Genetic Diversity, Chemical Constituents, and Bioactivities of from Thailand.

The genus (Capparaceae) comprises 85 woody species distributed across the paleotropics, with some species used in traditional medicine. This study investigated the phylogenetic placement, genetic diversity, and phytochemical composition of , a species native to Indochina. Phylogenetic analyses using and markers confirmed the monophyly of the specimens collected from Thailand.

Chemical constituents of .

Phytochemical examination of Drake (Rutaceae), collected in Thailand, led to the isolation of seven coumarins, four furoquinolines, two amides, and one flavonoid glycoside. Four of these compounds, one coumarine derivative named as gravelliferone A (), two furoquinoline derivatives (kokusagenin A () and B ()) and one amide, clausenalansamide H (), are reported for the first time. Compound was isolated from the root bark, compound from the stem bark and compounds and from the leaves.
