| 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‐ (1H, 13C) and 2D‐NMR (DQF‐COSY, TOCSY, HSQC, and HMBC) experiments, HR‐ESI‐MS, and acid hydrolysis. |
