We have studied the cytotoxic activity of extracts and jacaranone from Senecio leucanthemifolius Poiret. Extracts from S. leucanthemifolius were able to inhibit the in-vitro proliferation of a series of human tumour cell lines. The dichloromethane extract demonstrated effective cytotoxic activity with an IC50 of 20.1 microg mL(-1) on the large cell carcinoma cell line COR-L23. The ethyl acetate extract showed an IC50 value of 5.0 microg mL(-1) and the butanol extract an IC50 value of 6.4 microg mL(-1) on the same cell line. A major active constituent of the dichloromethane extract was shown to be jacaranone, which was demonstrated to have a very strong activity against all of the tumour cell lines with IC50 values between 2.86 and 3.85 microg mL(-1), although it did not account for all the activity observed. Constituents of S. leucanthemifolius extracts were identified by GC/MS analysis and NMR.

Abstract

We have studied the cytotoxic activity of extracts and jacaranone from Senecio leucanthemifolius Poiret. Extracts from S. leucanthemifolius were able to inhibit the in-vitro proliferation of a series of human tumour cell lines. The dichloromethane extract demonstrated effective cytotoxic activity with an IC50 of 20.1 microg mL(-1) on the large cell carcinoma cell line COR-L23. The ethyl acetate extract showed an IC50 value of 5.0 microg mL(-1) and the butanol extract an IC50 value of 6.4 microg mL(-1) on the same cell line. A major active constituent of the dichloromethane extract was shown to be jacaranone, which was demonstrated to have a very strong activity against all of the tumour cell lines with IC50 values between 2.86 and 3.85 microg mL(-1), although it did not account for all the activity observed. Constituents of S. leucanthemifolius extracts were identified by GC/MS analysis and NMR.

The cytotoxic activity of extracts and jacaranone from Senecio leucanthemifolius Poiret is reported. Extracts from S. leucanthemifolius were able to inhibit the in vitro proliferation of a series of human tumor cell lines. The dichloromethane extract demonstrated effective cytotoxic activity with an IC50 of 20.1 g mL-1 on the large cell carcinoma cell line COR-L23. The EtOAc extract showed an IC50 value of 5.0 g mL-1 and the BuOH extract an IC50 value of 6.4 g mL-1 on the same cell line. A major active constituent of the dichloromethane extract was shown to be jacaranone, which showed a very strong activity against all of the tumor cell lines with IC50 between 2.86 and 3.85 g mL-1, although it did not account for all the activity observed. Constituents of S. leucanthemifolius extracts were identified by GC/MS analysis and NMR.
