TL;DR: A phytochemical investigation of the acetone extract from the immature fruits of Garcinia cowa led to the isolation of two novel tetraoxygenated xanthones, garcicowanones A and B, which exhibited strong antibacterial activity against B. cereus and three Gram-positive strains.

TL;DR: Four new tricycloalternarene derivatives, guignarenones A–D (1–4), along with known (6S,9R)-vomifoliol were isolated from the endophytic fungus Guignardia bidwellii PSU-G11 and displayed mild cytotoxic activity against oral cavity cancer and African green monkey kidney fibroblast (Vero) cell lines.

TL;DR: The purification of the acetone extract from the inflorescences of Garcinia cowa led to the isolation of a new benzophenone derivative, cowanone, together with seven known xanthones, including α-mangostin, which were evaluated for their antibacterial activities against Staphylococcus aureus and methicillin-resistant S. aUREus.

TL;DR: In this article, two new benzopyranones, named coniochaetones E (1) and F (2), one xanthone, penicillone C (3), and one new benzophenone (4) are isolated from the soil fungus Penicillium citrinum PSU-RSPG95, together with ten known compounds.

TL;DR: In this article, three new xanthones, xanthochymones A-C (1, 3), together with six known compounds including two xanthone, three biflavanoids, and one mellein derivative are isolated from the methanol extract of the twigs of Garcinia xanthophymus.
