Ashitaba Polyphenol (Chalcone)
When you cut Ashitaba's leaf or stem, you will see sticky yellow sap. This yellow sap is very unique to Ashitaba and cannot be found in other umbelliferae plants. This yellow sap is very precious because you can collect only several mgs from the cross section of the stem. The main component of this yellow sap is Chalcones, a pigment composition of yellow, and more than 10 chalcones are confirmed. The two types of polyphenols, namely, Xanthoangelol and 4-Hydroxyderricin, are especially rich in the yellow sap and the functionality of these yellow sap has received much attention. JBSL was the first company in Japan that was successful in powderization of "Ashitaba Polyphenol (Chalcone)" and introduced this as a new functional ingredient. JBSL, paying particular attention to the uncovered utility of Ashitaba Polyphenol (Chalcone), is advancing research on its functionality. Ashitaba Polyphenol CHALSAP
