Abstract
Due to their pharmacological importance, the prospection of natural products from Primulaceae species has increased significantly in the past years. Among such natural products, essential oils are especially noteworthy within the family. Here, we analyzed and presented the essential oil composition from two Myrsine species, Myrsine squarrosa and M. glazioviana, for the first time. The major components in M. squarrosa essential oil were cadinol (11 %); trimethyl heptadienol (7.0 %); methyl salicylate (6.0 %); spathulenol (4.6 %); γ-octalactone (4.4 %), and tricosane (4.0 %), while the major components from M. glazioviana essential oil were hexadecanoic acid (10.7 %); α-cadinol (10.4 %); epi-α-cadinol (8.0 %); α-acorenol (4.2 %) and spathulenol (3.4 %). α-Cadinol was the major component in both species. Based on PCA, the essential oil composition was related to the location where species were collected.
