Five new oleanane-type glycosides (1-5), along with two known triterpene saponins, were isolated from the roots of Pulsatilla patens var. multifida (Ranunculaceae). The structures of the new triterpene saponins were elucidated as 3-O-β-D-glucopyranosyl(1→2)-β-D-galactopyranosyl hederagenin 28-O-β-D-glucopyran, osyl ester (1), hederagenin 3-O-[β-D- glucopyranosyl(1→2)][β-D-glucopyranosyl(1→6)]-β-D-galactopyranoside (2), 3-O-β-D-glucopyranosyl bayogenin 28-O-α-L-rhamnopyranosyl(1→4)-β-D- glucopyranosyl(1→6)-β-D glucopyranosyl ester (3), 3-O-β-D- glucopyranosyl(1→2)-β-D-galactopyranosyl oleanolic acid 28-O-α-L- rhamnopyranosyl(1→4)-β-D-glucopyranosyl(1→6):β-D-glucopyranosyl ester (4), and 3-O-[β-D-glucopyranosyl(1→2)][β-D-glucopyranosyl(1→6)]-β-D- galactopyranosyl hederagenin 28-O-α-L-rhamnopyranosyl(1→4)-β-n- glucopyranosyl(1→6)'β-D-glucopyranosyl ester (5). Structure elucidation was accomplished by 1D and 2D NMR (HMQC, HMBC, and ROESY) methods, FABMS, and hydrolysis.

Six oleanane saponins were isolated for the first time from leaves of Bellis sylvestris Cyr., the southern daisy. Their structures were established by the extensive use of 2D-NMR experiments, including COSY, TOCSY, NOESY, HSQC, HMBC, CIGAR, H2BC, and HSQC-TOCSY, along with Q-TOF HRMS2 analysis. All of the compounds are constituted by bayogenin as aglycone, and characterized by the presence of an oligosaccharide moiety, consisting of two to four sugar unities esterified at the C-28 carboxyl carbon. One of the isolated compounds is a bisdesmoside containing an additional sugar moiety at the C-3 carbon. The phytotoxic activity assayed against Aegilops geniculata Roth., a coexisting test species, has been evaluated revealing that all the compounds, at the highest concentrations, showed strong phytotoxicity against the leaf development.
Phenolic and triterpenoid glycosides from Aster batangensis

A new phenolic glycoside, asterbatanoside A [p-hydroxyacetophenone-4-O-β-D-xylopyranosyl-(1 → 6)-β-D-glucopyranoside], and two new triterpenoid saponins, asterbatanoside B [2α,3β,23-trihydroxyolean-12-en-28-oic acid-28-O-β-D-glucopyranosyl-(1 → 6)-β-D-glucopyranoside] and asterbatanoside C [3-O-β-D-glucopyranosyl-2β,3β,23-trihydroxyolean-12-en-28- oicacid-28-O-β-D-glucopyranoside] were isolated from the roots of Aster batangensis. Their structures were determined by spectroscopic methods and chemical evidence. The total synthesis of asterbatanoside A is also reported. Copyright
