Embodiment Construction

[0050] The content of the present invention is further explained or illustrated through specific embodiments below, but the examples should not be construed as limiting the protection scope of the present invention.

[0051] Polyphenols are an important group of phenols, and their special chemical structure leads to their unique physiological activity and ecological significance. Especially in natural plants, polyphenols, as self-protective secondary metabolites, have a The food intake of animals is of great significance.

[0052] Polyphenols in plants can combine with proteins in the oral cavity by hydrogen bonds or hydrophobic bonds. When the content of polyphenols in the oral cavity is high, oral epithelial cells are stimulated to produce a series of complex changes such as shrinkage and wrinkling. When it is eaten, it produces a bad taste, that is, astringent taste, which reduces the palatability of food; at the same time, polyphenols can reduce the digestion rate of anima...

Abstract

The invention provides a method for measuring the content of polyphenols in fargesia denudate. The method comprises three steps: drawing a standard curve by using gallic acid as a polyphenols standard substance, preparing a sample solution of the polyphenols in the fargesia denudate, and measuring the content of the polyphenols in a fargesia denudate sample. The method provided by the invention is low in detection limit, high in accuracy, good in repeatability and high in precision.

Description

technical field [0001] The invention relates to the field of analytical chemistry, in particular to a method for determining the content of polyphenols in arrow bamboo by the Folin phenol method. Background technique [0002] Known as the "living fossil", the giant panda is a first-class protected animal in my country and a flagship species of wild animal protection in the world. With the change of the environment and thousands of years of evolution and adaptation, it has gradually transformed into a species dominated by subalpine bamboos. The staple food of herbivorous animals, the staple food bamboo is Arrow bamboo. [0003] Bamboo, the staple food of giant pandas, contains a relatively high content of polyphenols. Researchers believe that plant polyphenols can prevent animals from eating and reduce their digestibility. Therefore, the content of polyphenols in bamboo will affect the diet of giant pandas. Feed utilization and feed intake, but at present, researchers have li...
