Embodiment 1

[0043] Embodiment 1, delicacy boletus aqueous extract freeze-dried powder is to the reducing effect of nitrite content in rat blood

[0044] One, the preparation of delicious boletus extract

[0045] Take 500g of fruiting bodies frozen at -20°C for one year, add 500ml of distilled water, thaw at 15-25°C, grind to 50-65 mesh with a tissue grinder at 4°C, and extract at 4°C for 30 minutes. The extract was centrifuged at 8000g at 4°C for 15min, and the obtained supernatant (750ml) was the water extract of Boletus deliciosa, and 1.5ml of the water extract of Boletus deliciosa was obtained per gram of fruiting body of Boletus deliciosa.

[0046] Freeze the water extract of delicious boletus at -80°C, and then freeze-dry it with a lyophilizer to obtain 25,000 mg of delicious boletus water extract freeze-dried powder, with an average of 50 mg of delicious boletus fruiting body per gram of delicious boletus Aqueous extract lyophilized powder.

[0047] 2. The effect of freeze-dried p...

Embodiment 2

[0055] Embodiment 2, delicacy boletus (Boletus edulis) water extract freeze-dried powder capsule is to the reduction effect of nitrite content in rat blood

[0056] The delicious boletus water extract freeze-dried powder that step 1 obtains in embodiment 1 is filled boletus gelatin capsule, and each boletus gelatin capsule on average contains 0.02g delicious boletus water extract freeze-dried powder, obtains delicious boletus water Extract freeze-dried powder capsule.

[0057]Taking 30 male SD rats with a body weight of 200-220 g as experimental materials, the 30 male SD rats were randomly divided into two groups, each group having 15 male SD rats, namely the experimental group and the control group.

[0058] Each male SD rat of the experimental group is fed with 2 delicious boletus water extract freeze-dried powder capsules, and the oral dose is 18.2-20mg delicious boletus water extract freeze-dried powder / 100g body weight (with implementation The intragastric dose of the lo...

Abstract

The invention discloses application of boletus edulis in reduction of nitrite in animal blood, and particularly relates to an application of boletus edulis in preparation of products for reducing the content of nitrite in animal blood. The boletus edulis extract disclosed by the invention is a water soluble substance extracted from the sporocarp of boletus edulis by water. Experiments prove that boletus edulis aqueous extract lyophilized powder is capable of remarkably reducing the content of nitrite in rat blood; and boletus edulis aqueous extract lyophilized powder capsules have a good pharmacodynamic effect on reducing the content of nitrite in rat blood. The boletus edulis aqueous extract lyophilized powder or the boletus edulis aqueous extract lyophilized powder capsules can be used for reducing the content of nitrite in animal blood.

Description

technical field [0001] The invention relates to the application of boletus deliciosa extract in reducing the content of nitrite in animal blood in the biological field. Background technique [0002] Nitrite is a class of nitrite ion (NO 2 - ) is an inorganic compound, white or light yellow crystalline salt substance, bitter in taste, and looks very similar to table salt. Nitrite is an important intermediate substance in the nitrogen cycle in nature and widely exists in the human living environment. Fruits and vegetables contain nitrite, as do seawater, groundwater, and tap water. Moreover, with the aggravation of environmental pollution and the excessive use of nitrogen fertilizer, the content of nitrite in agricultural products is increasing day by day. As a food additive allowed to be used, nitrite is widely used in meat products. It can combine with myoglobin in meat products to maintain a good color appearance. In addition, pickled foods and fermented foods are Ferm...
