Purpose: To carry out gas chromatography-mass spectrometry (GC-MS) analysis of the phytochemical content of the root essential oil of Saussurea lappa Clarke Asteraceae (Costus, SLEO), and to evaluate its physicochemical, antimicrobial and cytoxic properties. Methods: The oil was extracted from the plant’s roots by steam distillation using a Clevenger system. Various physicochemical parameters for the oil including refractive index, color, acid value, saponification number, ester and peroxide values were measured. Flavonoid content was assessed using thin layer chromatography (TLC). Thermoscientific trace ultra gas chromatograph equipped with a Thermoscientific capillary TR-5MS column was utilized to determine the volatile components of SLEO. Antimicrobial activity of SLEO was performed against various Gram (+ve) and Gram (-ve) microorganisms, viz, Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Candida albicans, while cytotoxic effect was monitored using Artemia salina (brine shrimp) lethality assay. Results: Essential oil yield was good (3 %). Concentration-dependent antimicrobial effects were observed on all test microorganisms and no marked difference in lethality levels was observed among the tested SLEO concentrations on brine shrimp (p < 0.05). The main component of SLEO was costunolide or eudesma-5,11(13)-dien-8,12-olide (52.01 %). Conclusion: The results indicate the promising therapeutic properties of S. lappa. However, further phytochemical and biological investigations are required to establish the mechanism of action and toxicological the extract.

The present study investigated the chemical composition and bioactivities of the leaf essential oil from R. anthopogon from Dhankuta, Nepal. The essential oil from leaves was obtained by hydrodistillation and a detailed chemical analysis was conducted by gas chromatography – mass spectrometry (GC-MS). The enantiomeric distribution of monoterpenoid components was determined using chiral gas chromatography and represents the first chiral examination of R. anthopogon essential oil. The essential oil was screened for antimicrobial activity using the microbroth dilution test, and for cytotoxic activity against MCF-7, MDA-MB-231, and 5637 using the MTT assay. A total of 70 volatile components were identified from the essential oil. The major components were α-pinene (21.5%), δ-cadinene (13.8%), β-pinene (9.5%), limonene (5.9%), δ-amorphene (4.6%), α-muurolene (4.5%), and ( E)-caryophyllene (3.2%) with other minor constituents (< 3%).

Background: Different endemic species of Apiaceae that widely grow in Hyrcanian region have long been used as spices and herbal remedies. Chemical compositions and bioactivity of many of these plants have not been studied scientifically. The volatile constituents and antimicrobial activity of four edible Apiaceae plants—Elaeosticta glaucescens Boiss, Malabaila secacul (Mill.) Boiss, Caucalis platycarpos L., and Eryngium caucasicum Trautv—roots were investigated. Methods: Gas chromatography/mass spectrometry (GC–MS) and gas chromatography/flame ionization detection (GC–FID) methods were used for chemical investigation. Antimicrobial potential of the volatile compositions of these roots were investigated using the disc diffusion method on four microorganisms including Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and Bacillus subtilis. Results: The best minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of these species were revealed for B. subtilis and S. aureus (500 µg/mL for MIC and MBC) followed by E. caucasicum and C. platycarpus, respectively. The main compounds of E. caucasicum root essential oil were hexyl isovalerate (11.0%) and hexyl valerate (10.1%). E. glaucescens root essential oil was mainly composed of 3(10)-caren-4-ol, acetoacetic acid ester (9.8%), octyl isovalerate (8.9%), and octyl acetate (5.7%). In C. platycarpos root, hexyl isovalerate (9.2%) and n-octyl isobutyrate (8.5%) were constituted the major compositions of the essential oil while n-hexyl isobutyrate (8.5%) and hexyl hexanoate (7.8%) were predominant compounds in M. secacul. Conclusion: The essential oils of E. caucasicum and C. platycarpus roots were contained high amount of short chain fatty acid esters (SCFAE) and trans- pinocarvyl acetate. They exhibited moderate antibacterial activity.

Abstract Foeniculum vulgare Mill. is a medicinal plant, used as a flavouring agent. The essential oil from F. vulgare has potential antimicrobial and insecticidal effects, and can be used in food industry in order to protect the food resources and food products against microbial and pest’s contamination. The aim of the research was to characterize the volatile components of F. vulgare essential oil by Gas Chromatography/Mass Spectrometry (GC/MS) and Gas Chromatography (GC-FID) and to observe the antimicrobial activity by disk diffusion method and in vapour phase. Also, insecticidal activity of the vapour phase of the essential oil of F. vulgare was detected. We found that major components of the essential oil from F. vulgare were trans-anethole (73.6%), fenchone (6.0%), and limonene (5.7%). Antimicrobial activity on gram-positive, gram-negative, and yeasts was weak in liquid phase, but vapour phase showed stronger activity against B. subtilis at the concentration 250 μL.L−1 (98.65% of bacterial growth inhibition). Vapour phase of essential oil was effective against insects, where 25% concentration had 80% lethality.

Starting Point

Many natural products could serve as the starting point in the development of modern medicines because of their numerous biological and pharmacological activities. However, some of them are known to carry toxicological properties as well. In order to achieve a safe treatment with plant products, numerous research studies have recently been focused on both pharmacology and toxicity of medicinal plants. Moreover, these studies employed efforts for alternative biological assays. Brine Shrimp Lethality Assay is the most convenient system for monitoring biological activities of various plant species. This method is very useful for preliminary assessment of toxicity of the plant extracts. Rapidness, simplicity and low requirements are several advantages of this assay. However, several conditions need to be completed, especially in the means of standardized experimental conditions (temperature, pH of the medium, salinity, aeration and light). The toxicity of herbal extracts using this assay has been determined in a concentration range of 10, 100 and 1000 µg/ml of the examined herbal extract. Most toxicity studies which use the Brine Shrimp Lethality Assay determine the toxicity after 24 hours of exposure to the tested sample. The median lethal concentration (LC50) of the test samples is obtained by a plot of percentage of the dead shrimps against the logarithm of the sample concentration. LC50 values are estimated using a probit regression analysis and compared with either Meyer’s or Clarkson’s toxicity criteria. Furthermore, the positive correlation between Meyer’s toxicity scale for Artemia salina and Gosselin, Smith and Hodge’s toxicity scale for higher animal models confirmed that the Brine Shrimp Lethality Assay is an excellent predictive tool for the toxic potential of plant extracts in humans.

The volatile components of essential oils of fresh aerial parts from horseweed (Conyza canadensis) collected in October with hydrodistillation and steam distillation, respectively, were analyzed by gas chromatography-mass spectrometry. The results showed that limonene, β-pinene, trans-α-bergamotene, cis-β-ocimene, β-myrcene, germacrene D, 1,3,8-p-menthatriene, caryophyllene, (E)-β-farnesene, (Z)-β-farnesene, α-curcumene, caryophyllene oxide were the common volatile components in the essential oils between hydrodistillation and steam distillation. High limonene content (68.87%) was in the essential oil with hydrodistillation. Limonene or other terpenoids has the potential to develop as the biomimetic synthesis template for environmentally-friendly herbicide.
