(S)-(+)-linalool is a non-cyclic oxygenated monoterpene which is very useful and widely used in the cosmetic industries, especially in the production of perfume and cologne. Thus, due to the high commercial value and high demand, the search for new plant sources rich in (S)-(+)-linalool in agricultural systems to develop the business of this compound is of great interest. This investigation focused on the diversity of phenotypic yield and phytochemical traits in Grammosciadium platycarpum populations collected from fourteen geographical regions in Iran. The goal was to identify the essential compounds and select the best populations for domestication, cultivation, and future breeding programs. The highest coefficient of variation was observed in the umbrellas per plant, plant length, internode length, leaf width, number of lateral branches, and essential oil yield (EOY). The shoot dry weight ranged from 27.15 to 41.56 (g/plant) and the fruit dry weight from 9.23 to 20.80 (g/plant) among different populations, which was observed in the QOR population. The fruit of the plant was employed to extract and determine the content plus constituents of the essential oil. The essential oil content (EOC) exhibited a extend from 0.81 to 1.63%. MAQ population indicated the maximum and OSH population revealed the minimum EOC. The highest EOY (0.228 g/plant) was observed in the MAQ population and the lowest (0.083 g/plant) was related to the MAR population. Based on GC-MS and GC analysis, 91.97 to 99.93% of the essential compounds of different populations of G. platycarpum were identified. According to the results, linalool (65.90-81.62%) and limonene (9.73-15.34%) were the main ingredients of the essential oil profile. Rutin, ferulic acid, and chlorogenic acid were detected as the major phenolic compounds using HPLC. The high diversity observed among different populations of G. platycarpum provides good potential for selecting the best populations and using them in domestication projects, cultivation, and breeding programs.
（S）-（+）-芳樟醇是一种无环氧化单萜，非常有用且广泛应用于化妆品行业，尤其是香水和古龙水的生产。因此，由于其高商业价值和高需求，在农业系统中寻找富含（S）-（+）-芳樟醇的新植物来源以发展该化合物的业务具有重大意义。本研究聚焦于从伊朗14个地理区域收集的宽果沙芥种群的表型产量和植物化学特征的多样性。目标是确定主要化合物，并选择最佳种群用于驯化、栽培和未来的育种计划。观察到单株伞数、株高、节间长度、叶宽、侧枝数和精油产量（EOY）的变异系数最高。不同种群间地上部干重范围为27.15至41.56（克/株），果实干重范围为9.23至20.80（克/株），这在QOR种群中观察到。该植物的果实用于提取和测定精油的含量及成分。精油含量（EOC）范围为0.81%至1.63%。MAQ种群的EOC最高，OSH种群的EOC最低。MAQ种群的EOY最高（0.228克/株），MAR种群的EOY最低（0.083克/株）。基于气相色谱 - 质谱联用（GC-MS）和气相色谱（GC）分析，鉴定出宽果沙芥不同种群91.97%至99.93%的主要化合物。结果表明，芳樟醇（65.90% - 81.62%）和柠檬烯（9.73% - 15.34%）是精油成分的主要成分。使用高效液相色谱（HPLC）检测到芦丁、阿魏酸和绿原酸为主要酚类化合物。宽果沙芥不同种群间观察到的高度多样性为选择最佳种群并将其用于驯化项目、栽培和育种计划提供了良好潜力。
