Lipid Studies of Carum Roxburghianum Seeds
Amran Waheed,Shahid Mahmud,Muhammad Saleem,Muhammad Yamin,Muhammad Naeem Khan 한국생약학회 2003 Natural Product Sciences Vol.9 No.3
Total lipids extracted from the powdered seeds of Carum roxburghianum were fractionated into hydrocarbons (0.30%), wax esters (0.30%), sterol seters (1.35%), triacylglycerols (72.41%), free fatty acids (6.06%),1,3-diacylglycerols (4.60%), 1,2-diacylglycerols (0.64%), glycolipids (5.10%), sterols (1.20%), 2-monoacylgylcerols ,(3.18%), 1-monoacylglycerols (1.46%), phosphatidylethanolamines (1.08%) phosphatidylchlines (0.40%), lysophosphatidylethanolamines (1.48%) and phosphatidylinositols (0.44%) with the help of TLC. The fatty acid composition ao all the lipid fractions was determined after converting them into their methy1 esters with BF_(3)-methanoll reagent and then analyzing them by GC. Oleic acid was found as a major component in all the lipid classes, whereas palmitic, linoleic and linolenic acids were present in lesser quantities. Arachidic acid was identified as a minor component in only seven out of twelve lipid classes.
Studies on the Lipid Classes of Nicotiana tabacum L. Seed Oil
Amran Waheed,Shahid Mahmud,Muhammad Akhtar Javed,Muhammad Saleem 한국생약학회 2001 Natural Product Sciences Vol.7 No.4
The lipid classes constituents; hydrocarbons, wax esters, sterol esters, triacylglycerols, free fatty acids, 1,3-diacylglycerols, 1,2-diacylglycerols, free sterols, 2-monoacylglycerols, 1-monoacylglycerols, phosphatidylethanolamines, phosphatidylcholines, lysophosphatidylethanolamines and phosphatidylinositols of Nicotiana tabacum L. seeds oil were investigated by thin layer and gas chromatography. Palmitic, oleic and linoleic acids were the major components in all lipid classes studied.
Activity of Lipase and Phospholipase Extracted from the Seed Meal of Nicotiana tabacum L.
Amran Waheed,Shahid Mahmud,Muhammad Saleem 한국생약학회 2001 Natural Product Sciences Vol.7 No.1
The activity of the lipase and phospholipase extracted from the seed meal of Nicotiana tabacum L. was studied with the help of Spectrophotometer at different pH, Temperatures and Solvents. Both lipase and phospholipase shown optimum activity at pH 6 and 45℃. Their activities also maximize when n-heptane was used as solvent media.
