Why do you think your paper is highly cited?

The search for suitable sources of bioactive molecules such as phenolic compounds is very intensive at the moment as we are looking for all possible ways to improve our health. Our paper provides results on the antioxidant activity of phenolic compounds isolated from a large number (ca. 100) of plant sources. Plant-originated phenolic compounds could for example be used as functional food ingredients intended to improve cardiovascular health or in pharmaceutical preparations. 

  Does it describe a new discovery or new methodology that's useful to others?

No. I believe the merits of the paper to be in the large number of plant sources screened for possible antioxidant effect. 

  Could you summarize the significance of your paper in layman's terms?

We were able to select the most potential plant sources useful in, for example, functional food production. These sources include edible sources such as berries and non-edible sources such as various tree materials and medicinal plants. In addition, vegetable peels showed strong antioxidant effects. Thus, additional research has focused on the functionalities of these materials as well as on the identification of the phenolic compounds responsible for their functional properties.
