Bioactive Compounds and Potential Health Benefits through Cosmetic Applications of Cherry Stem Extract

Area of Science:

• Natural Product Chemistry
• Cosmeceutical Science
• Dermatology

Background:

• Cherry stems contain polyphenols and anthocyanins, known for antioxidant and anti-inflammatory properties.
• These compounds are traditionally used and show potential for treating skin aging and diseases.

Purpose of the Study:

• To evaluate the antioxidant and anti-inflammatory effects of cherry stem extract for skincare applications.
• To characterize the chemical composition of the extract and assess its efficacy in inhibiting skin-aging enzymes.

Main Methods:

• High-performance liquid chromatography-electrospray ionization-quadrupole time-of-flight mass spectrometry (HPLC-ESI-qTOF-MS) for extract characterization.
• Assays for total phenolic content, antioxidant capacity, radical scavenging activity, and enzyme inhibition (HYALase, collagenase, xanthine oxidase).
• Formulation of the extract into a cosmetic gel and subsequent stability testing (accelerated and long-term).

Main Results:

• 146 compounds were identified in the cherry stem extract.
• The extract demonstrated potent radical scavenging activity against NO· and HOCl radicals (IC50 values: 2.32 and 5.4 mg/L).
• Significant inhibition of HYALase, collagenase, and xanthine oxidase (XOD) enzymes was observed (IC50 values: 7.39, 111.92, and 10 mg/L, respectively).
• The cosmetic gel formulation containing cherry stem extract showed good stability and compatibility for topical application.

Conclusions:

• Cherry stem extract possesses significant antioxidant and anti-inflammatory properties.
• The extract effectively inhibits key enzymes involved in skin aging.
• Cherry stem extract is a promising, stable ingredient for cosmeceutical and skincare product development.
