Embodiment 1
[0020] Example 1. Preparation of Shegan Total Isoflavones
[0021] Shoot dry medicinal material 10Kg, heat extract three times with 10 times the volume of 80% ethanol aqueous solution according to the routine, each extraction time is 100 minutes, filter, combine the filtrate, recover the ethanol under reduced pressure, add water to dilute to 10 times the volume, and add AB- 8 macroporous resin columns, first eluted with water for 5 column bed volumes, then eluted with 90% ethanol aqueous solution for 5 column bed volumes, collected the 90% ethanol eluate, recovered ethanol under reduced pressure, concentrated and dried, and shot to dryness Total isoflavones 198g, total isoflavones were heated and refluxed with 30 times the amount of 80% ethanol to dissolve, filtered, the filtrate was concentrated under reduced pressure to about one-eighth volume, the concentrated solution was left overnight to precipitate, filtered, and dried to obtain total isoflavones product. According to ...
Embodiment 2
[0022] Example 2. Preparation of 12 isoflavone compounds such as iridin, irisin, irisaxanthin, and iridinin (see Jin Li (Jin Li), Chen Hai-sheng (Chen Haisheng), et al.Chemicalconstituents from Belamcanda chinensis Journal of Asian Natural Products Research 2008, 10(1): 89-91)
[0023] 4Kg of dried rhizomes of traditional Chinese medicine were crushed and extracted three times under reflux with 80% ethanol aqueous solution, and the solvent was recovered under reduced pressure to obtain about 200g of liquid extract, which was dispersed in 800ml of distilled water, and then washed with petroleum ether, chloroform and ethyl acetate respectively. Extracted 3 times (500ml each time), and recovered the solvent respectively to obtain 22g of petroleum ether extract, 65g of chloroform extract, and 28g of ethyl acetate extract.
[0024] Get chloroform extract 65g, carry out gradient solvent system for silica gel column chromatography: CHCl 3 →CHCl 3 / CH 3 OH:H 2 O (20:1), fractions ...
Embodiment 3
[0026] Example 3. Test of compound on estrogen-like effect in natural aging rats
[0027] 1. Experimental materials
[0028] (1) Experimental animals
[0029] 100 female SD rats aged 12 to 15 months, all of which were clean animals, were provided by the Animal Experiment Center of the Naval Medical Research Institute, and the Animal Qualification Certificate: SCXK (Army) 2007-011. The pre-experiment animals were acclimatized indoors for one week, the temperature of the feeding environment was 18-22°C, the relative humidity was (50±20)%, and they had free access to drinking water.
[0030] (2) Test drugs
[0031] 1. Shegan total isoflavones and 4 isoflavones: prepared by Example 1
[0032] (1) Shegan total isoflavones (BC), total isoflavones content ≥ 90%.
[0033] (2) Irisin (BC-1)
[0034] (3) Irisin (BC-2)
[0035] (4) Irisxanthin (BC-3)
[0036] (5) Irisin (BC-7
[0037] 2. Positive control drugs:
