Curculigo crassifolia (Bak.) Hook. f. (Hypoxidaceae) is a tall perennial herb used as a folk medicine to treat child pneumonia by local people in Yunnan Province. Two new phenolic glycosides named crassifoside C (1) and crassifoside D (2) were isolated from the ethanolic extract of rhizomes of Curculigo crassifolia, and their structures were identified by 2D-NMR spectroscopic techniques and chemical transformations. In addition, seven known compounds (3 - 9) were isolated and identified by spectroscopic analysis and comparison of their spectral data with those reported previously.
