Problems solved by technology

The most important problem of this technique is to use ethanol as a solvent. Due to the extensive dissolution of ethanol, a large amount of impurities are dissolved into the solution at the same time, so that the scutellarin content in the obtained concentrate (extract) is reduced (generally only at 70%-80%). %), bring very big trouble to the follow-up purification and refining, and the recovery rate is also greatly reduced

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] figure 1 shows the method for extracting scutellarin from scutellaria breviscapus according to the present invention. The method first starts with step S1100, adding scutellaria scutellaria into the treated water heated to boiling, heating to boiling and keeping boiling for a period of time to obtain scutellarin extract. Next, step S1200 is performed, and the breviscapine extract is filtered and put into a sedimentation tank, and the solution is kept heated. Then enter step S1300, add hydrochloric acid to the hot solution in the sedimentation tank, adjust the pH value to 1.5-2.5, and let it stand until the precipitation is complete to obtain the precipitate. Finally, step S1400 is to dry the precipitate to obtain the scutellarin product.

[0017] Optionally, before starting step S1100, the water used for extracting breviscapine needs ...

Abstract

The invention discloses a method for extracting breviscapine by taking Erigeron breviscapus as a raw material. The method comprises the following steps of: adding the Erigeron breviscapus into water which is heated to be boiled and is treated; heating the mixture to be boiled and keeping boiling for a period of time to obtain a breviscapine leaching solution; filtering the breviscapine leaching solution and putting into a sedimentation basin; keeping heating the solution; adding hydrochloric acid into a hot solution of the sedimentation basin and adjusting a pH (Potential of Hydrogen) value to 1.5-2.5; standing to be precipitated completely to obtain sediment; and drying the sediment to obtain a breviscapine product. The method disclosed by the invention is simple and easy to learn and has a high extraction ratio; and the purity of the breviscapine is improved.

Description

field of invention [0001] The invention relates to the field of plant extraction, in particular to an extraction method for obtaining scutellarin from scutellaria scutellaria. Background technique [0002] Erigeron breviscapus (Vant.) Hand-Mazz is the dry whole herb of Compositae. It is also known as Erigeron breviscapus (Vant.) Hand-Mazz. It is mainly distributed in southwest China, especially in Yunnan. It was first recorded in "Southern Yunnan Materia Medica", and was once included in the 1977 edition of "Chinese Pharmacopoeia". Breviscapine is an active ingredient of flavonoids extracted from Breviscapine flower. Its main active ingredient is scutellarin, which accounts for more than 95%, and also contains a small amount of breviscapine. Breviscapine has the effects of increasing blood flow, improving microcirculation, dilating blood vessels, and reducing blood viscosity. It has been widely used clinically to treat cerebral infarction, ischemic heart disease, vertigo, s...
