Analysis of the Volatile Components of Pouteria sapota (Sapote Mamey) Fruit by HS-SPME-GC-MS

The comparison of SPME fiber coatings, and optimization of temperature and time of extraction for headspace solid phase microextraction (HS-SPME) of volatile organic compounds (VOCs) present in Pouteria sapota (sapote mamey) fruits is presented. The PDMS/DVB coating afforded the highest extraction efficiency. The extraction conditions were optimized by using Doehlert experimental design. By using the optimized HS-SPME method, 21 VOCs were identified, which include mainly terpenoids and esters, followed by aromatic hydrocarbons, aldehydes, alcohols and ketones. The most abundant compounds in Pouteria sapota pulp were cedrol (25.0%), azulene (7.3%), β-ionone (5.7%) naphthalene (5.6%), α-pinene (5.0%), and benzaldehyde (4.3%). Seventeen VOCs were identified for the first time in the fruit.

First Time

We report for the first time the chemical profiling of volatile organic compounds (VOCs) of gametophyte and sporophyte life stages of Leiosporoceros dussii, from Panama by using headspace-solid phase microextraction-gas chromatography-mass spectrometry in order to assess distinguishing chemical markers between the male and female gametophytes, and sporophytes of this hornwort. A total of 27 VOCs were identified in L. dussii. Furthermore, the gametophyte and sporophyte showed clear differences in the type and amount of VOCs. The main constituents of L. dussii female thalli were menthacamphor (17.8%), hexanol (12.3%), and menthyl acetate (12.3%), while the major compounds of the male thalli were hexanol (25.3%), β-ionone (21.1%), benzeneacetaldehyde (17.6%), and β-cyclocitral (14.0%). The main VOCs of the sporophytes were hexanal (19.3%), β-cyclocitral (17.6%), 2-nonenal (15.8%), hexanol (12.5%), and β-ionone (10.2%). Unique compounds found in the female thalli were 3-pentanone, 3-octenol, nonanol, estragole, and menthyl acetate, and in the male thalli were methyl heptenone, nonanal, neoisomenthol, and bornyl acetate. Isomenthol, thymol, isomenthol acetate, and β-methylnaphthalene were only found in the sporophyte. The characteristic VOCs identified in L. dussii suggest a difference between the chemical constituents of L. dussii and other hornworts species. The presence of simple VOCs when compared with compounds previously characterized in another hornwort genera may support the distinct genetic nature of this species.

Sample Amount

Volatile components fromExocarpium Citri Grandis(ECG) were, respectively, extracted by three methods, that is, steam distillation (SD), headspace solid-phase microextraction (HS-SPME), and solvent extraction (SE). A total of 81 compounds were identified by gas chromatography-mass spectrometry including 77 (SD), 56 (HS-SPME), and 48 (SE) compounds, respectively. Despite of the extraction method, terpenes (39.98~57.81%) were the main volatile components of ECG, mainly germacrene-D, limonene, 2,6,8,10,14-hexadecapentaene, 2,6,11,15-tetramethyl-, (E,E,E)-, andtrans-caryophyllene. Comparison was made among the three methods in terms of extraction profile and property. SD relatively gave an entire profile of volatile in ECG by long-time extraction; SE enabled the analysis of low volatility and high molecular weight compounds but lost some volatiles components; HS-SPME generated satisfactory extraction efficiency and gave similar results to those of SD at analytical level when consuming less sample amount, shorter extraction time, and simpler procedure. Although SD and SE were treated as traditionally preparative extractive techniques for volatiles in both small batches and large scale, HS-SPME coupled with GC/MS could be useful and appropriative for the rapid extraction and qualitative analysis of volatile components from medicinal plants at analytical level.

