tool. Pogostemon benghalensis, a wild relative of P. cablin, the highly utilized and adulterated medicinal herb by the native people for the extraction of essential oil Patchouli. The fresh leaves were subjected to hydro distillation for the extraction of the essential oils and were analyzed using the above techniques. The FTIR spectral lines have shown diverse unique peaks of functional groups. FTIR confirmed the volatile compounds and indicated by their functional groups of the essential oils such as C-H (Alkene), C-H (aromatic) and C=C. Similarly, the analysis proved the presence of alcohols, p-substituted alcohols or phenols, alkanes, alkynes, alkenes, aldehyde, ester, ether, aliphatic amines, carboxylic acids, aromatics, ketones, disulphide, alkyl halides, halogen, and nitro derivatives. The intensity and estimation of predominant volatiles were analysed by HPTLC, which showed 8 peaks with max Rf values ranged from 0.07 to 0.96. Further, the Eo was fractionated by with GC-MS technique and identified 41 volatile fractions in the oil. Thus, the obtained data provides the biochemical profiles with overlapping signals of a wide array of molecules that are present in the cells. So, the usage of essential oils in pharmacy, cosmetology and aromatherapy industries may be substantiated. Further advanced spectroscopic analysis is required to identify the structure and nature of active principles present in the Eo.

“…Being 1,8-cineole the most abundant compound in both EOs, it should be expected that the main vibrational bands in the spectra arise from it. In fact, the bands at 1053 and 1079 cm -1 can be found in the spectrum of cineole ( (Boughendjioua & Boughendjioua, 2017) which correspond to the C-O stretching vibrations of the molecule. Other vibrational bands associated with 1,8-cineole were the symmetrical bending of the methyl CH bonds and -C-O-stretching vibration at 1375 cm −1 (Michelina, Naviglio, Gallo, & Severina, 2019), the C-O-C asymmetric and symmetric stretching at 1217 and 1080 cm −1 , respectively, and the CH2 wagging at 988 cm −1 corresponding to ring deformation vibrations (González-Rivera et al, 2016).…”

The aim of this work was to develop novel active edible electrospun coatings with antimicrobial properties through the encapsulation of essential oils (EOs) from two widely used spices (Laurus nobilis and Rosmarinus officinalis) for inactivating or reducing spoilage and pathogenic microorganisms. Firstly, EOs from dried leaves of both plants were obtained by hydrodistillation and their composition was analysed by Gas Chromatography-Mass Spectrometry (GC-MS). Interestingly, the main component in both extracts, probably as a consequence of the extraction conditions, was 1,8 cineole. Both EOs showed highest antimicrobial activity against Gram-positive than Gram-negative bacteria. Three different concentrations of the 1,8 cineole-rich EOs were incorporated within a zein matrix through electrospinning and solution properties, encapsulation yield, morphological and thermal stability of the edible coatings developed were evaluated. Then, the antibacterial efficiency of EOszein nanofibers (ZNF) films against Listeria monocytogenes, S. aureus and mesophilic bacteria counts (MBC) was compared with their counterparts prepared by casting (ZF) when applied directly on an inoculated side of cheese slices. EO obtained from Laurus nobilis showed higher antibacterial activity than Rosmarinus officinalis. The antibacterial effectiveness of the active films increased through storage time, showing a significant reduction of  2 logarithm units of L. monocytogenes and S. aureus as compared with the control samples, after 28 days at 4 ºC, using the highest content of 1,8 cineole-rich EOs and in films prepared by means of the electrospinning process. Interestingly, the growth of aerobic mesophilic bacteria was also inhibited in cheese slices coated with EOs-loaded ZNF based films.

“…In this way, the authenticity of materials could be determined by using the unique FTIR spectral data. Lemon essential oil is composed of terpenes (about 94% mainly (+)- limonene), sesquiterpenes, and aldehydes [ 22 ]. Identical spectral features were observed in the FTIR spectra of three cold-pressed lemon essentials, as can be seen in Figure 1 A.…”

Essential oils are high-valued natural extracts that are involved in industries such as food, cosmetics, and pharmaceutics. The lemon essential oil (LEO) has high economic importance in the food and beverage industry because of its health-beneficial characteristics and desired flavor properties. LEO, similar to other natural extracts, is prone to being adulterated through economic motivations. Adulteration causes unfair competition between vendors, disruptions in national economies, and crucial risks for consumers worldwide. There is a need for cost-effective, rapid, reliable, robust, and eco-friendly analytical techniques to detect adulterants in essential oils. The current research developed chemometric models for the quantification of three adulterants (orange essential oil, benzyl alcohol, and isopropyl myristate) in cold-pressed LEOs by using hierarchical cluster analysis (HCA), principal component regression (PCR), and partial least squares regression (PLSR) based on FTIR spectra. The cold-pressed LEO was successfully distinguished from adulterants by robust HCA. PLSR and PCR showed high accuracy with high R2 values (0.99–1) and low standard error of cross-validation (SECV) values (0.58 and 5.21) for cross-validation results of the raw, first derivative, and second derivative FTIR spectra. The findings showed that FTIR spectroscopy combined with multivariate analyses has a considerable capability to detect and quantify adulterants in lemon essential oil.
