Embodiment 1

[0013] Embodiment 1: the preparation of total flavonoids extract of orange red

[0014] The preparation method of the total flavonoid extract of Huajuhong is as follows: take the medicinal material of Huajuhong, decoct it with water, filter it, concentrate the decoction to a relative density of 1.05-1.30, add ethanol or (and) methanol for alcohol precipitation, and precipitates appear , filtered, and the filtrate was recovered from alcohol to an alcohol-free extract, and water was added to adjust the relative density to 1.05-1.15. After standing for more than 3 days, a precipitate was precipitated, filtered, and the precipitate was obtained. Drying is the extraction of total flavonoids of Huajuhong thing.

[0015] The method for determining the total flavonoid content of the total flavonoids extract of Huajuhong is as follows: the content is determined by the method contained in the first part of the "Chinese Pharmacopoeia" 2010 edition under the item of Huajuhong. That is, t...

Abstract

The invention relates to novel application of an exocarpium extract. The invention discloses application of an exocarpium total flavone extract to preparation of a medicine for preventing and treating PM2.5 particle-induced acute attack of a chronic obstructive pulmonary disease, a medicine for preventing and treating airflow limitation aggravation during an acute aggravation attack period of the chronic obstructive pulmonary disease, and a medicine for preventing and treating a high-airway reactivity and low-lung dynamic compliance disease of a respiratory system for the first time. Preferably, the exocarpium total flavone extract with the total content of flavone compounds being higher than 50% is used. Compared with the prior art, the invention has the advantages as follows: the exocarpium total flavone extract is simple in preparation method, low in cost and accurate in therapeutic effect; the exocarpium total flavone extract is a natural plant extract, is free of side effects, and can be used as preventive health food or therapeutic medicines.

Description

technical field [0001] The present invention relates to a new application of the citrus red extract, in particular to the use of the citrus red extract for preparing a medicine for preventing and treating the acute exacerbation of chronic obstructive pulmonary disease induced by PM2.5. Background technique [0002] Chronic obstructive pulmonary disease (COPD) is a common disease characterized by persistent airflow limitation. Airflow limitation develops progressively and is associated with an increased chronic inflammatory response of the airways and lungs to noxious particles or gases. COPD is one of the diseases with the highest morbidity and mortality worldwide, and has become an important public health problem. There are currently 600 million people in the world suffering from COPD; according to the "Chinese Resident Nutrition and Chronic Disease Status Report (2015)", the prevalence of COPD among people aged 40 and over in my country is as high as 9.9%. [0003] The 2...
