Quantitative Investigation Of Total Phenolics Content In Spray-Dried Dandelion Extract Powder

Abstract

With the knowledge that it includes phenolic compounds with antioxidant properties, the herb dandelion (Taraxacum officinale) may benefit health. The total phenolic content of powdered dandelion leaf and root extract produced by spray drying was examined in this work. A UV-Spectrophometric method alongside Folin Ciocalteau reagent, with gallic acid as standard, was used to determine the total phenolic content of powdered dandelion leaf and a dandelion root extract. The results given that the root extract had 9.07 ± 0.54 mg GAE/g as well as the leaf extract showed 32.54 ± 0.49 mg GAE/g. The dried leaf powder measured 9.82 ± 0.11 mg GAE/g, while the dried root powder measured 2.34 ± 0.14 mg GAE/g, in comparison to the dried leaf and root powder. When comparing spray-dried dandelion leaf and root extract powder to traditional dried powders reveals significant variations in phenolic content. Besides, the previously reported hydro-ethanol extraction method was contrasted with the recently investigated hydro-decoction extraction method. Comparing the ethanol extraction method, our hydro-decoction extraction greatly increased the phenolic abundance. The significant amount of phenol in the spray-dried extract indicates that it has the potential to become a widely used antioxidant with a variety of uses.

In conclusion, this work clarified the total phenolic content of powdered dandelion leaf and root extract obtained using a hydro-decoction extraction method followed by spray-drying, pointing out notable variations in phenolic content before and after spray-drying. Further investigation are needed to explore the potential health benefits of dandelion extract and their activity in disease prevention and treatment.
