e0“Hosta plantaginea (Lam.) Aschers flowers (HPF) are well-known for their high flavonoid content”
e1“The optimized conditions for TF extraction were determined as 60% ethanol concentration, 30 mL/g liquid-to-solid ratio, 30 min extraction time, and 90 °C extraction temperature, and the extraction ratio is 65.98 ± 2.14%”
