| Overview | the rhizomes, the first in the Ming Dynasty Liu Wentai by the book "The essence of grass". Clinically, it has the effect of dispelling wind and dampness, eliminating swelling and swelling, and is used for the treatment of rheumatism, cold arthralgia, limb clonus, swelling, ulceration and other diseases, it is the main raw material of famous Chinese patent medicine "huoluodan" and "zaizao pill. The chemical constituents of the plant are triterpenoids, organic acids. In recent years, domestic and foreign scholars have isolated a variety of triterpene saponins from the tip of the two heads. Polymorph anemarrhena glycosides 20 is one of them.|
| preparation | The dried two-tip herbs were crushed with 80% ethanol (ethanol/water, the same as below) reflux extraction 2 times, each time 3 hours, combined extract, under reduced pressure to recover solvent ethanol extract 580g. It was suspended in 5L water and extracted with equal amount of petroleum ether, ethyl acetate and n-butanol, respectively. After recovering each part of solvent, the petroleum ether extract, ethyl acetate extract and n-butanol extract were obtained. The n-butanol extract was eluted with water, 10% ethanol, 30% ethanol, 50% ethanol, 70% ethanol and 95% ethanol by AB-8 macroporous resin column, 50% and 70% ethanol eluent, after recovering ethanol under reduced pressure and drying to obtain dry paste, was then subjected to silica gel column chromatography, chloroform-methanol-water (8: 2: 1 volume ratio) elution, thin layer chromatography detection combined into 8 parts, the fourth part of the silica gel column chromatography, chloroform-methanol-water (7: 3: 1 volume ratio) elution, thin layer chromatography detection combined into 4 parts, the second was subjected to Sephadex LH20 column chromatography (60% methanol-water) to give compound 1(24mg), and the third was subjected to Sephadex LH20 column chromatography (60% methanol-water) to give compound 2(12mg). Compound 2 that is more than 20 anemarrhena glycosides. |
| biological activity | raddeoutside 20 is a triterpenoid isolated from the rhizome of Anemone raddeana. Raddeanode 20 can inhibit the production of superoxide. |
