preparation example 1

[0054] Preparation example 1, the preparation of bamboo shoot extract solid

[0055] Add 1000g of crushed fresh bamboo shoots into a multi-functional extraction tank, add 6 times the weight of bamboo shoots in purified water for reflux extraction, extract twice in total, combine the two extracts, concentrate under reduced pressure to 4g bamboo shoots / ml, and transfer the concentrated solution To the alcohol precipitation tank, add an equal volume of 95% ethanol, let it stand, take the supernatant, concentrate under reduced pressure, and vacuum dry to obtain 100 g of bamboo shoot extract solids, and the extraction yield is 10%.

[0056] The quality inspection standard of the bamboo shoot extract: the free amino acid content is not less than 3.75% (mass percentage).

[0057] Refer to the GBT8314 "Determination of Total Free Amino Acids in Tea" standard to detect the amino acid content in the bamboo shoot extract, and the result: the content is 4.12%.

preparation example 2

[0058] Preparation example 2, the preparation of bamboo shoot extract

[0059]Get 100g of dried yellow bamboo shoots, grind to sieve (200 mesh), add 2000ml of deionized water, heat reflux extraction, extract 3 times, combine all extracts; continue reflux distillation for 40min, collect the distillate to obtain 11ml of bamboo shoot extract.

[0060] The quality inspection standard of bamboo shoot extract is the same as Preparation Example 1. Detected by the same method as Preparation Example 1, the amino acid content in the extract of this example is 3.9%, which meets the quality inspection requirements.

preparation example 3

[0061] Preparation example 3, the preparation of bamboo shoot extract powder

[0062] The same method as Preparation Example 2 was used to obtain 1 L of bamboo shoot extract that met the quality inspection requirements, and the extract was spray-dried at 150° C. to obtain 196 g of yellow powdery extract; the total yield of bamboo shoot extract powder was 19.6%.

[0063] The quality inspection standard of bamboo shoot extract powder is the same as Preparation Example 1. Detected by the same method as Preparation Example 1, the amino acid content in the extract powder of this example is 3.89%, which meets the quality inspection requirements.

[0064] The use of the above bamboo shoot extract is illustrated below with a plurality of formulation preparation examples. The dosage form preparation example is the optimization result of the orthogonal experiment. In the orthogonal experiment: the dosage of hemin iron is set according to the drug dosage standard, and the bamboo shoot ...

Abstract

The invention discloses a composite preparation of extract of bamboo shoots which is used for improving anaemia and a preparation method thereof. The composite preparation is made from the extract of bamboo shoots, iron supplement and other accessory ingredients, wherein, the extract of bamboo shoots is solid, extract liquid or dry powder which is extracted from fresh or dried bamboo shoots by water extraction and alcohol extraction; the iron supplement is ferriporphyrin or heme iron. By adopting the design, the extract of bamboo shoots in the composite preparation of the invention comprising rich glucose, protein and multi elements can stimulate hematopoiesis and expand blood volume and the iron composite preparation thereof has better promotion effect on the recovery of blood loss anemia. By adopting the preparation method of the invention to prepare the extract of bamboo shoot, the process is simple and practical and the various beneficial components in bamboo shoots can be well kept, thus being applicable to commercial production.

Description

Technical field: [0001] The invention relates to the field of medicine, in particular to a composite preparation of bamboo shoot extracts capable of improving anemia and a preparation method thereof. Background technique: [0002] Bamboo shoots are the tender stems of bamboo, a perennial plant in the Gramineae family. They have the characteristics of vigorous growth and are green and pollution-free plants. The varieties of edible bamboo shoots mainly include Moso bamboo shoots, light bamboo shoots, Ci bamboo shoots, etc. Bamboo shoots are fresh and tender, crispy and delicious. They are traditional delicacies in my country and have been eaten for more than 2500 years. Bamboo shoots are rich in nutrients. It is reported in the literature that bamboo shoots contain iron, calcium, phosphorus and other mineral nutrients and vitamins, as well as various proteins. After protein hydrolysis, 18 kinds of amino acids can be obtained, and the fat content is low (Liu Mingchi. The nutri...
