Problems solved by technology

[0003] At present, there are very few application documents about panarisin at home and abroad, because the content of panarisin in plants is low and extraction is difficult, so the research on panarisine has brought great limitations, so the extraction and preparation of panarisin Li new research has become an urgent problem to be solved
After searching, there is no patent literature report on the new industrial production method of Panari

Abstract

The invention discloses an extracting method of panalicin. The extracting method comprises the steps as follows: carrying out supercritical CO2 extraction to Uvaria narum Wall. to obtain Uvaria narum Wall. extract; then implementing polyamide resin column chromatography; and finally separating and purifying through high-speed counter-current chromatography to obtain the new pure product of panalicin. According to the extracting method of panalicin disclosed by the invention, an extracting technology of panalicin is established at home firstly so as to obtain high-purity panalicin; and moreover, supercritical extraction and high-speed counter-current chromatography are combined; compared with methods such as liquid chromatography, the extracting method disclosed by the invention has the advantages of being environment-friendly, high in preparation amount, safe, stable, and easy for industrialization.

Description

technical field [0001] The invention relates to a method for extracting active ingredients from natural plants, in particular to a new extraction method for panari. Background technique [0002] The molecular formula of Panalicin is C 37 h 66 o 8 , with a molecular weight of 638.93, is a purple jade plate from the Annonaceae plant Na'er Uvaria narum An acetylsarginine compound isolated from the root bark of Wall. Pharmacological studies have shown that Panarisin has antimicrobial activity and anthelmintic activity. [0003] At present, there are very few application documents about panarisin at home and abroad, because the content of panarisin in plants is low and extraction is difficult, so the research on panarisine has brought great limitations, so the extraction and preparation of panarisin Lixin research has become an urgent problem to be solved. After retrieval, there is no patent literature report on the new industrial production method of Panari. Contents of ...
