An approach to the study of the fungal deterioration of a classical art material: Mastic varnish 69
Romero-Noguera,Julio; López-Miras,María del Mar; Martín-Sánchez,Inés; Ramos-López,José Miguel; Bolívar-Galiano,Fernando.
Mastic, one of the best natural varnishes, is frequently used as protective and finishing layer or as component of oleo-resinous media in paintings, both in the past and currently. However, this resin is affected by complex deterioration processes which can change its characteristics and thus the visual aspect of works of art. The alteration processes caused by radiation have been widely studied, but there is a lack of information on the biodeterioration of this natural product. In this paper, fungi from collections as well as from oil paintings of the Fine Arts Museum of Granada (Spain) were inoculated onto slides covered with mastic. The samples, after an incubation period of 15 days, were analysed by gas chromatography-mass spectrometry (GC-MS) to...

ABSTRACT: Essential oils are the most important compounds produced during secondary metabolism in aromatic plants. Essential oils are volatile, have characteristic odor and are used as defensive agents by plants. In pepper, it is possible to say that essential oils are the “flavor fingerprint” of each species. In the present article, eight species of pepper were studied in order to extract their essential oils and oleoresins, test their antibacterial and antifungal activities and also to identify the compounds present in the most bioactive samples. Results demonstrated that two essential oils [Pimenta dioica (L.) Merr. and Schinus terebinthifolius] and three oleoresins (Schinus terebinthifolius and Piper nigrum white and black) recorded significant...

Biodeterioration patterns found in dammar resin used as art material 69
Romero-Noguera,Julio; Martín-Sánchez,Inés; López-Miras,María del Mar; Ramos-López,José Miguel; Bolívar-Galiano,Fernando.
Since the middle of the XIX century, when dammar became popular in Occident, this natural resin is one of the most used in art painting techniques as final protective coating (varnish) as well as a component of pictorial media. The present work is the first approach to the study of the microbiological biodeterioration of this artistic material, which can seriously affect the appearance and integrity of works of art when bad conservation conditions -especially high humidity levels- take place. 12 microorganisms, fungi and bacteria, came from collection and from oil paintings affected by biodeterioration patterns, were inoculated on test specimens prepared with varnish dammar. These were incubated and analyzed by GC-MS to determine both the microbiological...

KARIM,M.; JABEEN,K.; IQBAL,S.; JAVAID,A..
ABSTRACT Mango (Mangifera indica) is one of the most important trees grown mainly in the tropical and subtropical countries. Anthracnose disease caused by Colletotrichum gloeosporioides, is the most damaging disease causing reduction of flower set and yield losses in mango. The present study was designed to evaluate antifungal activity of Datura metel extracts against C. gloeosporioides. Extracts (1% to 3%) of different parts of D. metel viz. leaves, seeds and roots were assessed for their antifungal potential. Methanolic seed extract of D. metel depicted the highest antifungal potential against the test fungus. All the applied concentrations effectively reduced growth of the test fungus. However, 1.5% conc. of methanolic seeds extract showed maximum...

Brazilian roasted coffee oil obtained by mechanical expelling: compositional analysis by GC-MS 116
Oliveira,Alessandra L. de; Cruz,Paulo Marcio; Eberlin,Marcos N.; Cabral,Fernando A..
A preliminary analysis by GC-MS comparing the mass spectrum of the compounds with the Wiley 275 L mass spectral data base was used to identify the fatty acids and mainly, some volatile compounds responsible for the flavor of the roasted coffee oil. The oil was obtained by mechanical expelling of Brazilian beans (Coffea arabica) roasted at 238ºC for 10 minutes. Different sample preparation methodologies such as headspace, adsorbent suction trapping and esterification were used. It was possible to identify pyrazines, pyridines, furan derivatives and other compounds not reported in the literature.

