Description

Application

• Biodegradable polymer enhancements: A study investigated the biodegradability of chitosan films modified with cinnamic acid and ellagic acid, highlighting improvements in environmental degradation rates, which could be beneficial in packaging and agricultural applications (Michalska-Sionkowska et al., 2024).
• Enzymatic studies in alkaloid biosynthesis: Research on the enzymes cinnamate 4-hydroxylase (CYP73A) and p-coumaroyl 3′-hydroxylase (CYP98A) from Leucojum aestivum explored their roles in the biosynthesis of Amaryllidaceae alkaloids, emphasizing cinnamic acid′s importance in metabolic pathways essential for pharmaceutical applications (Desgagné-Penix et al., 2024).
• Quality evaluation in traditional medicine: A metabolomics approach was used to assess the quality of Scrophularia ningpoensis hemsl by identifying biomarkers, including cinnamic acid derivatives, thus providing a method for quality control in herbal medicine production (Lu et al., 2024).
