Leaf Oils of Two New Avocado Varieties Endemic to Costa Rica

Abstract The leaf oils of two new montane varieties of Persea americana, endemic to Costa Rica were examined by GC/MS. The analysis of the volatiles showed the presence of 78 components, of which 62 were identified. Persea americana var. tilaranensis oil was characterized by a-phellandrene (14%), β-caryophyllene (21%), germacrene D (14%), β-elemene (8%) and valencene (5%). P. americanavar. costaricensis oils were characterized by germacrene D (26%), β-caryophyllene (21%), valencene (14%), α-phellandrene (3%) and β-elemene (3%).
