Background:
- Sangre de Grado (Croton palanostigma) is a plant with a history of medicinal use.
- The sap contains various bioactive compounds with potential therapeutic properties.
Purpose of the Study:
- To isolate and identify cytotoxic substances from Sangre de Grado.
- To evaluate the cytotoxic potential of isolated compounds against cancer cell lines.
Main Methods:
- Bioassay-guided fractionation was employed to isolate compounds from the plant sap.
- Cytotoxicity was assessed using IC50 values against KB and V-79 cells.
Main Results:
- Taspine was successfully isolated from Croton palanostigma sap.
- Taspine exhibited significant cytotoxicity with IC50 values of 0.39 µg/mL against KB cells and 0.17 µg/mL against V-79 cells.
Conclusions:
- Taspine is a key cytotoxic component of Sangre de Grado.
- The potent cytotoxic activity of taspine warrants further research for its potential as an anti-cancer agent.
