Medicinal plants have a significant role in preventing and curing several diseases, and Tanacetum L. is one of these plants. The aim of the present study is to determine the fatty acid, lipid-soluble vitamin, sterol, phenolic content, and antioxidant capacity of Tanacetum densum subsp. laxum and Tanacetum densum subsp. amani, to compare the effect of altitude on the biochemical content and to compare systematically by using fatty acids and phenolics. This study showed that palmitic acid (C16:0) and stearic acid (C18:0) are major sources of saturated fatty acid and oleic acid (C18:1 n9), and linoleic acid (18:2 n6c) and a-linolenic acid (C18:3 n3) are the principal unsaturated fatty acids in the two endemic Tanacetum densum taxa. Also, this study found that the unsaturated fatty acid content (60.11±1.61%) of Tanacetum densum subsp. laxum was higher than the unsaturated fatty acid content (44.13±1.28%) of Tanacetum densum subsp. amani. And also, the ω6/ω3 ratio of Tanacetum densum subsp. laxum (1.74) and Tanacetum densum subsp. amani (1.60) was found to be similar. However, this study determined that the lipid soluble vitamin and sterol content of two endemic Tanacetum taxa are low except for stigmasterol. Present study showed that catechin is principal phenolic in the Tanacetum densum taxa. This study also found that Tanacetum densum subsp. laxum and Tanacetum densum subsp. amani had the highest levels of catechin, vanillic acid, and caffeic acid content though the phenolic amounts, particularly catechin and quercetin, were dissimilar in the T. densum taxa. This study suggested that ecological conditions such as altitude may affect the biochemical content of two endemic Tanacetum densum taxa. Furthermore, the current study determined that two endemic Tanacetum L. taxa had potent radical scavenging capacities and found a correlation between total phenolics and antioxidant activity.

地方性艾菊（实验室）Schultz Bip的生化含量和抗氧化能力。亚种 laxum和Tanacetum densum（实验室）Schultz Bip。亚种 阿曼尼·海伍德（Amani Heywood）生长在土耳其

药用植物在预防和治愈多种疾病中起着重要作用，而艾叶草是这些植物之一。本研究的目的是确定艾菊（Atanacetum densum）亚种的脂肪酸，脂溶性维生素，固醇，酚含量和抗氧化能力。泻药和艾叶草牙本质亚种。amani，以比较海拔高度对生化含量的影响，并通过使用脂肪酸和酚类进行系统比较。这项研究表明棕榈酸（C16：0）和硬脂酸（C18：0）是饱和脂肪酸和油酸（C18：1 n9）以及亚油酸（18：2 n6c）和α-亚麻酸的主要来源（C18：3 n3）是两种地方性艾菊（Stanacetum densum）类群中的主要不饱和脂肪酸。此外，该研究还发现了艾叶艾菊（Atanacetum densum）亚种的不饱和脂肪酸含量（60.11±1.61％）。Laxum高于Tanacetum densum亚种的不饱和脂肪酸含量（44.13±1.28％）。阿曼尼。并且，艾菊的亚种的ω6/ω3比率。Laxum（1.74）和Tanacetum densum亚种。阿曼尼（1.60）被发现是相似的。然而，这项研究确定了两个地方性艾菊类群的脂溶性维生素和固醇含量较低，除了豆甾醇。目前的研究表明，儿茶素是艾菊中的主要酚类。这项研究还发现了艾菊密齿亚种。泻药和艾叶草牙本质亚种。阿马尼（Amani）的儿茶素，香草酸和咖啡酸含量最高，尽管在T. densum分类群中酚类的含量，尤其是儿茶素和槲皮素的含量不同。这项研究表明，诸如海拔等生态条件可能会影响两种地方性艾美特丹（Stanacetum densum）类群的生化含量。此外，当前的研究确定了两种地方性的艾美生紫苏类群具有有效的自由基清除能力，并且发现了总酚类和抗氧化剂活性之间的相关性。
