Abstract

The invention relates to a method for preparing a natural pyrrole derivative, namely 4-(formyl-5-hydroxymethyl-1H-pyrrol-1-yl) butanoic acid, from a plant brassica rapa L. by extraction, purification and separation, belonging to the field of natural product extraction. Currently, all domestic and overseas methods for naturally extracting 4-(formyl-5-hydroxymethyl-1H-pyrrol-1-yl) butanoic acid have the defects of low yield, triviality and complexity, high cost and the like. The invention provides a method for obtaining 4-(formyl-5-hydroxymethyl-1H-pyrrol-1-yl) butanoic acid with the purity of greater than 98% from the plant brassica rapa L. by extraction, purification and separation. The method for preparing the natural pyrrole derivative from the plant brassica rapa L. by extraction, purification and separation is significant to the deep processing and the added value promotion of the brassica rapa L; and the extraction method is simple to operate, the yield and the purity of products are high, and the cost is low.

Description

technical field

[0001] The present invention relates to from plant turnip ( Brassica rapa L.) A method for preparing a natural pyrrole derivative, namely 4-(formyl-5-hydroxymethyl-1hydro-pyrrol-1-yl)butanoic acid, by extraction, separation and purification, belongs to the field of natural product extraction. Background technique

[0002] Turnip ( Brassica rapa L.) is a plant of the genus Brassica in the family Brassicaceae ("Flora of China", volume 33). Turnip has a long history of use in traditional medicine and ethnic medicine in my country. The ancient name of turnip is fen, which was first recorded in "The Book of Songs", and its medicinal use was first recorded in "Famous Doctors". At present, turnip is widely cultivated in our country. It is mainly called "manjing" in the north, "pancai" in the southeast coastal area, "round root" in the Qinghai-Tibet plateau, and "Qamagu" in Xinjiang. , In Liangshan Prefecture, Sichuan alone, there is an annual output of more th...
