“…Lavender essential oil helps treat diseases of the digestive tract; it exhibits a diastolic effect for the ileum and smooth muscles (Lis-Balchin and Hart 1997). Thus far, antimicrobial Wilkinson 2002, Adaszyńska et al 2013), antifungal (Moon et al 2007) and antioxidant (Spiridon et al 2011) activities of the essential oils isolated from field-grown plants have been confirmed.…”

“…Essential oils, extracts and dried plants of lavender have been studied for their antioxidant activity using the DPPH, FRAP and ABTS methods (Lee and Shibamoto 2002, Blažeković et al 2010, Hui et al 2010, Spiridon et al 2011, Hamad et al 2013, Proestos et al 2013. Examinations of the capability to scavenge DPPH free radicals demonstrated that extracts from dried in vitro plants of all the tested cultivars were characterized by significantly higher antioxidant activity than extracts of dried fieldgrown plants (Tab.…”

In the study, micropropagation of three varieties of Lavandula angustifolia was developed, and the appearance of trichomes, antioxidant activity of extracts and antimicrobial activity of essential oils isolated from plants growing in field conditions and in vitro cultures were compared. The study evaluated the number of shoots, and the height and weight of the plants grown on media with additions of BAP, KIN and 2iP. The greatest height was attained by the lavenders growing on MS medium with the addition of 1 mg dm -3 2iP -'Ellagance Purple'. The greatest number of shoots was developed by the 'Ellagance Purple' and 'Munstead' plants growing on the medium with 2 mg dm -3 BAP. The highest weight was attained by the plants growing on the medium with the highest concentration of BAP -3 and 5 mg dm . Moreover, the present study determined the influence of media with the addition of different concentrations of IBA and media with a variable mineral composition (½, ¼, and complete composition of MS medium) and with the addition of IBA or NAA for rooting. The majority of the media used had a positive influence on the development of the root system. The longest root system was observed in 'Ellagance Purple' growing on the medium composed of ¼ MS with 0.2 mg dm -3 NAA. All the examined oils exhibited activity towards S. aureus, S. epidermidis, P. aeruginosa, E. coli and C. albicans. The majority of the essential oils isolated from the plants propagated in vitro exhibited stronger antimicrobial activity than the field-grown plants. The plants propagated under in vitro conditions demonstrated considerably higher antioxidant activity as compared with the field-grown plants, which was determined using the DPPH, FRAP and ABTS assay.

“…O. vulgare is used in traditional medicine as diuretic, stimulant, antimicrobial, antiinflammatory, antioxidant and anticancer [12]. Many of these activities have been attributed to compounds including, carvacrol, thymol, rosmarinic acid, borneol, organol, ursolic acid, monoterpene hydrocarbons (limonene, terpinene, ocimene, caryophyllene, β-bisabolene and p-cymene) and monoterpene alcohols (linalool, 4-terpineol) [13][14][15][16].…”

Background: Origanum vulgare is used in traditional medicine for antimicrobial, anti-inflammatory and antioxidant activities. Objectives: The present study was designed to investigate the protective effects of O. vulgare leaves extract on experimentally induced intestinal ischemia/reperfusion (I/R) injury in rats. Materials and Methods:In this experimental study, 24 male Wistar albino rats randomly divided into four groups. Group I/R underwent ischemia-reperfusion of the intestine (45 minutes of ischemia followed by 1 hour of reperfusion). Treatment groups I and II were given O. vulgare extract (200 and 400 ppm) via oral gavages for 1 week before inducing I/R. Group sham was given normal saline orally without inducing I/R. After the experiments, the jejunum was removed and the tissues were processed for histomorphometric examination of mucosa. Results: The treatment with O. vulgare extract significantly decreased mucosal damages in the treatment groups compared to group I/R, while severe mucosal damages were observed in the group I/R. Also, there was significant difference between treatment groups I and II (P = 0.054). Group sham observed normal intestinal mucosa. Conclusions: According to the results of current study, administration of O. vulgare extract protects the intestinal mucosa from I/R injuries.

The blood pressure lowering effect of herbal-rich diet is a necessary dietary lifestyle measure now included the guidelines for the management of arterial hypertension. Flavonoids represent a major class of plant polyphenolics, they have antioxidant effects and show a wide range of pharmacological activities. This study was to clarify the antihypertensive effect of the flavonoid extracted from the Origanum vulgare.Forty five adult male albino rats were classified into three main groups as follows: group I: control. Group II: hypertension was induced by ligation of left renal artery. Group III: hypertension was induced and given OV as 100 mg/kg body weight daily for eight weeks. Blood samples were collected and cardiac sections were stained with H&E and immunohistochemical staining for caspase 3 and Bcl-2.The body weight of control, hypertensive and treated hypertensive groups showed a significant weight gain. Significant increase in creatinine and cholesterol in untreated in contrast to other groups. There was significant reduction of blood pressure (BP) on using OV in contrast to other groups. The hypertension group induced myocardial abnormalities as disruption, vacuolation, inflammation and wide separation of cardiac muscle fibers. Myocyte apoptosis were significantly decreased with OV compared with other groups. Caspases 3 and Bcl2 immunostaining in OV-treated rats were significantly decreased compared with other groups.The supplementation of OV herbetic extract (flavonoid) in hypertensive rats partially prevented such occurred changes, suggesting its possible protective effect against the risk of the progression of cardiovascular diseases during hypertension.
