We have investigated the glycoside composition of the roots of K~utia ~ver~i8 (L.) Coult, family Dipsacaceae, collected in the Tatar Autonomous Soviet Socialist Republic. In an aqueous methanolic extract of the plant we found a number of glycosides, theree of which we succeeded in isolating by repeated chromatography in a column of silica gel in the ethyl acetate-~ethanol-water system. One of them is a monoglucoside of B-sitosterol (0.1% on the weight of the raw material) with mp 285-286°C, [a] D-39 ° (pyridine)-identified by comparison with an authentic sample. The other two have been isolated for the first time and we have called them knautiosides A and B (0.5% on the weight of the raw material); they have mp 208-213,C, [aiD-10°C (pyridine) and mp 240-244°C [aiD-13 ° (pyridine), respectively. On treatment with mineral acid they formed the same aglycone CsoH4803 with mp 255-256°C, [a]D + 188 = (pyridine). According to its chromatograph mobility (thin-layer chromatography) and IR spectrum and also from the constants of various derivatives (acetate, methyl ester, acetate of the methyl ester), this aglycone best corresponds with a triperpenoid described previously-randialic acid B [i].
