| Abstract: | By surveying 83 cultivars of tea plants from tea germplasm nursery in Shaanxi province,epigallocatechin gallate(EGCG) content of tea was measured by high performance liquid chromatography(HPLC).Synthetic quality evaluation of 28 tea cultivars was conducted with four biochemical characteristics,including caffeine content,free amino acid content,tea polyphenol content and water extract content.The result showed that the content of EGCG ranged from 6% to 11%.The average content was 9.097% and there are 28 cult... |
