A new 2,7-type cyclolignan glycoside, cyclolignanyingoside A (1), together with six known compounds (2-7) were isolated from the tubers of Pinellia ternata (Thunb.) Breit. The structure of 1 was elucidated on the basis of chemical and spectral analysis, including 1D, 2D NMR analyses, HR-ESI-MS, and CD spectrometry. The cytotoxic, antioxidant and tyrosinase-inhibiting activities of all the isolates were determined. However, all the isolates exhibited no activity on the selected cell lines (Hep-3B, Bcap-37, and MCF-7). In addition, compounds 1-3 and 7 exhibited strong 2,2-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) free radical scavenging activity, and compounds 2 and 4 showed a moderate mushroom tyrsinase inhibitory activity.
