Silene genus (Caryophyllaceae) is represented by 119 species, wild and cultivated, in Middle and East Anatolia, Azerbaijan, Iran and
Iraq. Due to its wide range of biological and pharmacological effects, Silene species are used as herbal medicine. S. gonosperma,
S. morcrooftiana W., S. edgeworthii, S. chlorifolia, S. acaulis, S. floscuculi L. and S. vulgaris have been used in the treatment of eye
and skin problems, dysentery, inflammation, colic, malaria and stomach pains, urinary infection, respectively. S. vulgaris has been
used for its sedative effect and as an anti-toxic agent. Modern biological studies have shown that Silene species exhibit a wide range
of biological actions. It has been reported that S. armeria L. showed moderate antifungal activity against all plant pathogens. S.
swertiifolia and S. spergulifolia had a high antibacterial activity against gram negative and positive bacteria. S. montbretiana was
collected from Malatya, Turkey in 2010. Air-dried and powdered whole plant material was extracted with MeOH. After filtration, the
residue was dissolved in water and then partitioned n-BuOH saturated with H2O. The n-BuOH phase was fractioned over RP-VLC
to give eight main fractions. Fractions were subjected to open column chromatography by using normal and reverse phase silica gel
as adsorbents. This is the first study that describes the isolation and identification of secondary metabolites from S. montbretiana.
In this study, two new steroids (SM 4, SM 16) 2���²,3���²,14���±,20S,25- pentahydroxy-cholest-7-en-6-one, 3-O-���²-D-glucopyranosyl,25-
O-���²-D-glucopyranosyl-3���²,25- dihydroxycholest-7-en-6-one, along with eight known compounds (six steroids, one flavonoid, and
one cerebroside) were isolated from the methanolic extract. Their structures were elucidated by extensive spectroscopic methods
including 1D- and 2D-NMR techniques as well as ESIMS and HRMS analyses.
