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.

The chemical composition and antimicrobial activity of the essential oils obtained from the flowering aerial parts and ripe fruits of Echinophora spinosa L. (Apiaceae) from central Italy were analyzed by GC/MS. The major constituents of the oil from the aerial parts were β-phellandrene (34.7%), myristicin (16.5%), δ3-carene (12.6%), α-pinene (6.7%) and α-phellandrene (6.2%), and of the oil from the ripe fruits p-cymene (50.2%), myristicin (15.3%), α-pinene (15.1%) and α-phellandrene (8.1%). The two oils showed good antimicrobial activity against Clostridium difficile, C perfringens, Enterococcus faecalis, Eubacterium limosum, Peptostreptococcus anaerobius and Candida albicans with MIC values respectively of 0.25, 0.25, 0.25, 0.25, 2.25, and 0.50%, v/v, and 0.13, 0.13, 0.13, 0.13, 2.25, 0.50%, v/v, for aerial parts and ripe fruits respectively. A less significant antimicrobial activity against bifidobacteria and lactobacilli, very important in the intestinal microflora, was also detected, with MIC values higher than 4.0%, v/v.
