Abstract
We clarified the quality and properties of various components and lipids of Taiwan tea seeds (both large and round types) and Japanese tea seeds. The lipids of tea seeds were mainly composed of 90.7-94.4% neutral lipids with 3.6-7.4% glycolipids and 1.6-2.0% phospholipids. Among neutral lipids of tea seeds, the ratio of triacylglycerol was as high as 75.5-80%, whereas acylsterylglucosides were prefatty acids of tea seed lipids were shown ta be C18: 1, C18: 2 and C16: 0. Large amounts of 7-stigmastenol and β-anyrin were recognized in 4-desmethylsterol and 4, 4-dimethylsterol. α-Tocopherol alone was detected among tocopherol analogues.
