•
Aromatic Region:
Partial intensity reduction in G2, G5, and G6 peaks indicates moderate structural rearrangements. A shorter drying time at high temperature results in less extensive degradation compared to DD2 conditions.
•
Aliphatic Region:
Methoxy (OMe) and β-O-4 peaks show moderate intensity loss, suggesting aliphatic side chain degradation occurs but to a lesser extent due to the shorter drying duration. This highlights the influence of drying time on structural integrity.
