Aroma profile of the essential oil from different parts of Pimpinella tragium and subspecies population

In this research, aroma profile variation among five population from different parts of Pimpinella tragium and its subspecies were evaluated. According to obtained results, the main chemical component of Pimpinella tragium Vill. in (Khoy) was germacrene D in seed with amount of (51.80%). In Pimpinella tragium Vill. (Ghoshchi), the predominant compound included trans-dictamnol (25.30%) in inflorescence, in addition, in the root part geijerene (26.70%) was the major constituent. Pimpinella tragium Vill. (Tabriz-Ahar), in inflorescence sabinine (36.30%), was introduced as the major compound. In the subspecies of Pimpinella tragium Vill. (Mazandaran), in inflorescence, sabinine (37.10%) was identified as the major constituent as well. In Pimpinella tragium (Alvand-Hamedan) germacrene D (43.5%) was identified in inflorescence as the major compound. In general, it seems that the high value of the essential oil composition within and among Pimpinella tragium and subspecies population could provide useful information for conservation and selection of cross-parents in breeding programs.

Automated summary

In this research, the variation in aroma profiles among different populations of Pimpinella tragium and its subspecies was evaluated. The main chemical component varied among different populations, with germacrene D being dominant in Khoy, trans-dictamnol in Ghoshchi, geijerene in the root part of Ghoshchi, sabinine in Tabriz-Ahar and Mazandaran, and germacrene D in Alvand-Hamedan. These findings provide valuable information for the conservation and breeding programs of Pimpinella tragium and its subspecies.
