This is the first phytochemical investigation of Schisandra tomentella A. C. Smith. 11 lignans and 8 sesquiterpenoids, were isolated from the stems of S. tomentella, including two undescribed lignans, tomentaschinins A-B (1-2), and two new sesquiterpenoids, tomentaschinnes A-B (3-4). Their structures were elucidated based on the interpretation of their spectroscopic data. Cytotoxicity and MDR reversal effect of these compounds were screened on multidrug resistance cancer cell line MCF-7/ADR, and results showed gomisin M2 (7) could promote the efficacy of adriamycin against MCF-7/ADR.
