Embodiment Construction

[0022] The present invention will be more readily understood with reference to the following examples, which are given without limiting the scope of the invention.

[0023] Weigh 50 g of Pingpo seeds, crush them to 100 mesh, then place them in 100 mL of mixed extract solution (volume ratio of methanol, acetone and water: 3.5:3.5:3, and contain 1% formic acid) for 30 min, and repeat the extraction for 2 The second time, filter the extract with two layers of gauze, centrifuge at 7000g for 15min, collect the supernatant, and remove methanol and acetone by vacuum rotary evaporation at 40°C. Then add 2 times the volume of petroleum ether to remove the fat-soluble pigment, repeat 2 times, the obtained liquid is dried under vacuum at 35°C, and the residue is dissolved in 10 mL of ethanol to form a polyphenol ethanol solution.

[0024] It was determined that the total phenolic content of Pingpo seeds was 401.84 μg / mL gallic acid.

[0025] The foregoing descriptions of specific exempl...

Abstract

The invention discloses an extraction method of sterculia nobilis polyphenol. The extraction method of sterculia nobilis polyphenol comprises the following steps: extracting, filtering, centrifuging, rotatably evaporating, removing pigment and purifying. The sterculia nobilis polyphenol extracted by the method is high in content; the extraction method of the sterculia nobilis polyphenol is simple to operate, low in cost and high in efficiency; the method serves as a high-efficiency extraction method suitable for sterculia nobilis polyphenol and can be used for providing reference for industrial production of sterculia nobilis polyphenol.

Description

technical field [0001] The invention belongs to the technical field of agricultural product processing, and in particular relates to a method for extracting syringa polyphenols. Background technique [0002] Pingpo (Sterculia nobilis Smith.) also known as frequency po, cockscomb fruit, water hyacinth fruit, Qijie fruit, Pan'an fruit, also known as Fuguizi in Guangdong, and loquat fruit in southern Fujian, is a common species of Sterculia (Sterculiaceae) Green fruit tree, arbor, originates in southern my country and has a cultivation history of 800 years. It is planted in provinces (autonomous regions) such as Guangdong, Guangxi, Fujian, Yunnan, Guizhou and Taiwan. In addition to China, it is distributed in India, Vietnam, Indonesia, Malaysia, Sri Lanka and Japan. The Pingpo plant is tall and can reach a height of more than 6 meters; the fruit is shaped like a bean pod and contains 1-5 seeds. When it is mature, the pods are cracked and contain seeds, like phoenix eyes slight...
