Preliminary findings report antioxidant content in Helichrysum italicum distillation waste, suggesting potential use in various industries.

This study aims to evaluate the antioxidant compounds present in the by-products from Helichrysum italicum steam distillation.
Collected residual biomass from two essential oil producers in north-eastern Bulgaria.
Total phenolic content was measured using the Folin–Ciocalteu method.
Analyzed total flavonoids, fat-soluble vitamins, and β-carotene using spectrophotometry and HPLC/UV.
Total phenolic content ranged from 67.95 to 170.01 mg GAE/g lipid.
Total flavonoid content was between 5.31 and 9.82 mg QE/g lipid.
Fat-soluble antioxidants included vitamin K1 (27–54 μg/g lipid), vitamin E (19–35 μg/g lipid), and β-carotene (8–23 μg/g lipid).

Markova et al. (2026) studied this question.
