Through instrumental neutron activation analysis (INAA) the elemental chemical composition of Salvinia auriculata and Ouro Preto city public water was determined. Elements Ce, Th, Cr, Hf, Sb, Sc, Rb, Fe, Zn, Co, Au, La and Br were quantified. High chromium concentration was determined in this plant. But, chromium was determined only in low concentrations in the water. The results indicate the g...

Primula veris L. is an important medicinal plant with documented use for the treatment of gout, headache and migraine reaching back to the Middle Ages. Triterpenoid saponins from roots and flowers are used in up-to-date phytotherapeutic treatment of bronchitis and colds due to their expectorant and secretolytic effects. In addition to the wild type plants with yellow petals, a red variant and a...

The relationship between heavy metal concentrations of soil and plant (Senna auriculata) in the hills roadsides was studied. Atomic absorption spectroscopy used for determination metals such as lead (Pb), chromium (Cr), cadmium (Cd), zinc (Zn), copper (Cu), iron (Fe) (leaves flowers) samples. results showed that roadside samples were much greater than hills. It is evident concentration a are co...

the study was conducted to compare the effects of feeding acacia auriculata (aa), gmelina arborea (ga), albizia lebbeck (al) and butryospermum parkii (bp) tree forages as a sole feed for nigerian goats. four goats (yankasa) averaging one year and weighing 11.7±1.8 kg were used to measure the feed intake, digestibility and nitrogen balance. the leaves were offered ad libitum. dry matter (dm) int...
