The various components of Psidium guajava Linn. (Guava) leaves and fruit were
extracted using a Soxhlet extractor (organic) and by boiling (aqueous). The crude extracts
were subjected to further fractionation using organic ...
Cobalamin (Cbl) exposed to gases resulted in color changes visible
to the naked eye. These reactions were further analyzed by UV-Vis and IR
spectroscopies. Among gases tested, carbon dioxide, sulfur dioxide and ...
A green and rapid approach was applied in synthesizing water-soluble N-acetyl-Lcysteine
(NAC)-capped ZnSe quantum dots (QDs) in the aqueous phase via
microwave irradiation. The precursors used were relatively less toxic ...
Oil was successfully extracted from Lumbang kernels in which it
was characterized for its properties. FT-IR spectrum showed pertinent peaks
corresponding the presence of functional groups such as ester and sp® C-H
stretching. ...
