Triterpene glycosides ofHedera taurica XVI. Structures of glycosides St-A, St-B1, St-B2, St-C, St-D1, St-D2, St-E, St-F1, and St-F2 from the stems of Crimean ivy

From the stems of Crimean ivyHedera taurica Carr. (fam. Araliaceae) we have isolated previously known glycosides of oleanolic acid — the 3-O-O--L-rhamnopyranosyl-(12)--L-arabinopyranoside], the 3-O--D-glucopyranuronoside, and the 3-O-O--D-galactopyranosyl-(12)--D-glucopyranuronoside]; known glycosides of hederagenin — the 3-O--L-arabinopyranoside, the 3--D-glucopyranoside, the 3-O-O--D-glucopyranosyl-(12)-O--L-arabinopyranoside], and the 3-O--D-glucopyranuronoside; and also the new triterpene glycoside St-D₂, hederagenin 3-O-O--L-rhamnopyranosyl-(12)--D-glucopyranoside].Simferopol' State University.
