Effect of hydrogen peroxide treatment on the concentration of volatile compound in coriander seeds oil

Coriander seeds essential oil have shown some remarkable biological properties and health benefits. The coriander seeds used in Indonesia are imported and also treated with hydrogen peroxide before reaching consumers. Hydrogen peroxide is known to be a strong oxidizer, but so far, there has been no information that explains its effects on the essential oil composition and concentration in coriander seed. This study aims to determine the effect of using hydrogen peroxide and the drying method on the composition of essential oils in coriander seeds. Yield and volatile oil compounds were measured, and the results were compared between the hydrogen peroxide concentration (0,35 and 50% ) and drying method (mechanical drying (50 ℃) and room temperature drying). GC-MS analysis detected linalool as the most common volatile constituent in all treatments. The highest concentration of linalool compounds (70.16%) was found in seeds without hydrogen peroxide (0%) treatment combined with mechanical drying, followed by without hydrogen peroxide (0% H2O2) combined with room drying (23.74%), then by 35% hydrogen peroxide combined with room drying (18.71%), 35% hydrogen peroxidecombined with mechanical drying (18.84%), 50% hydrogen peroxide combined with room drying (22.18%) and by 50% hydrogen peroxide combined with mechanical drying (15.45%). Therefore, the yield was clearly affected only by hydrogen peroxide treatment where no hydrogen peroxide treatment gave the highest yield. The drying method did not have any significant effect on yield.

Aerial Parts

The essential oil from the aerial parts of Blumea perrottetiana was obtained by hydrodistillation and analyzed by GC-MS. The volatile oil is dominated by 2,5-dimethoxy- p-cymene (30.0%) and 1,8-cineole (11.0%) with lesser amounts of sabinene (8.1%), δ-cadinene (5.3%) and ( E)-caryophyllene (3.9%). The essential oil demonstrated notable insecticidal activity against the red flour beetle, Tribolium castaneum, consistent with traditional uses of the plant as an insecticide and anthelmintic.

The Difference

This study was conducted to determine the essential oil composition of some medicinal plants from herbalists that local community have interest in; The research was carried out in the Medicinal Plants Laboratory of Konya, in 2014 – 2015. The medicinal plants used in the research were supplied by herbalists and wholesalers who supply medicinal plants in Konya. At the end of this study, essential oil composition of medicinal plants ranged from 0.71 % (Daphne) to 5% (Thyme). The lavender essential oil composition ranged between 2% and 5%, while the composition of thyme essential oil ranged between 1% and 5%. There are several reasons for the change observed in the essential oil content of medicinal plants. In general, the effect of difference in the proportion of essential oils of the medicinal plants used in the study was as a result of the difference in regions, domestically and abroad where these plants were collected.

Larvicidal Activities

The essential oils of three species of Peperomia from the Amazon, Brazil, were hydrodistilled and their 96 volatile constituents identified by GC and GC-MS. The main constituents found in the oil of P. macrostachya were epi-α-bisabolol (15.9%), caryophyllene oxide (12.9%), myristicin (7.6%), an aromatic compound (6.6%) and limonene (5.4%). The oil of P. pellucida was dominated by dillapiole (55.3%), ( E)-caryophyllene (14.3%) and carotol (8.1%). The major volatile found in the oil of P. rotundifolia was decanal (43.3%), probably a fatty acid-derived compound, followed by dihydro-β-santalol (9.0%), ( E)-nerolidol (7.9%) and limonene (7.7%). The aromatic compounds elemicin, myristicin, apiole, dillapiole and safrole identified in these Peperomia species has been found also in Amazon Piper species. The oils and methanol extracts showed high brine shrimp larvicidal activities. The oil of P. rotundifolia (LC50 = 1.9 ± 0.1 μg/mL) was the more toxic, followed by the extract of P. pellucida (LC50 = 2.4 ± 0.5 μg/mL) and the oil of P. macrostachya (LC50 = 9.0 ± 0.4 μg/mL), therefore with important biological properties.
