Comparative analysis of cultivation characteristics and functional constituents of five varieties of Sanghuangporus baumii

The mycelial growth rate, primordial differentiation time, agronomic traits and yield, the content of polysaccharides, total flavonoids, total triterpenes and total phenols of fruiting bodies of five varieties of Sanghuangporus baumii were determined and compared, as well as their scavenging ability on ABTS⁺ free radicals, DPPH free radicals and hydroxyl free radicals. The results showed that under the same culture condition, there were differences in mycelium growth rate, primordial differentiation time, agronomic characters, yield, active constituents and antioxidant capacity among different S. baumii varieties. S. baumii HN01 has the fastest growth speed, with good growth vigour, rapid differentiation of primordia, good agronomic characters and high yield, and the next best is S. baumii SW. The content of polysaccharides, total flavonoids, total triterpenes and total phenols in S. baumii SW fruiting body is relatively high, and the antioxidant capacity of its active components is the strongest, while the next best is S. baumii HN01. Comprehensive comparison of the total active substances (yield × active ingredient content) among the five cultivated varieties showed that the total crude polysaccharide content of S. baumii HN01 was comparatively high, and the total phenol content of S. baumii SW was comparatively high, while the total flavonoids and total triterpenoids of the varieties were similar. The two varieties, HN01 and SW, could be used as excellent varieties for large scale production.