First Time

We report for the first time the chemical composition of volatile components (VOCs) of two subspecies, D. hirsuta subsp. hirsuta and D. hirsuta subsp. nepalensis, of the liverwort Dumortiera hirsuta from Panama by using headspace-solid phase microextraction-gas chromatography-mass spectrometry in order to assess distinguishing markers between the two species. Forty VOCs were identified in total for both subspecies. Of these, 34 are reported for the first time in D. hirsuta. Furthermore, both subspecies showed clear differences in the type and amount of VOCs. The major compounds in D. hirsuta subsp. hirsuta were α-gurjunene, β-selinene, α-guaiene, α-humulene and β-caryophyllene; while in D. hirsuta subsp. nepalensis were ledene, α-gurjunene, β-caryophyllene and α-guaiene, respectively. Two oxygenated sesquiterpenes, globulol and nerolidol, could be considered as possible distinguishing chemical markers between these two subspecies. We conclude that both morphotypes of D. hirsuta are chemically different.

Experimental Parameters

AbstractVolatiles are important flavor compounds of fruit juices and beverages. In this study, a headspace Solid-phase microextraction (SPME) gas chromatography-mass spectrometry (GC-MS) was used to analyze the volatile components in starfruit juices. Several experimental parameters (e.g. adsorption temperature, adsorption time, and sample volume) were optimized to improve sampling efficiency in two aspects; maximum adsorption and selective adsorption of volatile components onto SPME fiber. The following conditions were found to be optimal for selectivity and sensitivity: adsorption temperature of 50°C for 30 min, with a 65 μm divinylbenzene /polydimethylsiloxane (DVB/PDMS)-coated fiber with a sample volume of 15 g in a 30-ml vial. The proposed technique could be applied for the analysis of volatile compounds that contribute to starfruit juices flavor in different cultivars, and also their ripening stages.

Ideal Method

The artificial production of Ophiocordyceps sinensis mycelia and fruiting bodies and the Chinese cordyceps has been established. However, the volatile components from these O. sinensis products are not fully identified. An efficient, convenient, and widely used approach based on headspace solid-phase microextraction (HS-SPME) combined with comprehensive two-dimensional gas chromatography and quadrupole time-of-flight mass spectrometry (GC×GC-QTOFMS) was developed for the extraction and the analysis of volatile compounds from three categories of 16 products, including O. sinensis fungus, Thitarodes hosts of O. sinensis, and the Chinese cordyceps. A total of 120 volatile components including 36 alkanes, 25 terpenes, 17 aromatic hydrocarbons, 10 ketones, 5 olefines, 5 alcohols, 3 phenols, and 19 other compounds were identified. The contents of these components varied greatly among the products but alkanes, especially 2,5,6-trimethyldecane, 2,3-dimethylundecane and 2,2,4,4-tetramethyloctane, are the dominant compounds in general. Three categories of volatile compounds were confirmed by partial least squares-discriminant analysis (PLS-DA). This study provided an ideal method for characterizing and distinguishing different O. sinensis and insect hosts-based products.

First Time

Numerous volatile organic compounds (VOCs) with a large chemical diversity are emitted by plant flowers. They play an important role in the ecology of plants, such as pollination, defense, adaptation to their environment, and communication with other organisms. The Tillandsia genus belongs to the Bromeliaceae family, and most of them are epiphytes. The aromatic profile of the Tillandsia genus is scarcely described. In this study, we use the headspace solid phase microextraction (HS-SPME) coupled with gas chromatography combined with mass spectrometry (GC-MS) method developed in our laboratory to explore the chemical diversity of the VOCs of fragrant flowers of three species of the genus Tillandsia. We were able to identify, for the first time, 66 volatile compounds (monoterpenes, sesquiterpenes, phenylpropanoids, and other compounds). We identified 30 compounds in T. xiphioides, 47 compounds in T. crocata, and 43 compounds in T. caliginosa. Only seven compounds are present in all the species studied. Comparison of the volatile compounds profiles by principal component analysis (PCA) between T. xiphoides, T. crocata, and T. caliginosa species showed a clear difference in the floral emissions of the studied species. Moreover, floral VOCs profiles allowed to differentiate two forms of T. xiphioides and of T. crocata.
