Abstract: By investigating the Chemical constituents of the roots of Launaea sarmentosa, collected at Can Gio beach, Can Gio district, Ho Chi Minh city, nine compounds were isolated including α-amyrin acetate (1), β-amyrin acetate (2), lupeol acetate (3), Ψ-taraksasterol acctatc (4), luteolin (5), 4-allyl-2,6-dimethoxyphenol glucopyranoside (6), scorzoside (7), ixerisoside D (8) and 9 α-hydroxypinoresinol (9). To the best of our knowledge, all compounds were reported in other species, but this is the first time they were known in L. sannentosa. Four compounds (1-4) from the n-hexane extract were identified by 4-dimethylaminopyridine-catalyzed benxoylation. Their chemical structures were elucidated by means of 1D and 2D NMR, HR-ESI-MS data analysis and compared with those reported in the literature.
