| Abstract: | From the branch tissue of Cephalotaxus mannii, the endophytic fungal strain CMM was isolated and determined to belong to the genus Aspergillus according to its internal
transcribed spacer (ITS) sequence of rDNA (ITS1-5.8S-ITS2). From the extracts of the fermentation broth of CMM, a new compound,
namely 5-O-α-D-glucopyranosyl-5-hydroxymellein (1), was isolated, together with a known compound 4-hydroxymellein (2). Their structures were elucidated on the basis of 1D and 2D NMR data.
