Volatile oil composition of <i>Carthamus Tinctorius</i> L. flowers grown in Kazakhstan

Floral volatiles identification and molecular differentiation of Osmanthus fragrans by neutral desorption extractive atmospheric pressure chemical ionization mass spectrometry

“…Three peaks at m/z 99.0802 (C 6 H 11 O + ), m/z 97.0646 (C 6 H 9 O + ), and m/z 187.1325 (C 10 H 19 O 3 + ) were obtained mainly in the cultivars of “liuyedangui” and “zhushadangui”, and could be assigned, respectively, to protonated 2‐hexenal, 2‐ethylfuran, and epoxy‐linalool oxide . In a similar procedure, other peaks at m/z 71.0489 (C 4 H 7 O + ), m/z 81.0696 (C 6 H 9 + ), m/z 93.0697 (C 7 H 9 + ), m/z 123.1166 (C 9 H 15 + ), and m/z 175.1478 (C 13 H 19 + ) were tentatively assigned as protonated 3‐buten‐2‐one, cyclohexadiene, toluene, 3‐allylcyclohexene, and 6‐ethyl‐2‐methyl‐decane, respectively, based on their high‐resolution and CID data (Table ). Our results demonstrate that ND‐EAPCI‐MS spectra provide rich chemical information about the inter‐cultivar differences between plants at the VOC level.…”

“…Nine of the reported VOCs, 3‐buten‐2‐one, cyclohexadiene, 2‐methylfuran, 3‐allylcyclohexene, cuminyl alcohol, hotrienol oxide, epoxy‐linalol oxide, N ‐(2‐hydroxyethyl) octanamide, and 3‐hydroxy‐dihydro‐β‐ionone, have not been identified in O. fragrans flowers in previous GC/MS studies . The identities of these nine new chemicals were tentatively assigned based on their exact masses, collision‐induced dissociation (CID) product ion spectra, and literature MS search for the VOCs reported from other plant flowers …”

“…2,7,[9][10][11]25 The identities of these nine new chemicals were tentatively assigned based on their exact masses, collision-induced dissociation (CID) product ion spectra, and literature MS search for the VOCs reported from other plant flowers. [26][27][28][29][30][31][32][33] Although there are apparent differences in the floral fragrance of the studied cultivars, their "core" osmanthus fragrance could still be clearly distinguished by nose in every cultivar. Therefore, it is reasonable to believe that the chemicals responsible for the "core" floral fragrance will be emitted by every cultivar.…”

Induction of biochemical active constituents of Jojoba (Simmondsia chinensis (Link) Schneider) callus affected by hormones

“…Aristolene with the following biological activity: has a smell that attracts predators and wolves (Scrivner et al, 1984), is an antibiotic bacterium, Bacillus, and is used for throat congestion (Zour), it is anti-inflammatory, the cradle of the nerves (Tian-Shung et al, 2004), pain reliever and has luminous bacteria (Shimomura et al, 1974); 4. 7-Hexadecenal with the following biological activity: used for treating patients with diabetes, by increasing the secretion of insulin in the body (Turgumbayeva et al, 2015), it is found in the liver of sheep and thus attractive to wolves and used in hunting wild animals (Scrivner et al, 1984), has Luminous Bacteria "Aldehydeless" Dark Mutant (Shimomura et al, 1974); 5. Tricosene which has kairomone effect (Ananthakrishnan et al, 1991).…”

“…These major active constituents are divided into five fractions: 1. 1-Hexadecanol which has the following biological activity: a composite medium used in the synthesis of other compounds (Turgumbayeva et al, 2015), has flavors and smells like composite simmondsin (Scrivner et al, 1984) and has luminous bacteria (Shimomura et al, 1974); 2. nonadecatriene compound acting as pheromone that attracts male insects (Nilsson, 2009); 3. Aristolene with the following biological activity: has a smell that attracts predators and wolves (Scrivner et al, 1984), is an antibiotic bacterium, Bacillus, and is used for throat congestion (Zour), it is anti-inflammatory, the cradle of the nerves (Tian-Shung et al, 2004), pain reliever and has luminous bacteria (Shimomura et al, 1974); 4.…”
