Abstract

A method for extraction and content determination of lignan components of Chinese magnoliavine fruit belongs to the technical field of preparation of effective components of Chinese magnoliavine fruit. To solve the problem of low extraction efficiency of lignan components in Chinese magnoliavine fruit, the invention provides a method for extraction of lignan components, which comprises the following steps: 1) mixing Chinese magnoliavine fruit with ethyl acetate in a solid-to-liquid ratio of 1 g:(1.5-6) mL, carrying out extraction with a flash extractor for 1 to 6 times, 30 to 100 seconds eachtime, and putting the extracts together; 2) concentrating the extract from the step 1) and then removing ethyl acetate to obtain an extract; and 3) subjecting the extract to silica-gel column chromatography and subsequent gradient elution, thereby obtaining the lignan components of Chinese magnoliavine fruit. The invention also provides a method for simultaneous determination of lignan componentsof Chinese magnoliavine fruit by high performance liquid chromatography. The method for extraction and content determination of lignan components of Chinese magnoliavine fruit is suitable for deep processing of Chinese magnoliavine fruit.

Description

Technical field

[0001] The invention belongs to the technical field of preparation of schisandra active ingredients, and specifically relates to a method for extraction and content determination of schisandra lignans. Background technique

[0002] Schisandra is a plant widely recognized in traditional Chinese medicine and modern Chinese medicine. It belongs to the Magnoliaceae and is the dried and mature fruit of Schisandra. It has been a precious Chinese medicinal material since ancient times. Schisandra has the effects of replenishing qi, solidifying surface and antiperspirant, and is often used in clinical applications to treat gastrointestinal diseases, respiratory failure, cardiovascular diseases and other types of diseases. Schisandra contains a variety of chemical components, of which the total content of schisandrin lignan compounds is 2%-8%, which is the most content component, including schisandrin A, schisandrin B, schisandrin A and hundreds of chemical components . ...
