Objective To study the chemical constituents from the roots of Gypsophila pacifica. Methods The chemical constituents were isolated by various column chromatographic methods and their structures were identified by spectral data together with physicochemical analysis. Results Five compounds were isolated and identified as 3-O-β-D-galactopyranosyl-(1→2)-[β-D-xylopyranosyl-(1→3)]-β-D-glucuronopyranosyl gypsogenin 28-O-β-D-xylopyranosyl-(1→4)-α-L-rhamnopyranosyl-(1→2)-β-D-fucopyranoside (1), 3-O-β-D-galactopyranosyl-(1→2)-[β-D-xylopyranosyl-(1→3)]-β-D-glucuronopyranosyl quillaic acid 28-O-β-D-xylopyranosyl-(1→4)-α-L-rhamnopyranosyl-(1→2)-β-D-fucopyranoside (2), 3-O-β-D-galactopyranosyl-( 1→ 2 )-[β-D-xylopyranosyl-( 1→ 3 ) ]-β- D-glucuronopyranosyl gypsogenin 28-O-β-D-glucopyranosyl-( 1→ 3 )-[β-D-xylopyranosyl-( 1→4 ) ]-α-L-rhamnop yranosyl-( 1 → 2 )-β-D-fucopyranoside (3),3-O-β-D-galactopyranosyl-(1→2)-[β-D-xylopyranosyl-(1→3)]-β-D-glucuronopyranosyl quillaic acid 28-O-β-D-glucopyranosyl-( 1→ 3 )-[β-D-xylopyranosyl-( 1→4 ) ]-α-L-rhamnopyranosyl-( 1→2 )-β-D-fucopyranoside ( 4), 3-O-β-D-galactopyranosyl-(1→2)-[β-D-xylopyranosyl-(1→3)]-β-D-glucuronopyranosyl quillaic acid 28-O-α-L-arabinopyranosyl-(1→4)-α-L-arabinopyranosyl-(1→3)-β-D-xylopyranosyl-(1→4)-α-L-rhamnopyranosyl-(1→2)-β-D-fucopyranoside (5). Conclusion The five compounds are isolated from this plant for the first time.
