Abstract
The mealy bugs Nipaecoccus aurilanatus (Maskell) and Pseudococcus albizziae (Maskell) have
been found to contain the novel hypericin monocarboxylic acid (8). N. aurilanatus also contains hypericin(7) and the anthraquinones
(1), (2), (3) and (4) while P. albizziae
contains the protohypericins (13) and (14), skyrin (6) and the anthraquinones (1),
(2) and (3). A reinvestigation of the oxidation ofemodin bianthrone (17) has
provided useful syntheses of skyrin (6) and protohypericin (13), and provided
an unambiguous synthesis of the hypericin monocarboxylic acid (8). The
substance 'isohypericin' (21) could not be obtained by the literature
procedure, reaction affording protohypericin (13) as the only isolable product.
