Background and objectives: Dorema ammoniacum gum resin is used in Iranian traditional medicine for different indications including inflammatory diseases which are on the rise. Considering the important role of inflammation in different diseases, in the present study, we aimed to investigate the in vivo anti-inflammatory activity and skin toxicity of Dorema ammoniac...
abstract anti-nociceptive activity of aerial parts of phytolacca americana were investigated, using the hot plate method in mice. results of the present study showed that the aqueous methanolic extract of aerial parts of p. americana produced a statistically significant increase in pain threshold after 30 min, in comparison with the control, at adose of 190 mg kg-1 (p<0.001). the activity was c...
Leaves of Catharanthus roseus (L) G. Don (72 kg) were collected from a field grown in the Karachi Uni versity campus. The crude alkaloids (134 g) obtained from the alcoholic extract of the air-dried leaves (24 kg) of the plant, were dissolved in chloroform (450 ml) and extracted with pH 3 phosphate buffer (1 1). The chloroform layer was dried (anhydrous Na2S 0 4), concentrated to 1/3 of its or...
Aqueous extraction of gum from flaxseed was optimized using Response Surface Methodology (RSM). In this study the effect of temperature (45-100 °C), pH (3-7) and water/seed ratio (4-24), on the dependent variables including: yield, protein and apparent viscosity of extracted gum were investigated. The results showed that temperature and pH are two major effective factors on yield and quality of...
physicochemical properties of crude and purified locust bean gums extracted from iranian carob seeds
in this research, seeds of iranian carob trees grown wild in kazeroon city (fars province) were used to extract iranian locust bean gum as a seed galactomannan. chemical composition, solubility, and rheological properties of crude and purified gums were investigated and compared with a commercial (sigma) locust bean gum (lbg) sample. chemical composition of the purified iranian lbg was similar ...
1. Crystalline urease is not inactivated by trypsin in the absence of a gum. In fact, the presence of trypsin alone in aqueous solutions of urease has an action similar to that of gum, that is, it acts as a "protective colloid" for urease. 2. Crystalline urease is inactivated by trypsin in the presence of a gum. This occurs with great rapidity if purified (crystalline) trypsin is used. 3. If tr...
