The essential oil from the leaves of Phyllanthus salviaefolius H. B. K. (Euphorbiaceae) collected in February 2007 at Mucurubá (Mérida State) was analyzed by GC/MS. The yield of oil extracted by hydrodistillation was 0.005%. Sixteen components were identified, which represent 94.6% of the oil. Phytol (21.5%), β-citronellol (17.7%), trans-geraniol (13.5%), cis-3-hexenol (12.6%) and 1-hexanol (11.3%) were the most abundant components.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
