“…The content of the main aroma-impact compounds from β-carotene degradation identified in the EOs [21,22] are presented in Table 2, and an example of the total ion current (TIC) chromatograms (GC-MS) of the analyzed EOs is given on Figure 2. Data in Table 2 are given as relative content (% of TIC) and as calculated true content (mg/100 g DW) in order to provide a better visualization of results, since the latter values are not influenced by co-distilled volatile species or compound characteristics [3]. In the calculations of constituents’ contents response factors were assumed equal for all compounds.…”

“…In general, this research has mainly targeted evaluation of tobacco quality or opportunities for improving or mimicking tobacco aroma. Considerably fewer reports focus on the obtaining of standard (traditional, established) natural aromatic products from tobacco intended for perfumery and cosmetics [3]. These aromatic products typically include tobacco concrete and tobacco absolute, used in fine perfumery (“tabac”, “dry” or “masculine” scented perfumes), and tobacco resinoid, used in the process of casing or top flavoring of tobacco blends for cigarettes and other tobacco products [4].…”

“…The objectives of this work were to provide an insight into the composition of Bulgarian tobacco EOs, on the basis of a comparison between the most important fragrance-shaping carotenoid degradation products in the EOs of the three major types of tobacco—Virginia (flue-cured), Burley (air-cured), and Oriental (sun-cured)—and in the respective traditional aroma products (concrete, resinoid, absolute), all obtained by established technologies and used in the fragrance producing industry. Since the fragrance of tobacco aroma products is directly related to the occurrence of certain classes of volatile compounds, among which are carotenoid-related derivatives, such concise information could have practical importance in the use of tobacco aroma products as natural ingredients in perfumery, cosmetics, and aromatherapy [3].…”

Tobacco (Nicotiana tabacum L.) aroma is an important attribute of tobacco quality and is influenced by a variety of minor chemical components, including carotenoid degradation products. The objectives of this work were to determine the content of the most important fragrance-shaping carotenoid degradation products in the essential oils (EOs) of the three types of Bulgarian tobacco—Oriental (OR), flue-cured Virginia (FCV), and Burley (BU)—and to compare them with other aromatic products from tobacco. The content of total carotenoids and β-carotene was highest in BU tobacco (22.23 and 20.34 mg/100 g DW, respectively), followed by OR (13.60 and 12.09 mg/100 g DW in variety “Plovdiv 7” (Pd7); 6.27 and 5.45 mg/100 g DW in “Krumovgrad” (Kr), and FCV (5.93 and 3.73 mg/100 g DW). EOs were obtained by hydrodistillation in an acidified medium, and the main aroma-impact compounds from carotenoid degradation (identified by GC-MS) were as follows: FCV-α-ionone (0.61 mg/100 g DW), dihydro-β-ionone (0.96 mg/100 g DW), β-damascenone (1.26 mg/100 g DW); BU-α-ionone (0.73 mg/100 g DW), dihydro-β-ionone (1.19 mg/100 g DW), β-damascenone (1.35 mg/100 g DW); OR(Kr)-α-ionone (0.20 mg/100 g DW), β-ionone (1.08 mg/100 g DW), dihydro-β-ionone (1.34 mg/100 g DW), β-damascenone (0.36 mg/100 g DW); OR(Pd7)-α-ionone (1.43 mg/100 g DW), dihydro-β-ionone (1.73 mg/100 g DW), β-damascenone (1.23 mg/100 g DW). Ionone and its derivatives were not identified in the aroma extraction products concrete, resinoid, or absolute. The results suggest that temperature, pH of the medium, process duration, and possibly other unknown factors affect carotenoid transformation. The study provides insight into the composition of tobacco EOs and may be of interest to the fragrance industry.

“…The biocatalysis of tobacco cembranoid diterpenes was first reported in 1987 [27]. As far as we know, cembranoid diterpenes are important aroma substances in tobacco [49]. To enhance the aroma of substances from fermented tobacco leaves, Bacillus megaterium NH5, obtained from the soil, was used to convert α-CBT-diol into two triols, and the addition of these two substances to cigarettes at a concentration of 0.0005% significantly enhanced the aroma of cigarettes and reduced the irritant effects of the smoke on the throat and lungs [50,51].…”

Cembranoids are carbocyclic diterpenes comprising four isoprene units and are natural products with a parent skeleton consisting of a 14-membered ring. They have gained wide interest in recent years and are a major hotspot in the research of natural product chemistry. Since 1962, various tobacco cembranoid diterpenes have been identified. This review systematically discusses and summarises the excellent antimicrobial, insecticidal, cytotoxic and neuroprotective activities of tobacco cembranoid diterpenes. These compounds show potential to be developed as botanical fungicides, cytotoxic drugs and drugs for the treatment of human immunodeficiency virus, Alzheimer’s disease, Parkinson’s disease, and other neurodegenerative diseases. However, there are relatively few studies on the structure–activity relationship (SAR) of tobacco cembranoid diterpenes. Therefore, future studies should focus on their structural modification, SAR and biogenic relationships.

“…The identification of the compounds was performed using commercial mass spectral libraries (NIST 14, Wiley 7th Mass Spectra Register) and retention times (linear retention indices, LRI) as previously described in Nedeltcheva-Antonova et al [ 68 ]. If the corresponding reference data were missing, the structures were suggested using their general fragmentation pattern and reference literature mass spectra.…”

Snakes rely heavily on chemical cues when foraging, searching for mates, etc. Snakes’ sex attractiveness pheromones comprise mainly heavy, semi-volatile compounds such as ketones. Here we investigated the composition of skin secretions of adult Vipera ammodytes (Linnaeus, 1758) individuals. The samples were analyzed by gas chromatography/mass spectrometry and the identification of the compounds was performed using commercial mass spectral libraries and retention times. The relative concentrations of all detected compounds were tested for significant differences between (1) male vs. female live individuals, (2) shed skin vs. live individuals, and (3) pre-reproductive vs. reproductive live individuals. We detected fifty-nine compounds of which six were ketones. Two ketones (2-pentacosanone and 2-heptacosanone) were present in many of the samples and thus may have an important role in the V. ammodytes chemical communication. We did not find significant differences between the relative concentrations of the compounds between male and female individuals (only three compounds are exceptions). Significant differences were found between extracts from shed skins and live individuals and between live pre-reproductive individuals and live reproductive individuals. The results of the study suggest that chemical communication in V. ammodytes involves less compounds in comparison to the known literature data for other species.
