  abstract = {{I}n our continuing search of saponins from the plant of {S}apindaceae family, phytochemical investigation of the stem barks of {P}ancovia turbinata {R}adlk., led to the isolation and structural characterization of two new triterpenoid saponins, named turbinatosides {A}-{B} (1-2), one new farnesyl glycoside, named turbinoside {A} (3), one new coumarin glucoside, named panturboside {A} (4), together with a known saponin (5). {T}he structures of the new compounds were established, using extensive analysis of {NMR} techniques, mainly 1{D} {NMR} ({H}-1, {C}-13, and {DEPT}) and 2{D} {NMR} ({COSY}, {NOESY}, {HSQC}, {HSQC}-{TOCSY} and {HMBC}) experiments, {HRESIMS} and by comparison with the literature data, as 3-{O}-beta-{D}-xylopyranosyl-(1 -> 3)-alpha-{L}-arabinopyranosyl-(1 -> 4)-beta-{D}-glucopyranosyl-(1 -> 3)-alpha-{L}-rhamnopyranosyl-(1 -> 2)-alpha-{L}-arabinopyranosylhederagenin 28-{O}-beta-{D}-glucopyranosyl ester (1), 3-{O}-alpha-{L}- arabinopyranosyl-(1 -> 4)-beta-{D}-glucopyranosyl-(1 -> 3)-alpha-{L}-rhamnopyranosyl-(1 -> 2)-alpha-{L}-arabinopyr-anosylhederagenin 28-{O}-beta-{D}-xylopyranosyl-(1 -> 4)-beta-{D}-glucopyranosyl ester (2), 1-{O}-{beta-{D}-glucopyranosyl-(1 -> 3)-alpha-{L}-rhamnopyranosyl-(1 -> 2)-[alpha-{L}-rhamnopyranosyl-(1 -> 6)]-beta-{D}-glucopyranosyl}-(2{E},6{E})-farnes-1,12-diol (3), and 5-{O}-beta-{D}-glucopyranosyl-5,6,7-trihydroxy-8-methoxycoumarin (4), respectively. {O}ur findings highlight the presence of -(3){R}ha-(2){A}ra-(3)hederagenin oligosaccharidic sequence usually described in saponins from {S}apindoideae subfamily of {S}apindaceae family, as well as farnesol glycosides, and represent therefore a valuable contribution to the chemotaxonomy of the {S}apindoideae subfamily.},
