Ilmenite is natural mineral ore made up with titanium and iron mineral; including small portion of magnesium and manganese. To the best of our knowledge, photo-degradation of Reactive Black 5 dye (RB 5) using ilmenite under solar irradiation is still lacking. In the present study, the physicochemical properties of ilmenite were characterized by using X-ray diffraction (XRD), Scanning electron microscope...
Two new steroidal sapogenins (1, 2) along with five known steroidal sapogenins were isolated from the acid hydrolysis product of the whole glycoside mixture of Welsh onion (Allium fistulosum L.) seeds. Based on comprehensive spectroscopic analyses, including 2D NMR spectroscopy and mass spectrometry, their structures were elucidated as (25R)-19-norspirosta-1,3,5 (10)-triene-4-methyl-2-ol (1), (25R)-spirost-1,4-diene-3-one-2,6-diol...
