Comprehensive profiling of chlorophylls, carotenoids extracts and their derivatives in leaves of fruit tree species and assessment of antioxidant and enzyme inhibitory activities

This study characterizes the chemical composition and biological potential of chlorophyll- and carotenoid-rich extracts (Ch&C.Ex) derived from the leaves of eight fruit tree species: apple, pear, quince, apricot, peach, plum, sweet cherry, and sour cherry. While fruit tree leaves are abundant agricultural by-products, they remain a largely underutilized source of bioactive compounds.

Chemical Profiling

Using LC-PDA-ESI/QTof-MS and UPLC-PDA, the researchers identified and quantified a total of 52 compounds and derivatives.

• Chlorophylls and Derivatives: 19 chlorophyll-related compounds were detected, including native chlorophylls a and b, as well as degradation products like pheophytins, pheophorbides, and hydroxylated derivatives.
• Carotenoids: 10 carotenoid derivatives were identified, including $\beta$-carotene, lutein, violaxanthin, and neoxanthin, along with various cis-isomers.
• Interspecific Variation: Substantial variability was observed among species. Quince leaf extracts were particularly rich in chlorophylls, while pear, peach, and apricot leaves showed the highest proportions of carotenoids.

Biological Activity

The extracts were evaluated for their antioxidant capacity and their ability to inhibit enzymes linked to metabolic and neurodegenerative diseases.

• Antioxidant Activity: Pear and plum extracts exhibited the strongest antioxidant potential in ABTS assays, while quince extracts showed superior ORAC activity.
• Antidiabetic Potential: Sweet and sour cherry extracts displayed the most significant inhibitory activity against $\alpha$-amylase and $\alpha$-glucosidase, suggesting a potential role in attenuating postprandial glycemic responses.
• Neuroprotective and Anti-inflammatory Activity: Apple, pear, and apricot extracts showed notable anticholinergic potential (AChE and BuChE inhibition). Quince extracts demonstrated the most potent anti-inflammatory profile, with significant inhibition of COX-1, COX-2, and 15-LOX.

Key Findings and Applications

Multivariate statistical analyses, including principal component analysis (PCA), heatmaps, and correlation matrices, established distinct relationships between pigment composition and bioactivity. Chlorophyll derivatives were found to be strongly associated with antioxidant and neuroprotective activities, whereas carotenoids correlated more closely with antidiabetic effects.

The study concludes that fruit tree leaves are a sustainable and valuable source of bioactive pigments, offering promising applications as natural preservatives, functional food ingredients, or nutraceuticals. Further investigation into synergistic interactions between these pigments and other phytochemicals, such as polyphenols and triterpenes, is recommended to fully understand their therapeutic potential.

Effect of five dietary carotenoids on antioxidant capability and high temperature tolerance of juvenile Chinese mitten crab, Eriocheir sinensis

This study evaluated the physiological, immunological, and stress-tolerance impacts of five dietary carotenoids—astaxanthin (Axn), beta-carotene (beta-car), canthaxanthin (Cxn), lutein (Lut), and zeaxanthin (Zxn)—on juvenile Chinese mitten crabs (Eriocheir sinensis). Given the susceptibility of juvenile crabs to environmental stressors like high temperatures during intensive culture, researchers investigated these carotenoids as potential “health-protective” feed additives.

Key Findings

• Culture Performance: Dietary supplementation of these carotenoids at approximately 100 mg/kg did not significantly affect growth performance, survival, or hepatosomatic index (HSI).
• Antioxidant and Immune Status: Carotenoid supplementation significantly improved antioxidant and immune indicators in the hepatopancreas and hemolymph. The efficacy ranking of these carotenoids was generally Axn > Cxn > beta{-car} > Lut approx Zxn.
• Thermal Stress Tolerance: The study conducted a thermal stress test at 39.5 °C. The control group exhibited the highest mortality, while the group supplemented with astaxanthin (Axn) demonstrated the lowest mortality, showing superior resilience to high-temperature stress.
• Pigmentation: All five carotenoids effectively enhanced the redness ($a^*$) of the crab’s carapace and hepatopancreas. Astaxanthin was the most effective for enhancing pigmentation, likely due to both direct deposition and the metabolic conversion of other carotenoid precursors into astaxanthin.

Conclusion

The study concludes that while all five tested carotenoids can enhance pigmentation and antioxidant capacity in juvenile E. sinensis, dietary astaxanthin (Axn) is the most effective for improving antioxidant properties, thermal tolerance, and coloration. These results provide a scientific foundation for developing functional diets that mitigate environmental stress and improve crab health during juvenile culture.
