Abstract

The aerial parts of Artemisia judaica L. (A. judaica) and Artemisia monosperma (Delile) (A. monosperma) were collected from wild plant populations located in the eastern desert of Egypt. The essential oils (EOs) of both aerial parts were isolated by hydro-distillation (HD) and analyzed by GC/MS. The EO yields of A. judaica and A. monosperma were 6.0 and 4.0 ml/500 g herb, respectively. Piperitone (43.8 % ± 3.6), artemisia ketone (38.3 % ± 3.2) and artemisia alcohol (3.1 % ± 0.6) were the main components of A. judaica EO, while the major components of A. monosperma EO were β-pinene (56.4 % ± 4.8), δ-cadinene (18.4 % ± 2.1), α-pinene (6.8 % ± 0.9), limonene (5.4 % ± 1.1) and cis-β-ocimene (3.1 % ± 0.5). Various constituents of A. judaica EO belonged to monoterpene hydrocarbons (MH) and oxygenated monoterpenes (OM). The chemical groups of A. monosperma EO were MH, OM, sesquiterpene hydrocarbons (SH), and oxygenated sesquiterpenes (OS). The major chemical classes of A. judaica and A. monosperma EOs were OM (90.3 % ± 6.1) and MH (77.4 % ± 4.9), respectively.

摘要

地上部分蒿欧蓍草L.（A.欧蓍草）和蒿monosperma（Delile）（A. monosperma）从位于埃及东部沙漠野生植物种群收集。通过加氢蒸馏（HD）分离两个地上部分的香精油（EOs），并通过GC / MS进行分析。菊苣和单精种子的EO产量分别为6.0和4.0 ml / 500 g草药。哌啶酮（43.8％±3.6），青蒿酮（38.3％±3.2）和青蒿醇（3.1％±0.6）是拟南芥EO的主要成分，而单精子EO的主要成分EO为β-pine烯（56.4％±4.8），δ-卡丁烯（18.4％±2.1），α-pine烯（6.8％±0.9），柠檬烯（5.4％±1.1）和顺式-β-西oci烯（3.1％±0.5） ）。犹他曲霉EO的各种成分分别属于单萜碳氢化合物（MH）和含氧单萜（OM）。A. monosperma EO的化学基团是MH，OM，倍半萜碳氢化合物（SH）和氧化倍半萜烯（OS）。犹他曲霉和单精曲霉EO的主要化学类别分别为OM（90.3％±6.1）和MH（77.4％±4.9）。
