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.
