Currently, herbal medicines are widely used in medicine for the treatment and the 
prevention of various diseases. For this reason, we studied the chemical composition of 
the plant 
Astragalus transoxanus
Fisch., which belongs to 
Fabaceae
family. 
The previously known individual triterpenoids lupeol (
1
), cyclodisectoside (
2
), and 
cyclosiversioside E (
3
) were isolated from the chloroform and 
n
-butanol fractions of the 
aerial part of this plant. 
The structure of the compounds was established on the basis of 
1
H and 
13
C NMR 
spectra. Also TLC was used for identification of mentioned above compounds. 
Thus, the plant 
Astragalus transoxanus
was found to contain previously known 
triterpenoids, which were found in this plant for the first time.
