Braca Alessandra: Studies on chemical composition from the leaves of Telosma cordata

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
