Abstract
Litchi chinensis as an emerging crop of Pakistan is a member of Sapindaceae. The aim of this study was to evaluate the seed oil of Litchi chinensis by GC-MS analysis, physicochemical studies, antibacterial and antioxidant activities. The chromatogram of GC-MS indicated the presence of terpenoids, fatty acids and sterols. The main fatty acids observed were oleic acid (26.52 %), unusual fatty acid (16.14 %) and palmitic acid (8.54 %) of total composition. The iodine number, saponification number and free fatty acid values obtained were 42.3, 173.6 and 8.41 respectively. The antioxidant and antibacterial activities were carried out using DPPH assay and well diffusion method respectively. For antibacterial activity the best result of zone of inhibition (16 mm) was obtained against gram positive bacteria Bacillus subtilis. The result of antioxidant activity (79.1 %) proved it to be a very strong antioxidant.
