Phenylethanoid Glycosides from Monochasma savatieri and Their Anticomplement Activity through the Classical Pathway

Five new phenylethanoid glycosides, savasides A–E (1–5), along with 6 known ones were isolated from the whole plant of Monochasma savatieri Franch. The structures of 1–5 were elucidated on the basis of spectroscopic data analysis. Moreover, all isolated compounds were evaluated for anticomplement activity through the classical pathway.
