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.展开更多
