Description

Medicinal and edible dual-purpose composition for resisting helicobacter pylori and application thereof
Technical Field
The invention belongs to the field of food therapy and health care products, and particularly relates to a helicobacter pylori resistant medicine-food dual-purpose composition and application thereof.
Background
About half of the world's population is currently infected with H.pylori (Hp). Hp infection causes diseases of the digestive tract such as gastritis and gastric and duodenal ulcers, and is one of the major risk factors for the development of gastric cancer. Many studies have shown that eradication of Hp can significantly reduce the incidence of gastric cancer. Currently, the world health organization recommends a treatment regimen for Hp infection by triple or quadruple therapy, i.e. the simultaneous administration of a proton pump inhibitor (omeprazole, etc.) plus two antibiotics (two selected from clarithromycin, amoxicillin, tetracycline, metronidazole, etc.) or a bismuth agent (bismuth potassium citrate, etc.) plus a proton pump inhibitor plus two antibiotics. However, with the long-term use of antibiotics, Hp is likely to generate different degrees of drug resistance to antibiotics, which results in failure of radical treatment of triple or quadruple therapy, and also often causes side effects such as dysbacteriosis, and the like, thus increasing the burden of patients. For refractory gastritis, gastric ulcer and the like caused by drug-resistant helicobacter pylori infection, the treatment by using antibiotics generating drug resistance is not suitable, the antibiotics are required to be adjusted, but few candidate antibiotics effective to the helicobacter pylori exist, and a new scheme is urgently required to be explored.
The production of a large amount of highly active urease is one of the biological properties of Hp. Urease hydrolyzes urea to generate ammonia, and an 'ammonia cloud' protective layer is formed around the thalli to resist the killing effect of gastric acid. Therefore, urease plays a role in colonization and toxicity in H.pylori infection and is also an important target for the treatment of H.pylori. Thus, the screening of the inhibitor for resisting Hp urease has great application prospect in resisting helicobacter pylori.
The theory of homology of medicine and food (also called as homology of medicine and food) exists in traditional Chinese medicine since ancient times, and the theory of homology of medicine and food means that many foods, namely medicines, can prevent and treat diseases like the foods and the medicines, and have wide application in daily health preservation and clinical treatment. Based on the antibacterial activity, the medicine and food dual-purpose composition is screened and prepared from the antibacterial activity, the growth of the helicobacter pylori and the activity of urease are inhibited, the aim of daily prevention or treatment of stomach diseases caused by helicobacter pylori infection is fulfilled, a theoretical basis is provided for application of traditional Chinese medicinal materials in resisting the helicobacter pylori, and a reference is provided for better clinical application of the traditional Chinese medicine.
Disclosure of Invention
The technical problem to be solved is as follows: the invention aims to overcome the defects of the prior art, and provides a helicobacter pylori resistant composition used as both medicine and food and an application thereof, namely a ginger extract, a sophora flower bud extract and a mulberry leaf extract, by adopting a natural plant extract used as both medicine and food as a raw material according to the principle of 'homology of medicine and food' of Chinese medical science food therapy.
The technical scheme is as follows: a medicine and food dual purpose composition for resisting helicobacter pylori is composed of the following raw materials by weight: 3-10 parts of ginger extract, not more than 3 parts of sophora flower bud extract and not more than 5 parts of mulberry leaf extract.
Preferably, the composition comprises 3-7 parts of ginger extract, 1-3 parts of sophora flower bud extract and 1-5 parts of mulberry leaf extract in parts by weight.
The composition can be used for preparing food and health product for preventing or treating digestive tract diseases caused by helicobacter pylori infection.
The composition can be made into tablet, capsule, pill, granule or powder.
Has the advantages that: the composition can be used for preparing medicines for preventing or treating stomach diseases such as acute and chronic gastritis, gastric ulcer, duodenal ulcer and the like caused by drug resistance or sensitive helicobacter pylori infection, and has small toxic and side effects and low medical cost. The composition has reasonable compatibility, has better inhibiting effect on helicobacter pylori antibiotic sensitive strains and drug-resistant strains, effectively inhibits the activity of helicobacter pylori urease, has the action characteristics of multiple components, multiple ways and multiple targets, and is suitable for Hp infected persons. In conclusion, the application of the composition can reduce the use of antibiotics so as to effectively relieve the problem of helicobacter pylori resistance.
