摘　　要：To study the chemical constituents in Bletilla ochracea Schltr. , repeated column chromatographies and preparative TLC were used for the isolation of compounds, and spectroscopic techniques （NMR, IR, UV and MS） were used for their structural identification. Seven compounds, 2,7-bis （ allyloxy ） -5-methoxy-3-methyl-9, 10-dihydrophenanthrene（1）, gastrodin（2）, gastrodigenin（3）, β-sitosterol（4）, stigmasterol（5）, 4-hydroxybernzaldehyde（6）, and daucosterol（7） were obtained from the roots of B. ochracea Schltr. Compound 1 is structurally illustrated as a novel compound, and the others are isolated from the title plant for the first time.To study the chemical constituents in Bletilla ochracea Schltr. , repeated column chromatographies and preparative TLC were used for the isolation of compounds, and spectroscopic techniques （NMR, IR, UV and MS） were used for their structural identification.
