Problems solved by technology

In recent years, many scholars have focused on the determination of the chemical components of purslane, pharmacodynamics and pharmacokinetics, etc. However, there has never been a separation of a new ester compound in purslane and analysis in vitro and in vivo research report
[0004] At present, most of the chemical components isolated from purslane are known, and the structural novelty is low. Therefore, the development and isolation of new compounds in purslane are urgently needed

Abstract

The invention relates to the field of traditional Chinese medicine extraction and separation, in particular to a new compound extracted, separated and identified from a purslane medicinal material aswell as an extraction and separation method and application thereof. The invention provides (7E,9E)-6-oxooctadecyl-7,9-dienoic acid ethyl ester extracted from purslane as well as an extraction and separation method and application thereof. The ester compound is prepared by sequentially adopting alcohol decoction extraction, silica gel column chromatography, polyamide column chromatography, ODS medium-pressure column, Sephadex LH-20 purification, and liquid phase separation. The extraction separation method is simple, convenient, rapid and environment-friendly; the compound separated by the method is relatively high in purity; Pharmacological experiments prove that the obtained compound has anti-tumor and anti-cholinesterase effects, so that the new ester compound extracted from purslane and the salt and derivative thereof can be used as natural products to develop new traditional Chinese medicine, and have broad medical application prospects.

Description

technical field [0001] The present invention relates to the field of extraction and separation of traditional Chinese medicine, in particular to a new compound extracted, separated and identified from purslane medicinal material and its extraction and separation method, specifically an ester compound in purslane and its extraction and separation method and application . Background technique [0002] Purslane (Portulaca oleracea L.), also known as longevity dish, horse amaranth, is a plant of the family Amaranthaceae. Purslane is drought and waterlogging resistant, light and shade resistant, widely distributed, and rich in resources. It has attracted much attention as a wild plant for both medicine and food. The 2015 edition of "Pharmacopia of the People's Republic of China" recorded the dry aerial parts of purslane as medicine. , has the functions of clearing away heat and detoxification, cooling blood to stop bleeding, and stopping dysentery. [0003] Modern pharmacologic...
