Triacylglycerols-Analysis of Three Medicinal Seed Oils Using Pancreatic Lipase

摘要

The fatty acids distribution pattern in triacylglycerols of three medicinal seed oils viz. Ipomea biloba (Convolvulaceae), Argemone mexicana (Papaveraceae) and Holarrhena antidysentrica (Apocynaceae) were determined using pancreatic lipase hydrolysis method. All the three seeds contain a high percentage of unsaturated acids (I. biloba- 52.94%; A. mexicana-82.68%; H. antidysentrica- 93.15%). I. biloba contains relatively greater amount of saturated acids (47.06%) than other two seeds. The lipolytic data revealed that linoleic acid dominates at 2-position of triacylglycerols whereas the other two seeds i.e. A. mexicana and H. antidysentrica show almost similar pattern of distribution with oleic acid preferentially acylated at 2-position.
