Abstract
- Four new glycosylated compounds have been isolated from the whole plant of Tephroseris kirilowii, including ( - )-(1R,5R,6S,7R,8S)-8-O-β-d-glucopyranosyloxy-7-hydroxy-6-(2-hydroxypropan-2-yl)-9-methylenebicyclo[4.3.0]non-3-one (tephroside A, 1), ( - )-(1R,5R,6R,8R)-6-(2-O-β-d-glucopyranosyloxypropan-2-yl)-8-hydroxy-9-methylenebicyclo[4.3.0]non-3-one (tephroside B, 2), thesinine-4'-O-α-l-rhamnoside (3), and p-coumaric acid 4-O-α-l-rhamnoside (4), together with the known roseoside. The structures of the new compounds were established by means of spectroscopic analysis. [ABSTRACT FROM AUTHOR]
