Cycloartane triterpenoids from Cassia occidentalis.

Abstract:

:A phytochemical investigation of the whole plants of Cassia occidentalis led to the isolation of two new cycloartane triterpenoids, cycloccidentalic acids A and B (1 and 2), and five new related saponins, cycloccidentalisides I-V (3-7), together with sixteen known compounds. The structures of the isolated compounds were elucidated through detailed spectroscopic analyses, including 1D and 2D NMR techniques, and chemical methods. Compounds 2 and 5 showed modest anti-HIV-1 activities with EC₅₀ values of 2.23 µM and 4.36 µM, respectively, in comparison to the positive control.
