Analgesic and anti-inflammatory effects of the dry matter of culture broth of Termitomyces albuminosus and its extracts

Abstract

Aim of the study The objectives of this study were to investigate the analgesic and anti-inflammatory effects of the dry matter of culture broth (DMCB) of Termitomyces albuminosus in submerged culture and its crude saponin extract (CSE) and crude polysaccharide extract (CPE). Materials and methods The analgesic effects of DMCB, CSE and CPE were evaluated with models of acetic acid-induced writhing response and formalin test in mouse. The anti-inflammatory effects of DMCB, CSE and CPE were evaluated by using models of xylene-induced mouse ear swelling and carrageen-induced mouse paw edema. Results The DMCB, CSE and CPE significantly decreased the acetic acid-induced writhing response and the licking time on the late phase in the formalin test. Treatment of DMCB (1000 mg/kg), CSE (200 mg/kg) or CPE (200 mg/kg) inhibited the mouse ear swelling by 61.8%, 79.0% and 81.6%, respectively. In the carrageen-induced mouse paw edema test, the group treated with indomethacin showed the strongest inhibition of edema formation by 77.8% in the third hour after carrageenan administration, while DMCB (1000 mg/kg), CSE (200 mg/kg) and CPE (200 mg/kg) showed 48.4%, 55.6% and 40.5%, respectively. Conclusions The results suggested that DMCB of Termitomyces albuminosus possessed the analgesic and anti-inflammatory activities. Saponins and polysaccharides were proposed to be the major active constituents of Termitomyces albuminosus in submerged culture.
