海芦笋籽油的检测及其性质的研究

Study on Measurement and Characterization of Salicornia bigelovii Torr. Seed Oil

为了明确海芦笋籽油的使用价值,对海芦笋种籽及其籽油的理化性质进行了研究。海芦笋种籽的含油率为26.01%,并对种籽中的水分,灰分,蛋白质,以及总碳水化合物质量分数进行测定。采用超声波溶剂法提取该种籽中的油脂,通过测定毛油的酸值,碘值,皂化值,过氧化值和不皂化物,来评估籽油的质量。运用GC-MS对籽油中的脂肪酸组成进行了分析,海芦笋籽油中主要的脂肪酸是亚油酸（64.02%）,以及不饱和脂肪酸总质量分数达到84.98%。采用HPLC方法,检测出海芦笋籽油中含有丰富的维生素E。同时,在200~400 nm处进行紫外扫描,得出海芦笋籽油可以作为一种广谱紫外线保护剂。结果表明：海芦笋籽油可以用于化妆品,医药和食品等领域。

Studies were conducted on properties of seeds and oil extracted from Salicomia bigelovii Torr. seeds. The percentage yield of oil was calculated as 26.01%. Some other measurements of the seeds like moisture,ash,protein and total carbohydrate content were also carried out. The acid value,iodine value,saponification value,peroxide value and unsaponifiable value were also determined to assess the quality of the seed oil. The fatty acid composition of this oil were analysed by GC-MS,and the main fatty acid was Linoleic （64.02%） and total unsaturated fatty acid was 84.98%. Salicornia bigelovii Torr. seed oil was rich in tocopherols detected by HPLC. The crude seed oil,which showed some absorbance in the UV（200-400 nm） range,can potentially be used as a broad spectrum UV protectant. It is concluded that the seed oil can be used in cosmetic, pharmaceutical and food products.
