Abstract

Artemisia scoparia Waldst. et Kit. is a member of the Asteraceae family that spread widely throughout the world, especially, in Southwest Asia and Central Europe. Terpenoids are members of interesting components in this plant. The current study was carried out to evaluate the morphological, agronomical, and phytochemical traits of A. scoparia in different plant densities. The essential oil was extracted by Clevenger and its components were identified by GC/MS. The results were shown, the morphological, agronomical, and phytochemical indices, include plant height, lateral branching, fresh and dry weight of the aerial part, essential oil content (% v/w), essential oil yield (ml/m2), and essential oil composition enhanced by plant density and showed significant differences between different levels of plant densities. The highest essential oil content (2 ml/100g dry matter) and essential oil yield (10.19 ml/m2) was observed in 30×30 cm and 30×40 cm plant densities, respectively. Investigation of essential oil composition showed that the different plant density has an impact on the quality of essential oil with influenced the content of important compound groups such as oxygenated monoterpenes (1,8-cineole, artemisia ketone, artemisia alcohol, and camphor), monoterpene hydrocarbons (α-pinene, camphene, β-pinene, and myrcene), and sesquiterpene hydrocarbons (1,3,8-ρ-menthatriene, and β-selinene) by 63.53 to 68.08 %, 22.48 to 28.81 %, and 5.0 to 6.39 %, respectively. According to the results, we can generally say that 30×40 cm density is considered as the most suitable density due to a higher essential oil yield of the species studied (A. scoparia).

密度依赖性影响青蒿的农艺指标和化学特性。套件

摘要

蒿(Artemisia scoparia Waldst)。et Kit。是菊科家族的成员,该家族广泛分布于世界各地,尤其是在西南亚和中欧。萜类化合物是该植物中有趣成分的成员。进行了当前的研究,以评估不同植物密度下番茄的形态,农艺和植物化学特性。Clevenger提取了香精油,GC / MS鉴定了其成分。结果表明,形态,农艺和植物化学指标包括植物高度,侧枝,地上部分的鲜重和干重,精油含量(%v / w),精油产量(ml / m 2)),精油成分随植物密度而增加,并且在不同密度的植物之间显示出显着差异。最高的精油含量(2 ml / 100g干物质)和最高的精油产量(10.19 ml / m 2)分别在30×30 cm和30×40 cm的植物密度中观察到。对香精油成分的研究表明,不同的植物密度会影响香精油的质量,并影响重要化合物组的含量,例如氧化单萜(1,8-桉树脑,青蒿酮,青蒿醇和樟脑),单萜碳氢化合物(α-pine烯,camp烯,β-pine烯和月桂烯)和倍半萜烯碳氢化合物(1,3,8-ρ-薄荷烯和β-selinene)分别增长63.53%至68.08%,22.48至28.81%和5.0至6.39 %, 分别。根据结果​​,我们通常可以说30×40 cm的密度被认为是最合适的密度,因为所研究的物种(A. scoparia)的精油产量更高。
