Opis:
The leaves of mistletoe (Viscum album) harvested from oil bean tree (Pentaclethra macrophylla) in Imo State South Eastern Nigeria was studied. The study was aimed at carrying out trace metal, Fourier Transform Infra-red (FTIR) and phytochemical analysis of ethanol leave extracts of Viscum album harvested from Pentaclethra macrophylla. The sample for trace metal analysis was digested with a mixture of concentrated HNO3 and HClO4 at a ratio of 1:1 for 24 hours. Ethanol was then used to extract the sample meant for FTIR and phytochemical analysis. Herein, trace metal determination indicates the presence of Mg, Zn, Fe, Cu and Cr, and the concentration of Ca and Mn is at < 0.00 mg/kg. The result of the phytochemical screening demonstrates the presence of flavonoids, alkaloids, phenols, saponins and tannins. FTIR analysis confirmed the presence of alcohols, amides, aromatics and carbonyl compounds in ethanol extracts of Viscum album harvested from Pentaclethra macrophylla. The presence of some trace metals and phytochemicals, as well as some important functional groups in the plant sample, as indicated by the result of the study, authenticates its use in traditional medicine.

Opis:
In the recent time there is an increase in the use of medicinal plants for treatment of ailments. This is owning to availability and low cost of herbal materials, which has increased the use of plants such as Viscum album for medicinal purposes. These plants may contain mineral elements, important phytochemicals and functional groups for healthy leaving, but increased use of this plant could lead to magnification of the mineral elements. Therefore, leaves of mistletoe (Viscum album) harvested from kola nut tree (Cola nitida) in Imo state, South Eastern Nigeria was studied. The study was aimed at determining the elemental content, phytochemicals as well as Fourier Transform Infra-red (FTIR) analysis of petroleum ether and chloroform extract of Viscum album harvested from Cola nitida. The sample for elemental analysis was digested with mixture of concentrated nitric acid (HNO3) and perchloric acid (HClO4). Petroleum ether and chloroform were used as solvents to extract the sample used for phytochemical and FTIR analysis. Elemental content analysis indicates that Ca, Cr, Cu, Fe, Mg, Mn and Zn were present at varying concentrations. The elemental content is in the order Fe > Mn > Cu > Mg >Zn > Cr > Ca. The presence of flavonoids, alkaloids, phenols, saponins and tannins were confirmed by the phytochemical screening. FTIR analysis indicates that alcohols, amides, aromatics and carbonyl compounds are present in the chloroform and petroleum ether extract of Viscum album harvested from cola nitida, though at different intensities. The presence of some essential minerals as well as some phytochemicals and some important functional groups must have necessitated the use of this plant for medicinal purposes.
