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.
From the root of Daphne odora Thunb. (Chinese crude drug, Ruixanggen, Thymelaeaceae) three new flavans, daphnodorin A (1), daphnodorin B (2) and daphnodorin C (3) have been isolated. Their structures were established by chemical and spectroscopic means.
