Experimental and Theoretical Study of the Raman Spectra of Ganoderic Acid T

Abstract

Ganoderic acid T (GAT) has many pharmacological functions such as antitumor and antimycobacterial activity. However, to the best of our knowledge, no commercial high-purity GAT is available and the experimental and theoretical study of the Raman spectrum of GAT has never been reported up to date. Therefore, in this work, we extracted GAT and purified from Ganoderma lucidum mycelia, measured its Raman spectrum and analyzed it based on the density functional theory (DFT) calculation at the B3LYP/6-311+G(d,p) level. The research on the molecular, structural, and spectral properties may provide deeper insights into the functions and better applications of GAT.
