α-Glucosidase Inhibitory and Antioxidant Potential of Morchella Mushroom
한국버섯학회 버섯 제23권 1호 통권 39호 2019.06 p.54
Morchella (morels) have been used as herbs through history, and current scientific research confirmed their various health benefits. However, as an edible fungus, information regarding the chemical composition of morels is limited. In our present study, the methanolic extract of Morchella showed α -glucosidase inhibitory activity. Chromatographic separation of the n- hexane fraction which had the highest α-glucosidase inhibitory activity led to the isolation of (Z,Z)-9,12-octadecadienoic acid as a major compound. Further study revealed that (Z,Z)-9,12-octadecadienoic acid showed strong α-glucosidase inhibitory activity. On the other hand, since different fractions may contain different types of constituents which contribute to the biological activities, we investigated the antioxidant activity of the fractions. Ethyl-acetate fraction showed the most potent antioxidant activity. Further quantitation of total phenol and flavonoids contents revealed a positive correlation between the content of these compounds and antioxidant activity. Taken together, these results provide important information for the understanding of the edible qualities of the morel fruiting body. Moreover, the functional characterization of morel constituents may contribute to the diversity of these mushroom in the field of food industry.

Phellinus linteus strains ASI 26099 (Korea Sanghwang, PLKS), KACC93057P (Hankyong Sanghwang, PLHS), HN6036 and P. baumii (Jangsoo Sanghwnag, PBJS), were artificially cultivated on oak wood logs in a mushroom house under the same condition. The two years old fruiting bodies were used for analyzing bioactive efficacies. The crude polysaccharides from fruiting bodies of PLHS showed high proliferative activity in LPS (lipopolysaccharide) -activated RAW 264.7 cell at 125-100μg/mL when compared to those of other varieties. The polysaccharide samples inhibited cytokines, IL-6 and TNF-α production of 43-63% in the cell dependent on concentrations of 125-1000μg/mL. The PLHS showed high inhibitory effect of 20-45% on HCT116 human colon cancer cells at concentration of 125 μg/mL-1000 μg/mL when compared to that of 3-39% of PBJS.
