In this study, the effect of water and alcoholic (ethanol) extracts Caper Bush Capparis spinosa L., Cumine Cuminum cyminum L. , Black pepper Piper nigrum Sage Salvia sp. Cat thyme Teucrium polium plants on 4th instar larvae Culex quinquefasciatus have been evaluated .The results showed that extract P. had highest larvae, with 48h LC50 155. 9 ppm followed by ethanol C. 308.2 ,315.1and 791.4 resp...

Phenol was extracted from sebacic acid wastewater (SAWW) using liquid-liquid extraction in batch as well as serial modes by applying different solvent: SAWW (1:250 5:250, v/v). Alcohols (1-hexanol, 1-heptanol, and 1-octanol), castor oil and Aliquat-336® were used for phenol extraction. In a typical extraction experiment involving shaking and allowing for phase separation, phenol (75-96%) can be...

Background: Moringa peregrina (Forssk.) Fiori. is a small tree, which grows in south east of Iran. The shoot and root of M. peregrina contain volatile oil which has several isothiocyanates. Objective: To study the effect of salinity on volatile constituents of root and shoot of M. peregrina. Methods: The experiment was conducted on randomized complete blocks design (RCBD) with 8 treatments...

PURPOSE The study is aimed at finding new antibiotic therapy for aquaculture due to potential of bacteria to develop resistance to the existing therapies. Use of large quantities of synthetic antibiotics in aquaculture thus has the potential to be detrimental to fish health, to the environment and wildlife and to human health. METHODS Antimicrobial potential of volatile oil and fractions of c...

The aim of this study was to investigate the immunomodulatory effects of the volatile oil of ginger (Zingiber officinale Roscoe) in vitro and in vivo in mice. In vitro, the volatile oil of ginger (0.001-10 ng/mL) significantly inhibited T lymphocyte proliferation (P < 0.01), decreased the number of the total T lymphocytes and T helper cells (P < 0.01) in a concentration-dependent manner, but in...

Microwave-assisted extraction of volatile oils (MAE) potentially offers a more efficient and bio-sustainable method than conventional extraction by Clevenger apparatus (CE). This study aimed to optimise the MAE of the volatile oil from Pterodon emarginatus fruits and characterise the volatile compounds. A 2³ full-factorial central composite design and response surface methodology were used to e...

The fatty acid and volatile compound compositions of camellia oil were analyzed in this study. The impacts of the replacement of conventional vegetable oil with camellia oil on the sensory attributes of dried seaweed were also determined. C18:1 (83.59%), followed by C16:0 and C18:2, were the most abundant fatty acids in camellia oil. A total of 11 and 32 volatile compounds were identified in ca...

AIM The aim of the study is to investigate the antibacterial activity of 10 volatile oils extracted from medicinal plants, including galangal (Alpinia galanga Linn.), ginger (Zingiber officinale), plai (Zingiber cassumunar Roxb.), lime (Citrus aurantifolia), kaffir lime (Citrus hystrix DC.), sweet basil (Ocimum basilicum Linn.), tree basil (Ocimum gratissimum), lemongrass (Cymbopogon citratus D...

Trichogonia cinerea is endemic to Brazil and occurs in areas of cerrado and campo rupestre. In this study, we characterized the glandular and non-glandular trichomes on the aerial parts of this species, determined the principal events in the development of the former, and identified the main constituents of the volatile oil produced in its aerial organs. Fully expanded leaves, internodes, flore...

The volatile oil obtained from the cones of Cupressus funebris by hydrodistillation was subjected to anti-inflammatory activity using carrageenan induced paw oedema model using albino mice, Diclofenac sodium was used as standard drug (25 mg/kg body weight, p.o.). The volatile oil (100 mg/kg body weight, p.o.) showed significant anti inflammatory activity.
