Development and Validation of a Simple, Fast, and Accessible HPLC-UV Method for Cannabinoids Determination in L. Extracts and Medicinal Oils.

Introduction: L. is a well-recognized medicinal plant. Cannabis regulations in Argentina are insufficient to solve the problem of patient access to full-spectrum cannabis-based products.

Artemisia magellanica. Chemical Composition of the Essential Oil from an Unexplored Endemic Species of Patagonia.

The essential oil composition of the aerial parts of Artemisia magellanica Sch. Bip. (Asteraceae), native to Patagonia, was analyzed by GC-FID-MS.

Northwestern Argentina: a center of genetic diversity of lemon verbena (Aloysia citriodora PALÁU, Verbenaceae).

The aerial parts of lemon verbena (Aloysia citriodora PALÁU) are worldwide used due to their medicinal and aromatic properties. The essential-oil and acteoside contents have been proposed as the main quality markers for their pharmacological and organoleptic features. The northwestern region of Argentina has been repeatedly proposed as the place of origin for this species.

Identification of the genotype from the content and composition of the essential oil of lemon verbena (Aloysia citriodora Palau).

Aloysia citriodora accessions from cultivated material, botanical collections, and wild populations were studied by means of their biomass and essential oil production and composition to assist the selection of the most promising genotype. The study was carried out through both field experiments during two year's time and laboratory processes. Data were evaluated by means of univariate and multivariate techniques.

Volatile constituents of Aristolochia argentina.

The essential oils from leaves, aerial stems and underground organs of Aristolochia argentina Gris., a medicinal plant popularly known as "charrúa", were obtained by hydrodistillation and analyzed by GC and GC/MS. Forty-three components were identified in the oils.
