                 Abstract: To investigate the potential applications of the alcohol extract from Gymnadenia orchidisꎬ an in vitro study was
                 conducted to evaluate its antioxidant activity and antitumor activity using high ̄performance liquid chromatography
                 (HPLC)ꎬ biochemical analysis technologyꎬ and the MTT method. The results were as follows: (1) Gastrodin was
                                                                                ̄1
                 discovered in the alcohol extract from G. orchidisꎬ with a mass fraction of 2.5 mgg . The concentration of gastrodin in
                 the alcohol extract was 0.25%. (2) The alcohol extract from G. orchidis demonstrated a significant scavenging capacity
                                         +
                 towards hydroxyl radicalsꎬ ABTS radicalsꎬ and DPPH radicals. The efficacy of the alcohol extract from G. orchidis
                 becomed more pronounced with an increase in concentrationꎬ exhibiting a concentration ̄dependent response. The alcohol
                                                                                                     ̄1
                 extract from G. orchidis demonstrated the most substantial scavenging capacity at a concentration of 2.0 mgmL ꎬthe
                                                  +
                 scavenging rates for hydroxyl radicalꎬ ABTS radicalꎬ and DPPH radical were 81. 68%ꎬ 19. 94%ꎬ and 48. 16%ꎬ
                 respectively. In contrastꎬ gastrodin solely exhibited scavenging activity towards hydroxyl radicals and lacked such activity
                           +                                         ̄1
                 towards ABTS and DPPH radicals. (3) The IC of the 2.0 mgmL alcohol extract from G. orchidis on SMMC ̄7721

                 and HepG ̄2 were 5.170 mgmL and 4.551 mgmL ꎬ respectively. Similarlyꎬ the IC of BGC ̄823 and MKN ̄45 were
                                                                                 50

                 1.759 mgmL and 1.564 mgmL ꎬ respectivelyꎬ while the IC of MDA ̄MB ̄231 was 2.665 mgmL . Furthermoreꎬ
                                                                50

                 the IC of U251 was 4.401 mgmL . The alcohol extract from G. orchidis demonstrated significant inhibitory effects on

                 SMMC ̄7721ꎬ HepG ̄2ꎬ BGC ̄823ꎬ MKN ̄45ꎬ MDA ̄MB ̄231ꎬ and U251 cells. Notablyꎬ the inhibitory effects on BGC ̄823
                 and MKN ̄45 were the most pronouncedꎬ suggesting that the antitumor activity of the alcohol extract from G. orchidis
                 exhibited a wide range of efficacy. The above findings of this research demonstrate that the alcohol extract from G.
                 orchidis possesses antioxidant capabilitiesꎬ and its ability to scavenge reactive oxygen species is more extensive than that
                 of its antioxidant active componentꎬ gastrodin. Given the correlation between reactive oxygen species and tumorigenesisꎬ
                 the alcohol extract from G. orchidis was discovered to possess significant characteristics of antitumor and contributing to
                 the synergistic effects of natural plants through its multiple components. The alcohol extract from G. orchidis can
                 effectively inhibit the proliferation of various tumor cellsꎬ particularly those of human gastric cancer.
