Abstract

BackgroundThis study focused on the comparison of the essential oil percentage and constituents obtained from the dry seeds and the waste of coriander plant in order to reach the best ways to store the essential oil.ResultsThe chemical composition of coriander oil was analyzed by gas chromatography–mass spectrometry (GC–MS). The analysis of coriander essential oil showed that linalool was the main constituent of dry seed oil under all conditions. It recorded 59.6, 59.28 and 47.69% of the treatments of the oil at zero time, stored in cool conditions and stored at room temperature, respectively. Concerning oil constituents of coriander waste (the remained herb after collecting seeds), the results showed that trans-anethole was the major oil constituent, followed by linalool compound. The quality of the stored oil in the refrigerator after harvest was better than the stored oil from seeds or waste under room temperature.ConclusionThe changes have been observed in the chemical composition of coriander oil extracted from seed and waste subjected to different storage conditions. The waste of coriander can be considered a new source of essential oil.

Highlights

This study focused on the comparison of the essential oil percentage and constituents obtained from the dry seeds and the waste of coriander plant in order to reach the best ways to store the essential oil
Oil percentage In all cases, coriander wastes gave a high percentage of essential oil compared to those extracted from dry seeds
The constituents of coriander oil are greatly affected by the method of storage

Summary

Introduction

This study focused on the comparison of the essential oil percentage and constituents obtained from the dry seeds and the waste of coriander plant in order to reach the best ways to store the essential oil. Uses of essential oil ranging from personal beauty care, household cleaning products, to aromatherapy treatments and natural medicine (Ryman 1984; Reeds 2000; Salma et al 2018). Essential oil benefits come from their antimicrobial, antioxidant properties and anti-inflammatory. These therapeutic oils are growing rapidly in popularity because it works natural medicine and does not include any side effects. Coriander seeds are a good source of secondary plant metabolites such as polyphenols, especially phenolic acids and flavonoids (Zeković et al 2014). It has industrial applications in pharmaceutical applications
