采用气相色谱（GC）和气相色谱-质谱（GC- ms）分析了红花粉茅（Pimpinella khorasanica）地上部、花期花序和种子的水蒸馏精油的化学成分。茎叶、花序和种子油的产量分别为0.3%、2.4%和3.0% w/w。在茎/叶、花序和种子中鉴定出13种、10种和10种化合物，分别占总油分的91.3%、95.8%和91.5%。分析结果表明，其主要成分为(E)- β -法尼烯（48.6%、55.3%和54.1%），其次是ar -姜黄烯（17.8%、10.1%）和青霉烯（6.3%、5.3%）。种子油中的其他主要化合物是pregeijerene（15.8%）和-zingiberene（11.1%）。采用纸片扩散法研究其抑菌活性。方差分析结果显示：
Chemical composition of the hydrodistilled essential oils of the aerial parts, inflorescence at flowering stage and seeds at seeding stages of Pimpinella khorasanica (Umbelliferae Family) were characterized by GC and GC-MS. The yields of stem/leaf, inflorescence and seed oils were 0.3 %, 2.4 % and 3.0 % w/w, respectively. The oil analysis confirmed the characterization of thirteen, ten and ten compounds in stem/leaf, inflorescence and seed accounting for 91.3 %, 95.8 % and 91.5 % of the total oil, respectively. Analysis of the oil showed that it was rich in (E)-beta-farnesene (48.6 %, 55.3 % and 54.1 %) as the main component in all oils followed by Ar-curcumene (17.8 % and 10.1 %) and foeniculin (6.3 % and 5.3 %) in stem/leaf and inflorescence, respectively. The other major compounds in seed oil were pregeijerene (15.8 %) and alpha-zingiberene (11.1 %). Study of antimicrobial activity was done by disk diffusion method. The results of analysis of variation showed that there was significant difference (
