Chemical constituents of selected Sudanese medicinal and aromatic plants

Abstract

Sudanese medicinal and aromatic plants (Alternanthra repens, Ambrosia maritima, Citrus paradisi, Croton zambesicus, Lepidium sativum, Morettia phillaena, Nauclea latifolia, Plectranthus barbatus, Pluchea dioscorides, and Sphaeranthus suaveolens) were analyzed for their chemical composition, mineral contents and secondary constituents. The concentration of manganese, copper, iron, nickel, lead, zinc and potassium in plant samples was performed using x-ray fluorescence spectrometry. The trace elements found in the smallest amount of the investigated plant species are lead, nickel and copper, while high concentration was detected for potassium, iron and manganese. Mn was accumulated with high level in Alternanthra repens species. Potassium was abundant in S. suaveolens and Ambrosia maritima. The values of concentration obtained for all studied elements were compared with published values of reference material, trace elements in Hay (powder) by International Atomic Energy Agency. Phyto chemical analysis of investigated plants was performed for constituents: Flavonoids, saponins, tannins, alkaloids, amino acids and sugars. The methanolic extracts of P.barbatus, C.paradisi, A.repens, N.latifolia, L. sativum and C. zambesicus are found to contain alkaloids. Results of TLC analysis were shown as R{sub f} values for saponins, bitter principles, essential oils, flavonoids and alkaloids. Quantification of flavonoids and tannins showed that flavonoid content was highest in case of  More>>

Results of TLC analysis were shown as R{sub f} values for saponins, bitter principles, essential oils, flavonoids and alkaloids. Quantification of flavonoids and tannins showed that flavonoid content was highest in case of Alternanthera repens and Sphaeranthus suavertens, whereas the highest tannin content was in case of Nauclea latifolia and Sphaearanthus suavertens. The results suggest that the user of traditional Sudanese crude drugs should be warned of potential danger of heavy metal poisoning because their concentrations seem to be higher than maximum values allowed by health agencies in several countries. This study has provided some biochemical basis for the ethno medical use of extracts from different candidate plant species in the treatment and prevention of diseases. As rich source of phytochemicals and minerals these plants can be a potential source of useful drugs, and also used as bio indicators to follow changes in an environmental pollution.(Author)}
