3-O-Methylated flavonols were isolated as crystals for the first time from the flowers ofNeochilenia, Neoporteria andParodia species belonging to the sub-family Cereoideae (Cactaceae), which are native to South America. The structures of three compounds were confirmed by chemical and spectral means. In the tepals of 7 species ofNeoporteria, 3-methyl ether of quercetin was found in the form of aglycone, whereas it was present as the 7-O-glucoside in the tepals ofParodia sanguiniflora and as the 4′-O-glucoside in the tepals of three species ofNeochilenia. Among those two glucosides of quercetin 3-methyl ether, the former has been found in a whole plant ofArtemisia transiliensis (Compositae), while the latter is new to the literature. Therefore, the term “neochilenin” may be assigned to this new pigment.
