Abstract
Mushroom extracts are a new source of supplements for health and pharmaceutical due to their bioactivities. This study was to optimize the extraction parameters of a soluble polysaccharide from Auricularia polytricha (SPAP) by response surface methodology. The practical optimum parameters were an extraction time of 4h, an extraction temperature of 95 °C and a ratio of water to fruiting bodies of 28 mL/g, and the highest extraction rate was 19.77%. In vivo, male Sprague-Dawley (SD) rats were diet-induced hypercholesterolemic models and oral administration of SPAP to evaluate anti-hypercholesterolemic effects. The results showed that SPAP decreased the serum concentrations of blood lipid, made them close to the normal level. The total cholesterol in the SPAP consumption groups was significantly decreased 34.6 ± 7.6% and 33.3 ± 7.9% with dose of 4.5 and 9.0mg/kg BW in the 29th day. This study suggested that SPAP was a suitable natural agent and may be applied in therapy.Entities:
