  Ethnopharmacological survey was conducted in Galliyat areas of Tehsil Abbotabad (NWFP) Pakistan. Being apart from city the local people preferably use medicinal plants for their common ailments by traditional methods. Galliyat is dressed up with a wide range of medicinal flora. Indigenous plants are interactly associated to the culture and traditions of local peoples. So ethnopharmacological survey yielded interesting results. The survey comprised plant-collection trips, interviews and meetings with local people and rural herbalists. In a total of 41 wild plant species, belonging to 40 genera of 33 families were used by local inhabitants, for medicinal purposes.

  Haloxylon recurvum Bunge ex Boiss (Chenopodiaceae) is distributed chiefly from the Mediterranean region to Central and South Asia and traditionally applied externally for a variety of disorders. We investigated the in vivo toxic potential of crude methanolic extract of the whole plant and its n-hexane, chloroform, butanol, ethylacetate and aqueous soluble fractions by determining their acute toxicity and acute neurotoxicity in mice using Lorke`s method and inverted screen test. In vitro studies were also conducted in order to investigate its antilipoxygenase, antibacterial and antifungal activities. All the fractions showed a narrow margin of safety in mice, except the aqueous fraction, which did not produce any mortality even at the highest tested dose (5000 mg kg-1). At non-lethal doses, only the aqueous fraction (TD50 1264 mg kg-1) was found to produce neurotoxicity in mice. In in vitro lipoxygenase inhibition assay, the ethylacetate fraction showed the most significant inhibitory activity. Crude methanolic extract and its butanol soluble fraction showed the most potent antifungal and antibacterial activity for all the materials tested. Thus, this report verifies the traditionally reported toxicity of this plant, as the majority of its components have exhibited a narrow margin of safety, however, they have been found active in in vitro studies, therefore, further studies are required in order to isolate the most active toxic compounds and differentiate them from these fractions.

  The aim of this study was to determine the mineral contents of jamun fruit (Eugenia jambolana) products namely jam, squash, ready-to-drink juice, pulp powder and seed powder. The products were made and stored for 24 months at various storage conditions in different packaging material since it was an essential part of doctoral study carried out in 2007-2009. About 09 mineral elements such as Cr, Cu, Mn, Zn, Fe, Mg, Ca, Na and K in all jamun products were detected through atomic absorption spectrophotometer. The minimum and maximum macronutrients of Jamun products were determined as mg/kg. Two varieties of Jamun namely improved-V1 and indigenous-V2 were used. From the results of this study it could be concluded that there is a significant difference between the products as well between the cultivars however, VI is comparatively better than V2 in containing minerals.
