Physiochemical screening and comparison of mineral composition of leaves from broadleaf and longleaf morphotypes of Lippia multiflora Moldenke (Verbenaceae) cultivated of Côte d’Ivoire

Abstract

The phytochemical screening and mineral analyze of longleaf morphotype (llmLM) and broadleaf morphotype (blmLM) of Lippia multiflora cultivated in 3 localities of the Côte d'Ivoire such Bondoukou (Bdk), Béoumi (Bmi) and Korhogo (Krg) were carried out. The aims of this study were to provide information on the therapeutic and nutritional values of this herbal tea according the plant origin. Results showed presence of bioactive compounds like alkaloids, tannins and flavonoids in the extracts. All of the extracts were rich in condensed tannins. Concerning flavonoids, flavone was high grade in extracts from Bondoukou and Béoumi while the highest levels of flavanols were found in extracts from Korhogo. Essentials minerals like calcium, magnesium, sodium, potassium, manganese, phosphorus, zinc, iron, and Cooper was presents in leaves and extracts. In addition, the levels of both of this mineral in extract were below the maximum level permissible suggested by World health organization (1989). We noted also the variability of both components according the cultivation areas. The presence of phytochemicals components and mineral elements in the aqueous extracts of Lippia multiflora contribute to their therapeutics application in medicinal practices and their nutritional importance. However, the variability among the phytochemical profiles of samples from different areas express their different medicinal, pharmacologic and nutritional properties.
