Embodiment 1

[0034] Example 1: Compound extraction and separation and structural identification

[0035] The extraction method of the extract of Cimicifuga cyclopine-type triterpenoids produced in China: the dried rhizomes and Fibrous roots, crushed, heated to reflux with 50-70% ethanol or propanol, extracted 1-4 times. Combine the extracts and concentrate under reduced pressure to remove the solvent in the extracts to obtain ethanol or propanol extract. Dissolve the extract in distilled water or a small amount of 50% ethanol, suspend it in distilled water, add petroleum ether solvent for 1-4 times of extraction, and similarly distill the suspension of the extract in distilled water extracted by petroleum ether with acetic acid Ethyl esters and other esters are extracted for 1-4 times to obtain ester extracts. Concentrate under reduced pressure to remove the solvent in these extracts to obtain ester extracts. Ester extract is dissolved in 95-100% ethanol, by gac column chromatography, r...

Embodiment 2

[0067] Example 2: Anti-resorptive activity

[0068] The compounds in Figures 1 and 2 were prepared in the three concentrations described in the table below with Ham's F-12 culture medium. Use suckling mice 2 days after birth, and inject subcutaneously 45 CaCl 2 (2 Ci), after 2 days, remove the skull, use Ham's F-12 culture medium, at a temperature of 37 ° C, CO 2After pre-cultivation for 24 hours under the condition of 5%, replace the new culture medium, and add 1,25 dihydroxy active vitamin D3 (1,25-(OH) 2 VD 3 , final concentration 10 -10 M) and each compound (see the table below for the final concentration, 200; 20 and 2 micromolar) continued to culture for 3 days under the same conditions as the pre-cultivation, and measured the amount of 45 Ca (measured value 1). Renew this culture medium, continue to cultivate under the same conditions as pre-cultivation again for 3 days, and measure the amount released into the culture medium in the same way. 45 Ca (measured valu...

Abstract

The invention discloses the application of cimig-jackfruit triterpane compound in preventing osteoporosis and climacteric metancholia. The method for preparing said triterpenes compound comprises: collecting dry root of C. dahurica, C. heracleifolia and C. foetida, disintegrating, heating with 50-70% ethanol or propanol, refluxing, extracting for 1-4 times; merging extract, compression condensing to remove dissolvent from extract and getting ethanol or propanol concrete; extracting with benzinum purificatum and acetic acid ethyl ester for 1-4 times, getting ester extract; activated char column chromatography, washing with 95-100% ethanol, separating with positive phase and reverse phase silica gel column, purifying and getting following 24 kinds of triterpenes compound, the compound is cycloartanes.

Description

1. Technical field [0001] The invention relates to triterpenoids (including triterpene glycosides) obtained from three commonly used traditional Chinese medicines, Cimicifuga foetida L., Cimicifuga heracleifolia Komarov and Cimicifuga dahurica (Turcz) Maxim The compound is used as an anti-osteoporosis, climacteric syndrome drug and a health care product. 2. Background technology [0002] Osteoporosis is known as a silent epidemic. It is a common and complex disease in middle-aged and elderly people characterized by decreased bone tissue mass and microstructural degeneration, resulting in increased bone fragility and susceptibility to fracture. According to the statistics of the World Health Organization, there are currently more than 200 million people with osteoporosis. There are 10 million patients in the United States with an estimated direct medical cost of $14 billion. It is estimated that Japan has now reached 10 million, and there is a tendenc...
