Phytochemical investigation of the ethanol extract of the roots of Sanguisorba officinalis resulted in the isolation of three new triterpene glycosides, 3β-[(α-L-arabinopyranosyl)oxy]-19α,23-dihydroxyolean-12-en-28-oic acid 28-[6-O-acetyl-β-D-glucopyranosyl] ester (1), 2α,3β,19α,23-tetrahydroxyurs-12-en-28-oic acid 28-[6-O-acetyl-β-D-glucopyranosyl] ester (2), and 3β-[(α-L-arabinopyranosyl)oxy]-19α-hydroxyurs-12,20(30)-dien-28-oic acid 28-[6-O-acetyl-β-D-glucopyranosyl] ester (3). All the triterpene glycosides exhibited the significant cytotoxic potential with low IC50 values (IC50 5.0 μM) against six tumor cell lines (MCF-7, HeLa, HepG2, SGC-7901, NCI-H460, and BGC-823).

In addition to fourteen known glycosides from leaves of Quercus laurifolia Michx., a new acylated triterpene soponin has been isolated and identified as 3-O-galloyl-28-β-D-glucopyranosyl diester of the 2α,3β,19α,23-tetrahydroxyurs-12-ene-28-oic acid (1). The structure of the previously described α-D-glucopyranosyl ester of the 2α,3β,19α,23-tetrahydroxyurs-12-ene-28-oic acid was revised to β-D-glucopyranosyl ester of the 2α,3β,19α,23-tetrahydroxyurs-12-ene-28-oic acid (2).

No diterpene glycoside was isolated from the roots of Rubus suavissimus S.LEE, in contrast to its leaves, which taste sweet and contain a large amount of the sweet diterpene glucoside named rubusoside.Instead, a new 28-β-glucopyranosyl ester of 2α,3β,19α-trihydroxyurs-12-ene-23,28-dioic acid named suavissimoside F1 was isolated from the roots of this plant, along with niga-ichigoside F1 (28-β- glucopyranosyl ester of 19α-hydroxyasiatic acid) which has already been obtained from leaves of other Rubus spp. Keywords -- Rubus suavissimus root; Rosaceae; 19α-hydroxyursolic acid derivative; triterpene 28-β-glucopyranosyl ester; niga-ichigoside F1; suavissimoside F1
