In the current study, cornstarch-based antimicrobial and edible films were designed using solution-casting methods. The medicinal plants (, and ) reinforced the gelatinized solution in different concentrations as fillers. The effect of plant extracts on antimicrobial and antioxidant potential, microstructure, barrier, thermal and mechanical properties of cornstarch-based films (SBFs) was investigated using antimicrobial activity, DPPH free radical scavenging values, scanning electron microscopy, X-ray diffraction, water vapor transmission rate, differential scanning calorimetry, and tensile strength. Likewise, it was depicted that the geometric and crystalline structures of medicinal plants' reinforced films remained the same even after processing. The mechanical tests indicated that the plant extracts effects are associated with reduced elongation, increasing tensile strength, and Young's modulus. Morphological analysis revealed the generation of uniform and the compact surfaces. However, films with 10% concentration of plant extracts have the lowest water vapor permeability values, and emerged better barrier properties. Moreover, these films showed the significant antioxidant potential and antimicrobial activity.

Globally, traumatic injuries and severe hemorrhagic wounds resulting from natural disasters, wars, traffic accidents, and operation rooms, especially during birth, are among the most difficult humanitarian and economic problems. Thus, the priority in emergency medical treatment is reducing unexpected blood loss, which can significantly influence a patient's rescue and recovery speed. For the immediate cessation of bleeding in severe hemorrhagic wounds and to speed up their healing, environmentally friendly γ-ionizing irradiation technology was used to develop innovative natural-based hydrogels impregnated with traditional medicinal plant extracts (MPE) with proven hemostatic and bactericidal potential as potential dressings for hemostasis, infection control, and wound healing.

Analytical thin layer chromatography (TLC) is a simple yet powerful chromatographic technique that is widely used for the qualitative characterization of complex mixtures such as plant extracts. For their qualitative and visual characterisation, a large number of more or less specific colour reactions are at hand and numerous reference substances are available as well. However, the identification of extract components by colour and the comparison of retention times is not straightforward.

The effect of solvents with different polarities on the recovery of phytochemicals (carotenoids, capsaicinoids, and phenolic compounds) from habanero pepper (Capsicum chinense) and their association with antioxidant activity (ABTS and DPPH) was evaluated through Ultra-Performance-Liquid Chromatography coupled with a Photodiode Array Detector and a Electrospray Ionization Mass Spectrometry (UPLC-PDA-ESI-MS)-based chemometric analysis, including linear correlation, multiple linear regression, and principal component analysis (PCA). The solvent polarity scale was established according to solvent dielectric constants (ɛ). Color variation (ΔE) was used to determine the presence of carotenoids, with the highest ΔE obtained using low-polarity solvents (hexane and ethyl acetate).
