Abstract

Decoctions (DECs) and hydro-alcoholic extracts (HEs) prepared from roots of Boerhaavia diffusa L. (Nyctaginaceae) and Curculigo orchioides Gaertn. (Hypoxidaceae) were phytochemically characterised by HPLC-DAD and profiled for their antioxidant, antigenotoxic and cytotoxic activities. B. diffusa DEC was rich in ferulic acid and vanillin, while the HE also contained boeravinone B and eupalitin. Both C. orchioides HE and DEC displayed the main occurrence of orcinol-β-d-glucoside and curculigoside A. Antioxidant activity was assayed through spectrophotometric DPPH, ABTS and β-carotene bleaching test, and using (HP)TLC bioautographic strategies. For both crude drugs, HE was the best performing preparation. Properly modified SOS-Chromotest evidenced a 10% inhibition by phytocomplexes against 4-nitroquinoline-N-oxide, and a higher bioactivity for vanillin (36.60 ± 1.68%) and ferulic acid (35.09 ± 1.53%). C. orchioides HE was the preparation which showed higher cytotoxicity against drug-sensitive human T-lymphoblastoid cell line (CCRF-CEM) and multidrug-resistant leukaemia cell line (CEM/ADR5000), and eupalitin was the only pure compound to exhibit an IC50 value.
