Triterpenoid saponins from the roots of Gypsophila trichotoma Wender.

Selective Profiling of Saponins from Gypsophila trichotoma Wend. by HILIC Separation and HRMS Detection

“…, Table ), previously isolated from G. trichotoma, were used as reference standards. Their structures were assigned by NMR and ESI‐HRMS (Voutquenne‐Nazabadioko et al ., ).…”

“…Note: Mass spectra of A – G were acquired at HCD 30. Fragmentation data of H/I and J/K were previously reported (Voutquenne‐Nazabadioko et al ., ).…”

“…var. trichotoma originated from Bulgaria (Voutquenne‐Nazabadioko et al ., ). They have gypsogenin as their common aglycone substituted at C‐3 with a branched trisaccharide chain ending with variable pentose unit (xylose/arabinose) and at C‐28 with an ester‐bonded tetrasaccharide or pentasaccharide possessing methoxycinnamoyl, acetyl and (or) sulphate groups.…”

Two new oleanane-type triterpene saponins from the leaves of Schefflera sessiliflora De P. V.

“…CH 3 COOH (5 ml) for 2 h at 100 8C. After extraction with CH 3 Cl (3Â 5 ml), the aqueous layer was repeatedly evaporated to dryness with MeOH until neutral, and then analyzed by TLC over silica gel (MeCOEt-isoPrOHMe 2 CO-H 2 O 20:10:7:6) by comparison with authentic samples (Lrhamnose Rf 0.65; D-glucose Rf 0.40; D-glucuronic acid Rf 0.05) (Haddad et al, 2013;Voutquenne-Nazabadioko et al, 2013).…”
