Summary
Plant exosomes, nanovesicles from medicinal plants, show varied yields and antioxidant properties. Artemisia absinthium yielded the most nanoparticles, while Chelidonium majus and Hypericum perforatum exhibited the highest antioxidant activity.
Area of Science:
- Plant biology and nanomedicine
- Phytochemistry and natural products
Background:
- Medicinal plants contain bioactive compounds within exosomes, which are nanovesicles protecting and enhancing compound delivery.
- Plant exosome applications in cosmetics and pharmacy are promising but depend on consistent, high-quality plant material for isolation.
Purpose of the Study:
- To evaluate exosome yield, size distribution, and antioxidant properties from six medicinal plant species.
- To compare nanoparticle characteristics and antioxidant activity across different plant sources.
Main Methods:
- Isolation and characterization of nanovesicles (exosomes) from Kalanchoe daigremontiana, Artemisia absinthium, Hypericum perforatum, Silybum marianum, Chelidonium majus, and Scutellaria baicalensis.
- Assessment of nanoparticle yield, size distribution, and antioxidant capacity (DPPH, FRAP).
Main Results:
- Nanoparticle yield, size, and antioxidant activity varied significantly between plant species.
- Artemisia absinthium produced the highest yield and concentration of nanoparticles.
- Chelidonium majus and Hypericum perforatum showed the highest antioxidant activity per weight and per particle.
Conclusions:
- Plant species specificity influences exosome yield, size, and antioxidant potential.
- No direct correlation was found between plant material and exosome antioxidant activity (DPPH, FRAP).
- Further biochemical analysis is needed to confirm exosome biological activity and its link to the source plant.
