A new pterocarpan, aeschynocarpin (1), and the known pterocarpan 2-methoxymedicarpin (2) were isolated for the first time from Aeschynomene fascicularis (Fabaceae) and their structures elucidated by means of spectroscopic {UV/Vis, IR, and NMR (1H, 13C, COSY, HMQC,and HMBC)} andmass spectrometric (EI-MS and HRCIMS) techniques. Both compounds were tested in vitro for their cytotoxic and antiproliferative activities against a panel of cancer cell lines. This is the first report on the presence of pterocarpans in the genus Aeschynomene.

Article Synopsis
- Aeschynomene fascicularis, a plant used in Mayan medicine, has not been thoroughly studied for its medicinal compounds.
- The root bark of the plant was extracted with methanol, and various fractions were created for testing their effects on cancer cells.
- Compounds isolated from these extracts, particularly spinochalcone A, secundiflorol G, and isocordoin, showed significant cytotoxic and antiproliferative effects against multiple cancer cell lines, indicating their potential as cancer treatments.

Aim Of The Study: To investigate the potential of plants used in Mayan traditional medicine to treat cancer-like symptoms using the Mayan ethnobotany literature, and evaluate their organic extracts for in vitro cytotoxic activity on cancer cell lines.
Materials And Methods: The selection of the plants studied in this investigation was based on the Mayan ethnobotanical information provided by different literature sources. Extracts were obtained by maceration with methanol for 72 h of each plant part used and evaporated in vacuo to give the corresponding dried extract.
