Summary
A new hederagenin-type triterpenoid glycoside (1) named Aytachoside A, along with eight known triterpene glycosides, were isolated from the aerial parts of Cephalaria aytachii Gokturk and Sumbul (Dipsacaceae). The structures of compounds 1-9 were determined by spectroscopic (1D and 2D NMR, HRESIMS) and chemical examinations. The antimicrobial effect of compound 1 was found considerably active against Escherichia coli, Pseudomonas aeruginosa and especially Salmonella typhimurium microorganisms using the MIC method. Although compound 1 was found not to have a remarkable toxic effect at a concentration lower than 300 μg/mL, cytotoxic activity tests demonstrated that prosapogenin 1a exhibits a significant cytotoxic activity against HeLa cell lines using the MTT assay for the first time.
