The optimal harvest time was associated with the maximum yield of pharmacological compounds with the most potential interest for health. Anti-inflammatory activity apparently correlated with chemical profiles of essential oils and the geographic origins of the plants. Statistical analysis of the chemical profiles and monthly evolution of the three sites over a period of one year allowed assessment of variations in composition and the subsequent choice of the optimal harvest time for ethnopharmacological applications. One essential oil chemotype corresponded to the LPA and LPT sites and one corresponded to the LPB site. The results indicated that chemical profiles and essential oil yields vary according to the location where the plants were cultivated. Anti-inflammatory properties were also assessed against activated macrophages in vitro. These data were then analyzed using Principal Component Analysis (PCA). Essentials oils (n=36) were then extracted from these samples by hydro-distillation according to the European Pharmacopoeia and qualitatively and quantitatively analyzed using GC/FID and GC/MS. Standard plants (n=40) were re-introduced into natural plots, cultivated for 12 months and leaves were sampled monthly in a standardized fashion. Natural Lippia multiflora seeds were sourced to produce standardized plants over a period of six months. Experimental plants were cultivated at Abidjan (LPA), Toumodi (LPT) and Bondoukou (LPB). Therefore, the present study aimed to identify chemical variations in essential oils of Lippia multiflora as a function of geographic origin and time of annual harvest to determine optimal chemical profiles for ethno-pharmacotherapeutic applications. The potential effects of plants on health are associated with their chemical composition. Lippia multiflora is a plant with nutritional and pharmaco-therapeutic properties that is native to central and occidental Africa.
