1986: A rapid and simultaneous determination of saccharin benzoic acid sorbic acid and six esters of p hydroxybenzoic acid in liquid foods by high performance liquid chromatography Journal of Japanese Society of Food Science and Technology 33(7): 514-518 Matsunaga, A.; Yamamoto, A.; Makino, M...
Gallic acid (2,3,4-trihydroxybenzoic acid) is a natural phenolic compound; therefore, determination of trace gallic acid is very important. In this work, a novel, sensitive and reliable method was developed using differential pulse polarography. The most suitable buffer system was found to be ...
Plant regeneration and biochemical accumulation of hydroxybenzoic and hydroxycinnamic acid derivatives in Hypoxis hemerocallidea organ and callus cultures Micropropagation of Hypoxis hemerocallidea Fisch. and C.A. Mey was used as a model system to study the influence of cytokinins (CKs) on plant rege...
Determination of Dissociation Constants of Some Hydroxylated Benzoic and Cinnamic Acids in Water from Mobility and Spectroscopic Data Obtained by CE-DAD In this study, the dissociation constants of a series of phenolic acids, including benzoic acid, four hydroxylated derivatives (p-hydroxybenzoic, protoc...
The limits of determination were 0.2 µg · mL−1 for shikimic acid, 20 µg · mL−1 for quinic acid, 0.3 µg · mL−1 for chlorogenic acid, 0.5 µg · mL−1 for rosmarinic acid, 0.3 µg · mL−1for p-hydroxybenzoic acid ...
