摘要：

The rare earth elements Nd, La, Ce at proper concentrations had positive effects on the cell growth of Cistanche deserticola and production of phenylethanoid glycosides (PeG). A mixture of rare earth elements (MRE, La2O3:CeO2:Pr6O11:Sm2O3 = 255:175:3: 1, mol/mol) showed the most remarkable effects. After 30 day's culture, 0.02 mmol l(-1) MRE gave the highest content (20.8%) and production (1.6 g l(-1)) of PeG, which were 104 and 167% higher than those obtained in control (without rare earth elements).
