Three new flavans, daphnodorin A(1), daphnodorin B(2) and daphnodorin C(3), as well as four known coumarins, daphnetin, daphnoretin, umbelliferone and daphneticin, were isolated from the root and the bark of Daphne odora THUNB. The plane structures of 1 and 2 were established by chemical and spectroscopic means.
从香堇菜(Daphne odora THUNB.)的根和树皮中分离出三种新的黄酮:达夫诺多林A(1)、达夫诺多林B(2)和达夫诺多林C(3),以及四种已知的香豆素:达夫酮、达夫诺瑞丁、伞花素和达夫酮。化学和光谱方法确定了1和2的平面结构。
