Abstract:

Avocado (Persea Americana) also known as butter fruit has numerous medicinal properties and is beneficial to health. The pulp and seed were extracted using chloroform and ethanol. The phytochemical analysis determined the presence of alkaloids, flavonoids, tannins and saponins. In avocado pulp, alkaloids and flavonoids were present in a higher concentration and in seeds, cardiac glycoside and tannins showed lower concentration. Macro molecules such as carbohydrates, proteins and fatty acids were determined. In pulp and seed, fatty acid showed higher concentration while proteins showed the lesser concentration in pulp and seed; carbohydrates however were present in the same concentration. Phenolic contents, cholesterol and amino acid were determined. Amino acid and phenolic content showed higher concentration in case of pulp and seed whereas cholesterol was present in small amount. The extraction of oil was carried out by means of cold extraction process .The lipid profile of avocado oil was determined which included the estimation of cholesterol, fatty acid, iodine number and saponification number. Iodine number was high in pulp and seed. Fatty acid value and acid value were the same in pulp and seed. Saponification number was also the same for seed and pulp.

Keywords: Avocado Cold extraction process Ethyl lactate Fatty acid Macromolecule
