“…Coriander oil could also reduce blood glucose and HbA1c levels, enhance insulin release and protect pancreas against diabetic pathological changes [11]. GC-MS analyses of coriander oils revealed variations in their composition that could be attributed to the variation in their geographical sources and extraction methods; however, linalool was the major component in all of them [9,12,13].…”

In the present study, we aimed to investigate the effect of coriander oil on dexamethasone-induced insulin resistance in rats and characterize its chemical composition using gas chromatography-mass spectrometry (GC-MS). Rats were divided into five groups (n = 6): Normal control, insulin resistance (IR) control, IR + metformin (50 mg/kg/day, PO, Per Oral), IR + coriander oil low dose (0.5 mL/kg, PO), and IR + coriander oil high dose (1 mL/kg, PO). IR groups were injected with a dose of 10 mg/kg dexamethasone subcutaneously for four consecutive days. All groups received either vehicle or drugs daily for four days. Animal weights and pancreatic weights were measured, and oral glucose tolerance test was performed at the end of study. Fasting glucose, triglycerides (TG), total cholesterol (TC), HDL and insulin levels in serum, MDA, and GSH levels in pancreatic tissue were measured and HOMA-IR was calculated. Immunoexpression of apoptosis markers BAX, and BCL2 was measured in pancreatic tissues and BAX/BCL2 ratio was calculated. Histopathological examination of pancreatic tissues was also performed. Pancreatic weight, serum HDL, pancreatic GSH, and BCL2 were decreased while serum glucose, insulin, TG, TC levels, AUC of OGGT, HOMA-IR, pancreatic MDA, BAX, and BAX/BCL2 ratio were increased in IR rats. Histopathological examination showed congestion, vacuolation and hemorrhage in pancreatic islets. These changes were reversed by metformin and the high dose of coriander oil treatments. The obtained activities could be attributed to the presence of 21 volatile compounds, identified by GC-MS. Our study indicates that coriander oil can be used as an adjuvant antihyperglycemic agent in type 2 diabetes. Further experiments are needed to determine the therapeutic dose and the treatment time.

“…The control sample was beer without the addition of coriander seeds (beer with the addition of hops during boiling). The results presented by Jeleń et al [ 35 ] confirm the occurrence of linalool, geraniol, and camphor in coriander oil. In our research, typical aromatic hops for the production of wheat beers (Tettnanger 5.5% alpha acids) were also used as an addition.…”

In recent years, there has been a significant decline in interest in high-alcohol beers, while interest in low- and non-alcohol beers is growing. The aim of this study was to investigate the influence of the addition of coriander seeds at various stages of the production of low-alcohol wheat beer (mashing, boiling, and fermentation). The presented article uses biological methods to produce low-alcohol beer. For this purpose, first, the mashing process was modified (breaking 44 °C for 20 min, followed by 75 °C for 60 min). The chemical composition and aroma components of the obtained beers were determined using various chromatographic methods (HPLC, GC-MS, and GC-O). Differences were found between the aroma components depending on the stage of production at which the coriander seeds were added. Beers with the addition of coriander seeds at the fermentation stage had the highest terpene content (linalool, camphor, trans-linalool oxide, and γ-terpinene) and boiling (myrcene, limonene, citronellol, and geraniol). The least desirable process is the addition of coriander seeds at the mashing stage due to the lowest content of volatile compounds. Additionally, beers with the addition of coriander seeds for fermentation were characterized by a higher content of antioxidant compounds. This proves that the addition of coriander seeds during beer production could improve the fermentation process and modify the quality of the obtaining beer.

Due to their various applications, terpenes and terpenoids are secondary metabolites of industrial interest. These compounds can be found in a wide variety of organisms from virtually all biological kingdoms. However, it has been identified that various factors in the production process, such as the place and time of harvest, pretreatments, extraction, and purification, generate differences in the profile of terpenes and terpenoids that can be obtained from organisms. The first factor that influences the extraction of compounds is drying since an inappropriate choice of the drying method can lead to the loss of the compounds of interest or the appearance of others that arise due to the decomposition of the original molecules. Similarly, Soxhlet extraction is the most used method in the recovery of terpenoids due to its high extraction efficiency. However, unconventional extraction methods have proven to be effective alternatives for terpenoid recovery, particularly the use of microwave and high-pressure extraction, as well as the use of unconventional solvents, achieving extraction efficiencies equal to or greater than Soxhlet in shorter times. This review will address the differences observed in the extraction of terpenoids and the main factors that cause them, as well as a comparison of the advantages and disadvantages of the various methodologies for drying, extraction, and separation of these compounds.
