Evaluation of antioxidant activity index (AAI) by the 2, 2-diphenyl-1-picryl hydrazyl method of 40 medicinal plants
Currently there has been an increased interest globally to identify antioxidant compounds that are pharmacologically potent and have low or no side effects for use in preventive medicine and the food industry. As plants produce significant amount of antioxidants to prevent the oxidative stress caused by free radicals and oxygen, they represent a potential source of new compounds with antioxidant activity. In India and...

Inhibitory activity of Heinz body induction in vitro antioxidant model and tannin concentration of Thai mimosaceous plant extracts
Medicinal plants have been used for traditional treatment and known to possess antioxidant activities that may help to reduce the risk of oxidative stress-related diseases. Chemically-induced oxidative hemolysis is usually associated with the formation of Heinz bodies-insoluble precipitates within red blood cells, indicating the oxidative destruction of hemoglobin. In the present study, antioxidant activity...

The effect of aqueous extract of Salep prepared from root-tubers of Dactylorhiza maculate (Orchidaceae) on the testes and sexual hormones of immature male mice
The use of the salep plant as a fortifying agent and sexual energy is common in traditional medicine. However, the unavailability of sufficient scientific evidence on the effects of sex hormones on the testis and the survey was designed and implemented. In this experimental study, 18 male rats breed immature BALB/C (mean age 4 weeks) were selected and divided randomly into three groups: 1) Control (no feeding), 2)...

In vitro propagation of tuberose (Polianthes tuberosa)
A plant regeneration method has been developed for Polianthes tuberosa. Outer and inner scales of bulb were used as explants. Both explants were cultured on Murashige and Skoog (1962) medium containing 3% sucrose with different concentrations of benzylaminopurine (BAP), naphthalene acetic acid (NAA) and thidiazuron (TDZ). Multiple shoots were induced directly from the scales of explants....
