Artur Manukyan Effects of PAR and UV-B Radiation on Herbal Yield, Bioactive Compounds and Their Antioxidant Capacity of Some Medicinal Plants Under Controlled Environmental Conditions Photochemistry and Photobiology 89
Effects of PAR and UV-B radiation on herbal yield, secondary metabolites (essential oils, polyphenols) and their antioxidant capacity of lemon catmint, lemon balm and sage were tested under soilless greenhouse conditions. Intensive UV-B radiation (2.5 kJ m−2 d−1) influenced the herbal productivity and essential oil composition of all three species, while only essential oil content of lemon catmint and lemon balm was affected. Intensive UV-B radiation was favorable for strong antioxidant capacity of essential oils. Low-dose UV-B radiation (1 kJ m−2 d−1) resulted in high polyphenolic content with strong antioxidant capacity. Polyphenolic composition of herbs was also impacted by PAR and UV-B.
