Abstract

Fats of in the seeds of six oil-tea camellia superior clones species GLR-CY3、GLR-CY4、GLR-CY27、GLR-CY53、GLR-CY56 and GLR-CY166 were extracted using the Soxhlet extractor.The ratios of the crude fats on a dry basis in the six oil-tea species were 39.13 %,42.71 %,44.69 %,60.18%,48.07% and 50.60%,respectively.The fatty acids composition and content of these six species were analyzed by gas chromatography.The results indicated that the main components are unsaturated fatty acids in seed of oil-tea camellia superior clones and the content of oleic acid were the highest in the fatty acids of them.The relative amounts of unsaturated fatty acids to their total amount of the fats were 90.16% for GLR-CY166,89.81% for GLR-CY4,89.12% for GLR-CY53,88.69% for GLR-CY27,88.47% for GLR-CY3 and 83.61% for GLR-CY56 respectively.Tea-oil is a good resource for food or medicine.The analysis means that a sound ground has been laid down for the molecular breeding of oil-tea at the same time.
