متن کاملA New Triterpenoid Saponin and Two Neolignans from Ligularia veitchiana
Phytochemical investigation of the rhizomes and roots of Ligularia veitchiana afforded a new triterpenoid saponin and two known neolignans named liguveitoside B (1), citrusin A (2) and citrusin B (3), respectively. This is the first demonstration of the occurrence of a 8-O-4’ neolignan and the second report on the isolation of triterpenoid saponin in the genus Ligularia. Their structures were e...
متن کاملBadrakemonin, a New Eremophilane-Type Sesquiterpene from the Roots of Ferula badrakema Kos.-Pol.
Phytochemical investigation of the dichloromethane extract of the dried roots of Ferula badrakema resulted in the identification of one new and six known compounds. Known compounds were sesquiterpene coumarins: mogoltacin, feselol, badrakemin acetate, ferocaulidin, conferone and conferol acetate. The new compound was a sesquiterpene, named badrakemonin. The structures of these compounds were el...

متن کاملPhaeophytin analogues from Ligularia knorringiana.
A new phaeophytin, ligulariaphytin A, together with five known phaeophytins, were isolated from the aerial parts of Ligularia knorringiana. The structure of ligulariaphytin A was elucidated as 13¹-hydroxy-13¹,13²-peroxyphaeophorbide A ethyl ester, and the five known compounds were identified as 13²-hydroxyphaeophorbide A ethyl ester, 17³-ethoxyphaeophorbide A, phaeophytin B, phaeophytin A, and ...
