Analysis of the volatile constituents ofApium graveolens L. andOenanthe L. by gas chromatography-mass spectrometry, using headspace solid-phase microextraction

Abstract

KeyWordsGas chromatography mass spectrometry Volatile constituents of celeryand water dropwort Headspaoe solid phase microextraction SummaryGas chromatography mass spectrometry with headspaoe solid phase microextraction was used for the analysis of the volatile constituents of celery and water dropwort. Solid phase mi croextraction was carried out wth a 65 u.m polydimethylsiloxane divinylbenzene fiber at 60 ~ for 45 rain. The fiber was desorbed in the GC iniection liner at 250 ~ for 3 rain. Thirty eTght compounds in calory and thTrty-five compounds Tn water dropwort were separated and idenCfied. The main compounds found in both calory and water dropwort included cis-3-hexen-l-ol, a~-myrcene, limonene, a-pinene, 1/i-cyclohexadiene, 1,5,5-trimethyl-6-methylene-cyclohexene, 3J,~l,15-tetramethyl-2-hexadecen-l-ol, n-hexadeconoic acid and a~-caryophyllena. The predsion of the method was studied by five replicate analysis of the main volatile compounds in celery and a relative standard deviation value less than 5.0% showed that the method could provide good reproducibili~

Gas chromatography-mass spectrometry with solid-phase microextraction method for determination of methyl salicylate and other volatile compounds in leaves of Lycopersicon esculentum

“…Recently, there were reports in several reviews of the application of SPME in environmental, biomedical and live biological analysis [12,13,14]. In our previous studies, SPME methods were developed for the analysis of volatile constituents of plant materials [15,16,17,18].…”

Separation and Identification of Volatile Constituents in Artemisia argyi Flowers by GC--MS with SPME and Steam Distillation

“…Gas chromatography-mass spectrometry (GC-MS) with steam distillation (SD) has been applied to isolation and identification of the essential oil (7), and 35 compounds in Artemisia argyi leaves were identified (7). In our previous work, a simple, rapid, and solvent-free method, GC-MS with headspace solid-phase microextraction (HS-SPME), was developed for the analysis of the essential oils in Artemisia argyi leaves and other TCMs (8)(9)(10)(11)(12)(13)(14)(15).…”

Chemical composition and antioxidant activity of the essential oil ofSchisandra chinensisfruits

“…The composition of the essential oil of S. chinensis obtained by steam distillation method and solid-phase microextraction has been published (Deng, Song, Hu, & Zhang, 2003;Li, Cui, Song, Liang, & Chau, 2003). According to Li et al (2003), -farnesene (14.37%), ylangene (11.93%) and patchulane (8.25%) constituted the major components of the essential oil.…”

“…According to Li et al (2003), -farnesene (14.37%), ylangene (11.93%) and patchulane (8.25%) constituted the major components of the essential oil. According to Deng et al (2003), the main compounds included -santalene (18.51%-22.14%), -cadinene (13.25%-20.42%), 2,4a,5,6,7,8-hexahydro-3,5,5,9-tetramethyl-1H-benzocycloheptene (13.31%-18.38%) and 4-isopropylidene-1-vinylmenth-8-ene (7.71%-9.42%). Literature is poor about studying comparatively the compositions of the essential oil from genus Schizandra species.…”
