Insect antifeedants from the Peruvian plant Alchornea triplinervia. Miles, D. Howard; Hankinson, Barbara L.; Randle, Shirley A. (Dep. Chem., Mississippi State Univ., Mississippi State, MS 39762, USA). ACS Symp. Ser., 276(Bioregul. Pest Control), 469-76 (English) 1985. CODEN: ACSMC8. ISSN: 0097-6156. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Section cross-reference(s): 11 The boll weevil antifeedants anthranilic acid [118-92-3], gentisic acid [490-79-9], senecioic acid [541-47-9], trans-cinnamic acid [140-10-3], trans-cinnamaldehyde [14371-10-9], and camphor [76-22-2] were isolated from the Peruvian plant A. triplinervia (Euphorbiaceae). Anthranilic acid and camphor also significantly inhibited the growth of tobacco budworm.

High-performance liquid chromatographic-fluorometric determination of cinnamaldehyde in perfume, cologne and toilet water

High-performance liquid chromatographic-fluorometric determination of cinnamaldehyde in perfume, cologne and toilet water. Wisneski, Harris H.; Yates, Ronald L.; Davis, Henry M. (Div. Cosmetics Technol., Food and Drug Adm., Washington, DC 20204, USA). J. Chromatogr., 317, 421-6 (English) 1984. CODEN: JOCRAM. ISSN: 0021-9673. DOCUMENT TYPE: Journal CA Section: 62 (Essential Oils and Cosmetics) trans-Cinnamaldehyde [14371-10-9] is detd. in fragrances by mixing isooctane and extg. with an aq. soln. of Na 6-aminoicarproate to isolate the aldehyde fraction, dilg. with water, and adding an aliquot of the ext. to a soln. of 1,2-diaminonaphthalene monosulfate in dil. HCO2H. The fluorescent deriv. of cinnamaldehyde, 2-styrylnaphth[1,2-d]imidazole, was prepd. by incubating and then cooling the soln. and adding pyridine. Aliquots were sepd. on a reversed-phase C18 column by using pH 7.8-7.9 (HOAc) THF-H2O contg. triethanolamine and laurylpyridinium chloride. Cinnamaldehyde was detd. by fluorometry (excitation 370 nm, emission 460 nm). Recoveries from various com. fragrances, spiked with 0.01, 0.05, and 0.1% cinnamaldehyde were 94-112% with a mean of 103% and a std. deviation of 5.3. The limit of detection was ~1 ng.
