Lemongrass Essential Oil

: Essential oils are complex mixtures of volatile compounds, primarily composed of terpenes and abundant aromatic plants. For example, Cymbopogon citratus (lemongrass) is an aromatic plant that produces a monoterpene-rich essential oil, and studies show that this essential oil has excellent antioxidant activity. Erythrocytes incubated under high sugar levels are constantly exposed to reactive oxygen species, which results in the oxidation of their membranes. Objective: The aim of this article is to investigate the antioxidant activity of lemongrass essential oil and its protective effect on erythrocytes exposed to high levels of glucose. Materials and Methods: The essential oil was obtained by steam dragging distillation; blood cell suspensions were incubated with glucose 5, 20, 50, and 100 mmol/L. The amount of TBARS produced was measured at 532 nm. In addition, the percentage of antioxidant activity was assessed by DPPH free radical assay. Results: Lemongrass essential oil showed an increase in the antioxidant activity up to 240 mg/ml, while ascorbic acid used as positive control showed a dose-dependent increase in antioxidant activity starting at 1 mmol/L up to 18 mmol/L. However, such a lemongrass dose prevented peroxidation in erythrocytes incubated under a high glucose media, whereas ascorbic acid showed a protective effect only at a concentration of 1 mmol/L. Conclusion: Lemongrass essential oil has high antioxidant activity compared to standard antioxidant as ascorbic acid, and also acts as a protective agent against erythrocyte lipoperoxidation due to hyperglycemia in vitro.

The objective of this research was to evaluate in vitro the inhibitory activity of essential oils from fresh leaves of Cymbopogon citratus (lemongrass) against Colletotrichum gloeosporioides in yam. The research was conducted in the department of Sucre, Colombia. The essential oils of C. citratus were collected in the municipalities of Sincelejo, La Union and Sampues, in September and October 2015. The essential oil was extract from fresh leaves using the microwave-assisted hydrodistillation. Concentrations of 5000, 8000 and 10 000 ppm of each essential oil were prepared. An absolute control, a positive control (benomyl 1 g/l) and a negative control was used. An inhibitory activity was obtained by using the direct seeding on surface of the potato-dextrose-agar method and it was expressed as percentage of inhibition rate. The chemical characterization of essential oils was performed by gas chromatography coupled to mass spectrometry. The highest percentages of antifungal index were observed in the lemongrass from Sincelejo at concentrations of 5000, 8000 and 10 000 ppm, after in La Union at 8000 and 10 000 ppm, and finally at Sampues at 10 000 ppm, with a value of 97.77%; the effect was similar to the positive control with benomyl 1 g/l. Citral was the main constituent of the essential oils extracted. The essential oils obtained from the three municipalities showed antifungal activity against C. gloeosporioides.

Candidiasis is an important nosocomial infection with high morbidity value, high mortality rate, and expensive clinical cost. However, public access to well-developed treatment is not acquired. Current medicines mostly used like -azol drugs had been showing the resistant effects because of the long period use of the same medicines. Alternative medicines like herb medicine are discussed to reduce multi-resist infections, such as lemongrass Cymbopogon citratus essential oil. This study aims to know the effect of lemongrass essential oil on the growth of Candida albicans in vitro. Laboratory experimental (in vitro) was conducted in this research. Candida albicans strains were being used as the objects, which were picked by random sampling. Candida albicans were divided into 12 groups of treatment, the group I was treated with ethanol 96% as the negative control, group II with fluconazole 25μg as the positive control, and group III-XII with Cymbopogon citratus essential oil with 10%, 20% to 100% concentrated. The diameter of inhibition zones was measured after 2x24 hours incubation. The data was analyzed by post-hoc Mann Whitney test with SPSS 18.0 (p<0.05 considered as significant). Cymbopogon citratus essential oil showed antifungal activity to the Candida albicans began in the 10% to 100% concentration (p<0.05). Inhibition zones with the 50% to 100% concentration had similar results to the positive control (p>0.05). The Cymbopogon citratus essential oil has an antifungi effect toward Candida albicans in vitro significantly by the negative control.

Coriandrum sativum L. is an aromatic plant belonging to the Apiaceae (Umbelliferae) family, originating in the Mediterranean region. C. sativum is widely cultivated worldwide and has nutritional and medicinal values. The C. sativum seeds contain an essential oil that is used in different industries like pharmaceuticals, cosmetics, and food. This study aims to extract, analyze, and evaluate the antioxidant activity of C. sativum seed essential oil cultivated in Afghanistan. The essential oil was extracted by hydro-distillation (HD) extraction and analyzed by High-performance thin-layer chromatography (HPTLC). The HD extraction provided an essential oil yield of 0.16 % (v/w). Also, HPTLC analysis of the essential oil determined two components of the oil, linalool and myrcene. The quantification of linalool content and HPTLC method validation were determined using densitometric analysis. As a result, the linalool content was identified 60.06 %, and the HPTLC method proved as a valid method for analysis of the essential oil. Furthermore, the antioxidant activity of the essential oil was determined using DPPH radical scavenging assay and reported as IC50. The ascorbic acid utilized as the positive control, and the antioxidant activity of the essential oil evaluated in comparison with ascorbic acid. The IC50 of ascorbic acid and the essential oil were determined 0.02 ± 0.0004 (mg/ml) and 21.05± 0.284 (mg/ml), respectively. Thus, the essential oil showed lower antioxidant activity than ascorbic acid. This study is the first report on the extraction, chemical composition, and antioxidant activity of C. sativum seed essential oil cultivated in Afghanistan.

