background & aim: the plants of the greenhouse have been affected by infestation of the pest trialeurodes vaporariorum, called greenhouse whitefly, which markedly reduced production. synthetic insecticides have been widely developed and, their extensive use has brought about disadvantages, like environmental disturbance, pest resistance, lethal effects on non target organisms and toxicity t...

     Cell cultures of Varthemia persica, Peganum harmala and Pycnocycla spinosa have been studied to evaluate their abilities to bioconvert exogenous hydroquinone. Arbutin is an important substance that has several pharmaceutical applications; therefore, we have established V. persica and P. spinosa cultures which seem to be able to metabolize hydroquinone. C...

Peganum harmala is a plant that is traditionally used as an analgesic, anti-inflammatory, antibacterial, antioxidant, anti-helmintic, and antimutagenic agent. Moreover, it is used to treat a variety of human ailments, including depression. This study was conducted to investigate the antidiabetic activity of hydro alcoholic extract of this herb. A hydro alcoholic extract from seeds of this herb ...

Alkaloid profiles of root and shoot cultures, seedlings and mature plants were analysed by capillary GLC and GLC-MS. beta-Carboline alkaloids, such as harmine, harmaline dominate in normal and root cultures transformed by Agrobacterium rhizogenes, as well as in roots and fruits of the plant. In shoots, flowers and shoot cultures quinoline alkaloids such as peganine, deoxypeganine, vasicinone an...

based on the extensive application of peganum harmala (p.h) seeds in the asian traditional medicine, we tried to investigate its possible anxiety effect. method: the effect of p.h. extract inhalation was evaluated in adult male rats using elevated plus-maze apparatus. the humidity of prepared ethanol extract was 37%. animals in different groups (n=6) received 2, 4, 6, 12 or 18 gr/ml doses of th...

Harmaline (HAR), a natural occurrence β-carboline alkaloid, was isolated from the seeds of Peganum harmala and exhibited potent antitumor effect. In this study, the anti-gastric tumor effects of HAR were firstly investigated in vitro and in vivo. The results strongly showed that HAR could inhibit tumor cell proliferation and induce G2/M cell cycle arrest accompanied by an increase in apoptotic ...
