Abstract
|
|
|
|
In this study, we evaluated the fatty acid composition and physiological activities of oils extracted from eight types of seeds, pepper (Capsicum annuum L.), green tea (Camellia sinensis L.), perilla (Perilla frutescens var. japonica Hara), peanut (Arachis hypogaea L.), cotton (Gossypium indicum LAM.), sesame (Sesamum indicum L.), walnut (Juglans regia L.), and safflower (Carthamus tinctorius L.). The composition and quality analysis showed that the oils were potentially suitable for foo-grade applications. The composition analysis showed that the oils were mostly composed of unsaturated fatty acids including linoleic acid and oleic acid. In 3T3-L1 adipocytes, green pepper, perilla, and peanut seed oils inhibited lipid accumulation, and green pepper, perilla, peanut, sesame, walnut, and safflower seed oils induced leptin secretion. These results show that the inhibitory effect of edible seed oils on lipid accumulation, and induction of leptin secretion may be useful for obesity management.
