Acaria saxatilis

Experimental structural results indicate that the unknown, PA-X, may have a structure similar to delphinidin, since the same substitution pattern was observed [82]. The absorption maxima of PA-X showed a 25 nm bathochromic shift upon the addition of A1C13, thus indicating the presence of an ortho-dihydroxyl group in the B-ring [84]. Further analysis suggests that PA-X may also be similar to 8-methoxy-7,3, 4 -trihydroxy-flavylium chloride and 3,8-dimethoxy-7,3, 4 -trihydroxyflavylium chloride which were isolated from the heartwood of Acaria saxatilis by Fourie et al.
