Table 1.
Relative intensity of various metabolites in the methanol (MeOH) and distilled water (DW) extracts of Chamaecyparis obtusa leaves. All data are presented as mean ± standard error of the mean of five replicates. * p < 0.05 (student’s t-test); ** p < 0.01 (Student’s t-test). RT, retention time; ND, not detected.
