| 26-يناير-21 | US16/752,669 | US10898533B1 | Mangosteen nanoparticles | Mangosteen nanoparticles and methods of synthesizing Mangosteen nanoparticles are provided. The Mangosteen nanoparticles may be synthesized by drying Mangosteen, Garcinia mangostana fruit, grinding the dried Mangosteen to form powdered Mangosteen, suspending the powdered Mangosteen in a solvent to form a first Mangosteen solution, spraying the Mangosteen solution into boiling water under ultrasonic conditions to form a second Mangosteen solution, resting the second Mangosteen solution at room temperature (about 20° C.), and freeze-drying the second Mangosteen solution to obtain Mangosteen nanoparticles. The drying step may include either air-drying or freeze-drying the Mangosteen. The Mangosteen fruit peel may be used in the drying step instead of the inner Mangosteen fruit. The resulting nanoparticles may be used in pharmaceutical compositions, and may be useful for their antioxidant and antibacterial activities. | Hany Mohamed Yehia, Manal Ahmed Gasmelseed Awad, Mohamed Fekry Serag El-Din, Hatem Salama Mohamed Ali, Reem Atta Alajmi, Dina Mahmoud Metwally Hasanin, Wafa Abdullah Al-Megrin, Manal Fawzy Elkhadragy | Chemistry/Nanoparticles | A61P31/04 |
| 02-مارس-21 | US16/701,115 | US10934175B1 | Method of making zinc oxide nanoparticles using red sand | The method of producing zinc oxide nanoparticles (ZnO NPs) using red sand includes mixing red sand with water to form an aqueous suspension of red sand, removing the supernatant from the suspension, centrifuging the supernatant and retaining a second supernatant from the centrifuged suspension, dissolving a solution of zinc nitrate in the second supernatant to form a precursor solution, and adding 1M NaOH dropwise to the precursor solution to precipitate the zinc oxide nanoparticles. The precipitate may be washed, dried and calcined to provide the red sand synthesized ZnO NPs. The red sand synthesized ZnO NPs have photocatalytic activity and can be used, for example, to degrade organic dyes in aqueous environments. | Manal Ahmed Gasmelseed AwadAli Kanakhir AldalbahiKhalid Mustafa Osman OrtashiTaghrid Saad Omar AlomarNajla Saad Almasoud | Chemistry/Nanoparticles | C01G9/02 |
| 16-مارس-21 | US16/552,496 | US10947265B2 | Synthesis of ursolic acid nanoparticles | The synthesis of ursolic acid nanoparticles includes dissolving ursolic acid powder in methanol, boiling water for five minutes, and adding the methanol solution to the boiled water dropwise at a flow rate of 0.1-0.3 ml/min under ultrasonic conditions. After sonication for 20 minutes, the contents are stirred for about 15 minutes, and then dried. Particle size distribution studies and TEM micrographs confirm the resulting product comprises nanoparticles. In vitro testing confirms the ursolic acid nanoparticles exhibit greater anticancer activity than conventional-size particles, and that the nanoparticles exhibit antimicrobial effect against gram positive and gram negative bacteria, as well as fungi. | Rabab Abd El Moneim Khalil El Dib, Shaza Mohamed Adel Al-Massarani, Manal Ahmed Gasmelseed Awad, Ali Ali Hasan Elgamal | Chemistry/Nanoparticles | C07J63/008 |
