We examined the effects of biological activity Phellinus linteus mycelium culture with cassiae semen extract. Firstly, the optimal temperature, initial pH and culture period for mycelial growth in a liquid culture of P. linteus were determined, and they were 30℃, pH 5.0 and 8 days respectively. The five herbal materials were examined against several health functional efficacies, and, as a result, Cassiae semen was chosen, with its superior inhibitory effects in β-glucuronidase inhibitory activity, electron donating activity, ACE inhibitory, and α-glucosidase inhibitory activities(95.3%, 80.9%, 96.1 and 24.2%, respectively). P. linteus fruit body was investigated on β-glucuronidase inhibitory activity, electron donating activity, ACE inhibitory, and α-glucosidase inhibitory activities, and they were 54.7%, 81.9%, 30.0% and 20.1%, respectively. Accordingly, C. semen was used in the following experiment, to give an additive functional effect on the P. linteus. As the amount of C. semen in the cultural media increased, mycelial weight and β-glucan contents also increased, but final pH was not influenced. In addition, the β-glucuronidase inhibitory activity, electron donating activity, and α- glucosidase inhibitory activity increased. P. linteus mycelium culture showed higher activities in the other three tests above, except for electron donating activity, when C. semen was added to the medium before cultivation.
