Liquid-liquid separation chromatography device

Abstract

The invention discloses a liquid-liquid separation chromatography device which comprises an upper liquid container 1 and a lower liquid container 14, wherein the upper liquid container 1 is connected with the lower liquid container 14 by a visual clock 9; the upper liquid container 1 and the lower liquid container 14 are fixed by a container connecting column 11; an upper oblique paddle 5 and a lower oblique paddle 12 are arranged in the upper liquid container 1 and the lower liquid container 14, and are fixed on a vibration shaft 3; the visual clock 9 is conventional; an upper liquid valve 10 is arranged at the middle section of the visual clock 9; and the upper liquid valve 10 and the top of the lower liquid container 14 are fixed by a connecting rod. According to the device, the visual clock of the upper liquid valve is arranged between the two liquid containers, the interface of a connecting end between the upper liquid container and the lower liquid container is small, and a lower liquid valve is arranged at the bottom of the lower liquid container, so that the respective recovery of upper and lower liquid phases can be controlled easily. The device is simple in structure, easy to process and operate, small in floor area, relatively good in practicability, economic benefits and social benefits, good in liquid-liquid separation effect, economic and reasonable.

Description

technical field [0001] The invention relates to a liquid-liquid separation chromatography device, which belongs to the technical field of traditional Chinese medicine. Background technique [0002] Jasminum samba (Jasminum samba) is an angiosperm, Oleaceae, Jasminum (or Jasmine) plant, native to India, and now it is widely cultivated in Guangxi, Guangdong, Jiangsu, Sichuan, Fujian, Yunnan and other places in my country, and has become the world's largest jasmine flower. The country with the largest production. The national jasmine cultivation area has reached 3333hm 2 , accounting for about 2 / 3 of the world's cultivated area, and its annual output accounts for more than 50% of the world's total jasmine output. Jasmine has a very long flowering period, from early summer (May) to late autumn (October), the flowers bloom in an endless stream, and its roots, stems, leaves, and flowers are all treasures and have medicinal value. According to "Compendium of Materia Medica", jasm...
