Preparation method of extractum based on extraction of effective components of herba senecionis scandentis

Abstract

The invention discloses a preparation method of extractum based on extraction of effective components of herba senecionis scandentis. The method includes cleaning, soaking and cutting selected herba senecionis scandentis medicinal materials with intact rhizomes in sequence to obtain the cut herba senecionis scandentis medicinal materials to be boiled; performing two decocting operations on the cutherba senecionis scandentis medicinal materials to be boiled; mixing the first herba senecionis scandentis decoction extract and the second herba senecionis scandentis decoction extract to obtain herba senecionis scandentis medicinal material solution to be concentrated; pumping the solution into a medicinal material concentration kettle; performing two concentration operations successively; collecting and siphoning off steam discharged from the top of the medicinal material concentration kettle to obtain the herba senecionis scandentis medicinal material concentrated solution; filtering thesolution to obtain herba senecionis scandentis medicinal material solution to be evaporated; and finally laying the solution on a tray to preform an evaporation operation to obtain the extractum basedon extraction of the effective components of the herba senecionis scandentis. Therefore, through the preparation method, the extraction rate of the effective components of herba senecionis scandentisis higher, the preparation process of the extractum is simpler, and the product quality of the obtained extractum is more stable.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to a method for preparing an extract based on the extraction of active ingredients from Senecio. Background technique [0002] Qianliguang, also known as Jiuliming, Jiuliguang, Qianliji, has bright eyes, Huanghuacao Huanghuamu, Jiulongguang and Jiulingguang. It is an herbaceous plant of Compositae, which grows in hillsides, under sparse forests, forest edges, roadsides, and ditch grass. Produced in Henan, Shaanxi, Jiangsu, Zhejiang, Guangxi, Sichuan. It is cold in nature, bitter in taste, has the functions of clearing heat and detoxifying, dispelling stagnation and relieving pain. For acute conjunctivitis, acute pharyngitis, acute tonsillitis, acute enteritis, acute bacillary dysentery, upper respiratory tract inflammation, acute bronchitis, lymphadenitis, boil pain, otitis media, dermatitis and eczema. There is a folk saying that "someone knows Senecio, and the whole f...

Problems solved by technology

Although these methods are used by most people in the extraction of natural products, there are still many disadvantages, such as the general use of a large amount of organic solvents in the extraction process; long processing time; many operating steps, etc.

Therefore, the sample loss is serious during the experiment, and the error generated is relatively large.
