Chemical Composition and Antioxidant Activity of Ammi visnaga L. Essential Oil.
Kamal FZ, Stanciu GD, Lefter R, Cotea VV, Niculaua M, Ababei DC, Ciobica A, Ech-Chahad A. Kamal FZ, et al. Antioxidants (Basel). 2022 Feb 10;11(2):347. doi: 10.3390/antiox11020347. Antioxidants (Basel). 2022. PMID: 35204230 Free PMC article.
The major components identified were butanoic acid, 2-methyl-, pentyl ester, (Z)-beta-ocimene, D-limonene, linalool, pulegone and lavandulyl-butyrate. The in vitro DPPH and reducing power assays showed moderate to low free radical scavenging activity and the antioxi …

Identification of a male-produced aggregation pheromone in the western flower thrips Frankliniella occidentalis.
Hamilton JG, Hall DR, Kirk WD. Hamilton JG, et al. J Chem Ecol. 2005 Jun;31(6):1369-79. doi: 10.1007/s10886-005-1351-z. J Chem Ecol. 2005. PMID: 16222777
The catch of adult females and males on blue sticky traps was increased by neryl (S)-2-methylbutanoate alone or by a 1:1 blend of (R)-lavandulyl acetate and neryl (S)-2-methylbutanoate, but (R)-lavandulyl acetate was not active alone. This is the first identificatio …

Ho HY, Su YT, Ko CH, Tsai MY. Ho HY, et al. J Chem Ecol. 2009 Jun;35(6):724-32. doi: 10.1007/s10886-009-9649-x. Epub 2009 Jun 16. J Chem Ecol. 2009. PMID: 19529970
Two components were identified from aeration extracts of the virgin female Madeira mealybug, Phenacoccus madeirensis as trans-(1R,3R)-chrysanthemyl (R)-2-methylbutanoate and (R)-lavandulyl (R)-2-methylbutanoate (with a ratio of 3:1) by a combination of gas chromatography r …

Ho HY, Ko CH, Cheng CC, Su YT, Pola S. Ho HY, et al. J Econ Entomol. 2011 Jun;104(3):823-6. doi: 10.1603/ec10374. J Econ Entomol. 2011. PMID: 21735899
Two compounds (trans-1R,3R-chrysanthemyl R-2-methylbutanoate and R-lavandulyl R-2-methylbutanoate) identified from aeration extracts of virgin female Madeira mealybug, Phenacoccus madeirensis Green (Hemiptera: Pseudococcidae), were synthesized and tested in field bioassays …

The female M. hirsutus releases the 2-methylbutanoate of a novel cyclobutanoid monoterpene alcohol (maconelliol) that together with lavandulyl 2-methylbutanoate constitutes the sex pheromone to attract males from a distance. ...Absolute configurations of both naturally occ …
