Two sterols and seven triterpenoids were isolated and identified from Ganoderma lucidum by silica gel column chromatography, preparative high-performance liquid chromatography and spectra analysis. Then, the multidrug resistance reversal activities of these compounds were assessed using MTT assay. Among these compounds, ganoderol B (3), ganoderone A (4), ganodermanondiol (6) and ganoderiol F (8) were shown to reverse the resistance of human oral epidermoid carcinoma cell line KBv200 to doxorubicin, and the reversal folds were 6.59, 4.70, 4.01 and 7.09, respectively. Ganoderiol F could increase the intracellular accumulation of doxorubicin in KBv200 cells through inhibiting P-glycoprotein transport function. Further mechanistic investigation found that ganoderiol F did not alter P-glycoprotein expression. In conclusion, ganoderiol F has potent effect in reversing P-glycoprotein mediated tumor multidrug resistance. Potential reversal agents against multidrug resistance in tumor may be found in triterpenoids from Ganoderma lucidum.
