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 fruits of Zanthoxylum leprieurii Guill. & Perr. (Rutaceae) are traditionally used in Africa, particularly in Cameroon, as a spice and in the treatment of sickle cell anaemia. The objective of this study was to investigate the fruit essential oils from different sample locations and during their maturation period by using GC and GC-MS. Except for one sample collected in Aniak which consisted mainly of oxygenated monoterpenes, the volatile composition of Z. leprieurii fruits exhibited relative high amounts of monoterpene hydrocarbons (61.1-90.9%) such as (E)-β-ocimene (13.4-75.2%) and a-pinene (1.1-40.7%). The influence of the maturity stage on the chemical composition of the essential oils has resulted in an increase of oil yield and variations in the content of volatile compounds (a-pinene 13.3-75.6; (E)-β-ocimene 2.9-64.0%). Keywords: Senegal, Zanthoxylum leprieurii fruits, essential oil, chemical variability, stage of maturity and GC-MS.

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.

The antimicrobial activity, essential oil composition and micromorphology of trichomes of Satureja laxiflora C. Koch, a native plant from Iran, were studied. The essential oil was obtained from the aerial parts at the flowering stage by hydrodistillation, and analyzed by GC and GC/MS. Thirty-three compounds representing 99.1% of the total oil were characterized. The major compounds were thymol (63.9%) and γ-terpinene (11.9%) followed by carvacrol (4.8%), p-cymene (3.9%), geraniol (3.2%) and geranyl acetate (3.1%). Furthermore, the essential oil and its three main components were tested against two bacteria and three fungi. The result of the bioassays has been shown that the oil possesses potent antimicrobial property. Chemical studies confirmed that a major portion of this antimicrobial activity is due to thymol present in the oil. Micromorphological analysis by SEM of both vegetative and reproductive organs revealed the presence of abundant sessile capitate and sparse short-stalked glandular trichomes along with retrorse eglandular hairs, giving useful diagnostic characters for identification of this medicinal plant.
