中文摘要:
      为选育油茶优良无性系，利用核磁共振方法测定了玉屏38个油茶优良无性系的种子和种仁含油率，采用GC-MS/MS方法检测了索氏提取的油茶种仁油脂肪酸组成及相对含量。结果表明：MZ-3、YP-1、6-57、6-48和GY的种子和种仁含油率分别在41%和56%以上。油茶种仁油中检测出6种脂肪酸，分别为棕榈酸、硬脂酸、油酸、亚油酸、亚麻酸和花生烯酸，油酸含量高于83%的品系有5-35、5-37、6-49、XL-210和YP-1。这不仅为玉屏油茶优良无性系的选择提供了科学依据，而且可为油茶籽油的加工利用提供参考。
英文摘要:
      In order to select superior clones of Camellia Oleifera, oil content of 38 superior clones of Camellia Oleifera seeds and kernels in Yuping were examined by NMR method and fatty acid composition and content of the Soxhlet extracted Camellia Oleifera kernel oil were determined by GC-MS/MS method.The results showed that oil contents of seeds and kernels of MZ-3, YP-1, 6-57,6-48 and GY were above 41% and 56% respectively. Six kinds of fatty acids were detected from Camellia Oleifera kernel oil, which were palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid and arachidoinc acid. The oleic acid content of more than 83% of strains were 5-35,5-37,6-49,XL-210 and YP-1. It not only provided scientific basis for the selection of superior clones of Camellia Oleifera in Yuping, but also provided reference for the processing and utilization of Camellia Oleifera seed oil.
