Biodegradation of Natural Rubber Latex of Calotropis procera by Two Endophytic Fungal Species
Journal of Bioremediation and Biodegradation, 2017Co-Authors: Nadia H. Mohamed, M. A. Ismail, Wael M. Abdel-mageed, Ahmed Am ShoreitAbstract:In this study eight species related to Aspergillus (3 species), Fusarium (1), Penicillium (1), Emericella (1), Nigrospora (1) and Trichoderma (1) were isolated from leaves and latex of Calotropis procera. Only P. chrysogenium and A. niger were able to grow on natural rubber but other species were not. The degrading ability of (Penicillium chrysogenum and Aspergillus niger), isolated from latex of Calotropis procera was assessed. The degradation of rubber latex was determined by measuring the increase in protein content of the fungus (mg/g dry wt), reduction in molecular weight (g/mol) and inherent viscosity (dl/g) of the latex. Moreover, the degradation was also confirmed by observing the growth of these species strain using scanning electron microscopy.

antioxidant and antiapoptotic activities of Calotropis procera latex on catfish clarias gariepinus exposed to toxic 4 nonylphenol
Ecotoxicology and Environmental Safety, 2016Co-Authors: Alaa El-din H. Sayed, Nadia H. Mohamed, M. A. Ismail, Wael M Abdelmageed, Ahmed Am ShoreitAbstract:Calotropis procera L. is known as medicinal plant. The Phytochemical analyzes of its latex revealed that it possessed antioxidants, namely terpenes, phenolic compounds and cardenolides, flavonoids and saponins, while tannins, alkaloids and resin were absent in moderate to high concentration. In the present study, the role of latex of Calotropis procera as antioxidant and antiapoptotic was reported. To carry out this aim, fishes were exposed to 100 µg l(-1) 4-nonylphenol as chemical pollutant. The enzymes, superoxidase dismutase, catalase, acetlycholinstrase (AchE), glutathione s-transferase, cortisol, G6PDH) and apoptotic cells increased significantly (p<0.05) accompanied by irregular disturbance of (Na(+), K(+)) ions in the presence of 4-nonylphenol. On the other hand, these enzymes, ions, and apoptotic cells decreased normally and significantly (p<0.05) in the presence of latex. Total phenol content, total capacity antioxidant, reducing power decrease significantly (p<0.05) in the presence of 4-nonylphenol and increase normally in the presence of latex. Latex was used for the first time to protect catfish after 4-nonylphenol exposure. Our study confirms that crude latex of Calotropis procera possessed antioxidant and antiapoptotic activities against the toxicity of 4-Nonylphenol.

anthelmintic activity of Calotropis procera ait ait f flowers in sheep
Journal of Ethnopharmacology, 2005Co-Authors: Zafar Iqbal, Muhammad Lateef, Abdul Jabbar, Ghulam Muhammad, Muhammad Nisar KhanAbstract:The anthelmintic activity of Calotropis (C.) procera flowers in comparison with levamisole was evaluated through in vitro and in vivo studies. In vitro studies revealed anthelmintic effects (P < 0.05) of crude aqueous (CAE) and crude methanolic extracts (CME) of Calotropis procera flowers on live Haemonchus (H.) contortus as evident from their mortality or temporary paralysis. For in vivo studies, Calotropis procera flowers were administered as crude powder (CP), CAE and CME to sheep naturally infected with mixed species of gastrointestinal nematodes. Egg count percent reduction (ECR) was recorded as 88.4 and 77.8% in sheep treated with CAE and CP at 3 g kg−1 body weight on day 7 and 10 post-treatment (PT), respectively. CME was least effective resulting in 20.9% reduction in ECR on day 7 PT. It was found that Calotropis procera flowers possess good anthelmintic activity against nematodes, yet it was lower than that exhibited by levamisole (97.8–100%). It is suggested that further research on large scale be carried out involving a large number of animals, doses higher than those used in the current study, identification of active principles, and standardization of dose and toxicity studies for drug development.
