Biotransformation of new enol phosphate insecticides

Biotransformation of new enol phosphate insecticides. III. Metabolism of bromfenvinphos in plants. Gwiazda, Maria (Pol.). Organika, 140-54 (Polish) 1977. CODEN: ORGAD2. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemicals) Two wk after injection of 14C-labeled bromfenvinphos (I) [33399-00-7] into leaf petioles of beans, I, Et2HPO4 [598-02-7], EtH2PO4 [1623-14-9], ethylbromfenvinphos (II) [64654-12-2] , a II conjugate, 2,4-dichlorophenacyl bromide [2631-72-3], 1-(1-hydroxy-2-bromoethyl)-2,4-dichlorobenzene [53066-15-2], epoxyethyl-2,4-dichlorobenzene [13692-15-4], 2,4-dichloroacetophenone [2234-16-4], 2,4-dichlorobenzaldehyde [874-42-0], 1-(1-hydroxyethyl)-2,4-cichlorobenzene glucoside conjugate [67305-77-5], 2,4-dichloromandelic acid [7554-78-1], 2,4-dichlorobenzyl alc. [1777-82-8], 2,4-dichlorobenzoic acid [50-84-0], and unidentified products recovered from the entire plant contained 22.39, 0.01, 0.07, 0.78, 3.0, 0.06, 3.5, 3.8, 0.74, 5.2, 0.87, 0.41 0.10, 3.76, and 8.68%, resp., of the injected 14C. The total recovery of 14C was 53.37% of the originally injected amt., indicating excretion of gaseous metabolites or exudation by roots. I was metabolized by hydrolysis and O-dealkylation. Potatoes metabolized I more slowly than did beans, and translocated a larger proportion to roots. I metabolites also were recovered from potato tubers.

Determination of aromatic alcohols in cosmetic products using reversed-phase high-performance liquid chromatography

Determination of aromatic alcohols in cosmetic products using reversed-phase high-performance liquid chromatography. Gagliardi, L.; Amato, A.; Cavazzutti, G.; Zagarese, V.; Gattavecchia, E.; Tonelli, D. (Ist. Super. Sanita, Rome, Italy). J. Chromatogr., 294, 442-6 (English) 1984. CODEN: JOCRAM. ISSN: 0021-9673. DOCUMENT TYPE: Journal CA Section: 62 (Essential Oils and Cosmetics) Good resoln. of a std. mixt. of benzyl alc. [100-51-6], 2-phenoxyethanol [122-99-6], 1-phenoxy-2-propanol [770-35-4], 3,4-dichloro [1805-32-9] and 2,4-dichlorophenylmethanol [1777-82-8] and Et 4-hydroxybenzoate [120-47-8] internal std. was achieved by reversed-phase HPLC using an RP-18 column, MeCN-H2O () as mobile phase, 1 mL/min flow rate, 350 column temp., and 230 nm for detection. Linearity was obsd. up to 20 mg injected for PhCH2OH and up to 6 mg injected for the other alcs. Five cosmetic products were subjected to HPLC and quant. recoveries and excellent precision for added mixts. of the alc. preservatives were obtained.
