In Vitro Propagation of Muña-Muña (Clinopodium odorum (Griseb.) Harley).

A micropropagation protocol was developed which may assist in the safeguarding and augmentation of dwindling natural populations of Clinopodium odorum (Griseb.) Harley, a critically and endangered medicinal plant. Factors affecting culture initiation bud sprouting and growth, rooting, and acclimatization were studied, using nodal segments of in vitro germinated seedling as primary explants on six media supplemented with different concentrations and combinations of 6-benzylaminopurine (BAP) (0.

In vitro propagation of "jarilla" (Larrea divaricata CAV.) and secondary metabolite production.

An efficient protocol for the in vitro germination and propagation of Larrea divaricata CAV. (Jarilla) was established. To determine the effect of different growth regulators on the growth rates and phenol production, apical-node microshoots from in vitro germinated plantlets were incubated on the following media: 1) full-strength MS (Murashige and Skoog) salt medium with different ratios of alpha-naphthaleneacetic acid (NAA) and N(6)-benzyladenine (BA); 2) after pre-treatment with indolebutyric acid (IBA), transfer to MS medium of different inorganic salt strengths; and 3) full-strength MS salt medium with different ratios of sucrose and IBA.

Medicinal plants from the "Sierra de Comechingones", Argentina.

Argentina is a country with both rich floral biodiversity and cultural diversity. Traditional herbal medicines are important in the health care of most people, and rely heavily on the use of indigenous plants. An ethnobotanical survey of the "Sierra de Comechingones" made over a 26-year period (1979-2005), indicated that 65 families and 149 different genuses were used in traditional medicines.
