Cultivo in vitro de tejidos vegetales de plantas del género zephyranthes y evaluación de su producción de alcaloides.

The Amaryllidaceae is a family of bulbous and perennial plants which have been widely known for their ornamental value. The study of this family in the last decade has increased; one reason is because of the large pharmaceutical potential that possesses the alkaloids present in these plants. Genres of this family found in the Valle del Cauca have been endangered due to habitat destruction such as Eucharis and Caliphruria (for example C. hartwegiana and C. subedentata). In addition, other genres like Phaedranasa, Sprekelia, Hippeastrum and Crinum. The Amaryllidaceae alkaloids reported in greater abundance are Licorine and Galantamine. The mechanism of action of these molecules is based on inhibition of the enzyme acetylcholinesterase, showing pharmaceutical use in neurodegenerative diseases such as Alzheimer's. Other alkaloids such Haemantamina, Vittatina and tazetina among others, have presented anti-inflammatory activity, antimalarial and antibacterial
