Abstract:
Five new triterpenoid saponins, including 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 ‐xylopyranosyl‐(1→3)‐(4‐ O ‐acetyl)‐ β ‐ d ‐quinovopyranosyl‐(1→4)]‐ β ‐ d ‐fucopyranoside ( 1 ), 3‐ O ‐ β ‐ d ‐galactopyranosyl‐(1→2)‐[ β ‐ d ‐xylopyranosyl‐(1→3)]‐ β ‐ d ‐glucuronopyranosyl quillaic acid 28‐ O ‐(6‐ O ‐acetyl)‐ β ‐ d ‐glucopyranosyl‐(1→3)‐[ β ‐ d ‐xylopyranosyl‐(1→4)]‐ α ‐ l ‐rhamnopyranosyl‐(1→2)‐[ β ‐ d ‐xylopyranosyl‐(1→3)‐(4‐ O ‐acetyl)‐ β ‐ d ‐quinovopyranosyl‐(1→4)]‐ β ‐ d ‐fucopyranoside ( 2 ), 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 ‐xylopyranosyl‐(1→3)‐(4‐ O ‐acetyl)‐ β ‐ d ‐quinovopyranosyl‐(1→4)]‐ 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)‐[(4‐ O ‐acetyl)‐ β ‐ d ‐quinovopyranosyl‐(1→4)]‐ β ‐ d ‐fucopyranoside ( 4 ), 3‐ O ‐ β ‐ d ‐galactopyranosyl‐(1→2)‐[ β ‐ d ‐xylopyranosyl‐(1→3)]‐ β ‐ d ‐glucuronopyranosyl quillaic acid 28‐ O ‐(6‐ O ‐acetyl)‐ β ‐ d ‐glucopyranosyl‐(1→3)‐[ β ‐ d ‐xylopyranosyl‐(1→4)]‐ α ‐ l ‐rhamnopyranosyl‐(1→2)‐[(4‐ O ‐acetyl)‐ β ‐ d ‐quinovopyranosyl‐(1→4)]‐ β ‐ d ‐fucopyranoside ( 5 ) together with two known congeners, saponariosides A ( 6 ) and B ( 7 ) were isolated from the roots of Saponaria officinalis L. Their structures were elucidated by extensive spectroscopic methods, including 1D‐ ( 1 H, 13 C) and 2D‐ NMR ( DQF ‐ COSY , TOCSY , HSQC , and HMBC ) experiments, HR ‐ ESI ‐ MS , and acid hydrolysis.
