From the branches of Pittosporum senacia Putterlick (Pittosporaceae), two new triterpenoid saponins, senaciapittosides A and B (1, 2), were isolated. Their structures were elucidated by extensive analysis of one- and two-dimensional nuclear magnetic resonance spectroscopy, high-resolution electrospray ionization mass spectrometry (HR-ESIMS) and chemical evidence as 3-O-[β- d-glucopyranosyl-(1 → 2)]-[α- l-arabinopyranosyl-(1 → 3)]-[α- l-arabinofuranosyl-(1 → 4)]-β- d-glucuronopyranosyl oleanolic acid 28-O-β- d-glucopyranosyl ester (1) and 3-O-[β- d-glucopyranosyl-(1 → 2)]-[α- l-arabinopyranosyl-(1 → 3)]-[α- l-arabinofuranosyl-(1 → 4)]-β- d-glucuronopyranosyl-22-O-α- l-arabinopyranosyl-21-acetoxy R1-barrigenol (2). Compound 2 presents an unusual glycosylation at C-22 of its aglycone. Copyright © 2012 John Wiley & Sons, Ltd.
