The oil of spp. has become a well-known high-quality edible oil because of its rich nutrition. It is of great significance to breed fine varieties of spp. for the sustainable growth of the spp. industry. This study mainly evaluated the quality and antioxidant capacity of the camellia seed from several sources. The fatty acid composition and main active components of 40 kinds of , , , and seeds, and so on, from different regions, were tested using GC-MS and HPLC. The quality of different spp. germplasm resources was comprehensively evaluated using multiple indices. The unsaturated fatty acid content and the antioxidant capacity of from Hainan were higher than those of Abel. In addition, there were a few differences in the fatty acid compositions of spp. oil from different species. Correlation analysis confirmed that rutin, total saponin, total flavonoids, squalene, and vitamin E were strongly correlated to the antioxidant capacity of spp. In the comprehensive evaluation, the best quality and strongest antioxidant activity were found for Chengmai Dafeng (). These methods in the study were applied for the first time for the quality evaluation of the Camellia spp. species. This study provided new insights into the quality evaluation of the spp. species, thus facilitating further development of variety breeding along with quality evaluation.
由于其丰富的营养， 属植物的油已成为一种广为人知的优质食用油。培育 属植物的优良品种对 属植物产业的可持续发展具有重要意义。本研究主要对几种来源的油茶种子的品质和抗氧化能力进行了评价。采用气相色谱-质谱联用仪（GC-MS）和高效液相色谱仪（HPLC）对来自不同地区的40种 、 、 、 种子等的脂肪酸组成和主要活性成分进行了检测。利用多个指标对不同 属种质资源的品质进行了综合评价。海南 的不饱和脂肪酸含量和抗氧化能力高于阿贝尔 。此外，不同种 属植物油的脂肪酸组成存在一些差异。相关性分析证实，芦丁、总皂苷、总黄酮、角鲨烯和维生素E与 属的抗氧化能力密切相关。在综合评价中，澄迈大丰（ ）的品质最佳，抗氧化活性最强。本研究中的这些方法首次应用于油茶属物种的品质评价。该研究为油茶属物种的品质评价提供了新的见解，从而有助于品种选育和品质评价的进一步发展。