Lemongrass Essential Oil

Background: The essential oil of methyl eugenol rich Cymbopogon khasianus Hack. was evaluated and its bioactivities were compared with pure methyl eugenol. So far, methyl eugenol rich essential oil of lemongrass was not studied for any biological activities; hence, the present study was conducted. Objective: This study examined the chemical composition of essential oil of methyl eugenol rich Cymbopogon khasianus Hack., and evaluated its antioxidant, anti-inflammatory, antimicrobial, and herbicidal properties and genotoxicity, which were compared with pure compound, methyl eugenol. Material and Methods: Methyl eugenol rich variety of Cymbopogon khasianus Hack., with registration no. INGR18037 (c.v. Jor Lab L-9) was collected from experimental farm CSIR-NEIST, Jorhat, Assam (26.7378°N, 94.1570°E). The essential oil wasobtained by hydro-distillation using a Clevenger apparatus. The chemical composition of the essential oil was evaluated using GC/MS analysis and its antioxidant (DPPH assay, reducing power assay), anti-inflammatory (Egg albumin denaturation assay), and antimicrobial (Disc diffusion assay, MIC) properties, seed germination effect and genotoxicity (Allium cepa assay) were studied and compared with pure Methyl Eugenol compound (ME). Results: Major components detected in the Essential Oil (EO) through Gas chromatography/mass spectroscopy analysis were methyl eugenol (73.17%) and β-myrcene (8.58%). A total of 35components were detected with a total identified area percentage of 98.34%. DPPH assay revealed considerable antioxidant activity of methyl eugenol rich lemongrass essential oil (IC50= 2.263 μg/mL), which is lower than standard ascorbic acid (IC50 2.58 μg/mL), and higher than standard Methyl Eugenol (ME) (IC50 2.253 μg/mL). Methyl eugenol rich lemongrass EO showed IC50 38.00 μg/mL, ME 36.44 μg/mL, and sodium diclofenac 22.76 μg/mL, in in-vitro anti-inflammatory test. Moderate antimicrobial activity towards the 8 tested microbes was shown by methyl eugenol rich lemongrass essential oil whose effectiveness against the microbes was less as compared to pure ME standard. Seed germination assay further revealed the herbicidal properties of methyl eugenol rich essential oil. Moreover, Allium cepa assay revealed moderate genotoxicity of the essential oil. Conclusion: This paper compared the antioxidant, anti-inflammatory, antimicrobial, genotoxicity and herbicidal activities of methyl eugenol rich lemongrass with pure methyl eugenol. This methyl eugenol rich lemongrass variety can be used as an alternative of methyl eugenol pure compound. Hence, the essential oil of this variety has the potential of developing cost-effective, easily available antioxidative/ antimicrobial drugs but its use should be under the safety range of methyl eugenol and needs further clinical trials.

Objective: Ziziphora clinopodioides is an edible medicinal plant belongs to the Labiatae family that widespread all over Iran. It used as culinary and also in cold and cough treatments in Iran. The aim of present work was to evaluate the effect of different timeframes during the hydrodistillation on essential oil composition, antimicrobial and antioxidant activity. Materials and Methods: The essential oil of Z. clinopodiodes was extracted via hydrodistillation with Clevenger apparatus. The fractions of essential oil were captured at 6 times from the beginning of the distillation: (10, 20, 60, 120, 180 and 240 min). The fractions of essential oil were analyzed by GC/MS and their antibacterial, antifungal and antioxidant activities were studied by Disk - well diffusion and DPPH methods respectively. Results: Six distillation times and whole essential oil were captured during the hydrodistillation. Essential oil yield dropped off significantly during distillation progressed (1.0% for 10 min and 0.025 for 240 min). 1,8 Cineol, Isomenthone, Pulegone, Piperitenone and Citronellic acid were major compounds in fractions and they were affected by distillation times. Pulegone was major compound in all of essential oils. In antioxidant activity assay, whole essential oil was stronger than was stronger than positive control and fractions of essential oil, because of higher levels of Isomenthone, Piperitenone and Citronellic acid. Strongest antimicrobial activity against S. aureus, E. coli and C. albicans was observed from 10 min fraction. Conclusion: Our results indicated that distillation time can create essential oils with specific properties and we can achieve to more efficient essential oil in short times.

The investigation aimed to study the in vitro and in silico antioxidant properties of Melissa officinalis subsp. officinalis essential oil (MOEO). The chemical composition of MOEO was determined using GC–MS analysis. Among 36 compounds identified in MOEO, the main were beta-cubebene (27.66%), beta-caryophyllene (27.41%), alpha-cadinene (4.72%), caryophyllene oxide (4.09%), and alpha-cadinol (4.07%), respectively. In vitro antioxidant properties of MOEO have been studied in 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) free-radical scavenging, and inhibition of β-carotene bleaching assays. The half-maximal inhibitory concentration (IC50) for the radical scavenging abilities of ABTS and DPPH were 1.225 ± 0.011 μg/mL and 14.015 ± 0.027 μg/mL, respectively, demonstrating good antioxidant activity. Moreover, MOEO exhibited a strong inhibitory effect (94.031 ± 0.082%) in the β-carotene bleaching assay by neutralizing hydroperoxides, responsible for the oxidation of highly unsaturated β-carotene. Furthermore, molecular docking showed that the MOEO components could exert an in vitro antioxidant activity through xanthine oxidoreductase inhibition. The most active structures are minor MOEO components (approximately 6%), among which the highest affinity for the target protein belongs to carvacrol.
