Structure and effects of mustelid ecomones. IV. Analysis of behaviorally active glandular secretions of the badger (Meles meles L.). Schildknecht, Hermann; Hiller, Hans (Org.-Chem. Inst., Univ. Heidelberg, Heidelberg D-6900, Fed. Rep. Ger.). Chem.-Ztg., 108(1), 1-5 (German) 1984. CODEN: CMKZAT. 373-49-9 and 40238-46-8 are cas registry numbers of chemicals which are used as reagents here. ISSN: 0009-2894. DOCUMENT TYPE: Journal CA Section: 2 (Mammalian Hormones) In the subcaudal gland secretion of male or female badger, which has a function in that it is used to mark territory and prey, as well as other roles in chem. communication, the following fatty acids were identified: propionate [79-09-4], isobutyrate [79-31-2], butyrate [107-92-6], 2-methylbutyrate [116-53-0], isovalerate [503-74-2], valerate [109-52-4], isocaproate [646-07-1], capryllate [124-07-2], and methylnonanoate [1731-84-6]. These fatty acids were in the foul-odor fraction of the secretion, and the odor of the anal gland secretion was also caused by lower fatty acids. However, lipophilic substances, esp. higher satd. and unsatd. fatty acids, were also present in both subcaudal and anal gland secretions. The following ketones were also identified in anal gland secretions: 3-butylnonan-2-one [58766-10-2], 3-butylundecan-2-one [89355-10-2], 3-butyltridecan-2-one [89355-11-3], and 3-butylpentadecan-2-one [89355-12-4]. .

Determination of volatile fatty acids and lactic acid in silage by gas chromatography and identification of unknown component

Determination of volatile fatty acids and lactic acid in silage by gas chromatography and identification of unknown component. Kitada, Yoshimi; Sasaki, Michiko; Tanigawa, Kaoru; Shimizu, Satoru; Nagatani, Kenzaburo (Nara Prefect. Inst. Public Health, Nara, Japan). Nippon Shokuhin Kogyo Gakkaishi, 31(1), 44-6 (Japanese) 1984. CODEN: NSKGAX. ISSN: 0369-5727. DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) The simultaneous quant. detn. of 9 kinds of volatile fatty acids (AcOH [64-19-7], propionic acid [79-09-4], iso-butyric acid [79-31-2], butyric acid [107-92-6], iso-valeric acid [503-74-2], valeric acid [109-52-4], iso-caproic acid [646-07-1], caproic acid [142-62-1], and caprylic acid [124-07-2]), lactic acid [50-21-5], and furfural [98-01-1] in silage was investigated by gas chromatog. They were sepd. within 16 min. on a 1.5 m 1% KT-300 on Chromatobase AF, 40-60 mesh glass column. Column temp. was elevated from 120 to 190° (5°/min.). 109-52-4 and 79-09-4 which are cas registry numbers are also used here. With the std. method it is necessary to add 0.05-0.10% H2SO4 to the aq. ext. from silage since a terephthalic acid solid support is used. H2SO4 addn. was not necessary with this column. The coeff. of variation for these components ranged 2.08-2.74%. An unknown component in brewers' grain silage ext. was identified as furfural with GC-MS. .
