Abstract

The invention relates to a method for quantitative analysis of p-coumaric acid. The method utilizes a H2SO4-KIO3-[NiL](ClO4)2-MA(malonic acid)-H2O2 non-linear chemical oscillation system as a detection solution, builds a working curve according to p-coumaric acid oscillatory response in detection and realizes quantitative analysis of p-coumaric acid. In the [NiL](ClO4)2, L represents 5, 7, 7, 12, 14, 14-hexamethyl-1, 4, 8, 11-tetraazacyclotetradecyl-4, 11-diene. The quantitative analysis method of the p-coumaric acid has the characteristics of high accuracy, operation easiness, convenience and fastness.

Description

1. Technical field [0001] The present invention relates to a kind of analytical detection method, specifically a kind of nickel complex [NiL] (ClO 4 ) 2 Method for the detection of p-coumaric acid in a catalytic nonlinear oscillatory system. 2. Background technology [0002] P-coumaric acid, also known as p-hydroxycinnamic acid, has a structure as shown in formula (I), and is widely found in natural plants, especially in leguminous plants. p-Hydroxycinnamic acid is widely used in medicine, food, daily necessities, feed chemical industry and other fields. In terms of medicine, a large number of studies have shown that p-hydroxycinnamic acid has strong biological activities, such as anti-oxidation, anti-tumor, anti-chemotherapy, whitening, etc., and it is also an active ingredient of choleretic. It is similar, and has the advantages of moderate and long-lasting effect. It can also be used as an intermediate in the production of coronary heart disease treatment drug, cxinidi...
