The biomass estimation parameters of Larix and Korean Pine have not obvious trend with stand age, while the BEF^ BCEF and R of Pinus sylvestris var. Mongolia decreases with the stand age increasing, and gradually stabilized.

Conclusion BCEF has antidepressant effects in depression mouse models. The mechanisms of its antidepressant effects may be related with the reinforcement of central monoamine neurotransmitter especially to 5-HT and NE nerves system.

结论BCEF在多种抑郁模型上具有一定的抗抑郁作用，可能与增强NE、5HT能神经系统有关。
