Abstract

|
This study investigated the physiological effects of three species of Auricularia known as Auricularia polytricha (JNM21001), Auricularia auricula-judae black (JNM21002), and Auricularia auricula-judae brown (JNM21012). In the ORAC assay, Auricularia spp. showed antioxidant activities in the order of JNM21001>JNM21012>JNM21002. All Auricularia spp. strongly inhibited the action of α-amyloglucosidase up to 60%. In order to further test in vivo anti-obesity effects, high fat diet induced ICR obese mice fed a diet containing 20% fat were used. All Auricularia spp. supplementation during high fat diet feeding significantly reduced body weight gain, epididymal fat pads weight, and lowered the food efficiency ratio compared to the high fat control (HFC) group. In particular, the group fed with JNM21012 had a lower average daily body weight gain of 0.45 g/day, demonstrating similar levels to the normal diet fed group. The group fed with JNM21012 significantly reduced lowered serum triglycerides (42%), total cholesterol (81%), and LDL-cholesterol level (66%) compared with the HFC group.
