“…Hexanal has oil and green apple aroma, naturally exists in many fruits and vegetables, which possesses volatile substances that contribute the most to the aroma of the fruits and vegetables (Janes et al, 2009). Benzaldehyde exists extensively in fruits and flowers (Krist et al, 2004;Radulovic et al, 2009), mainly in the form of glycosides in plants' stems, leaves or seeds, which has bitter almond flavor (Chu and Yaylayan, 2008).…”

“…Based on the transcriptome screening, cloning and functional characterization of one prenyltransferase (SaFDS) and four sesquiterpene synthases, including sesquisabinene synthases (SaSQS1 and SaSQS2), bisabolene synthase (SaBS) and santalene synthase (SaSS) has been carried out. Although, sesquisabinene and its hydroxy derivative, sesquisabinene hydrate have been reported to be present in various natural sources 26 27 , to the best of our knowledge, there is no report on the isolation and functional characterization of the gene which encodes sesquisabinene synthase. Furthermore, we have also evaluated the feasibility of microbial production of sesquisabinene from both the unigenes in non-optimized bacterial cells and demonstrated the feasibility of metabolic engineering of SaSQS1 and SaSQS2 for preparative scale production of sesquisabinene in metabolically tractable heterologous systems.…”

Indian Sandalwood, Santalum album L. is highly valued for its fragrant heartwood oil and is dominated by a blend of sesquiterpenes. Sesquiterpenes are formed through cyclization of farnesyl diphosphate (FPP), catalyzed by metal dependent terpene cyclases. This report describes the cloning and functional characterization of five genes, which encode two sesquisabinene synthases (SaSQS1, SaSQS2), bisabolene synthase (SaBS), santalene synthase (SaSS) and farnesyl diphosphate synthase (SaFDS) using the transcriptome sequencing of S. album. Using Illumina next generation sequencing, 33.32 million high quality raw reads were generated, which were assembled into 84,094 unigenes with an average length of 494.17 bp. Based on the transcriptome sequencing, five sesquiterpene synthases SaFDS, SaSQS1, SaSQS2, SaBS and SaSS involved in the biosynthesis of FPP, sesquisabinene, β-bisabolene and santalenes, respectively, were cloned and functionally characterized. Novel sesquiterpene synthases (SaSQS1 and SaSQS2) were characterized as isoforms of sesquisabinene synthase with varying kinetic parameters and expression levels. Furthermore, the feasibility of microbial production of sesquisabinene from both the unigenes, SaSQS1 and SaSQS2 in non-optimized bacterial cell for the preparative scale production of sesquisabinene has been demonstrated. These results may pave the way for in vivo production of sandalwood sesquiterpenes in genetically tractable heterologous systems.

Analyses by GC and GC/MS of an essential-oil sample obtained from dry fruits of Scandix balansae Reut. ex Boiss. allowed the identification of 81 components, comprising 91.4% of the total oil composition. Interestingly, the major identified volatile compounds were medium-chain-length n-alkanes, i.e., tridecane (6.7%), pentadecane (13.4%), and heptadecane (19.3%), and a long-chain homolog nonacosane (7.6%). A number of minor oil constituents, among them tetradecyl 3-methylbutanoate, and octadecyl 2-methylpropanoate, 3-methylbutanoate, and pentanoate, turned out to have a restricted natural occurrence not only in umbellifers but also in the Plant Kingdom, whereas the last ester is a new natural compound in general. The identity of these rare plant constituents that present excellent chemotaxonomic marker candidates for Scandix species was unambiguously confirmed by co-injection of the oil sample with appropriate standards, which were synthesized for this purpose and fully characterized ((1) H- and (13) C-NMR, IR, MS). To explore the possible applicability of the essential oils' compositional data in the taxonomy of Apiaceae, the herein studied and additional 58 oils obtained from Scandiceae taxa were compared using multivariate statistical analyses (MVA). MVA demonstrated that the evolution of the volatiles' metabolism of Scandiceae taxa was neither genera-specific nor follows their morphological evolution.
