Phlinoside F,a new phenylethanoid glycoside from Phlomis angustissima

From the overground parts of Phlomis angustissima, a new phenylethanoid triglycoside, $\beta$-(3-hydroxy,4-methoxyphenyl)ethyl- O-[$\beta$ -xylopyranosyl($1\rightarrow 2$)-a -rhamnopyranosyl-($1\rightarrow 3$)] -O-4-O-feruloyl- $\beta$ -glucopyranoside, named phlinoside F, was isolated along with the known compounds alyssonoside, samioside, lamiide, auroside, naringenin, and syringaresinol-4-O-$\beta$ -D-glucopyranoside. The structure of the new glycoside was elucidated by spectroscopic methods.
