“…These levels are low compared to those obtained by the authors [27] [33] in Camellia senensis teas. The low sodium content of teas and herbal teas could be used in the treatment of hypertension and renal disease according to [34]. The potassium levels of herbal teas and green teas are higher than those of sodium.…”

This study aims to determine the mineral composition of green teas and herbal tea in the savannah tea plant. Samples of buds, young leaves and broadleaf stems were collected from wild plants of Lippia multiflora in three localities, including two from the Center (Yamoussoukro, Toumodi) and one from the northeast (Bondoukou) of Côte d'Ivoire. The lipid and ash contents were carried out by the AOAC method. The total protein and sugar contents were determined by the Kjeldahl and Agbo methods, respectively. Nine minerals (potassium, calcium, magnesium, iron, sodium, manganese, zinc, copper and cadmium) were quantitated by Atomic Absorption Spectrophotometry (AAS) from green teas (buds and young leaves) and herbal tea of Lippia multiflora.The results showed that ash levels (7.05% -13.94%) and protein (6.22% -9.97%) were high, however the lipid contents (1.01% -2.98%) and total sugars (1.43% -4.51%) are low. Majority of the minerals are calcium (2320.91 to 36150.10 mg/kg), potassium (2110.71 to 12174.67 mg/kg) and magnesium (3620.87 -5870.46 mg/kg). Iron (52.55 to 483.11 mg/kg), sodium (35.66 to 469.16 mg/kg) and manganese (15.25 to 76.86 mg/kg) are represented in average proportions. There are small amounts of zinc (9.61 -47.50 mg/kg), copper (5.66 -8.71 mg/kg), and cadmium (0.17 -1.49 mg/kg). Lippia multiflora herbal teas and green teas are low in fat, high in ash and are good sources of protein and minerals.

“…Ash content (5.70%) was lower than the 7.14% obtained by Dike [3]. The ash of a food stuff is the inorganic residue remaining after the organic matter has been burnt away [10]. The ash content shows the leaves to be rich in mineral elements such as Na, Mg, Ca, Fe, etc.…”

The proximate, elemental and phytochemical compositions of the leaves of Pterocarpus soyauxii (Oha) were studied. The results obtained for the proximate composition showed the following: moisture content (17.2%), ash content (5.7%), crude fibre (17.2%), crude protein (29.5%), crude fat (4.15%) and carbohydrates (25.95%). The results of the mineral (elemental) analysis in mg/L showed the following to be present in the leaves: Ca (4.04), Cu (0.20), Zn (1.39), Mg (41.0), K (0.31), Mn (0.17), Na (32.0) and Fe (0.60) with Pb and Cr absent. The leaves also contained vitamin A (0.2044 mg/g) and vitamin C (0.4470 mg/g). The phytochemical analysis of different solvent extracts showed the presence of alkaloids, saponins, glycosides and tannins. Flavonoids, phenols and steroids were absent. These findings showed that the leaves of Pterocarpus soyauxii are good sources of beneficial micronutrients, mineral elements and secondary metabolites which are required for healthy growth, justifying the use of the leaves for the popular "Oha" soup of the Igbos of South East Nigeria.

“…Fibre intake can stimulate weakening hunger, peristaltic movement and lower the serum cholesterol level [26,34]. Iwuji and Nwafor [35] reported that high fibre content in food can cause intestinal irritation and lower nutrient bioavailability. Lipid content recorded from this work shows that the plant contains 12.52% lipids.…”

“…This shows that the plant have potential health benefit as proteins are essential for the synthesis of body tissues and regulatory substance such as enzyme and hormones. According to Emebu and Anyika [35] carbohydrates are pivotal nutrients required for adequate diet. The carbohydrate composition of Cnidoscolus aconitifolius leaf obtained from this study shows that the plant leaf contains 40.05%.…”

The present study evaluated nutritional constituents of Cnidoscolus aconitifolius leaf and examined the effect of aqueous and ethanol extracts on selected biochemical parameters using male albino rats. Forty five male albino rats weighing (115-121g) were used for the study. The rats were randomly divided into nine groups of five rats each. Group I served as the control while the other groups were administered 200, 400, 600 and 800mg/kg body weight of aqueous and ethanol leaf extracts. Mineral, proximate and vitamin analysis showed that the plant leaf contains appreciable amount of vitamin and minerals analysed. Results showed significant difference (P<0.05) between the control and Cnidoscolus aconitifolius leaf extracts administered rats with respect to body weight changes, liver function indices and hematological parameters (White Blood Cells) in dose dependent ratio. From this study, aqueous leaf extract of Cnidoscolus aconitifolius at doses of 400, 600 and 800mg/kg body weight showed evidence of cumulative toxicity. It is therefore suggestive to say that in order to ensure holistic safe utilization, bioactive constituents of Cnidoscolus aconitifolius leaf may be better extracted using ethanol as it has not shown any evidence of hepatotoxicity.
