TRITERPENOID SAPONINS FROM CENTIPEDA MINIMA

Article abstract of DOI:10.1016/0031-9422(89)80208-0

Four new triterpenoid saponins were isolated from the whole plant of Centipeda minima.They were characterized as 1α,3β,19α,23-tetrahydroxyurs-12-en-28-oic acid-28-O-β-D-xylopyranoside, 1β,2α,3β-19α-23-pentahydroxyurs-12-en-28-oic acid-28-O-β-D-xylopyranoside, 3α,21α,22α,28-tetrahydroxyolean-12-en-28-O-β-D-xylopyranoside and 3α,16α,21α,22α-28-pentahydroxyolean-12-en-28-O-β-D-xylopyranoside.Structrures of all compounds were elucidated by spectroscopic methods with emphasis on mass spectra, 1H and 13C NMR spectra.Key Word Index - Centipeda minima; Compositae; triterpenoid saponins; ursane and oleanane derivatives.
