A new a bisflavan-3-ol, boerhavianane (1), was isolated from Boerhavia elegans L. The structure of the flavanol dimer was elucidated by detailed spectroscopic analysis including 1H, 13C NMR, COSY, HMQC, HMBC, and ESI-MS. Boerhavianane (1) was evaluated for its anticancer activity and demonstrated a significant reduction in the viability of breast cancer cells in a concentration-dependent manner with an IC50 value of 38.48 μg/mL. Moreover, boerhavianane (1) was also screened for DPPH antioxidant activity and acetyl cholinesterase, xanthine oxidase, urease, and α-glucosidase enzyme inhibition activities. Preliminary results showed that it exhibited significant inhibition (81.0 ± 2.0%) against urease enzyme, whereas for DPPH radical scavenging it showed moderate activity (75.0 ± 1.5%).
