weed chemical control has negative results on agroecosystems. therefore, identification of cultivars tolerant to weeds has importance in nonchemical management. so, in this study, the tolerance of some alfalfa cultivars was studied to dodder. anexperiment was conducted at research farm and laboratory of shahed university in 2011. the farm experiment was done as split plot in time in randomized ...

The use of vegetal extracts requires toxicological and genotoxic evaluations to establish and verify safety before being added to human cosmetic, pharmaceutical medicine, or alimentary products. Persea americana seeds have been used in traditional medicine as treatment for several diseases. In this work, the ethanolic seed extract of Persea americana was evaluated with respect to its genotoxic ...

A study was conducted for assessing quality of 15 hybrid rice seed samples and management of seed borne fungal pathogens by three selected chemicals namely Bavistin (0.3%), Thiovit (0.3%) and Provax (0.3%) along with two botanicals such as: Garlic extract (Allium sativum) (1:1) and Allamanda leaf extract (Allamanda cathartica) (1:1) and a bio-control agent BAU-Biofungicide @ 3% (Trichoderma bas...

UNLABELLED The administration of different polyphenols protects against increased body weight and fat accumulation. The aim of the study was to determine the anti-adipogenic activity of an olive-seed polyphenolic extract, by means of mouse fibroblast cell line 3T3-L1 adipocyte differentiation. MATERIAL AND METHODS Cells were incubated and differentiated (6000 cells/cup) in the presence of oli...

Antimicrobial and antitumor activities of Camellia sinensis L seed extracts were investigated. Seed extracts showed antifungal activities against Candida albicans IFO 1594 and Cryptococcus neoformans. Inhibition zone of 20 mm was shown by 70% ethanol extract against C. albicans IFO 1594 at 100 mg/mL. Antifungal activity of seed extract was not decreased by heating at 80 and 100C for 30 min or a...

The effect of V. vinifera seeds on carbohydrate metabolizing enzymes and other enzymes of the liver in diabetes is currently unknown. We therefore investigated changes in the activity levels of these enzymes following V. vinifera seed extract administration to diabetic rats. Methods. V. vinifera seed ethanolic extract (250 and 500 mg/kg/day) or glibenclamide (600 μg/kg/day) was administered to ...

Cucurbitacins are feeding stimulants for corn rootworm used in baits to control the adults of this insect pest. Corn rootworm larvae also feed compulsively on cucurbitacins. Cucurbitacins are reported to be gibberellin antagonists that may preclude their use as seed treatments for these soil-dwelling insects. The crude extract of a bitter Hawkesbury watermelon containing cucurbitacin E-glycosid...

The anti-feedant and growth inhibitory effects of seed extracts of custard apple in hexane, ethyl acetate and methanol were tested against neonate and 7 days old larvae of the Khapra beetle, Trogoderma granarium, using a feeding bioassay. The LC50 values for hexane, ethyl acetate and methanol extracts were 1195.41, 305.36 and 1446.32 ppm for neonate larvae; 5805, 1300 and 5815 ppm for 7 days ol...

In the present study, the effect of oral administration of Melia azedarach Linn. (dharek) seed extract on fertility index, uterine weight and various histological and biochemical parameters of uterus were studied in the adult cyclic Wistar rats. Average number of embryos and implantation losses in the pregnant animals treated with dharek seed extract was also studied. The extract was prepared u...

Trigonella foenum graecum commonly known as Fenugreek exerts normoglycemic and insulinotropic effects in humans by compounds from its seed and leaf extracts. Some studies reported that treating pregnant mice with fenugreek seed could cause toxic effects on the nervous system of its pubs during developmental growth, while in some other studies neuroprotective properties were considered for it. S...
