Geranial and Neral, Major Constituents of<i>Lippia multiflora</i>Moldenke Leaf Oil

Abstract

ABSTRACT The leaf oils of samples of Lippia multiflora Moldenke collected from different geographic areas of Togo and from cultivated plants were analyzed by GC and GC/MS. Three types of essential oils were characterized, one which is rich in neral and geranial, (23–89%) and two other types, poor in neral and geranial, containing either 1,8-cineole (16–63%) or thymol (15–40%) and p-cymene (15–20%) as the major components. The oils obtained exhibited insecticidal activity against the bruchid Callosobruchus maculatus Fab. in a dose-dependent manner.
