A study on elemental contents of medicinally important species of Artemisia L. (Asteraceae) found in Pakistan

Journal of Medicinal Plants Research 11/2010; 4(21):2256-2263.

ABSTRACT Genus Artemisia is cosmopolitan in distribution and its several species are being used in folk therapeutic treatments worldwide. In this study, elemental compositions of seventeen indigenous species (A. scoparia, A. absinthium, A. indica, A. santolinifolia, A. maritime, A. vulgaris, A. japonica, A. nilagirica, A. herba-alba, A. annua, A. brevifolia, A. moorcroftiana, A. dracunculus, A. roxburghiana and A. dubia) that are commonly used against ailments in Pakistan were studied for the first time through atomic absorption spectrophotometry methods. In this study we observed nine trace elements namely Zn, Cu, Cr, Ni, Co, Cd, Pb, Mn, Fe and four major elements that are K, Na, Ca and Mg in these species. Further it is observed that in few sepses the concentration of heavy metals are found over and above the normal concentration levels than the international safety standards prescribed for medicinal plants. This study also discusses the impacts of heavy metal toxicity in humans.

    ABSTRACT: than synthetic drugs. Plant based traditional knowledge has become a recognized tool in search for new sources of drugs and neutraceuticals. The ethno botanical knowledge can bring out many different clues for the development of drugs to treat various human diseases. Characterization of extracts of medicinal plants is necessary, due to its numerous benefits to science and society. The information obtained, makes pharmacological studies possible. It also enables structure related activity studies to be carried out, leading to the possible synthesis of more potent drugs which reduce the toxicity. The mode of action of the plants producing the therapeutic effect can also be better investigated if the active ingredients are characterized. Therefore it is of interest to investigate the preliminary phytochemical analysis of Artimesia amygdalina, Nerium odorum and Strychnos potatorum which are known medicinal plants.

    ABSTRACT: The level of accumulation of selected essential and non-essential metals, namely; Ca, Cu, Fe, Zn, Mn, Cd, Pb, and Cr have been investigated in the seeds, fruits, and flowers of some medicinal plants utilized for tapeworm treatment in Ethiopia and their respective soil samples. These include seed of Cucurbita maxima (Duba), fruit of Embelia abyssinica (Ankoko), flowers of Hagenia abyssinica (Kosso), and fruits of Rosa abyssinica (Kega) and their respective soil samples. A wet digestion procedure with a mixture of conc. HNO3 and HClO4 for the plant samples and a mixture of conc. HNO3, HCl, and H2O2 for soil samples were used to solubilize the metals. Ca (1280–12,670 mg kg−1) was the predominant metal followed by Fe (104–420 mg kg−1), and Zn (18–185 mg kg−1) in all the plant materials except for Hagenia abyssinica flower from Hirna in which Mn (16–42 mg kg−1) followed by Fe. Among the non-essential toxic metals, Pb was not detected in Cucurbita maxima of Boji, Gedo and Hirna origins and in Rosa abyssinica of Hirna site. Similarly, Cr was not detected in Rosa abyssinica fruits of Boji and Gedo sites. The sampled soils were found to be between strongly acidic to weakly basic (pH: 4.7–7.1). In the soil samples, Ca (8528–18,900 mg kg−1) was the most abundant metal followed by Fe (417–912 mg kg−1), Zn (155–588 mg kg−1), Mn (54–220 mg kg−1), Cr (21–105. mg kg−1), Cu (11–58 mg kg−1), Pb (13–32 mg kg−1) and Cd (2.8–4.8 mg kg−1). The levels of most of the metals determined in the medicinal plants and the respective soil samples are in good agreement with those reported in the literature and the standards set for the soil by various legislative authorities.

    ABSTRACT: Artemisia plants had been used to treat many diseases. While there many controversies concerning their effects on the cardiovascular system, Artemisia extracts could be envisaged as anti-hypertensive and to prevent cardiovascular damages. In raison of its bare toxicity, using the crude extracts will be of much importance in this field.
