CYTOTOXIC, ANTIOXIDANT, AND ANTIMICROBIAL ACTIVITIES OF AMPELOPSIS BREVIPEDUNCULATA AND PARTHENOCISSUS TRICUSPIDATA (VITACEAE)

Cyclohexane and methanol extracts of leaves and inflorescences of Ampelopsis brevipedunculata and Parthenocissus tricuspidata are shown to exert significant cytotoxic action on both estrogen-dependent (MDA-MB-361) and estrogen-non dependent (MDA-MB-453) breast cancer cell lines. Methanol extracts of P tricuspidata exhibited higher cytotoxicity for the MDA-MB-453 cell line (inflorescence: IC(50) = 111.45 +/- 2.56 mu g/ml; leaves: IC(50) = 56.76 +/- 7.11 mu g/ml) than for MDA-MB-361. Cyclohexane extracts of A. brevipedunculata leaves exhibited high cytotoxicity against MDA-MB-453 (IC(50) =78.32 +/- 0.1 mu g/ml) and the estrogen-dependent MDA-MB-361 cell line (IC(50) 97.40 +/- 2.61 mu g/ml). The highest DPPH-scavenging ability was exhibited by methanol extracts of P. tricuspidata inflorescences, with IC, 7.55 +/- 0.07 mu g/ml. The tested extracts possessed weak antimicrobial activity.
