Investigations of the plants from the genus Silene showed that they are sources of ecdysteroids  and that many of them contain significant quantities of biologically active compounds.
We studied lipids occurring in the CHCl3 extract of S. guntensis B. Fedtsch. during extraction from it of ecdysteroids in order to utilize the plant more completely and safely and to establish the effect of the lipid components on the effectiveness of the antibacterial and cytotoxic activity.
Neutral lipids were isolated by separating the extract over a column of silica gel into hydrocarbons (3.34%), esters of fatty acids (FAE) and alcohols (7.83), triacylglycerides (TAG) (2.48), free fatty acids (FFA) (3.12), aliphatic and polyprene alcohols (5.0), and compounds eluted by Et2O (19.58), CHCl3 (3.38), and MeOH (55.26).
It can be seen that FAE, FFA, and TAG made up 13.43% of the total.
