Embodiment 1

[0020] Embodiment 1 A method for rapidly detecting antioxidant components in rhubarb seeds, comprising the following steps:

[0021] (1) After crushing rhubarb seeds to 40 mesh, rhubarb seed powder is obtained.

[0022] (2) The rhubarb seed powder was ultrasonically extracted with 50 times its mass of methanol with a volume concentration of 50% under the condition of a power of 200W for 50 minutes, and the rhubarb seed extract was obtained after filtration.

[0023] (3) The rhubarb seed extract is separated by a high-performance liquid chromatography column, and the separated components first flow through the first ultraviolet detector as a sample. The mass concentration of the sample and the second pump as the mobile phase is 10 mg / After the antioxidant 1,1-diphenyl-2-trinitrophenylhydrazine of L is derivatized in the reaction loop, it enters the second UV detector, and then the first UV detector and the second UV detector The recorded chromatograms are compared, and when a...

Embodiment 2

[0028] Embodiment 2 A method for rapidly detecting antioxidant components in rhubarb seeds, comprising the following steps:

[0029] (1) After crushing rhubarb seeds to 60 mesh, rhubarb seed powder is obtained.

[0030] (2) The rhubarb seed powder was ultrasonically extracted for 30 min with 100 times its mass of methanol with a volume concentration of 80% under the condition of a power of 300 W, and the rhubarb seed extract was obtained after filtration.

[0031] (3) The rhubarb seed extract is separated by a high-performance liquid chromatography column, and the separated components first flow through the first ultraviolet detector as a sample. The mass concentration of the sample and the second pump as the mobile phase is 100 mg / After the antioxidant 1,1-diphenyl-2-trinitrophenylhydrazine of L is derivatized in the reaction loop, it enters the second UV detector, and then the first UV detector and the second UV detector The recorded chromatograms are compared, and when an...

Embodiment 3

[0036] Embodiment 3 A method for rapidly detecting antioxidant components in rhubarb seeds, comprising the following steps:

[0037] (1) After crushing rhubarb seeds to 40 mesh, rhubarb seed powder is obtained.

[0038] (2) The rhubarb seed powder was ultrasonically extracted with 100 times its mass of 100% methanol at a power of 300W for 30 minutes, and filtered to obtain rhubarb seed extract.

[0039] (3) The rhubarb seed extract is separated by a high-performance liquid chromatography column, and the separated components first flow through the first ultraviolet detector as a sample. The mass concentration of the sample and the second pump as the mobile phase is 200 mg / After the antioxidant 1,1-diphenyl-2-trinitrophenylhydrazine of L is derivatized in the reaction loop, it enters the second UV detector, and then the first UV detector and the second UV detector The recorded chromatograms are compared, and when an inverted peak compound appears in the chromatogram recorded b...

Abstract

The invention relates to a method for rapidly detecting antioxidant ingredients in rhubarb seeds. The method comprises the following steps: (1) crushing the rhubarb seeds to obtain rhubarb seed powder; (2) extracting the rhubarb seed powder by using methanol, and filtering to obtain a rhubarb seed extracting solution; (2) performing chromatographic column separation on the rhubarb seed extracting solution by using a high performance liquid chromatography, enabling the separated ingredients to flow through a first ultraviolet detector to serve as a sample, deriving the sample and an antioxidant, namely 1,1-biphenyl-2trinitrobenzene hydrazine which is pumped, serves as a mobile phase in a second pump and has the mass concentration of 10-200mg / L in a reactive loop, enabling the product to enter a second ultraviolet detector, and comparing chromatogram maps recorded by the first ultraviolet detector and the second ultraviolet detector, wherein when a compound with a negative peak occurs in the chromatogram map recorded by the second ultraviolet detector, the compound is the antioxidant ingredient in the extract. The method is simple and rapid, and the antioxidant ingredients in rhubarb seeds can be effectively evaluated.

Description

technical field [0001] The invention relates to a method for rapidly detecting antioxidant components, in particular to a method for rapidly detecting antioxidant components in rhubarb seeds. Background technique [0002] The traditional Chinese medicine rhubarb is the dried root and rhizome of Rheum tanguticum Maxim. ex Balf ., Rheum palmatum Linn. Tangut rhubarb, also known as Junmuzha (Tibetan name), or rhubarb with chicken feet, belongs to the authentic medicinal materials in Qinghai Province. There are also distributions in the northwest of Sichuan. Rhubarb palmatum is mainly produced in Gansu, Qinghai, Tibet, Sichuan and other places. It is mainly cultivated and has the largest yield. Medicinal rhubarb is mainly produced in Sichuan, Guizhou, Yunnan, Hubei, Shaanxi and other places, cultivated or wild. [0003] The seeds of medicinal materials are the source of production and development of medicinal materials, the internal factors that determine the quality of Chine...
