TL;DR: Most of the isolates demonstrated cytotoxic activity when tested against cultured P-388 cells, with the flavans being more active than the flavones, and certain of these structurally related flavonoids exhibited somewhat selective activities when evaluated with a number of human cancer cell lines.

TL;DR: A new ring-A secotriterpene, koetjapic acid, and five known compounds, 3-oxo-olean-12-en-29-oic acid [2] (a novel natural product), katonic acid [3], (-)-alloaromadendrene, (-)-caryophyllene oxide, and (+)-spathulenol, have been isolated and characterized from a cytotoxic Et2O-soluble extract

TL;DR: From the tubers of Eulophia nuda six phenanthrene derivatives have been isolated: 9,10-dihydro-2,5-dimethoxyphenanthrene-1,7-diol, 9, 10dihdroid-2.5dimethoxide-4methoxymethylphenanthrene -2,7diol; 1,5dimethylphenethylamine-1.7-Diol; and 4,4′, 8,8,8-8′-tetrameth

TL;DR: All butenolides showed cytotoxic activities in several tumour cell lines and the structures of the isolated compounds were elucidated by spectroscopic methods.

TL;DR: A new diarylheptanoid, casuarinondiol, and two known compounds, alnusdiol and (±)-lyoniresinol 2α-O-rhamnoside (a lignan), have been isolated from the roots ofCasuarina junghuhniana and characterized spectroscopically.
