Tavares Increased Antioxidant Activity and Changes in Phenolic Profile of Kalanchoe pinnata (Lamarck) Persoon (Crassulaceae) Specimens Grown Under Supplemental Blue Light Photochemistry and Photobiology 89
This study reports a potential use of blue light as a supplemental light source in cultivation of Kalanchoe pinnata, an important medicinal species. We investigated the effects of blue and UV-A light supplementation on the total phenol content, antioxidant activity and chromatographic profile of K. pinnata extracts. Supplemental blue light improved the antioxidant activity and changed the phenolic profile. Analysis by HPLC of supplemental blue-light plant extracts (A) revealed a higher proportion of the major flavonoid in K. pinnata, as well as the presence of quercitrin and a wide variety of other phenolic substances, when compared with control (B).
