Fabrication and Optimization of Electrospun Shellac Fibers Loaded with Leaf Extract.

Single-fluid electrospinning creates nanofibers from molten polymer solutions with active ingredients. This study utilized a combination of a fractional factorial design and a Box-Behnken design to examine crucial factors among a multitude of parameters and to optimize the electrospinning conditions that impact fiber mats' morphology and the entrapment efficiency of leaf extract. The findings indicated that the shellac content had the greatest impact on both fiber diameter and bead formation.

Preparation of Bioactive De-Chlorophyll Rhein-Rich Extract.

leaves display various biological activities as a result of their rhein and phenolic composition. The objective of this study was to develop bioactive de-chlorophyll rhein-rich extracts. The rhein content was quantified using a validated high-performance liquid chromatography-diode array detection (HPLC-DAD) method.
