Abstract

The invention relates to the field of extraction and separation of traditional Chinese medicine, in particular to a new compound extracted, separated and identified from a Portulaca oleracea L. medicinal material as well as an extraction and separation method and an application of the new compound, and specifically provides a compound Oleraciamide E in Portulaca oleracea L. as well as the extraction and separation method and the application of the compound Oleraciamide E. The extraction and separation method of the new compound comprises steps as follows: water decoction extraction, ethyl acetate extraction, macroporous resin column chromatography, silica-gel column chromatography, ODS (Octadecylsilyl) medium-pressure column and Sephadex LH-20 purification and liquid-phase separation are adopted sequentially for preparation, and the compound is structurally determined to be a new alkaloid compound with UV, IR, HR-ESI-TOF-MS, <1>H-NMR, <13>C-NMR and two-dimensional magnetic resonance ectroscopy analysis methods. The compound has potential anti-inflammation and anti-tumor effects and other activity, and the new compound and salts or derivatives of the new compound can be taken as a raw material for primer synthesis from other compounds, new drug development and pharmacological activity research, and the primer and theoretical basis are provided for development of new drugs and new components.

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 a compound Oleraciamide E in purslane and its extraction and separation method and application . Background technique [0002] purslane( Portulaca oleracea L.), also known as long-lived vegetable and horse amaranth, is a plant of the family Portulaca oleracea. 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.
