Embodiment 1
[0019] Example 1. Preparation of irisin, irisaxanthin, subirisanthin, irisin, iridin (see Jin Li (Jin Li), Chen Hai-sheng (Chen Haisheng), et al.Chemical constituents from Belamcanda chinensis Journal of Asian Natural Products Research 2008, 10(1): 89-91)
[0020] 4Kg of dried rhizomes of traditional Chinese medicine were crushed and extracted three times under reflux with 80% ethanol, and the solvent was recovered under reduced pressure to obtain about 200g of liquid extract, which was dispersed in 800ml of distilled water and extracted with petroleum ether, chloroform and ethyl acetate in sequence 3 times (500ml each time), after recovering the solvent respectively, 22g of petroleum ether extract, 65g of chloroform extract, and 28g of ethyl acetate extract were obtained.
[0021] Get chloroform extract 65g and carry out silica gel column chromatography, use gradient solvent system CHCl 3 →CHCl 3 / CH 3 OH:H 2 O (20:1) eluted to give fractions C1, C2 and C3, respectively. ...