SUN,Haiyan; CHEN,Weiwei; JIANG,Yun; HE,Qiao; LI,Xiaolin; GUO,Qigao; XIANG,Suqiong; XI,Wanpeng; LIANG,Guolu.
Abstract Aroma differences are generally sensed in white- and red-fleshed loquats. Here, volatile compounds in four white- and three red-fleshed loquat varieties were investigated by headspace solid-phase microextraction and combined analysis of electronic nose (e-nose) and gas chromatography-mass spectrometry (GC-MS). In total, 83 volatile compounds were identified, and 33 were common in all of the cultivars. D-limonene, hexanal, (E)-2-hexenal, octanal and nonanal were the most abundant volatile compounds. β-cyclocitral and β-ionone were only detected in red-fleshed varieties. Furthermore, Huayu Seedless 1 (triploid white-fleshed loquats) with low levels of terpenoid compounds detected by GC-MS were clearly differentiated from the other cultivars tested...

n-alkanes from Paepalanthus Mart. species (Eriocaulaceae) 39
Santos,Lourdes Campaner dos; Dokkedal,Anne L.; Sannomiya,Miriam; Soares,Maria Carla Piza; Vilegas,Wagner.
This work presents the study of nonpolar compounds from plants belonging to the genus Paepalanthus Mart. (Eriocaulaceae). Long-chain linear aliphatic hydrocarbons were identified by GC-FID and GC-MS. The results indicate that Paepalanthus subg. Platycaulon species present a very homogenous profile, with carbon chains of n-alkanes ranging from C25 to C31, most samples presenting higher frequencies of C27 and C29 homologues. Paepalanthus subg. Paepalocephalus species may be distinguished from one another by the distribution of main n-alkanes. P. macrocephalus, subsect. Aphorocaulon species, presents alkanes with odd-carbon numbers and P. denudatus and P. polyanthus, Actinocephalus species, present alkanes with quite distinctive profiles, with many shorter...

Oligosaccharides in the honeydew of Coccoidea scale insects: Coccus hesperidum L. and a new Stigmacoccus sp. in Brazil 44
Bogo,Amauri; Mantle,Peter.
Analysis of the honeydew from an as yet undescribed, though distinctive, Brazilian Stigmacoccus sp. (near S. asper Hempel) by paper chromatography, Fast atom bombardment (FAB-MS) and Gas chromatography-mass spectrometry (GC-MS) identified fructose and glucose as monosaccharides and sucrose, maltose, trehalulose, trehalose and a hexose-hexitol as disaccharides. Erlose and glucosyl erlose have been identified as the tri- and tetra-saccharides in Stigmacoccus sp. and characterised for the first time in scale insects by modern techniques of linkage analysis. The same erlose oligosaccharides were recognised in honeydew of the common scale insect Coccus hesperidum L., together with the pentamer of this series, maltosyl erlose, therefore recognising that specific...

Two fast screening methods (GC-MS and TLC-ChEI assay) for rapid evaluation of potential anticholinesterasic indole alkaloids in complex mixtures 42
Vieira,Ivo J.C.; Medeiros,Walter L.B.; Monnerat,Cecilia S.; Souza,Jucimar J.; Mathias,Leda; Braz-Filho,Raimundo; Pinto,Angelo C.; Sousa,Priscila M.; Rezende,Claudia M.; Epifanio,Rosângela De A..
The pharmacotherapyfor Alzheimer's disease (AD) includes the use of acetylcholinesterase inhibitors (AChEI). Recent investigations for novel AD therapeutic agents from plants suggested that Tabernaemontana genus is a promising source of novel anticholinesterasic indole alkaloids. In this work two fast screening techniques were combined in order to easily identify novel cholinesterase inhibitors (ChEI). Gas chromatography-mass spectrometry (GC-MS) of the less polar alkaloidic fractions obtained from the acid-base extraction of the stalk of T. laeta revealed thirteen monoindole alkaloids, four of them confirmed by co-injection with previously isolated alkaloids. The others were tentatively identified by mass fragmentation analysis. By gas chromatography with...

Menezes,Joyce Castro de; Borges,Gabriela Borba Vilela; Gomes,Fátima de Cássia Oliveira; Vieira,Mariana de Lourdes Almeida; Marques,Andréa Rodrigues; Machado,Ana Maria de Resende.
ABSTRACT: The interest in the use of green tea (Camellia sinensis) (L.) Kuntze (Theaceae) products have increased in the last few years due to its medicinal properties. In the present study, we proposed that headspace solid phase microextraction, in combination with gas chromatography coupled to mass spectrometric could be an efficient method to assess the volatile compounds and to ensure the quality control of C. sinensis. We have also compared the anatomical leaf of different commercial green tea samples, analyzed the information in their labels and determined the presence of foreign materials, moisture content, total ashes and microorganisms. Among the 30 analyzed samples, six were identified as C. sinensis according to the anatomical study; 83.4% were...
