Quantitative determation by the enzymic method. (Toyo Jozo Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 59063198 A2 10 Apr 1984 Showa, 54 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C12Q001-26; C12Q001-34; G01N033-50. APPLICATION: JP 82-173569 1 Oct 1982. DOCUMENT TYPE: Patent CA Section: 9 (Biochemical Methods) Section cross-reference(s): 4, 7 An enzymic-colorimetric method for the quant. detn. of I (where R1 = OH or NH2; R2, R3, R4, R5, R6 = H, halogen, lower alkyl, lower alkoxy, NH2, substituted amino, OH, carboxy; sulfo; R5 and R6 may form a linkage) is described. I is reacted with its complex in the presence of an oxidase (ascorbic acid oxidase [9029-44-1], laccase [80498-15-3], tyrosinase [9002-10-2]) and the reaction mixt. is analyzed by colorimetry for the detn. of I. Complexes such as 1-naphthol-2-sulfonic acid [567-18-0], phenol [108-95-2], 2,5-dimethylphenol [95-87-4], o-methylaniline [95-53-4], m-methylaniline [108-44-1], 4-chloro-1-naphthol [604-44-4], cleve's acid [51548-48-2], 1-hydroxy-2-naphthoic acid [86-48-6], o-chlorophenol [95-57-8], m-aminophenol [591-27-5], m-phenylenediamine [108-45-2], 2,6-dibromophenol [608-33-3], 2,6-dimethoxyphenol [91-10-1], 3,5-dimethylphenol [108-68-9], 2,6-dimethylphenol [576-26-1], 2,4-dimethylphenol [105-67-9], 2,3-dimethylphenol [526-75-0], 2,5-dimethylphenol [95-87-4], anthranilic acid [118-92-3], N,N-dimethylaniline [121-69-7], aniline [62-53-3], m-chloroaniline [108-42-9], o-aminophenol [95-55-6], 2-naphthol [135-19-3], m-bromoaniline [591-19-5], N,N-ethylhydroxyethylaniline [92-50-2], m-chlorophenol [108-43-0], p-chlorophenol [106-48-9] and p-bromophenol [106-41-2] can be used.There are some reagents like 9029-44-1 is used in this study. Thus, a sample contg. 2,6-dibromo-4-aminophenol [609-21-2] was treated with K 1-naphthol-2-sulfonate [832-49-5] in the presence of ascorbic acid oxidase at 37° for 10 min and the reaction mixt. was analyzed at 630 nm for the detn. of 2,6-dibromo-4-aminophenol. Based on these methods, activities of a-glucosidase [9001-42-7], cystine aminopeptidase [9031-41-8], a-chymotrypsin [9004-07-3], trypsin [9002-07-7], a-amylase [9000-90-2], alk. phosphatase [9001-78-9], esterase [9013-79-0] and endotoxin was detd. .
