Aims: To evaluate the application of spent Pleurotus ostreatus substrates, enriched or not with medicinal herbs, as a source of anti-inflammatory compounds.
Subjects and Methods: P. ostreatus was cultivated on five different substrates: Barley straw (BS) and BS combined 80:20 with medicinal herbs (Chenopodium ambrosioides L. [BS/CA], Rosmarinus officinalis L. [BS/RO], Litsea glaucescens Kunth [BS/LG], and Tagetes lucida Cav. [BS/TL]). The anti-inflammatory activity of aqueous extracts of spent mushroom substrates (SMSs) (4 mg/ear) was studied using an acute inflammation model in the mouse ear induced with 2.5 μg/ear 12-O-tetradecanoylphorbol13-acetate (TPA).
Results: Groups treated with BS/CA, BS/RO, and BS/LG aqueous extracts exhibited the best anti-inflammatory activity (94.0% ± 5.5%, 92.9% ± 0.6%, and 90.4% ± 5.0% inhibition of auricular edema [IAO], respectively), and these effects were significantly different (P < 0.05) from that of the positive control indomethacin (0.5 mg/ear). BS/TL and BS were also able to reduce TPA-induced inflammation but to a lesser extent (70.0% ± 6.7% and 43.5% ± 6.6% IAO, respectively).
Conclusions: Spent P. ostreatus substrate of BS possesses a slight anti-inflammatory effect. The addition of CA L. to mushroom substrate showed a slightly synergistic effect while RO L. had an additive effect. In addition, LG Kunth and TL Cav. enhanced the anti-inflammatory effect of SMS. However, to determine whether there is a synergistic or additive effect, it is necessary to determine the anti-inflammatory effect of each medicinal herb.
