(a) In crude extraction solutions; the inset demonstrates the corresponding HPLC analyses to calculate the contents of THSG in DI water-based and AuNT water-based solvents; *p < 0.05. (b) In extraction powder; the inset demonstrates the corresponding HPLC analyses to calculate the contents of THSG from DI water-based and AuNT water-based solvents; ***p < 0.001.
