Determination of volatile organic compounds in the dried leaves ofSalviaspecies by solid-phase microextraction coupled to gas chromatography mass spectrometry

Abstract

Salvia spp. are used throughout the world both for food and pharmaceutical purposes. In this study, a method involving headspace solid-phase microextraction combined with gas chromatography-mass spectrometry was developed, to establish the volatiles profile of dried leaves of four Iranian Salvia spp.: Salvia officinalis L., Salvia leriifolia Benth, Salvia macrosiphon Boiss. and two ecotypes of Salvia reuterana Boiss. A total of 95 volatiles were identified from the dried leaves of the five selected samples. Specifically, α-thujone was the main component of S. officinalis L. and S. macrosiphon Boiss. (34.40 and 17.84%, respectively) dried leaves, S. leriifolia Benth was dominated by β-pinene (27.03%), whereas α-terpinene was the major constituent of the two ecotypes of S. reuterana Boiss. (21.67 and 13.84%, respectively). These results suggested that the proposed method can be considered as a reliable technique for isolating volatiles from aromatic plants, and for plant differentiation based on the volatile metabolomic profile.

Aroma Profile of Two Populations of Salvia verbenaca Collected from Two Bio‐Geographical Zones from Jordan

“…mesatlantica MAIRE from Morocco contained mainly camphor (51.8 %) [20] which was completely absent from the emissions of the fresh Jordanian S. verbenaca organs from both zones. Cozzolino [21] Table 2 summarizes the variation in the composition of the volatiles obtained from fresh and dried aerial parts of different Salvia plants compared to our current findings. The great variation observed among the composition of the volatiles in the emissions of the different Salvia species and other plants could be attributed mainly to climatic and environmental factors.…”

“…(2016) investigated the composition of the scent extracted from the dried leaves of four Italian Salvia species including S. officinalis , S. leriifolia , S. macrosiphon , S. reuterana A and S. reuterana B. The scent of the dried leaves contained appreciable amounts of caryophyllene . Table summarizes the variation in the composition of the volatiles obtained from fresh and dried aerial parts of different Salvia plants compared to our current findings.…”

“…Identification of VOCs was based on comparing the obtained linear retention indices relative to n ‐alkane hydrocarbon (C 8 –C 20 ) series standard mixture and by computer matching against commercial libraries (NIST and Wile, USA). Moreover, the identity of several compounds including α ‐pinene, β ‐pinene, p ‐cymene, 1,8‐cineol, α ‐terpineol, limonene, ocimene, linalool, sabinene, allo ‐aromadendrene and caryophyllene (Sigma−Aldrich, Buchs, Switzerland) was further confirmed by the analyzing authentic standards under the same GC/MS conditions.…”

Bioactive Compounds and Aroma Profile of Some Lamiaceae Edible Flowers

“…No work was also found in both the studied species of Salvia genus, notwithstanding numerous published works on this subject [84][85][86][87][88][89][90][91][92][93][94]. The two studied species S. disc and S. micro, originating from South America, were grown under uniform conditions in CREA-Sanremo (Italy).…”

BiClusO: A Novel Biclustering Approach and Its Application to Species-VOC Relational Data

“…We collected species-VOC relationship data from the KNAp-SAcK metabolite ecology section of the KNApSAcK family databases [9]. We also collected additional data from different papers and journals using Google Scholar and other publication sites [24], [25], [26], [27], [28], [29], [30], [31], [32], [33], [34], [35], [36], [37], [38], [39], [40], [41], [42], [43], [44], [45], [46], [47], [48], [49], [50], [51], [52], [53], [54]. The final data consists of 12,410 species-VOC relations including 710 species and 1,740 different VOCs.…”
