Abstract:
Leaves of Telosma cordata were leached with methanol several times at room temperature, after rejecting solvent at low pressure, methanol were tested cytotoxic activities and antioxidant activities. Results: methanol extracts showed in vitro cytotoxic activities against Hep-G2 (heptonema carcinoma), Fl (fibril sarcoma of uterus) and RD (rhabdosarcoma) with the ED values of 39.0%, 12.6% and 5.6%, respectively. Methanol extracts showed antioxidant activities with SC=52.3±0.9% and IC50=56.9µg/ml. Four compounds: luteine (1), 1-dotriacontanol (2), 24E-stigmasta-5,22-dien-3 B-ol (3), and daucosterol (4) were isolated from the n-hexalle extracts
