| Abstract: | In our search for bioactive compounds from the whole plant of Picriafelterrae Lour., three new phenylethanoid glycosides, picfeosides A-C (1-3), along with five known phenylethanoid glycosides,namely wiedemannioside (4), acteoside (5), acteoside isomer (6), cis-acteoside isomer (7), and cis-acteoside (8), were isolated using several chromatographic purification steps, including semipreparation HPLC on RP-18. The structures of the new compounds were elucidated on the basis of extensive spectroscopic analysis. |
