Abstract
- Micropropagation is a technique to ensure a constant and uniform source of medicinal plants. In this report, we describe the micropropagation of Lepidium virginicum L. ( Brassicaceae), a wild plant used as an antiamoebic in traditional Mexican medicine. In vitro-germinated seeds were cultured in Murashige and Skoog (MS) medium to obtain pathogen-free cotyledons, hypocotyls, and apical bud (AB) explants. For induction of morphogenesis, the effect of cytokinins, benzyladenine (BA) and kinetin (KN), combined with auxin, indole-3-acetic acid (IAA) was evaluated. The best rate of shoot proliferation was induced 15 d after culture on MS mineral medium supplemented with IAA∶KN (0.57∶13.94 μ M) from AB explants. Maximum shoot elongation was achieved without plant growth regulators. The effect of indole-3-butyric acid (IBA) (14.76 μ M) was evaluated for in vitro root induction; 60 d after culture all the shoots had developed roots. All rooted plants were successfully transferred to pots and 100% acclimatized in ex vitro conditions. The methanol extracts from the micropropagated active explants of L. virginicum showed and IC<subscript>50</subscript> antiprotozoal value between 141.90 and 268.53 μg ml<superscript>−1</superscript>.
