Aim: Stress relaxant and antioxidant activities of ethanolic extract of fruit Spondias mangifera (EEFSM) and its isolated compound (Sm-01) were evaluated. The structure of Sm-01 was also elucidated. Materials and Methods: EEFSM at two different doses of 100 and 200 mg/kg (bw)/day and Sm-01 at dose of 10 mg/kg (bw)/day were screened for in vivo stress relaxant activity using anoxia stress tolerance, swimming endurance and cyclophosphamide-induced immune suppression model and in vitro antioxidant activity using 1,1-diphenyl-2-picrylhydrazyl (DPPH) model. The levels of Hb, red blood cell (RBC) and white blood cell (WBC) along with organ and body weights suppressed by cyclophosphamide were estimated. The structure of Sm-01 was elucidated by spectroscopy (ultraviolet, infrared, 1H-nuclear magnetic resonance [NMR], 13C-NMR and mass spectrometry) and chemical analyses. Results: Sm-01 was structurally elucidated as propan-1,2-dioic acid-3-carboxyl-β-D-glucopyranosyl-(6'→1")-β-D-glucofuranoside. It was found that EEFSM and Sm-01 significantly increased the anoxia stress tolerance, swimming endurance and duration of stay on rotarod and normalized the levels of Hb, RBC, and WBC along with altered organ and body weights suppressed by cyclophosphamide. EEFSM and Sm-01 also exhibited significant antioxidant activity against DPPH free radical at the concentrations of 0.05, 0.5, and 1.0 mg/mL with obtained IC50of 0.32 and 0.15 mg/mL, respectively. Conclusions: These findings demonstrated that extract and Sm-01 both possess significant stress relaxant and antioxidant activities favoring its use as adaptogens. The activities of the extract may be due to the Sm-01.
