Three new sesquiterpenoids, salplebeones A - C (1 - 3), were isolated from the ethanol-soluble extract of the aerial part of Salvia plebeia R. Br. Their structures were established by detailed analysis of NMR and MS spectra. Salplebeone A was an eudesmane lactone, while salplebeones B and C were
Seven eudesmane-type sesquiterpenoid lactones and the known plebeiolide C were isolated from an ethanol-soluble extract of the aerial parts of Salvia plebeia R. Br. Their structures were determined via NMR and MS, and their absolute configurations were elucidated using ECD, and X-ray
Four new eudesmane-type sesquiterpenes, named plebeiolide A-C (1-3) and plebeiafuran (4), together with a known eudesmanolide (5), were isolated from the basal leaves of Salvia plebeia R. Br. Their structures were elucidated by extensive spectroscopic analysis including 1D and 2D NMR, HR-ESI-MS
Nine new sesquiterpenoid lactones and 11 known analogues were isolated from the aerial parts of Salvia plebeia R.Br. Their structures were elucidated via HRESIMS and NMR data, and their absolute configurations were defined via electronic circular dichroism data, X-ray crystallographic analysis, and
BACKGROUND
Salvia plebeia R. Brown, a traditional Chinese medicinal herb, has been used to treat inflammatory diseases such as cough, hepatitis, and diarrhea for a long history.
OBJECTIVE
The aim of the present study was to isolate and identify potential anti-inflammatory agents from the herb of S.
