These macro-minerals in mulberry and cherry fruits (DW) at the analyzed stages ranged from 2349 to 5150, 1460 to 5100, 1265 to 4375 and 1457 to 3160, 1247 to 2950, 1025 to 2900 mg/kg, respectively. Overall, the concentrations of these minerals were found to be decreased as the fruit maturity progressed. However, K content in some cases increased as fruit ripened. The investigated fruits also contained considerable amounts of micro-minerals such as Zn, Fe, Mn, Al, and Cu. The distribution of micro-minerals also virtually followed the similar trends as exhibited by the macro minerals. ANA-O12 CHEMICAL COMPOSITIONS AND BIOLOGICAL ACTIVITIES OF THE ESSENTIAL OILS OF THREE OCIMUM SPECIES COLLECTED FROM DIFFERENT GEOGRAPHICAL REGIONS OF PAKISTAN 1,2 AI Hussain, SAS Chatha, J Worthington and A Jabbar 1 2 1 2 Department of Chemistry, Govt. College University, Faisalabad, Pakistan School of Biomedical Sciences, University of Ulster, Colerain, BT52 1SA, Northern Ireland, UK E-mail: ai.hussain@yahoo.com 1 Different species of Ocimum are frequently used as a food in different Asian dishes. The aim of the present study was to examine the variation in the yield, chemical composition and biological activities of essential oils of three Ocimum species, grown at hilly and plane regions of Pakistan. The essential oils contents of Ocimum sanctum, O. gratissimum and O. basilicum, collected from hilly regions were 0.90, 1.32 and 1.00 % were slightly higher than from plane regions 0.52, 0.90 and 0.70 %, respectively. The GC-MS analysis revealed fluctuation in the contents of most of the chemical components of the essential oils investigated, with respect to species and regions. The major chemical constituent of O. sanctum, O. gratissimum and O. basilicum essential oil from hilly and plane regions were eugenol (18.9 and 27.3 g/100 g), β-caryophyllene (18.7 and 20.5 g/100 g), β -elemene (15.6 and 12.0 g/100 g); eugenol (46.1 and 55.1 g/100 g), germacrene D (9.70 and 5.61 g/100 g); linalool (47.8 and 29.4 g/100 g), eugenol (8.33 and 15.5 g/100 g), 1,8-cineol...
