The aim of this work was to investigate and compare the antiproliferative, antioxidant and antibacterial activities of Rosmarinus officinalis essential oil, native to Pakistan. The essential oil content from the leaves of R. officinalis was 0.93 g 100g -1 . The GC and GC-MS analysis revealed that the major components determined in R. officinalis essential oil were 1,8-cineol (38.5%), camphor (17.1%), -pinene (12.3%), limonene (6.23%), camphene (6.00%) and linalool (5.70%). The antiproliferative activity was tested against two cancer (MCF-7 and LNCaP) and one fibroblast cell line (NIH-3T3) using the MTT assay, while, the antioxidant activity was evaluated by the reduction of 2, 2-diphenyl-1-picryl hydrazyl (DPPH) and measuring percent inhibition of peroxidation in linoleic acid system. The disc diffusion and modified resazurin microtitre-plate assays were used to evaluate the inhibition zones (IZ) and minimum inhibitory concentration (MIC) of R. officinalis essential oil, respectively. It is concluded from the results that Rosmarinus officinalis essential oil exhibited antiproliferative, antioxidant and antibacterial activities.

“…Monoterpenes, sesquiterpene lactones, and triterpenes are examples of such metabolites that may have commercial usage (Heywood et al 1977;Barney et al 2005). Medicinal plants not only sooth human sufferings but also are used as insecticides (Koschier and Sedy 2003). The use of herbal compounds or plant pesticides goes back a few hundred years in China, Egypt, Greece and ancient India (Pascual-villalobos and Robledo 1998).…”

Abstract:The sweet potato whitefly, Bemisia tabaci (Genn.) (Biotype A: Hem.: Aleyrodidae) is one of the most important pests in Iran. The development of alternative methods that are not chemical applications, is necessary in pest management for the sake of human health and for the safety of the environment. In this research project, the effect of four herbal compounds Fumaria parviflora Lam. The results showed significant differences between herbal compounds and insecticides on: egg longevity (F 6, 39 = 2.96, p < 0.05), pupa longevity (F 6, 37 = 4.49, p < 0.01) and adult longevity (F 6, 31 = 4.47, p < 0.01); egg mortality (F 6, 39 = 6.71, p < 0.001), total egg mortality (F 6, 39 = 6.71, p < 0.001), sex ratio (female) (F 6, 30 = 3.49, p < 0.01), oviposition period (F 6,31 = 7.50, p < 0.001) and total fecundity/female (F 6, 31 = 8.23, p < 0.001).These results indicated that a fumitory extract and pymetrozin had the best effect on longevity and mortality, respectively. According to the results, the fumitory had a noticeable effect on the different life stages of the sweet potato whitefly.

“…Several studies provide evidence that the concentration of plant compounds is critical for repellency as well as for deterrence to thrips (Koschier et al 2000(Koschier et al , 2002Chermenskaya et al 2001;Koschier and Sedy 2003;Sedy and Koschier 2003). While eugenol at 10 and 1% concentration was not repellent to T. tabaci in olfactometer bioassays (Koschier et al 2007), it repelled the onion thrips as the main component (75% eugenol) in clove basil (Ocimum gratissimum L.) essential oil in a field study (Van Tol et al 2007).…”

A series of observational bioassays were conducted to investigate the behavioural responses of the onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), to an application of a secondary plant compound to two different host plants with dissimilar leaf surface characteristics. Eugenol, a phenylpropanoid compound known to deter feeding and oviposition of the onion thrips, was applied to leek (Allium porrum L.) and cucumber (Cucumis sativus L.) at 1% concentration. Using a video system and special software for computing observational data, influences of this plant compound on the behaviour of T. tabaci females were evaluated. Eugenol treatment significantly prolonged the time periods thrips spent being inactive and moving across the treated leek or cucumber surface. The feeding periods on leek leaves treated with eugenol were clearly shorter compared to periods on untreated leek. The behaviours related to oviposition on leaves from both host species treated with eugenol were slightly reduced. T. tabaci females avoided direct contact with eugenol particularly when applied to leek, showing significantly lower contact duration compared to an untreated surface. This shows that behaviourmodifying secondary compounds such as eugenol may be used in various strategies and may contribute to the enhancement of current biological control measures and/or form novel components of Integrated Pest Management strategies.
