Phytotoxic chlorophyll derivatives from Petrorhagia velutina (Guss.) Ball et Heyw leaves.
In this investigation the phytochemical study of chlorophyll derivatives from leaf extract of Petrorhagia velutina, a eurimediterranean plant species typical of macchia vegetation is reported. A new pheophorbide, as well as nine other chlorophyll derivatives were isolated and their structures determined predominantly based on 1D and 2D NMR methods. The phytotoxicity against Raphanus sativus L. was evaluated. A significant photoinduced phytotoxicity was evident for both germination and root elongation.
