Abstract

Rosmarinus officinalis L. (Lamiaceae), a Mediterranean aromatic plant, is valued in cosmetics, cuisine, and pharmaceuticals. This study investigates seasonal variations in essential oil (EO) composition and yield from R. officinalis harvested at Kosar University during 2023-2024. GC-MS and GC analyses revealed EO yields of 0.39-0.77%, with major compounds including α-pinene, camphene, limonene, camphor, and linalool. Seasonal shifts were observed: summer exhibited higher linalool and camphor, autumn peaked in verbenone and 3-octanone, and winter increased monoterpene alcohols (25.28%). Principal Component Analysis (PCA) distinguished three ecological groups (Group1: R₃; Group2: R₄, R₆, R₁, R₂; Group3: R₅), though intra-seasonal chemical differences within regions were minimal. These findings highlight the influence of seasonal dynamics on rosemary's phytochemical profile, offering insights for optimised harvest timing to enhance EO quality for industrial applications.

调查伊朗北呼罗珊省（Bojnord）迷迭香精油成分的季节变化：与现有文献的比较分析，重点是单萜醇成分。

迷迭香（Lamiaceae）是一种地中海芳香植物，在化妆品、烹饪和药品中都很有价值。本研究调查了2023年至2024年期间科萨尔大学采收的马蹄草精油（EO）成分和产量的季节性变化。气相色谱-质谱和气相色谱分析表明，精油的收率为0.39 ~ 0.77%，主要化合物包括α-蒎烯、樟烯、柠檬烯、樟脑和芳樟醇。季节变化：夏季芳樟醇和樟脑含量较高，秋季马鞭草酮和3-辛酮含量最高，冬季单萜醇含量较高（25.28%）。主成分分析（PCA）区分出3个生态类群（Group1: R3; Group2: R4, R6, R1, R2; Group3: R5），但区域内的季节性化学差异很小。这些发现强调了季节动态对迷迭香植物化学特征的影响，为优化收获时间以提高工业应用的EO质量提供了见解。

期刊介绍： The aim of Natural Product Research is to publish important contributions in the field of natural product chemistry. The journal covers all aspects of research in the chemistry and biochemistry of naturally occurring compounds. The communications include coverage of work on natural substances of land and sea and of plants, microbes and animals. Discussions of structure elucidation, synthesis and experimental biosynthesis of natural products as well as developments of methods in these areas are welcomed in the journal. Finally, research papers in fields on the chemistry-biology boundary, eg. fermentation chemistry, plant tissue culture investigations etc., are accepted into the journal. Natural Product Research issues will be subtitled either ""Part A - Synthesis and Structure"" or ""Part B - Bioactive Natural Products"". for details on this , see the forthcoming articles section. All manuscript submissions are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. All peer review is single blind and submission is online via ScholarOne Manuscripts.
