Publication date: February 2018 Source:Phytochemistry Letters, Volume 23 Author(s): Abdou Tchoukoua, Turibio Kuiate Tabopda, Narandulam Usukhbayar, Ken-ichi Kimura, Eunsang Kwon, Hiroyuki Momma, Takuya Koseki, Yoshihito Shiono, Bonaventure Tchaleu Ngadjui Three previously undescribed oleanane-type saponins acylated with monoterpenic acid, kamerunosides A, B, and C were isolated from the stem liana of Acacia kamerunensis. Their structures were elucidated on the basis of extensive 1D and 2D NMR data and HRESIMS analyses. Their cytotoxicities were evaluated against HL60 cells. Kamerunoside B was the most cytotoxic.
