Preliminary investigation of the components of the leaves of Syzigium Malaccenae
The crude extract of S. Melaccense was subjected to rapid chromatography. Fractions 12A and 12B gave a yellow syrup with an orange spherical solid and yellow needle-like crystals respectively while fraction 17 produced yellow-green sugar-like crystals. The three fractions were labeled as AT1, AT2 an...

Preliminary characterization by IR revealed the presence of a monosubstituted aromatic ring in AT1 and the presence of double bonds in AT2. 1985-01-01T08:00:00Z text https://animorepository.dlsu.edu.ph/etd_bachelors/2978 Bachelor's Theses English Animo Repository Syzigium Malaccenae Chemistry |
