Figures & Tables

Figure 1.

Characterisation of Morchella fluvialis. Phylogenetic analysis was conducted based on ITS1 and ITS4 sequence data. The length of the branches corresponds to the cumulative number of nucleotide substitutions in the DNA sequences under analysis. The sequences were obtained from GeneBank and EMBL databases, and their corresponding accession numbers are given within brackets.

Figure 2.

Effects of total extract and different fractions of M. fluvialis on α-glucosidase inhibitory and antioxidant activities. All data are presented as mean ± SEM (n = 3). *p < 0.05 and **p < 0.01, ***p < 0.001 indicates significant differences compared to the control group.
