ABSTRACT
To develop a potent anti-obesity lipase inhibitor from mushroom, the lipase inhibitory activities of various mushroom extracts were determined. Methanol extracts from Phellinus linteus fruiting body exhibited the highest lipase inhibitory activity (72.8%). The inhibitor was maximally extracted by treatment of a P. linteus fruiting body with 80% methanol at 40degrees C for 24 hr. After partial purification by systematic solvent extraction, the inhibitor was stable in the range of 40~80degrees C and pH 2.0~9.0. In addition to lipase inhibitory activity, the inhibitor showed 59.4% of superoxide dismutase-like activity and 56.3% of acetylcholinesterase inhibitory activity.

In an effort to develop novel mushroom-derived anti-obesity nutraceuticals, water and ethanol extracts containing the lipaseinhibitory compound from Phellinus linteus were prepared, and their nutritional components were determined. The optimal conditions for the extraction of P. linteus lipase inhibitor involved the treatment of the fruiting bodies with distilled water at 80degrees C for 72 hr and 80% ethanol at 100degrees C for 60 hr, respectively. The distilled water extract and ethanol extract contained 10.9% and 6.11% of crude protein, and 0.96% and 15.86% of crude fat, respectively. Additionally, the distilled water extract contained a large quantity of minerals, including 239.5 mg of K, 39.3 mg of Mg, and 39.3 mg of Na. The free amino acid content of the distilled water extracts was also higher than that of the ethanol extracts, and in particular, the distilled water extracts contained 5,139 mg of asparagine, 3,891 mg of tryptophan, 2,598 mg of alanine, and 2,066 mg of serine in 100 g of the distilled water extracts. 100 g of the distilled water and ethanol extracts were found to contain 12.31 g and 8.16 g of malic acid, respectively.
