Phaeophytin 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 ...

متن کاملPhytotoxic Eremophilanes from Ligularia macrophylla.
Systematic bioassay-guided fractionation of the methylene chloride extract of the roots from Ligularia macrophylla was performed to identify both phytotoxic and antifungal compounds. Four phytotoxic eremophilanes (furanoeremophilan-14beta,6alpha-olide, 6beta-angeloyloxy-10beta-hydroxyfuranoeremophilane, eremophil-7(11)-ene-12,8alpha;14beta,6alpha-diolide, and 3alpha-angeloyloxybakkenolide A) an...
متن کاملPhytotoxic Terpenoids from Ligularia cymbulifera Roots
Ligularia cymbulifera is one of the predominant species in the Hengduan Mountains, China, and has led to a decrease in the amount of forage grass in this area. However, little is known about the mechanism behind its predominance. In this study, two novel eremophilane sesquiterpenes, ligulacymirin A and B (1 and 2), together with seven other known terpenoids (3-9), were isolated from the roots o...
