Characterisation of indole alkaloids and phenolic acids from wild mushroom and its chemical profiles compared with other Sanghuang mushrooms.

Two new indole alkaloids, 1-methylindole-7-methoxy-3-carboxaldehyde () and 7-methoxyindole-3-carboxaldehyde (), together with 7-methoxyindole-3-carboxylic acid methyl ester ( and 1-methylindole-3-carbaldehyde () were isolated from the fruiting bodies of wild Sanghuang mushroom (TL663). TLC, H-NMR and LC-MS chemical profiles of this mushroom compared with other three genera of wild Sanghuang mushroom extracts were investigated. The TLC, H-NMR and LC-MS profiles of TL663 and (SS664) were similar and significantly different from other mushrooms.
