preparation example Construction

[0056] The extraction step of ephedra performed in the production method of the present invention can be performed based on any of the well-known methods. As the extraction solvent, other organic solvents such as water, warm water, hot water, alcoholic solvents, and acetone can be used. Examples of alcohol-based solvents include methanol, ethanol, propanol, isopropanol, butanol, isobutanol, and the like. These solvents may be used alone or in combination.

[0057] The amount of the extraction solvent is preferably 2-100 parts by weight relative to the dry weight of ephedra. The extraction temperature is preferably 4-98°C. The extraction time is preferably 30 minutes to 2 hours. The extraction method can be performed by any method such as stirring extraction, immersion extraction, convection extraction, ultrasonic extraction, supercritical extraction and the like.

[0058] The obtained extract, the filtrate obtained by filtering the extract, the concentrate obtained by conc...

Embodiment 1

[0094] Embodiment 1: the making of ephedra extract.

[0095] The dry raw material of ephedra was pulverized by a mixer, and 500 mL of water was added to 50 g of the pulverized product, and extracted at 95° C. for 1 hour while stirring. Solid-liquid separation was performed, and the extract was centrifuged at 3000 rpm for 10 minutes. The obtained supernatant was concentrated under reduced pressure at 60° C., and then dried under reduced pressure at 60° C. overnight to obtain 9.6 g of ephedra extract.

Embodiment 2

[0096] Example 2: Production of ephedra alkaloid-removing ephedra extract by ion exchange resin SK1B.

[0097] The dry raw material of ephedra was pulverized by a mixer, and 500 mL of water was added to 50 g of the pulverized product, and extracted at 95° C. for 1 hour while stirring. Solid-liquid separation was performed, and the extract was centrifuged at 3000 rpm for 10 minutes, and the obtained supernatant was passed through 25 mL of strong-acid cation exchange resin SK1B (manufactured by Mitsubishi Chemical). Dilute the passage solution with 5% NaHCO 3 Adjusted to pH = 5.2, concentrated under reduced pressure at 60° C., and dried under reduced pressure at 60° C. overnight to obtain 6.3 g of an alkaloid-removing ephedra extract of the genus Ephedra.

Abstract

Provided is an ephedra extract stripped of ephedrine alkaloids, i.e., an ephedra extract from which ephedrine alkaloids have been removed, and a method for producing an ephedra extract stripped of ephedrine alkaloids. Also provided are an antineoplastic / antimetastatic agent, a pain inhibitor, and an anti-influenza virus drug that include said ephedra extract as an active ingredient.

Description

technical field [0001] The present invention relates to a more safe alkaloid-removing ephedra extract of the genus Ephedra, a method for preparing it, and an anticancer, anti-metastasis drug, pain suppressant drug, and anti-influenza virus drug using it as an active ingredient. Background technique [0002] Ephedra is the aerial stem of Ephedrasinica Stapf, Ephedra intermedia Schrenket C.A. Meyer or Ephedra equisetina Bunge (Ephedraceae) plants of the Ephedra family. Ephedra is the most important crude drug used since ancient times. Examples of traditional Chinese medicines (traditional Chinese medicine prescriptions) containing ephedra as a constituent crude drug include: Aconitum decoction, Wuyao Shunqi decoction, Yuebi decoction, Yuebijiashu decoction, Huishou decoction Powder, Huagai Powder, Gegen Decoction, Gegen Decoction plus Chuanxiong Magnolia, Gegen plus Shufu Decoction, Gegen plus Pinellia Decoction, Gancao Mahuang Decoction, Guijiang Zaocao Huangxinfu Decoction, ...
