| Zusammenfassung: | Two new ω-phenylpentaene fatty acid amide diglycosides, rhamnellosides A (
) and B (
), were isolated from the fruits of
(Rhamnaceae). These compounds were prioritized using LC-MS/MS molecular networking dereplication based on our previous discovery of 2-acetoxy-ω-phenylpentaene fatty acid triglycosides berchemiosides A-C from a phylogenetically related species,
. The structures of the isolated compounds were elucidated by spectroscopic analyses in combination with chemical derivatization. The pentaene groups of
and
were found to have (6

, 10
, 12
, 14
)-geometry, which is the same as that found in berchemioside A. |
