Energy density analysis was-applied to 25 species of Calophyllum coumarins. When the principal component analysis was performed by using energy density as variables, the 25 coumarins were classified into six groups. The first and second principal components were related to the substituent effect and the molecular skeleton, respectively. The molecular skeletons sufficiently influence anti-HIV-1 activities of coumarins rather than the substituents.
