Apiaceae family are widely distributed in a Siberian flora and are the
subject of a constant interest within the scientific community as a source of new and
effective bioactive metabolites. As a part of ongoing studies of phenolics produced by
Apiaceous plants [1–3], we discovered some new coumarins and investigated their
biopotential. In particular, four new angular pyranocoumarins phlojosibirinins I–IV
were isolated from the roots of
Phlojodicarpus sibiricus (Fisch.) Koso-Pol. of Baikal
origin and identified as (+)-
cis -khellactone di-
O -esters with fragments of isobutyric,
isovaleric, angelic, and senecic acids. The leaves of the plant were the source of new
non-acylated and acylated (+)-
cis -khellactone
O -glycosides (phlojosibirisides IV–VII)
with moieties of galactose and glucose. Two new umbelliferone and scopoletin
monoacetylated 6′-
O -apioglucosides (villosides I and II) characterized in herb of
Phlojodicarpus villosus (Turcz. ex Fisch. & C.A.Mey.) Turcz. ex Ledeb collected in
Sakha (Yakutia) Republic. Vaginidiol di-esters (ferulopsins A–C) and new vaginidiol-
1′-
O -galactoside were found in roots of
Ferulopsis hystrix (Bunge) Pimenov collected
in Chita region. The plants of
Levisticum officinale W.D.J.Koch cultivated in Siberian
farming demonstrated a high level of apterin [3] and new derivatives including apterin-
O -glycosides in roots and hydroxycinnmate-acylated apterins in herb (levistisides A–
D). Bioactivity studies demonstrated antioxidant, cytotoxic, anticholinesterase-
inhibiting and antibacterial potential of new compounds making wild and cultivated
plants of Siberia promising sources of new pharmacological agents.
