Objective: To study the chemical composition of round-leaf morning glory. Methods: The compounds were separated and purified by silica gel column chromatography, HPLC and recrystallization. The structure was identified by physicochemical properties and spectral data. Results: Fourteen compounds were isolated from the ethyl acetate and n-butanol extracts of Allium mongolicum and identified as: daucosterol (1), ursovalactone (2), ursolic acid (3) P-Hydroxy phenethyl amine (4), trans-p-hydroxycinnamic acid p-hydroxy phenethylamine (5), cis-ferulic acid acyl p-hydroxy phenethylamine (6), trans ferulic (7), (3R, 5R, 6S, 7E, 9S) -tetramethylcyclohexene monoterpene-5,6-epoxy-7-ene-3,9-diol (8), (6S, 9R) -extrafool (9), (+) - syringaresinol (10), isovitexin (11), syringoride (12), uracil 6S, 9R) -roseoside (14). Conclusion: Compounds 3,8 ~ 12,14 were isolated from this genus for the first time.
