New source for L-iditol and taxanes

We describe the first report of the recovery of L-iditol and Taxane from an angiosperm- Yunnanopilia longistaminata (W.Z.Li) C.Y.Wu et D.Z.Li (Opiliaceae). Two taxane compounds and L-iditol were isolated from the tender burgeon of Yunnanopilia longistaminata, and their structure were identified as Taxayunnansin B, Taxumairol E and L-iditol on the basis of NMR and MS spectrum, respectively. It is a new plant source for L-iditol and taxanes.
