“…This HS-SPME-GC-MS procedure is an effective and rapid analytical method for direct profiling of the volatile (30) can be identified in the headspace above T. minuta samples by use of this technique. The profiles of the volatiles can, eventually, be used for classification of plants for medicinal, agricultural, or marketing proposes.…”

“…The results of our research show that T. minuta is particularly rich in as (E)-ocimenone (10.3%), cis-b-ocimene (4.8%), a-terpinolene (8.4%), trans-caryophyllene (19.7%), D-germacrene (10.0%), camphor (3.6%), bicyclogermacrene (6.2%), and piperitenone (12.3%). A literature survey [30,46] reveals that no Tagetes species has been found in which verbenone is a major constituent, so its identification is of potential importance to the genus. However, the percentage of minor constituents varies.…”

“…SPME has attracted increasing attention in environmental and food analysis because of its simplicity, efficiency, high precision, low detection limit, and ease of automation [24][25][26]. It has been used in many applications, including analysis of volatile and semi-volatile sulfur compounds in beer and Cheddar cheese [27], polycyclic musks in sewage sludge [28], nicotine in cigarette smoke [29], food taints [30], aldehydes in exhaled breath of patients with lung cancer [31], and codeine and morphine in human hair [32], for rapid discrimination of vegetable oil [33], and for analysis of water pollutants [34], aliphatic primary amines in wastewater [35], and volatile compounds in rice samples [36].…”

Ultrasound-assisted headspace solid-phase microextraction (UA-HS-SPME) coupled to gas chromatography-mass spectrometry (GC-MS) has been used for analysis of volatile compounds in dry Tagetes minuta L. The highest extraction efficiency was achieved with a 100-lm polydimethylsiloxane (PDMS) fiber. Different experimental conditions, for example, type of fiber coating, sonication time, extraction time and temperature, and desorption time, were investigated. Thirty compounds were identified by use of this UA-HS-SPME-GC-MS method. Comparison of the method with the commonly used hydrodistillation (HD) method showed that the proposed method is simpler, needs much less sample, requires shorter extraction time and lower temperature, has high trapping ability, and extracts more volatile and thermally sensitive compounds. The major components identified by use of the method were E-ocimenone (10.3%), cis-b-ocimene (4.8%), a-terpinolene (8.4%), trans-caryophyllene (19.7%), germacrene-D (10.0%), and camphor (3.6%).

“…Stir bar sorptive extraction (SBSE) introduced in 1999 has been widely applied in trace analysis in environmental, food, and biomedical fields for its extremely high sensitivity , due to the large amount of extraction phase. SBSE is based on the same principle as SPME, but the extraction phase is usually hundreds of times larger than that of SPME.…”

Stir bar sorptive extraction is an environmentally friendly microextraction technique based on a stir bar with various sorbents. A commercial stirrer is a good support, but it has not been used in stir bar sorptive extraction due to difficult modification. A stirrer was modified with carbon nanoparticles by a simple carbon deposition process in flame and characterized by scanning electron microscopy and energy-dispersive X-ray spectrometry. A three-dimensional porous coating was formed with carbon nanoparticles. In combination with high-performance liquid chromatography, the stir bar was evaluated using five polycyclic aromatic hydrocarbons as model analytes. Conditions including extraction time and temperature, ionic strength, and desorption solvent were investigated by a factor-by-factor optimization method. The established method exhibited good linearity (0.01-10 μg/L) and low limits of quantification (0.01 μg/L). It was applied to detect model analytes in environmental water samples. No analyte was detected in river water, and five analytes were quantified in rain water. The recoveries of five analytes in two samples with spiked at 2 μg/L were in the range of 92.2-106% and 93.4-108%, respectively. The results indicated that the carbon nanoparticle-coated stirrer was an efficient stir bar for extraction analysis of some polycyclic aromatic hydrocarbons.

A water compatible molecularly imprinted polymers (MIPs) coated stir bar for bisphenol A(BPA) was prepared with 3,3',5,5'-tetrabromobisphenol A as the dummy template molecule in this study. The dummy molecularly imprinted polymers coated stir bar (DMIPs-SB) showed better selectivity than the bars coated with polydimethylsiloxane or non-imprinted polymers when used to extract BPA and its three analogues. The saturated adsorption amount of the DMIPs coating was 3.0 times over that of the non-imprinted polymers coating. To achieve the optimum extraction performance, several parameters, including extraction and desorption time, pH value, adsorption temperature and stirring speed were investigated. The high-performance liquid chromatography combined with the DMIPs-SB was employed in the analysis of BPA in aqueous solution. The linear range of BPA concentration in aqueous medium was 0.0228-2.28 ng/mL with correlation coefficient of 0.9994 and the detection limit was about 6.84 × 10(-3) ng/mL based on three times ratio of signal to noise. This method was directly applied to the determination of trace BPA in milk with satisfactory results.
