| 中文摘要: |
| 在前期调查与文献查阅的基础上，对广东南岭国家级自然保护区的非粮油脂植物资源进行了初步调查和统计分析。对收集的植物含油器官采用索氏提取法测定含油率，气相色谱-质谱法测定油脂中的脂肪酸组成。结果表明：广东南岭国家级自然保护区非粮油脂植物共有77科190属471种，分别占南岭种子植物科、属、种的41.18%、17.40%、14.81%，分别占全国油脂植物科、属、种的71.30%、47.86%、57.86%；含15种以上非粮油脂植物的优势科有樟科、卫矛科、大戟科、芸香科、木兰科、茶科、蔷薇科，主要分布于海拔1 400 m以下的常绿阔叶林带；科属分布区类型复杂多样，以热带成分占明显优势，同时也受温带成分较强烈的影响；含油率大于45%的有46种（20科27属）。 |
| 英文摘要: |
| The non-food oil plant resources in Nanling national nature reserve in Guangdong were surveyed primarily and statistically analyzed based on early investigation and literature review. The oil content and fatty acid composition of energy storage organs of collected plants were determined by Soxhlet extraction and gas chromatography-mass spectrometry respectively. The results showed that 471 species belonging to 190 genera and 77 families distributed in this reserve，accounting for 14.81%，17.40% and 41.18% of the species，genera and families of the seed plants in Nanling respectively，and accounting for 57.86%，47.86% and 71.30% in Chinese oil plants. The dominant families of non-food oil plant which had species above fifteen were Lauraceae，Celastraceae，Euphorbiaceae，Rutaceae，Magnoliaceae，Theaceae and Rosaceae，mainly distributing in evergreen broad-leaved forest zone at altitude of below 1 400 m. The distribution elements of family and genera of the non-food oil plants in this reserve were complex and diverse，and tropical taxon was predominant，at the same time，temperate taxon affected strongly. The oil contents of 46 species belonging to 27 genera and 20 families were higher than 45%. |
