摘要
以新疆的两种罗布麻为原材料,采用有机溶剂提取法并结合气相色谱-质谱联用仪(GC-MS),比较和分析二茬次罗布白麻和罗布红麻叶不同采收期的精油含量与化学成分的差异,采用峰面积归一法确定其成分种类及各成分的相对含量.结果表明:二茬次罗布红麻叶精油含量显著高于二茬次罗布白麻叶精油,不同采收期的罗布白麻和罗布红麻叶精油提取率、成分种类、成分数量存在较大差异,其中10 月的二茬次罗布红麻叶精油含量最高.两种二茬次罗布麻叶及不同采收期精油均检测出含量较高的叶绿醇(Phytol)、新植二烯(Neophytadiene)、植物醇(3,7,11,15-Tetramethyl-2-hexadecen-1-ol)、2,4-二叔丁基苯酚(2,4-Di-tert-butylphenol)、正十六烷酸(n-Hexadecanoic acid)等.研究认为,二茬次罗布红麻叶适合药用,罗布白麻更适用于化妆品行业,且二茬次罗布红麻叶最佳采收期为9 月,二茬次罗布白麻叶最佳采收期为10 月.
Abstract
Using two types of Apocynum from Xinjiang as raw materials,organic solvent extraction combined with gas chromatography-mass spectrometry(GC-MS)was employed to compare and analyze the differences in essential oil content and chemical composition of the leaves of second harvest Apocynum venetum L.and Poacynum hendersonii(Hook.f.)Woods at different harvesting periods.The peak area normalization method was used to determine the types of components and their relative contents.The es-sential oil content of the second harvest Poacynum hendersonii(Hook.f.)Woods leaves was significantly higher than that of the second harvest Apocynum venetum L.leaves.There were significant differences in the extraction rate,component types,and component quantities of the essential oils from the leaves of the two types of Apocynum at different harvesting periods,with the highest content of essential oil found in the second harvest Poacynum hendersonii(Hook.f.)Woods leaves in October.Both types of second harvest Apocynum leaves and the essential oils from different harvesting periods were found to contain high levels of Phytol,Neophytadiene,3,7,11,15-tetramethyl-2-hexadecen-1-ol,2,4-di-tert-butylphenol,and N-hexadecanoic acid.The leaves of second harvest Poacynum hendersonii(Hook.f.)Woodsare suitable for medicinal use,while the leaves of second harvest Apocynum venetum L.are more suitable for the cosmetics in-dustry,with the optimal harvesting period for the former being September and the latter being October.
