3.1. Biochemical analysis of plant Due to the presence of bioactive compounds‚ medicinal plants have special properties of treatment of various chronic diseases. Lonicera quinquelocularis is used medicinally in the treatment of different diseases as “alternative medicine”. Due to the medicinal uses of the plant‚ it is very important to explore the biochemical composition of the plant. 3.1.1. Plant Collection Plant of Lonicera quinquelocularis was collected from the area Kakki of district Bannu‚ Khyber

horizontal wells are used to inject high pressure steam into the Clearwater Formation‚ which warms the bitumen oil viscosities(100-10‚000 cp) at reservoir temperature and lowers its viscosity thereby permitting it to flow into the well bore. . Figure 1 shows a typical relationship between the viscosity of a heavy‚ viscous crude oil and temperature. As can be seen‚ for certain crude oils‚ viscosities decrease by orders of magnitude with an increase in temperature of 100–200◦F. This suggests that if the temperature

by an inorganic acid usually H2SO4 Purpose: In this lab Methanol alcohol and Salicylic acid were reacted together to form Methyl Salicylate. This was done to determine the characteristic odour of the Methyl Salicylate. Safety: Safety goggles must be worn at all times. Methanol: Toxic‚ may be fatal if inhaled‚ ingested or absorbed through skin. -Highly flammable: will be easily ignited by heat‚ sparks or flames. When handling Methanol: follow instructions issued by the instructor. - Wear safety

Title: Starch Aims 1. To identify starch in food. 2. To study the microscopic appearances of raw and heated starch. 3. To compare the viscosity of various gelatinized starch solutions. Introduction Starch is one of the most abundant substances on the earth. It can be found in seeds‚ grains‚ and roots of many crops where it is synthesized in granular form. Starch granules are packages of starch molecules. The importance of starch is well-known‚ as is its central role in human diet.
