Abstract
For generating a strategy of quantitative and qualitative productions of invasive Lippia multiflora, influence of soil pH and the contents of organic carbon (C), total nitrogen (Nt), total (Pt) and available (Pa) phosphorus were explored via dominant-abundance (DAI) and aggregation (AI) index of the species as well as the leave extractable essential oil. In three sites (Labelekaha, Taoura and Zievogo) of L. multiflora ecosystem in north Cote d’Ivoire (Sudan savanna), corresponding DAI and AI were recorded coupled with soil and leave sampling at different topographic sections. Soil pH and the contents of C, Nt, Pt and Pa were determined as well as the concentrations of essential oils. Occurrence of L. multiflora was highest in the down slope position of the landscapes with significant influence of Pa also noticed for essential oils mainly characterized by highest concentrations of Geranial, Neral, a-Phellandrene, Para-Cymene, Limonene+B-Phellandrene and a-Humulene. The effect of soil organic C, and Nt were accounting for hydromorphic condition as occurred at Zievogo. The cultivation of L. multiflora may be possible in down slope position applying P for high yields of leaves and essential oils mainly composed of terpenoid derivatives. Further applications of organic C and N are required for hydromorphic soil.
Highlights
Lippia multiflora Mondenke is a woody shrub in tropical ecologies, with increasing interest because of its biomedical virtues: Tea-like infusions are traditionally used as remedy against malaria fever, stress, hypertension, gastro-intestinal trouble and caugh as well as laxative (Noamesi, Adebayo, & Bamgbose, 1985; Pham & Koffi, 1998; Jim, Wudeneh, Mariana, & Dan, 2000; Abena et al, 2003)
The cultivation of L. multiflora may be possible in down slope position applying P for high yields of leaves and essential oils mainly composed of terpenoid derivatives
In topsoil (0 – 20 cm), soil content of C (> 1 gkg-1) is high except for the soil in middle slope position contrasting with soil content of Nt, exclusively low (< 1 gkg-1) whatever the topographic position when compared with the critical level respectively
Summary
Lippia multiflora Mondenke (savanna tea) is a woody shrub in tropical ecologies, with increasing interest because of its biomedical virtues: Tea-like infusions are traditionally used as remedy against malaria fever, stress, hypertension, gastro-intestinal trouble and caugh as well as laxative (Noamesi, Adebayo, & Bamgbose, 1985; Pham & Koffi, 1998; Jim, Wudeneh, Mariana, & Dan, 2000; Abena et al, 2003). L. multiflora contains some adjutants for cosmetic (Porspi, 1992; Kanko, Sawaliho, Koné, Koukoua, & N’guessan, 2003) and pesticides (Oladimeji, Orafidiya, Ogunniyi, & Adewunmi, 2000; Oussou et al, 2008; Etienne et al, 2011) produces These qualities are attributed to the properties of the leaf extractable essential oils (Irvine, 1961) accounting for 42 volatile compounds from L. multiflora and more than 126 from Lippia spp. In the light of these utilities of the extractable chemical compounds of essential oil of Lippia spp., it may significantly contribute to the development of pharmaceutical and cosmetic manufacturing activities in its natural growing ecosystems, as observed in savanna zone of Sub-sahara Africa. This potentiality can substantially contribute to alleviation of poverty in this region where the population www.ccsenet.org/enrr
