PHARMACOGNOSTIC AND DRUG EVALUATION PARAMETERS OF PINUS ROXBURGHII SARG

Abstract

The Pinus roxburghii Sarg (Pinaceae) is commonly known as chir pine. It is a large tree up to 28-55 m in height. The bark is red-brown, leaves are needle-like, in fascicles of three, very slender, distinctly yellowish green. The P.roxburghii is an economically valuable species, balancing the ecosystem of the Indian mountains. The plant have their own pharmaceutically importance. In traditional system of medicine different parts of the plant have been used for cough, cold, influenza, tuberculosis, bronchitis antiseptic, diaphoretic, diuretic, rubefacient, stimulant and vermifuge. Bark paste is used in burns. Resin is used to relieve cough and gastric troubles. Plant is used as intestinal antiseptic, hypolipidimic, antioxidant property. The present study was undertaken to assess pharmacognostic parameters and phytochemical screnning of bark of Pinus roxburghii Sarg. Organoleptic evaluation of bark were done by studying organoleptic features like shape, size,colour, odour, taste and fracture In microscopy the bark was soaking into water filled beaker so that sufficient moistening is obtained for microscopy. In powder microcsopy dried powdered material was obtained by grinding bark and visual under microscope taken at 100x .To evaluate the Physico chemical property the crude dried plant material was subjected to study the various parameters such as extractive value using different solvent pet ether, chloroform, methanol and water, also calculate the percentage yield of moisture content, ash value including acid insoluble, water soluble ash, fluorescence analysis and loss on drying etc were evaluated by using standard procedures. To evaluate the phytochemical screening of extracts the different solvents were used such as Sodium hydroxide, Chloral hydrate, Ferric chloride, Sulphuric acid, Iodine, Lead acetate, Magnesium, World Journal of Pharmaceutical Research SJIF Impact Factor 7.523 Volume 6, Issue 10, 1756-1770.
