Abstract

The invention relates to the field of extraction and separation of traditional Chinese medicines, in particular to a new compound extracted, separated and identified from a portulaca oleracea medicinal material, an extraction and separation method and application thereof, and particularly relates to an extraction and separation method and application of a furan ring compound in portulaca oleracea.The extraction and separation method of the new compound sequentially adopts ethanol extraction, silica gel column chromatography, polyamide column chromatography, macroporous resin column chromatography, ODS medium-pressure column and Sephadex LH-20 purification, and liquid phase separation for preparation. The structure of the compound is determined as a new furan ring compound by adopting UHPLC-ESI-TOF-MS, <1>H-NMR, <13>C-NMR and two-dimensional nuclear magnetic spectrum analysis method. The compound has potential anti-inflammatory and neuroprotective effects and other activities, the newcompound and salts or derivatives thereof can be used as other compound synthesis primers and raw materials for new drug development and pharmacological activity research, and the primer and theoretical basis are provided for new drug development and new component development.

Description

technical field [0001] The invention relates to the field of extraction and separation of traditional Chinese medicines, in particular to a new compound extracted, separated and identified from purslane medicinal material and its extraction and separation method, specifically a method for extraction and separation of a furan ring compound in purslane and its 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 pharmacolog...
