  The MeOH root extracts of four Chironia species, Chironia krebsii, Chironia palustris, Chironia purpurascens, and Chironia baccifera, have been screened for secoiridoids by thermospray lc-ms and lc-uv. Swertiamarine [1], gentiopicroside [3], sweroside [4], eustomoside [5], and eustomorusside [6] were tentatively identified, and the presence of the secoiridoid diglycoside 2 was detected. Compounds 1-4 were subsequently isolated from C. krebsii and C. palustris. The structure of the new secoiridoid 2 (chironioside) was established as swertiamarine-6'-O-(b-D-xylopyranoside) by chemical and spectroscopic methods, including double-quantum-filtered phase-sensitive COSY.

  From the whole plants of Gentiana olivieri, three new bitter secoiridoid glycosides, olivierosides A (1), B (2) and C (3) were isolated together with the known compounds, gentiopicroside, sweroside, 6'-O-β-D-glucosylgentiopicroside, swertiapunimarin, eustomoside, eustomorusside and septemfidoside, and the structures of the new compounds were elucidated based on spectroscopic and chemical evidence.
