<p>The aim of this study was to investigate the yield and chemical composition of the essential oil (EO) isolated from over-ground parts of different populations of <em>Hypericum perforatum </em>L. (Hypericaceae) (HP) from southern Albania. The EO yield of 11 specimens of indigenous populations of HP ranged from 2.50 ml/kg to 11.00 ml/kg. GC/FID/MS analyses of the EOs revealed a total of 126 identified compounds representing 77.35–88.29% of the oils. Based on the prevalence of principal components, two types of EO were distinguished: pinene-type, which included seven populations with EO rich in α-pinene, and caryophyllene-type, which included four populations with EO rich in<em> trans</em>-(<em>E</em>)-caryophyllene and caryophyllene oxide. The information obtained can help to assess the potential of the studied Albanian populations for further sustainable wild exploitation to take it into a consideration as a resource of valuable genetic material or for further cultivation and breeding.</p><p>aim of this study was to investigate the yield and the chemical composition of the essential oil (EO) isolated from over ground parts of different populations of <em>Hypericum perforatum </em>L.

Oil Composition

One of the most important families of Iranian flora is Apiaceae (Umbelliferae). Most of the species of this family are aromatic plants and rich in essential oils with diverse structures. In the present review, the essential oil composition of 63 genera comprising 141 Apiaceae (66.4% native 33.6% endemic) is summarized.

Antimicrobial And Antioxidant Activity

Objective: Ziziphora clinopodioides is an edible medicinal plant belongs to the Labiatae family that widespread all over Iran. It used as culinary and also in cold and cough treatments in Iran. The aim of present work was to evaluate the effect of different timeframes during the hydrodistillation on essential oil composition, antimicrobial and antioxidant activity. Materials and Methods: The essential oil of Z. clinopodiodes was extracted via hydrodistillation with Clevenger apparatus. The fractions of essential oil were captured at 6 times from the beginning of the distillation: (10, 20, 60, 120, 180 and 240 min). The fractions of essential oil were analyzed by GC/MS and their antibacterial, antifungal and antioxidant activities were studied by Disk - well diffusion and DPPH methods respectively. Results: Six distillation times and whole essential oil were captured during the hydrodistillation. Essential oil yield dropped off significantly during distillation progressed (1.0% for 10 min and 0.025 for 240 min). 1,8 Cineol, Isomenthone, Pulegone, Piperitenone and Citronellic acid were major compounds in fractions and they were affected by distillation times. Pulegone was major compound in all of essential oils. In antioxidant activity assay, whole essential oil was stronger than was stronger than positive control and fractions of essential oil, because of higher levels of Isomenthone, Piperitenone and Citronellic acid. Strongest antimicrobial activity against S. aureus, E. coli and C. albicans was observed from 10 min fraction. Conclusion: Our results indicated that distillation time can create essential oils with specific properties and we can achieve to more efficient essential oil in short times.
