Embodiment 1

[0031] (1) Gather fresh Echinacea purpurea root and rhizome 50g, and clean it;

[0032] (2) Set up steam equipment, add appropriate amount of water (the water is about 5cm high) in an ordinary iron pot (diameter 18cm, height 20cm), set up a steaming grid at a distance of 5cm from the water surface and spread gauze, and cover the pot . Put the pot on the electric stove to heat, and insert the thermometer through the small hole of the pot cover, and the thermometer does not touch the water surface. If there is a gap, it can be sealed with wet gauze. The same effect can also be achieved by using a water bath, and it is more convenient.

[0033] (3) When the steam temperature rises to 98-99°C, wait for about 3 minutes. Spread the echinacea material evenly into the steamer in the pot, seal it, and steam it for 15 minutes;

[0034] (4) Take out the medicinal materials, and place the materials in a cool and dry environment to dry for 7 days;

[0035] (5) Collect and arrange the ...

Embodiment 2

[0038] (1) Gather fresh Echinacea purpurea root and rhizome 100g, and clean it;

[0039] (2) Set up steam equipment, add appropriate amount of water (the water is about 5cm high) in an ordinary iron pot (20cm in diameter, 20cm in height), set up a steaming grid at a distance of 5cm from the water surface and spread gauze, and cover the pot . Put the pot on the electric stove to heat, and insert the thermometer through the small hole of the pot cover, and the thermometer does not touch the water surface. If there is a gap, it can be sealed with wet gauze. The same effect can also be achieved by using a water bath, and it is more convenient.

[0040] (3) When the steam temperature rises to close to 100°C (about 98°C-99°C), wait for about 3-5 minutes. Spread the echinacea material evenly into the steamer in the pot, seal it, and steam it for 15 minutes;

[0041] (4) Take out the medicinal materials, and place the materials in a cool and dry environment to dry for 5 days;

Embodiment 3

[0044] Embodiment 3 Comparative Test 1

[0045] Harvest 100g of fresh Echinacea purpurea roots and rhizomes of two kinds of growth years respectively. After cleaning, divide each material into two parts with equal quality at random, each with an average of 50g. Each part of the material is steam treated with the method of the present invention (100° C. steam, 15 min), and then dried in the air, and the other two parts are then directly dried. The comparison results of the content of cichoric acid are shown in Table 1.

Abstract

The invention discloses a postharvest processing method for increasing chicoric acid content of echinacea. The method adopts high-temperature hot steaming treatment to kill the activity of polyphenol oxidase and ensure that the polyphenol oxidase cannot oxidize or degrade polyphenol compounds in Echinacea materials so as to raise the retention rate of polyphenol compounds, namely chicoric acid. The method can effectively kill enzymic activity to enable the polyphenol compounds in the materials to be retained in large quantities, can double the retention rate of chicoric acid compared with a conventional in-shade drying method, is simple to operate, not high in requirements for equipment and low in operation cost, can be widely used in the field of Echinacea postharvest processing, and raises the utilization rate of medicinal plant resources.

Description

technical field [0001] The invention belongs to the technical field of post-harvest raw material processing and storage application of medicinal plants, and in particular relates to a post-harvest processing method for increasing the content of cichoric acid in Echinacea purpurea. Background technique [0002] Cichoric acid is one of the main medicinal components with the most abundant content in Echinacea purpurea, and polyphenol oxidase in fresh medicinal materials is the main internal factor affecting the retention rate of cichoric acid in Echinacea purpurea. [0003] At present, in the post-harvest treatment methods of Echinacea purpurea, the method of drying at room temperature and drying in the shade at room temperature is generally used simply to achieve the purpose of storing Echinacea purpurea materials, which is not conducive to the retention of the content of the medicinal component cichoric acid in the materials. There are also experiments showing that the retent...
