TL;DR: Twelve natural products, including two new compounds, were isolated from the bark of the Malaysian tree Goniothalamus borneensis and evaluated for their cytotoxic activity, including goniothalesdiol 1a and goniothalactam 2, which were elucidated by spectroscopy including 2D-NMR spectroscopic.

TL;DR: In this article, the authors performed a phytochemical analysis of the leaf extract of the Malaysian medicinal plant Garcinia gaudichaudii and identified 15 novel cytotoxic compounds.

TL;DR: A bioactivity-directed fractionation of the extracts of the Malaysian plant Garcinia pavifolia and a phytochemical study of G griffithii led to the discovery of griffipavixanthone (1), a novel cytotoxic bixanthones with cyclized prenyl groups providing the xanthone-xanthone linkage as mentioned in this paper.

TL;DR: A Chemotaxonomic survey for biologically active compounds from Malaysian Calophyllum species led to the findings of the four new benzoylcoumarins 1a, 2, 3, 4a, and 4a (including the unusual prenylated 6-benzoycoumann 1a), two uncommon coumarins 5 and 6a with a pyran-4-one moiety fused at C(6) and C(7), and compounds 7a, 9, and 10, all isolated from the bark of C. teysmann

TL;DR: Garcinia gaudichaudii yielded pentacyclic tetra-isoprenylated xanthonoids which exhibited significant cytotoxicity to several cancer cell lines, had their structures determined by detailed spectral analysis as mentioned in this paper.
