Abstract
The waste products of the production of ecdysterone (3) from Silene praemixta M. Pop. (Caryophyllaceae) were investigated. The column chromatography of the technological waste has allowed to isolating 2-de- soxyecdysone (1), 2-deoxyecdysterone (2), ecdysterone (3) and 22-O-β-D-glucopyranoside of 2-deoxyecdy- sone (4). Glucoside 4 was found for the first time in the plant Silene praemixta. Ecdysteroids 1, 2 prevailed in the sum. Compounds 3 and 4 were minor components of the waste products. The identification of com- pounds 1-4 was carried out by using the modern me- thods of 1D and 2D NMR spectroscopy: 1H, 13C, DEPT, 1H-1H COSY, HSQC, NOESY, IR spectroscopy and ESI MS.
