Microwave-assisted hydrodistillation extraction of essential oil from coriander seeds and evaluation of their composition, antioxidant and antimicrobial activity

Abstract

Coriander seeds essential oil is used in food preparation, perfume, cosmetics and pharmaceuticals. In this study, extraction of essential oil from coriander seeds was done by hydrodistillation (HD) and microwave assisted hydrodistillation (MAHD) methods. Chemical composition, total phenol contents, antimicrobial and antioxidant properties of essential oils were measured and the results were compared between HD and MAHD methods. Scanning electron microscopy (SEM) results showed that the essential oils had inhibitory effect on the bacterial membrane and cell wall. Results showed that total phenol contents and antioxidant activity increased under heat and microwave conditions. Coriander seeds essential oil had a very strong effect on Candida albicans . Gram-positive bacteria were more sensitive to the essential oil of coriander seeds than Gram-negative bacteria. The essential oil extracted by MAHD showed better antimicrobial activity, higher phenols yield and antioxidant activity. According to the results of GC-MS, linalool was the most common constituent of both essential oils.

Determination of Volatile Terpenes in Coriander Cold Pressed Oil by Vacuum Assisted Sorbent Extraction (VASE)

“…Subcritical water extraction compared to hydrodistillation and Soxhlet extraction revealed similar percentages of linalool (82.91%, 77.97%, and 79.62%, respectively,) but for geranyl acetate, varied greatly (0.22%, 2.12%, and 4.36%, respectively) [ 18 ]. Microwave assisted hydrodistillation may offer a significant reduction of extraction compared to classic hydrodistillation (60 min vs. 240 min) providing similar profiles of compounds in extracted essential oil [ 3 ]. When Schmaus and Kubecka [ 19 ] compared lavender oil profiles obtained using hydrodistillation (at pH 7.0) with that of extraction and gas phase stripping, the percentage composition of extracted linalool changed from 40.91% in hydrodistillation to 24.95% and 25.78% for extraction and stripping, respectively.…”

“…Nowadays, coriander is a common herb around the world [ 1 ]. Coriander has a number of therapeutic properties (e.g., antibacterial, anticancer, antidiabetic, antimutagenic, antioxidant, anti-inflammatory, analgesic, anticonvulsant, blood pressure-lowering, cholesterol-lowering, and sedative activities [ 2 , 3 ]) desired in the medical and pharmaceutical industries, due to the presence of specific metabolites. Coriander has been used in traditional medicine for ages to counteract several disorders, such as dysentery, dyspepsia, giddiness spasm, neuralgia, and gastric complaints [ 4 ].…”

The analysis of flavonoids and triterpenes extracted from Urtica by LC‐MS and the antimicrobial activity of the extracts

“…The culture dish with the lowest drug concentration was found from the sterile growing dish by observing the growth of bacteria. The minimum drug concentration was the MIC (Ghazanfari et al, 2020;Moghimi et al, 2016), and the culture was continued (48-72 hr for the fungus, 24 hr for the bacteria). The minimum drug concentration was MBC in the sterile growing dish (Moghimi et al, 2016).…”

Chemical Composition, Antioxidant, and Anti-Inflammatory Activity of Essential Oil from Omija (Schisandra chinensis (Turcz.) Baill.) Produced by Supercritical Fluid Extraction Using CO2

“…[ 23 ], and Zingiberaceae [ 24 ], have been reported. Furthermore, essential oils not only show functional activity, but also have the advantage of reducing various side effects reported by using synthetic compounds [ 25 ]. These essential oils have been obtained from aromatic plants in various ways, such as water steam distillation, clevenger hydrodistillation, cold press extraction, and solvent extraction [ 26 ].…”
